India is likely to have its indigenous Covid-19 vaccine for children by September, Director of Indian Council of Medical Research (ICMR)'s National Institute of Virology (Pune) Priya Abraham said. Abraham's remarks come amid the ongoing phase II and III trials of Covaxin for the 2-18 age group. "Hopefully, the results (of the trials) are going to be available very soon. The results will be presented to the regulators. So, by September or just after it, we may have Covid-19 vaccines for children," Abraham told India Science, an OTT channel of the science and technology department.

"Apart from Covaxin, Zydus Cadila's vaccine trial is also going on. This can also be applied to children and will be made available. Studies on booster doses have been going on overseas, and at least seven different vaccines have been tried for it," Abraham added. "Now, the World Health Organisation has put a stop to it till more countries catch up with vaccination. This is because there is an alarming vaccine gap between high-income and low-income countries. But, in future, recommendations for boosters will come," he said. Read: India hands over 31 ambulences, other medical equipment to Bangladesh The vaccination programme against Covid-19 started in India on January 16 for people above 18 years. With more than seven months into the drive, so far only 9% of the country's adult population has been fully vaccinated, the figures compiled by Our World in Data showed. The Indian government aims to vaccinate the entire population above 18 years of age by the end of this year. India needs to administer 10 million doses a day to achieve its aim of inoculating the adult population by December, experts say.

US health officials may soon recommend Covid-19 booster shots for fully vaccinated Americans. A look at what we know about boosters and how they could help fight the coronavirus: Why might we need boosters? It is common for protection from vaccines to decrease over time. A tetanus booster, for example, is recommended every 10 years. Researchers and health officials have been monitoring the real-world performance of the Covid-19 vaccines to see how long protection lasts among vaccinated people. The vaccines authorised in the US continue to offer very strong protection against severe disease and death. Read: US okays Covid booster dose for those with weak immune systems But laboratory blood tests have suggested that antibodies – one of the immune system's layers of protection – can wane over time. That does not mean protection disappears, but it could mean protection is not as strong or that it could take longer for the body to fight back against an infection. The delta variant has complicated the question of when to give boosters because it is so much more contagious and much of the data gathered about vaccine performance is from before the delta variant was widely circulating. Delta is taking off at the same time that vaccine immunity might also be waning for the first people vaccinated. France and Germany plan to offer boosters to some people in the fall. The European Medicines Agency said it too is reviewing data to see if booster shots are needed. Read Dengue vs. COVID-19: Symptoms, when & where to test, ways of prevention When would they be given? It depends on when you got your initial shots. One possibility is that health officials will recommend people get a booster roughly eight months after getting their second shot of the Pfizer or Moderna vaccine. Officials are continuing to collect information about the one-shot Johnson & Johnson vaccine, which was authorised for use in the US in late February, to determine when to recommend boosters. Who would get them? The first people vaccinated in the US would likely be first in line for boosters too. That means health care workers, nursing home residents and other older Americans, who were the first to be vaccinated once the shots were authorised last December. Read: US to recommend COVID vaccine boosters at 8 months Booster? third shot? What's the difference? Transplant recipients and other people with weakened immune systems may not have gotten enough protection from vaccines, to begin with. They can now receive a third dose at least 28 days after their second shot as part of their initial series of shots needed for them to be fully vaccinated. For those with normal immune systems, boosters are given much later after full vaccination – not to establish protection, but to rev it up again. What questions remain? Still unknown is whether people should get the same type of shot they got when first vaccinated. And the nation's top health advisers will be looking for evidence about the safety of boosters and how well they protect against infection and severe disease.

Booster shots could crimp already tight global vaccine supplies. What about the unvaccinated? Dr Melanie Swift, who has been leading the vaccination programme at Mayo Clinic, says getting more shots into people who have not yet been vaccinated at all is "our best tool, not only to prevent hospitalisation and mortality from the delta variant but to stop transmission." Every infection, she says, "gives the virus more chances to mutate into who knows what the next variant could be." "People who took the vaccine the first time are likely to line up and get their booster. But it is not going to achieve our goals overall if all their unvaccinated neighbours are not vaccinated," Swift says. Read: Why might COVID-19 vaccine boosters be necessary?

