When a COVID19 infected person coughs for a single time, this action can spread up to 3,000 droplets of corona virus (SARS-CoV-2) in the surrounding air. It is estimated that the airborne droplets can carry active and possibly infectious Corona Virus for about three hours. These Corona Virus droplets can be spread from one person to another if those people stay in close contact measuring less than two meters.
However, if an individual comes in contact with surfaces upon which the Corona Virus droplets have landed and haven’t been disinfected yet, then that person may get infected by COVID19. Furthermore, the droplets of corona virus (SARS-CoV-2) can also spread in the air through the actions of exhaling and speaking.
The survival period of Corona Virus SARS-CoV-2 can definitely be affected by factors like temperature and humidity. According to the Centers for Disease Control and Prevention (CDC), the new corona virus can survive only for a shorter period at higher temperatures and humidity levels. It is found that the new corona virus (SARS-CoV-2) remains highly active at 4°C Celsius (about 39°F). On the other hand, it becomes rapidly inactivated at 70°C (158°F).

The destructive effect of COVID-19 outbreak is still continuing. On the other hand, the summer heat waves are worsening people’s health conditions. In this scorching heat it is quite annoying to stay inside large commercial places, industries, offices and even homes. However, many people are asking whether using Air Conditioners (ACs) during COVID19 pandemic is safe. For several months debates are going on this issue among scientists, engineers, authorities and general people. However, let’s discuss some guidelines about how to use ACs (Air Conditioners) safely amid COVID19 pandemic.
Considering the climate of Sub-continent countries, ISHRAE (The Indian Society of Heating, Refrigerating and Air Conditioning Engineers) has recommended some guidelines regarding how to run air conditioners safely during the coronavirus pandemic. These suggestions can be helpful for operating ACs in different commercial and industrial places in Bangladesh.
What would be the ideal air conditioner temperature for your room during the COVID19 pandemic? According to the recommendation of ISHRAE and CPWD, for any home-run AC, like Room AC, Split AC or Window AC, the temperature level of should be kept within the range of 24 to 30 degrees centigrade.
In addition to this, ISHRAE emphasizes to maintain the relative humidity of indoor environment. You can easily check the humidity of your surrounding ambient through downloading any ‘Weather App’ on your Smartphone. The ISHRAE guideline says that the humidity of an indoor environment should rest between 40 and 70 percent.
Therefore, if you are living in humid climate, then you need to keep the AC on ‘cool’ mode and set the temperature closer to or at 24 degree centigrade. On the other hand, when you are staying in a dry climate area, then you must set the temperature close to or at 30 degree centigrade.
ISHRAE report states that when we breathe dry air, the mucous membrane of our lungs becomes dry. It thickens the fluid over lining of the cells, and hampers the actions of cilia – the little hairs which protect the lungs from deep settling of harmful and non-harmful particles. As a result, the alien particles can settle more deeply inside our lungs.
To prevent such mishaps in the dry climate zones, ISHRAE suggests running electric fans to enhance the air circulation while AC is operating. You can also apply exhausting electric fans which will push the hot air outside the room. However, you need to clean the fan blades frequently to keep the indoor air clean.
What precautions should be taken while using ACs? Instead of allowing recirculation of the same air inside an indoor space, ISHRAE also suggest keeping the windows slightly open to let the fresh outdoor air enter the room.
When you are staying in a room, keep the opposite-facing window and door slightly open to promote cross-circulation of fresh cool air. Though opening a window or door – while running AC – might lose some cool air and cost you more electric bill at month-end, it can help to keep the indoor air fresher.
What precautions should be taken when you are using an evaporative cooler or dessert cooler? To combat the soaring temperatures, you can fit in an air filter in an evaporative cooler in order to keep the dust away and preserving hygiene of the indoor environment. However, make sure that your cooler is capable of drawing outdoor air efficiently to assist proper ventilation. The opposite-facing windows and doors must be kept open slightly to reduce humidity.
Besides, evaporative cooler, other type ACs must be fitted with filters. The ISHRAE guideline recommends cleaning and disinfecting the air cooler on a regular basis. More importantly, the released water must be drained and refilled frequently. The routine servicing of AC is also necessary to avoid any malfunction.
And, the opposite-facing windows must be kept open to ensure proper ventilation. ISHRAE guideline discourages people to use the portable air coolers that can’t draw fresh air from the outdoor environment.
According to the views of engineers and health-experts, using the window air conditioners at residential setting can be safe if the people who share the space with don’t carry corona virus. However, problem may arise when you are staying in a building which uses central cooling. If one infected person stays inside the building, the central air cooler poses a high risk of spreading the corona virus to other people staying there unless adequate precautions – such as, outdoor air ventilation, temperature and humidity control, AC filtering procedures, etc – are taken properly. These central air conditioning systems are widely used in shopping malls, government offices, hospitals, corporate workplaces, industries, etc. So think before you enter those places!
Vitamin C is one of the most essential nutrients for human-body. During the ongoing Coronavirus pandemic many health experts are advising people to consume Vitamin C every day. The recommended Daily Value (DV) for vitamin C for an adult is about 90 mg for male and 75mg for female per day.

Broccoli is a green cruciferous vegetable. Per 100g amount of Broccoli contains about 89 mg of vitamin C. One-half cup amount of cooked broccoli can provide about 51 mg of vitamin C (57% of DV). Researches show that a regular consumption of vitamin-C enriched Broccoli can lower oxidative stress, cuts down the risk of cancer, heart disease, and improves immunity.
A study reveals that 27 heavy smokers were served with 250-gram steamed broccoli (146 mg of vitamin C) every day. After 10 days, 48% decrease was found in their inflammatory reacting compound. Therefore, regular consumption of broccoli may reduce the risk of inflammatory diseases.
Per 100g amount of Lemon delivers about 77mg of Vitamin-C. One whole raw lemon including skin contains about 83 mg (92% of DV) of vitamin C.
