Regular exercise has numerous mental health benefits. Physical activity has been shown to reduce symptoms of anxiety and depression by increasing the production of endorphins, which are natural mood lifters. Additionally, exercise can help improve self-esteem and cognitive function, as well as reduce stress and improve sleep quality.

For example, a study published in the Journal of Psychiatric Research found that individuals who engaged in regular physical activity had significantly lower levels of anxiety and depression compared to those who were less active. Furthermore, the American Psychological Association has reported that exercise can lead to improvements in self-esteem and cognitive function, particularly in older adults.