For generations, movies have depicted the ideal man to be one who has bulging biceps and a frame that dwarfs other guys. While bodybuilding is a realistic goal for anyone to get into Hollywood shape, we all have to start somewhere. Often, many correlate muscular arms and chest to the epitome of being buff. What if we told you that despite your good intentions, working on your arms as a beginner is pointless? Here’s why beginners don’t need to train their arms for bulking (at first)! The Excitement Behind Arms Nothing quite shows progress in the gym like your sleeves getting a little too tight for you. Large arms are commonly seen as a testament to your workouts and are tied with your chest to be the most noticeable benchmark for your gains. Exercises like skull crushers and hammer curls are staples in every arm routine and the pump is possibly some of the most out of all arm exercises out there. Despite how alluring short-term pumps can be, it is not efficient to embark on this journey if you are brand new to weight lifting. Read Tips to Get Marathon Level Endurance and Stamina For beginners, the most important thing to do is to establish a routine of compound exercises INITIALLY. Isolation exercises are indeed important but serve to zero in on body parts that are already in the process of being sculpted by compound exercises. Arms certainly fall under the former and arguably have lesser priority than other isolated muscle groups such as lateralis and deltoids. The reason behind this is that compound exercises already engage a plethora of muscle groups and since your arms are used in almost every one of those exercises, they will indeed grow on their own. While working on arms from the get-go is by no means sabotaging your chances of growth, it would be redundant if they were not conditioned for strength and size, to begin with. Many coaches advise beginners to take up more all-rounded exercises, to begin with, such as pull-ups, push-ups, and bench presses for starters. After getting a general sense of what it means to engage your body in weight lifting, bulking starts when separate days are allocated for specific body parts.  Read: Kettlebells: The Best Equipment for Home Workouts Chest Equals Triceps The rule of thumb is that the chest engages the triceps and the back engages the biceps. The bench press should be one of the first exercises you’ve tried when working out with a full-body program. While shoulders, chest, and arms are engaged, the pushing motion of such heavyweights relies on your triceps specifically for the lift-off before your chest is engaged. The incline bench press is also responsible for this, despite technically being an isolated exercise. During the lift-off period, your triceps will be lifting most of the weight for a brief moment, but when your chest begins to carry the weight, your triceps are still engaged.   Despite being a simple exercise on paper, the bench press has been a hot exercise every weightlifter implements due to its versatility. If you are extremely keen to work on your triceps more than your chest, you can follow up from a regular bench press exercise with a close grip version. This puts more emphasis on your triceps, despite going through the same motion as the standard. Be warned that this exercise will require you to reduce the weight on the bar as your triceps will be the main target, and the chest will only provide minimal support.  Read: Best Health Clubs and Gyms in Dhaka in 2021 Back Equals Biceps It’s understandable to be tempted by doing nothing but curls all day to get your biceps popping, but it is one of the smallest muscle groups in your body - and can be put on hold for now. The back has tons of exercises, both isolated and compound, that will have you tucking your arms back at a 90-degree angle - which, in turn, will work on your biceps without a doubt. Classic exercises like bent-over rows, seated rows, and lat pulldowns all possess a pulling motion that isn’t too far off from some bicep exercises, to begin with. Much like the chest, if your primary muscle group is not engaged, you are not executing the exercise correctly. Therefore, learning how to properly activate your back muscles is key to executing the rest of your exercises correctly.  Unlike chest exercises, back exercises don’t quite have the flexibility to pull off alternate grips that can lean more towards bicep-focused workouts. As the back is larger, many of the supposed compound exercises do isolate to a certain extent and will require a lot more time and effort to master the fundamentals. But fear not: since your biceps are biologically one of the smallest muscle groups, it is easily engaged and will definitely grow in proportion to the rest of your body when you have exercised long enough. Read Benefits of Leg Workouts: Why You Should Never Skip Leg Day Mastering The Fundamentals In conclusion, there is a common misconception that massive, chiseled arms are acquired through common arm workouts, but that couldn’t be further from the truth. Attaining the mass alone needs to be done proportionately and that will come when focusing on your entire body. While full-body exercises can be daunting and the results won’t come so quickly, being disciplined and letting time and effort do the rest is critical for your success.  Once your shoulders, back, and chest have had enough time to get accustomed to lifting heavily (with proper form), your arms will definitely catch up with your grown traps and lats. The isolation part comes later when you either feel like you’re hitting a plateau or simply decide that it’s the right time to tone. While arm exercises can be used for bulking, it’s a lot more effort for significantly fewer results.  Read How Effective Are Machines At The Gym?

