Covid-19 – Is it safe to use AC During Corona Virus Pandemic.

With summer’s driving up temperatures, a question being asked is whether we should use air-conditioners during this pandemic. Several researchers have predicted that the novel corona virus is unlikely to survive high temperatures. As we know, the second wave of Sars-Cov-2 or the Covid -19 is much harmful than the previous one. This question often comes to our mind that, should we use air conditioners during the covid pandemic, or does the virus becomes more harmful when you use air conditioners? Although it’s not stated that using an air conditioner is dangerous during the pandemic but keeping your body warm during these times will surely keep you safe from the virus. It becomes necessary to use air conditioners during summers as the temperature is too high. But you also have to balance the environmental changes accordingly.


  • Turn off the AC and open the window if someone in your house has COVID-19, or has been exposed to the virus
  • If you have air-conditioning on almost all the time, and a sick person in the house, it’s a good idea to limit the flow through your home
  • Don’t let it get too cold. Having proper ventilation is a crucial part of preventing infection


Here are a few points which you need to take care of while using air conditioners during covid:

Temperature Control:

You should set the temperature of your air conditioner ranging between 24-30 degrees. In which 24 degrees is for humid zones and 30 degrees is for dry zones. Today’s advanced air conditioners can control precise temperature and thus ensuring no under or overcooling.

Ensure Proper Ventilation:

Ensure that proper ventilation takes place in the room where the air conditioner is in place. Make sure to open all the windows after you turn off the air conditioner while leaving the room. Place a bowl of water while you are using the air conditioner.

Cleaning air filters more frequently:

Cleaning your air filter is necessary as it helps to maintain the air quality of your room. A dirty air filter may carry dust particles along with them which may deteriorate the air quality of your room. You need to make sure that you clean your air filter at least once a month.

Increasing the rate of air change:

According to guidelines provided by WHO, we can reduce the spread of covid by increasing the rate of air change in indoor spaces. Avoid recirculation of air as it may be harmful.


Following are the three ways to avoid catching the virus indoors-

For the past year, we’ve been asked to wash our hands and maintain social distancing to fight corona virus. But scientists and engineers say we also need to think about the air we breathe inside our home.

1. If it’s stuffy, just walk away

When you enter a room and the air feels stale or hard, something is suspicious with the ventilation. Not enough fresh air is being introduced, which increases your risk of getting infected by covid-19. Recent research shows that in constricted spaces there can be “airborne transmission” of the corona virus – with tiny virus particles remaining in the air.

According to some regulations set up before this pandemic, everybody should get at least 10 liters of fresh air every minute, and that matters more than ever now in this situation.

 2.Look up at the air conditioning

From offices to shops, air conditioning is the most wanted thing on hot days – but check the type of unit. The best is a slender white box mounted on walls which is known as a split air conditioner.

This draws in the air from your house, chills it, and then blows it back out again. In other words, it’s circulating the air again and again.

3. Ask about the ‘fresh air ratio’

In most of the buildings these days, where the windows are sealed, how can one get enough fresh air?

You’re relying on a ventilation system. Right? In which stale or hard air is extracted from the rooms and piped to an air handling unit, often on the roof. There, fresh air can be pulled in from outside and mixed with the already existing inside air, before being sent back into the building.

Given the risk of corona virus infection, professional engineers and scientists have advised maximizing the fresh air supply.

“The more enough fresh air, the less you’re at the risk of recirculating the virus through your building.”

Covid Vaccine : Effectiveness and Efficiency

You might be among the more than 138 million people in India who have taken at least one dose of a coronavirus vaccine. Or you may still be waiting for your turn. Regardless, there’s a question on most of our minds: How long will the vaccine really protect us? 



According to the report of Times of India, “Is vaccine really safe?” is second on the list of Top Ten Most Searched Questions on Google.

As with most aspects of the virus, the appropriate answer is not clear. Why? Because despite the fact that we have been battling the pandemic for over a year now. The vaccines were granted emergency use authorization relatively recently. So specialists have not had time to observe their long-term effectiveness till now.

According to some experts, When you get the vaccine, it takes some time for your body to build an immune response that’ll keep you protected and safe. Because of all these factors, Doctors are asking people not to let their guard down even after getting vaccinated.

In other words, it’ll take time for the vaccine to kick in, and we should still plan to play it safe after getting Vaccinated.


What happens to your body after getting a vaccine dose?

According to WHO, the COVID-19 vaccines produce protection against the virus, as a result of developing an immune response to the SARS-Cov-2 virus. Developing immunity with the help of vaccines means there is less risk of developing the illness and its consequences.

Different types of vaccines work in different ways in providing protection. Yet with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes as well as B-lymphocytes that will remember how to battle that virus later on.

It usually takes 1-2 weeks after immunization for the body to create T-lymphocytes and B-lymphocytes. That’s why it’s possible that a person could be infected with the virus that causes COVID-19 just before or just after getting the vaccine dose and then get sick as the vaccine did not have enough time to provide protection and immunity.

In some cases after vaccination, the process of building immunity can cause symptoms, such as fever. These symptoms are absolutely normal and are signs that your body is building immunity.

Do some Vaccines Require More Than One Shot?

To be fully safe and protected, you will need two shots of some COVID-19 vaccines.

  • Two shots: Pfizer-BioNTech and Moderna COVID-19 vaccines offer two shots.  You are considered fully vaccinated and protected, two weeks after your second shot If you get a COVID-19 vaccine that offers two shots,
  • One-Shot: Johnson & Johnson’s Janssen COVID-19 vaccine only offers one shot. If you get a COVID-19 vaccine that offers one shot, you are considered fully vaccinated two weeks after your shot.

 If it has been less than two weeks since your shot, or if you still need to get your second shot, you are NOT at all fully protected. Keep taking all prevention steps until you are completely vaccinated.

Precautions to be taken after getting vaccine shot.

Even though most of the vaccines that are being used across the country have undergone multiple trials and have been found to be effective in these trial phases. But we still don’t know if these vaccines offer complete immunity or not. We don’t even know how long the vaccines will continue to be effective for us. For now, we can all take heart in the fact that the vaccines will help us fight against the coronavirus.

Here are a few precautions for COVID-19 that all responsible citizens should follow even after vaccination-

  • Continue maintaining social distancing and avoid crowded places like malls, restaurants, and markets, etc.
  • Please don’t forget to wear a mask and sanitize your hands.
  • Encourage and help others as much as you can to register for the vaccination.

Vaccination is one of many steps that you can take to protect yourself and others from COVID-19.  Protection from this virus is critically important as for some people, COVID-19 can cause a serious problem or even death.

Ending this pandemic requires using all the tools available. Vaccines work with your immune system so that your body will be ready to battle against the virus if you are exposed.
