Can We Expect That Cooler Temperatures Will Affect COVID-19?

cooler-temperatures-will-affect-COVID-19

It’s well known that the start of Spring signals the end of America’s flu season. As the temperature warms up, the number of people who catch the influenza drops dramatically. So it’s natural that, as the weather cools off and we’re in a global pandemic, people are asking: How will cooler temperatures affect COVID-19? 

When Covid-19 hit late last winter, hope reverberated around the country that it would dissipate with warmer and sunnier conditions. But as much as the weather affects the flu, it doesn’t do much for COVID-19. That’s why we still saw rising cases this summer — even with warmer weather, the end was not any more in sight. So what can we expect now that cold weather is once again on the way? The reality is this: the risks of a second wave are real, and we’re not quite sure yet exactly how cooler temperatures will affect COVID-19. 

Scientists remain divided on why winter is flu season in the Northern Hemisphere, but one of the most popular hypotheses is the increased time spent in sealed indoor environments. Another is a lack of sunlight, which compromises the immune system due to a lack of vitamin D. Similar to the flu, these are also factors in how rapidly COVID-19 may spread.

Cold Chicago weather makes people stay indoors where it’s more difficult to socially distance. And as the pandemic continues, people are beginning to get complacent about meeting in large groups, which has increased the reach of the virus. The upcoming holidays, where people enjoy getting together with family and friends, may well exacerbate the problem.

Another issue is that cold air typically means dry air, and to be comfortable, people tend to turn up the heat which further dries out their homes. Why is this a concern? In cold temperatures our mucous membrane dries out, making it much harder for the nose to filter pathogens. When airways are dry, it allows the virus to have easier access to the body.

A study published in the journal Transboundary and Emerging Diseases found evidence of a potential way that cooler temperatures will affect COVID-19. Their results said that the number of COVID-19 cases increased as the air became drier and the humidity level dropped. “There is growing evidence that climatic factors could influence the evolution of the current COVID‐19 pandemic,” the authors stated. “Overall, a decrease in relative humidity of one per cent was associated with an increase in cases of seven to eight per cent.”

Temperature and relative humidity can affect coronavirus transmission as the virus can survive longer at lower temperatures, the authors said. The virus can also stay “suspended in the air” longer at lower humidity, they claimed.

For all of the reasons above, some experts predict a second wave of the COVID-19 pandemic during the coming fall and winter months. In other words, cooler temperatures will affect COVID-19 by causing it to spread more rapidly.

What Can You Do to Protect Yourself From the Effects of Cooler Temperatures on COVID-19? 

  • Get a seasonal flu shot because it’s possible to get COVID-19 and the flu at the same time
  • Get good sleep, don’t let your body get run down 
  • Stay hydrated
  • Eat healthily
  • Keep stress in check
  • Wash your hands regularly
  • Increase ventilation
  • Use a humidifier during cold months 
  • To help keep mucous membranes moist, regularly use a drug-free saline nasal spray
  • Wear a mask
  • Practice social distancing 

All of those things will probably have a much bigger impact on the virus than the actual temperature. In any case, adhering to them could help mitigate the negative ways that cooler temperatures will affect COVID-19 and its spread.