Earlier this week we reported the government has decided to include pregnant and lactating women in the nationwide Covid-19 inoculation programme amid a worrying rise in Covid-19 hospital admissions across the country. The Directorate General of Health Services (DGHS) issued a notice regarding this Sunday. Although the pregnant women are now eligible for Covid-19 vaccination, they must follow some instructions before getting vaccinated, according to the DGHS. They have to take the Covid shots from government vaccination centres with medical facilities after getting counselling from a registered physician there. Read: Pregnant woman with Covid-19 unlikely to pass infection to newborns: Study Pregnant women, who are unwell or suffering from chronic illness or have a history of vaccine allergy, will not be allowed to take the jabs. Medical experts say there’s no biological reason the shots would affect fertility. And the AP reports real-world evidence offers more assurance for anyone worried about their chances of conceiving: In Pfizer’s study, a similar number of women became pregnant in the group given the vaccine as in the group given dummy shots. Researchers are starting to study anecdotal reports of short-term changes to periods after the vaccine, but there’s no indication so far that the shots put fertility at risk, said Dr. Mary Jane Minkin, a gynecologist and professor at the Yale University School of Medicine. Read: Pregnant, lactating women to get Covid jab: DGHS The US Centers for Disease Control and Prevention (CDC) and obstetrician groups also recommend COVID-19 vaccines for pregnant individuals, who have a higher risk of severe illness if infected with the coronavirus. Research shows pregnant people who get the virus are more likely to be admitted to intensive care, receive invasive ventilation and die than their non-pregnant peers. The CDC also followed tens of thousands of pregnant women who got the vaccines and found they had comparable pregnancy outcomes to pregnant women before the pandemic. So whether you are thinking about having a baby, trying to conceive or undergoing fertility treatments, you should not delay vaccination, Dr. Denise Jamieson, chair of the department of gynaecology and obstetrics at Emory University School of Medicine, told AP.

Each year the heat of the sun is increasing significantly, resulting in a variety of physical problems. One of them is heatstroke. When the body temperature is higher than 105-degree Fahrenheit, it is called heat stroke. It is a serious physical condition that can lead to death. But with a little caution this summer, we can avoid such deadly conditions. Heat Exhaustion vs. Heat Stroke When the external environment temperature rises, our body automatically tries to maintain the internal temperature. As the body temperature rises, the veins in the skin widen and dispel excess heat into the external environment. In addition, the body is cooled due to sweating. However, excessive sweating in extreme heat makes the body lose water and salt. As a result, physical weakness, fatigue, dizziness, muscle aches, extreme thirst, and nausea can occur. This condition is called 'heat cramp' or 'heat exhaustion. If you stay in a humid and hot environment for a long time or if you work hard, it is not possible for the body to control the heat. Rises to 105 degrees Fahrenheit. This is called 'heatstroke.' Read How to heal lungs naturally and improve breathing after recovering from COVID-19? Symptoms of Heat Stroke To deal with the heatstroke, we need to know the symptoms first so that we can take further steps. When the temperature rises in our body, various reactions occur. Initially, there may be less severe heat exhaustion or heat cramps before the heatstroke. Usually, heat cramps lead to pain in the muscles of body parts; as a result, the body feels weak and gets very thirsty. The next stage of heat exhaustion is rapid breathing, headache, dizziness, nausea, incoherent behavior, etc. In both cases, the body heat remains under control, and the body sweats abundantly. Heatstroke can occur if immediate action is not taken in this condition.

