Just like a healthy diet, exercise can contribute to general good health and hence to a healthy immune system.

It may contribute even more directly by promoting good circulation, which allows the cells and substances of the immune system to move through the body freely and do their job efficiently.

A 2020 study published in the ‘Journal of Sport and Health Science’ has found that ageing, obesity, and inactivity can have negative effects on the immune system.

Ageing leads to negative changes in innate and adaptive immunity and obesity causes systemic inflammation and adversely impacts immune function and host defence.

The study says that regular moderate-intensity physical activity reduces obesity and helps in bolstering your immune defence.

It does so by improving the immune system’s surveillance activity (when immune cells in the bloodstream look for infection) against pathogens and reduces morbidity from viral infections and acute respiratory illness.

Experts recommend moderate-intensity physical activity typically ranging between 150 and 300 minutes per week. Don’t overdo things though, because overtraining is as bad as physical inactivity, and exercising while infected is risky.
