Improved mental health: Exercise has been shown to improve mood, reduce symptoms of anxiety and depression, and improve cognitive function. This is thought to be due to the release of endorphins during exercise, as well as its ability to reduce inflammation and improve blood flow to the brain. For example, a study published in the journal Frontiers in Psychology found that exercise was effective in reducing symptoms of depression in adults (7). Similarly, a study published in the journal Neurology found that regular exercise was associated with better cognitive function in older adults (8).
Improved sleep: Regular exercise has been shown to improve the quality and duration of sleep, which can further improve overall health and well- being. For example, a study published in the journal Sleep found that moderate-intensity exercise was associated with better sleep quality and longer sleep duration in middle-aged and older adults (9).
Overall, these studies suggest that regular exercise can provide numerous health benefits. However, it's important to note that the type, intensity, and duration of exercise can all play a role in determining its effects on health. Additionally, individuals should consult with a healthcare professional before starting an exercise program, especially if they have any underlying health conditions.