As soon as symptoms of heatstroke appear, first, wipe the body with cold ice water to reduce body heat. Also, bring the infected person to a cool environment. Taking off or loosening the body clothes as much as possible will help to reduce the body heat and pass the air. Drink plenty of cold water, fruit juice, or saline. However, if the patient loses consciousness due to heatstroke, the person should be taken to the nearest hospital as soon as possible. Read: Beat the Heat: How to Stay Cool in Simmering Hot Weather? Who has a Higher Risk of Heat Stroke? Heatstroke can happen to any person in extreme heat and humid environments. However, those who work hard in the open field in the hot sun, such as farmers, workers, rickshaw pullers, are more likely to have a heat stroke. If pedestrians walk for a long time under the hot scorching sun, they can have heat stroke. Also, school children playing on the school field under the sun can also have heat stroke. Whoever works long hours in humid and hot environments (such as garment workers) indoors or inside the factory also has risks. Elderly and children contain lower body heat capacity. Hence they are more at risk. Further, dehydration increases the risk of heatstroke. Some medications increase the risk of heatstroke, especially medicines to increase the urine, antidepressants, and psychiatric medications. In addition, older people often suffer from various diseases or take various medications, which increase the risk of heatstroke. Read: Dengue vs. COVID-19: Symptoms, when & where to test, ways of prevention Preventing the Heat Stroke Heatstroke can be avoided by following some precautions on hot days. These are- ·         Try to wear loose and light clothing. Moreover, the fabrics should be white or light in color. Wearing cotton clothing is better. ·  Stay in a shady place or indoor as much as possible. ·  When going outside, using a wide-brimmed hat, cap or umbrella can save you from excessive temperature. ·  Those who are involved in work outside should cover their head with an umbrella or something. ·  Drinking plenty of water and other fluids will keep the balance of salt and water in your body as both salt and water comes out with sweat. ·  Should refrain from consuming tea and coffee as these can increase the temperature. ·  Try to avoid working under the sun in hot weather.

