Key Takeaways
Researchers found people who exercise regularly have an 11% lower risk of contracting COVID-19 than those who don’t.Regular exercisers also have a lowered risk of severe COVID and hospitalization from the virus.Experts say more research is needed to explore the association.
New research has linked regular exercise with a lowered risk of getting COVID-19. And those who exercise regularly whodohappen to get COVID-19 are less likely to develop a severe form of the disease.
That’s the major takeaway from a scientific review published in theBritish Journal of Sports Medicine.For the review, researchers analyzed data from 16 studies of 1.8 million people to look for links between physical activity and how well a person fared with COVID-19.
The researchers discovered that people who were physically active were about 11% less likely to get infected with the virus compared to their less active counterparts. When they did get infected, more active people were also about 36% less likely to be hospitalized and 43% less likely to die compared to their more sedentary counterparts.

Why Might Exercise Lower Your Risk of COVID?
It’s important to point out that, while the study showed a statistically-significant lowered risk of contracting COVID-19 if you exercise regularly, it wasn’t a massive difference—just 11%. However, the study did find that exercising regularly seemed to lower the risk of complications from the virus.
Amesh A. Adalja, MD, an infectious disease expert and senior scholar at the Johns Hopkins Center for Health Security who was not involved with the study, told Verywell that the findings aren’t surprising.
“Physical activity is part of being healthy and there are cascading impacts on the immune system that accrue when people are physically active,” he said.
In fact, an improved immune response is exactly what Ezzatvar credits.
“There is evidence that regular physical activity might contribute to a more effective immune response, providing enhanced protective immunity to infections, which could explain the relationship between exercise consistency with COVID-19 infection,” she said.
According toThomas Russo, MD, professor and chief of infectious disease at the University at Buffalo, there could also be indirect links between exercise and COVID protection.
“It could be that exercise lowers your risk of obesity, a condition that puts you at increased risk of severe disease,” Russo told Verywell. “It could also be that people who exercise are more health-conscious than couch potatoes and take less health risks that put them at risk for getting COVID-19.”

Ultimately, Ezzatvar said the findings should encourage people to try to be physically active.
“Everybody can benefit from being more active, regardless of age, sex, or physical ability,” she said. “In contrast to the vast majority of drugs, exercise is free of adverse effects. It’s time to consider exercise as medicine. It’s never too late to start being physically active.”
