Exercise and Immunity
Exercise and Immunity
The way we eat isn’t the only way we can support our immune systems. Exercise, among other lifestyle factors, has a significant effect on immune health. While we don’t know exactly why, there are a few theories that support the strong connection between regular physical activity and immune health.
The CDC recommends doing moderate-to-vigorous exercise for at least 150 minutes per week, including at least two strength training sessions that work all major muscle groups. If we exercise beyond this goal, we receive more health benefits. Here are some tips on how to hydrate appropriately before and after exercise and how to stay active during the winter season.
Engaging in the recommended amount of exercise has been shown to have benefits on markers of immune function. Full-body exercise including cardiovascular activity mobilizes immune cells, making them better able to perform immune functions like attacking any foreign pathogens such as bacteria and viruses that may enter our bodies. Exercise also affects the release of stress hormones; lower levels of stress hormones may benefit immunity.
While we know that exercise can impact immune health, researchers are still studying the potential mechanisms behind the relationship. Exercise cannot prevent us from getting sick, but it is a key element in improving our health. By practicing healthy lifestyle habits like a regular exercise routine, our bodies are better equipped to fight potential intruders, cope with symptoms of illness and support illness recovery.