Until now, the epidemic has forced many companies to adopt a work-from-home culture that has stifled the fitness progress of many. Home-based workout content started flooding media platforms, with many experts sharing their tips for a healthy lifestyle when stuck at home. While many bodyweight exercises are easily doable and cost-effective, weight-based workouts are not. Dumbbells and machines are costly due to how many are needed for a properly balanced workout, however, the kettlebell could be the solution. Here is why kettlebells are one of the best equipment for home workouts.  Why Kettlebells? When it comes to viable weights to have at home, only dumbbells and kettlebells are realistic contenders. With machines being ever so bulky and normally serving specific body parts, acquiring enough machines at home to get a well-rounded workout would be ridiculously costly and a strain on your home. The same also applies to barbells. Primarily focused on compound exercises, space barbells have no place for isolated movements. To acquire enough weights for your bar would also rely on having a generous amount of space for stowing. This also applies should you choose to get a rack for the most important activities like squats and bench presses.  Read Tips to Get Marathon Level Endurance and Stamina While it is true that kettlebells and dumbbells offer a variety of weights, kettlebell workouts are vastly different as to how they are performed and can compromise a little more on recycling weight. Lunges, curls and raises are common exercises that target specific muscle groups, and switching up the weights in every set is extremely necessary to see progress. Kettlebell movements are far more dynamic, using drastic motions such as snatches, swings, and cleans. Because of this, it is already clear that the dedicated exercises require the use of more muscle groups than dumbbells.  Read:Pandemic Yoga: How to strengthen lungs, ease breathing problems with yoga Kettlebell’s Uniqueness  To explain why kettlebells have such a unique style of working out, it’s important to examine the weight itself. The kettlebells’ handles, also known as “horns” are measured between six to eight inches, which allows for variety in terms of grip length, which can change up your workout quite dramatically. The weighted part at the bottom is called a bell and it is the main weight the handle is connected to. While dumbbells have a handle for one hand that evenly distributes the weight on both sides, the kettlebell has its weight below the grip, which in turn changes the center of gravity for your workout.  The length of a kettlebell handle was specifically designed to allow single and double hand grips which do broaden the use of the equipment. Because its center of gravity is on the bell itself, snatches and swings have become the ideal way to use it, but in return require far more discipline from the user’s side. Read How to choose the best shoes for running It can be tricky to get both arms symmetrical when executing an exercise, but slight imbalances won’t hamper your workouts too much. Kettlebells however require perfect technique as its style of movement has very little room for error. Twists and bends tend to be clear when it comes to executing wrong techniques and it is easy to identify when your form is askew. Exercises Dumbells Can’t Do If you are not convinced that kettlebells are a better investment, there are many exercises it can do like dumbbells. Single Arm Overhead Raises, Front Raises, SIngle or Double Arm Curls, SInge Arm Rows, and more. While Kettlebells may struggle at the chest department when compared to dumbbells, the kettlebell has a plethora of exercises that the latter will not be able to emulate.  Read:Best Martial Arts For Fitness Kettlebell Swings Possibly the most well-known exercise of them all, the Kettlebell Swing has the person start with their back arched and the kettlebell below that at a 90-degree angle. With both hands, the user will swing the kettlebell forward while extending his/her knees so that the posture is upright while the kettlebell is swung forward. As you can tell, there are many muscle groups activated during this exercise and will require a reasonable amount of practice to get right. Hamstrings, glutes, shoulders, arms, and the core are all worked in a single motion and the kettlebell weight itself puts these muscle groups into tension for growth.  Read Best Team Sports for Weight Loss Kettlebell Goblet Squat Kettlebells definitely have the edge over dumbbells when it comes to squatting. Despite the name, Goblet Squats are not that difficult to do and bears a resemblance to barbell squatting. The standard rules apply: knees are never meant to exceed the feet and the back must be arched when squatting for safety purposes. The only difference is that the user will have to grab the outer edges of the handle with an inward-facing rip. After that, the elbows must be securely tucked together until it is vertically parallel to the rest of the body. If done correctly, your forearms should be hugging the bell. Read Off-Road Vs Road Cycling: Know the Difference Kettlebell Halos Kettlebell halos are definitely unique to this equipment and will need a proper grasp of the technique before increasing the weight. The user will have to grab the handles at its corners and proceed to raise the kettlebell to face level. After that, the hands must be traced around the head as though you are literally drawing a halo. It might sound silly, but this exercise is a shoulder blaster and can give your deltoids, traps, and arms a workout like none other. This exercise will require some initial guidance as the wrong technique and even the wrong weight can have you smack your head during the rotation by accident. Also, if your grip isn’t firm, your elbows could be severely damaged if you drop the ball in the middle rotation.  Read Benefits of Leg Workouts: Why You Should Never Skip Leg Day

