Physical activity is associated with better immune function
There is significant health benefits that can be derived from regular physical activity on our heart, muscles, and even brain function.
Regular physical activity can help reduce feelings of stress, anxiety and depression. There is ample evidence that regular physical activity is also associated with a better immune function.
Importantly, these benefits are achievable for everyone regardless of current health status, underlying conditions, gender or age. And, those who are least healthy (and, consequently, at greatest risk for severe COVID-19 responses) have the most to gain from maintaining an active lifestyle.
Physical Activity Guidelines
Physical Activity Guidelines for Americans suggest all physical activity is beneficial regardless of intensity.
The Physical Activity Guidelines suggest Americans engage in 150 minutes of moderate intensity activity each week or 75 minutes of vigorous intensity each week.
Individuals are encouraged to limit their sitting time as much as possible. But, it is important to listen to your body. If you feel pain or stiffness from too much sitting and inactivity, get up and move around. Even walking breaks of 2 minutes are associated with benefits (reduced pain, improved alertness). Limiting prolonged sitting to less than 60 minutes would be a good rule of thumb.
Certainly those who can safely engage in moderate to vigorous intensity activity should do so. But if light physical activity is all you are able to achieve, there are health benefits that come from this. Essentially, some physical activity is good; more physical activity is better.
