Research clearly shows that physical exercise can reduce stress and anxiety, but it’s less clear how this occurs. Multiple mechanisms are likely to be important. Exercise can help to reduce the body’s response to stress by boosting serotonin levels in the brain.
It can also give us a sense of achievement and increase our self-esteem, which can provide psychological routes by which to reduce stress. Finally, research shows that exercise taken in moderate amounts and at appropriate times of the day can improve our sleep. Good sleep quality can help us to regulate our emotions and therefore provides another way in which physical exercise helps to reduce stress.