There is growing evidence that people who have received COVID-19 vaccines are less likely to become infected with the virus and they are less likely to have symptoms of  severe illness. However, evidence is also emerging that existing vaccines may offer less protection against new variants of SARS-CoV-2, such as the delta variant. Read: Head of UN health agency seeks vaccine booster moratorium Israel has already started to offer booster shots of the Pfizer vaccine to at-risk adults, and the United States is in talks with Pfizer about introducing these shots for the most vulnerable. There has been talk of a third dose for some COVID-19 vaccines. Why might vaccine boosters be necessary, and what are the questions researchers are yet to answer about them?  All data and statistics are based on publicly available data at the time of publication. Some information may be out of date.  One studyTrusted Source, for example, showed that 95% of people who received both doses of the Pfizer-BioNTech or Oxford-AstraZeneca COVID-19 vaccine had a weaker immune response to the delta variant than to previous strains. Read: Pfizer to discuss vaccine booster with US officials Monday People who received just one dose of either vaccine had a very weak immune response, which suggests that a single dose of one of these vaccines does not offer adequate protection. The Health Ministry of Israel also released a statement saying that the effectiveness of the Pfizer-BioNTech vaccine in preventing symptomatic COVID-19 fell to just 64% at 6 months post-vaccination. It noted, however, that two doses of Pfizer are still able to prevent serious illness in 93% of cases. As of yet, the U.S. has made no decision as to whether they will approve access to booster vaccines. However, the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) said in a joint statement that they are “prepared for booster doses if and when the science demonstrates that they are needed.” What are vaccine boosters?  Vaccine boosters are additional vaccine doses that should provide extra protection against disease, as the effects of some vaccines may wear off over time. Vaccine boosters are common for many viral infections, including the flu, which requires a booster every year, and tetanus, diphtheria, and pertussis (DTaP), for which a booster is necessary every 10 years. Read: Can you mix-and-match COVID-19 vaccines? For some vaccines, receiving smaller doses more often is more effective than getting a single large vaccine dose. This approach allows the immune system to build its immune response sustainably. When the immune system remembers certain antigens that previously activated it, it can respond much quicker the next time it encounters them. Although many vaccine boosters are identical to the previous doses, some are modified to enhance their efficacy. The flu vaccine, for example, changes every year to respond more effectively to new mutations of the influenza virus. Why take booster doses?  There are generally two reasons why people might consider vaccine boosters. The first is that immunity naturally wanes over time. Without repeated exposure to certain antigens, the immune system may become less able to prevent infection or disease. Vaccine boosters help the immune system maintain a protective response. “Another reason we may need booster vaccinations is viral variants,” a spokesperson from the COVID-19 Vaccine Team at the University of Oxford told Medical News Today. They went on to explain: “Some variants have evolved to avoid some parts of our immune response, which means they can more easily infect those who have an existing immune response to the virus — i.e., those who have been previously infected or vaccinated. However, the virus cannot avoid all parts of our immune response. A booster vaccination is helpful, as it can improve the parts of our immune response the viral variant cannot avoid.” “Alternatively, we can use a booster vaccine that specifically targets the viral variant. This works by producing a new immune response to the parts of the virus which have changed from the original vaccine whilst also improving the existing immune response against the unchanged parts of the virus, which also should help protect against other variants,” they added. Who should consider a booster shot?  As national agencies such as the CDCTrusted Source note, existing data indicate that most COVID-19 vaccines produce a strong immune response that offers sufficient protection against the SARS-CoV-2 virus. However, it remains unclear for how long COVID-19 vaccines — in the current dosages — continue to offer protection. Nevertheless, booster doses might benefit older individuals or those with a weak immune system,as their bodies may not have generated a strong enough immune response after the initial vaccines. “Based on current data, for people who respond well to the vaccine, it looks like immunity remains strong for over 12 months and works even against the new variants,” Dr. Richard Stanton, a reader in the Division of Infection and Immunity at Cardiff University in the United Kingdom, told MNT. “My personal opinion is, therefore, that we don’t need to be too worried about boosting them yet,” he said. Dr. Jessica Justman, associate professor of medicine in epidemiology at Columbia Mailman School of Public Health, further explained that “[b]ooster shots might be most beneficial for those who have medical conditions — such as some solid organ transplant recipients (e.g., kidney transplant) and some individuals with autoimmune diseases (e.g., lupus) — that prevent them from developing an effective immune response after the first round of vaccination.” However, she added, “[w]e would first need evidence that a booster shot for these individuals is safe and effective.” Other scientists say that the opportunity cost of not providing booster vaccines outweighs the lack of research underpinning their use. In an interview with the BMJTrusted Source, Prof. Anthony Harnden of the Joint Committee on Vaccination and Immunisation in the U.K. expressed the opinion that the U.K. is likely to roll out booster vaccines and that annual boosters might be necessary for some time. Controversies around vaccine boosters “Scientifically, there is nothing controversial about additional booster vaccinations; they work in very much the same way as a second vaccine in a two-vaccine schedule,” the Oxford COVID-19 Vaccine Team spokesperson told MNT. “The debate around additional vaccines is whether they are needed at this stage or [whether] vaccine doses are better off being used elsewhere — particularly in poorer countries, as highlighted recently by Sir Andrew Pollard in an article in The Times newspaper,” they added. Sir Andrew Pollard, director of the Oxford Vaccine Group at the University of Oxford, wrote that the main purpose of vaccines is to “keep people out of hospital.” As vaccines seem to reduce hospitalizationsTrusted Source with COVID-19 significantly, and experts predict that vaccine supplies will be limited for the foreseeable future, Sir Andrew argues that it is important to prioritize those who have not yet had even a single shot before providing boosters to others. Some people even question whether it is morally right to give booster shots to those who have already been vaccinated when many people, especially those in developing countries, have not received even one shot and are thus at a higher risk of infection.   Source: Medical News Today

