Exercise has many health benefits and these go beyond the strictly physical ones. A study looking at anxiety disorders and perceptions, found that exercise positively impacted the participants. Their perceptions to what previously was perceived as a threatening situation, was normalized after exercise. This study provides a helpful basis for working with anxiety disorders. Other studies have shown that exercise has a positive effect on stress and anxiety in general. So if you need to release some tension or are worried about something, get out and get moving!
