While being fit won’t prevent you from catching the virus, it does have many other protective effects. Physical activity releases endorphins, chemicals in your brain that revitalize your mind and body, and it can help to improve all aspects of your health. In addition to boosting your mood and improving you sleep exercise can also strengthen your immune system, something that is particularly important at this time, especially for older adults who are more vulnerable to COVID-19.
But don’t overdo it. While moderate physical activity supports immune function, too much intense activity—especially if you are not used to it—may have the opposite effect and suppress your immune system.
If you use exercise to keep up your energy and spirits in trying times such as these, you might be less inclined to turn to unhealthy coping mechanisms, such as drinking too much, which can also wear down your immune system.