​​​​​​​After recovering physically from COVID-19, patients may suffer from numerous problems. As time goes on, it becomes clear the effects of COVID-19 infections on the human body, especially in the lungs. However, it may take a long time for many to return to normal life. So even after recovering from corona, caution and care are needed. Experts say that the novel coronavirus has a big impact on the lungs, heart, and mental health. Increasing long-term risk. For mental health, a few sessions with a psychiatrist will be good enough. For the lungs, the patient should have patience and take care of it to improve the breathing after recovering from COVID-19. Post-COVID Effect on Body COVID-19 emerged as a curse in our world. Coronavirus doesn’t just stop after infecting us, and it may create a long-term effect. However, a regular body checkup can identify any potential long-term effects. The following are the most common effects a COVID recovered patient may feel.

The patient can face problems climbing the stairs or have breathing issues while climbing. Especially, the patients who stayed in the Intensive Care Unit (ICU) are taking longer to return to normal breathing conditions.   - Even after corona has recovered, the patient may have a cough for a few weeks.   - The recovered person may not be able to take regular foods sometimes. Even face problems in chewing or swallowing food. Patients who were in the ICU or given a tube in the throat are more likely to face this particular problem. Further, some people may face problems with their voices and face difficulties in speaking.   - After coronavirus infection, a large number of patients experience mental disorders. Problems like attention and thinking problems, memory loss, and depression can occur.   - Weight with fatigue and constant tiredness. It may take some time to get back to the previous weight. Most of these problems will be okay over time by taking enough nutrients. But, special care for the lungs is needed for fast recovery.

Pulmonary fibrosis is a disease in which the soft parts of the lungs become stiff, causing sores. As a result, the airways in the lungs cannot function properly. Most patients with Corona disease have mild symptoms, and many have no symptoms at all. Very few patients face severe complications and are hospitalized. Among infected patients who need oxygen, they are at higher risk of developing post-COVID pulmonary fibrosis. If you have pulmonary fibrosis, a doctor’s consultation is necessary.

Shortness of breath, dry cough, chest pain or pressure, weight loss, mild fatigue, and pain in the muscles and joints after coronary healing are suspected to be complications of the lungs. To detect pulmonary fibrosis, chest X-ray, computerized CT scan of the chest, echocardiogram, pulmonary function testing, and pulse oximetry should be done. Without proper treatment of pulmonary fibrosis, long-term complications such as pulmonary hypertension (high blood pressure in the pulmonary arteries), heart failure, lung cancer, and frequent lung infections can occur.

So, first of all, it puts its paw in the lungs, and the body’s oxygen level also decreases. Even if the corona is gone, the efficiency of the body decreases. Although this risk is not immediately relieved, some methods increase oxygen circulation in the lungs. This gradually removes the weakness of the body and restores efficiency. Deep Breathing Exercises Hold the breath for a long time, as long as possible with the chest full. After that exhale slowly. As a result, the lung cells are exercised, so there is no permanent damage to them. Doctors advise sitting comfortably with your back straight. After that, all the air in the lungs should be expelled through the mouth. Then take a deep breath and fill the lungs with air as much as possible.

This will eventually increase the lung’s efficiency. Sleeping on your Chest Coronavirus infection often causes a lack of oxygen in the human body. This is due to a decrease in the efficiency of the lungs. Therefore, if you are lying on your chest or lying on your side, the supply of oxygen to the body increases. Doctors advise not to use any pillow while lying down like this. Raise your hands while breathing Raising your hands while breathing is a good exercise for the body parts with breathing. Besides, when you take a deep breath, you can put your hand under the ribs of the chest and feel that the chest is swollen like a balloon. Then you have to push it out again. It can be done several times a day.

