Scientists have found a simple way to reduce the risk of infection and death from coronavirus Previous research shows that physical activity can reduce the risk of infection and the severity of respiratory infections due to the ability to strengthen the immune system. The link between regular physical activity and COVID-19 severity is poorly understood but likely involves both metabolic and environmental factors, researchers say.

Scientists in the course of their work tried to identify the time of physical activity needed to reduce the risk of infection.. Researchers searched three major databases for relevant studies published between November 2019 and March 2022 and combined the results.

A total of 1,853,610 adults took part in the studies. The average age of the participants was 53 years. Most of the studies were observational and were conducted in South Korea, England, Iran, Canada, Great Britain, Spain, Brazil, Palestine, South Africa and Sweden..

An analysis of the pooled data showed that overall, those who included regular physical activity in their daily routine had at least an 11% lower risk of contracting SARS-CoV-2..