Hold your breath for 5/10 seconds. Then exhale. Then hold the right side of the nose and breathe in the same way. In the same way, hold for 5/10 seconds and exhale. Practice this way several times a day. Walk Try to walk regularly after recovering from the corona. In this way, you can understand the state of breath in your body. Normally, the amount of oxygen in the lungs is less than before, so you will breathe less, which is completely fine in this condition. Walking slowly every day will increase the efficiency of the lungs.

People with chronic heart or lung disease must consult a doctor before exercising. If you face difficulty in breathing or feel sick during exercise, stop the exercise immediately and take a rest. If the problem is more, you need to contact the doctor.

We all have a tendency to forget, get confused, or sometimes focus on the wrong things. This can be due to overloading of information, stress, distraction and other reasons. These occurrences are normal, and we get over them naturally or after taking some rest. But things get complicated when you consciously forget everything and your brain fail to create a new memory. However, this might seem unreal to you, but this can happen to anyone due to medical reasons such as damage to the central nervous system. You will be surprised to know that we have very few cases in the real world, while we have numerous characters in books and movies. "Notable examples include Lucy Whitmore in 50 First Dates, Dory in Finding Nemo and Finding Dory, Jonathan Archer in the Star Trek: Enterprise episode, Sanjay in Ghajini and more." This kind of memory loss is defined as Amnesia. However, the real-life case of Clive Wearing's memory loss is different. Usually, there are two types of memory loss diseases, anterograde Amnesia and retrograde Amnesia. While the most fictional characters we have mentioned here suffer from either anterograde or retrograde, Clive Wearing suffered from both, and it is the "most devastating case of amnesia ever recorded." 83-year-old British musician Clive has a memory of 7 to 30 seconds only. Read Dengue vs. COVID-19: Symptoms, when & where to test, ways of prevention Who is Clive Wearing? Born in 1938, Clive Wearing was a British musicologist, keyboardist, conductor, and tenor. He was successful in his career and was known for editing the Orlando de Lassus. Further, he sang at Westminster Cathedral for many years as a tenor lay clerk. Besides, he was also a chorus master and worked with the London Sinfonietta Chorus as well as with Covent Garden. Apart from these, Wearing founded the Europa Singers of London in 1968 and performed in numerous places such as the London Opera Centre, Monteverdi Vespers, Russian Cathedral, etc. In 1981 he worked for BBC and made special content for BBC Radio 3 on the "day of the royal wedding of Prince Charles and Diana Spencer." Despite his eventful career, Clive Wearing cannot remember much of it due to his rare medical condition. Read: Harmful Effects of Mobile Phones on Children’s Health What Happened to Clive Wearing? In 1985 when he was 45 years old, Wearing contracted "herpesviral encephalitis which is a herpes simplex virus." This simple virus attacked his central nervous system. After that, he could not store new memories. Besides, he has also been unable to put together his past memories. He is also unable to control emotions and has an unstable mood. Later it was found that Wearing has been having this problem due to total Amnesia. As his hippocampus was damaged, he is totally unable to form new memories; because of that, Clive's memory lasts between 7 and 30 seconds. Hippocampus is an area in our brain that needs to transfer memories from short-term to long-term memory. Every day he wakes up every 20 seconds, which means his consciousness restarts every 20 seconds. During this time, he keeps questioning why he has not met a doctor. Wearing continuously believes that he just wakes up from the comatose stage. Further, if he engages in a discussion, Wearing cannot stay in the flow for more than 30 seconds. Sometimes he forgets the context in 10 seconds and starts again. He cannot speak longer than a few sentences. But Clive remembers a few memories of his life before 1985, such as his love for the second wife and his children from the first marriage. Every time he meets with these people, he greets them joyously, and cannot remember their names. He has featured in many documentaries, and some researchers also conducted research about his condition. Moreover, many fictional movies have been made on Amnesia that we have mentioned earlier. But if you want to visualize the memory loss, you can watch a Bangla drama "Chirokal Aaj" to better understand the amnesia condition. Chirokal Aaj has recently become a center of attraction in Bangladesh. It was based on Clive Wearing's attack on anterograde Amnesia and retrograde Amnesia.
