Regular physical activity is a vital component of a healthy lifestyle that directly contributes to achieving a good night’s sleep.1

While the exact physiological mechanisms linking the two are multifaceted, the relationship is mutually beneficial. Engaging in regular exercise helps promote better sleep quality, which in turn supports the body’s essential restorative processes. During deep stages of sleep, the body utilizes the time to repair microscopic tissue damage caused by physical exertion, releases growth hormones to facilitate muscle regeneration, and replenishes energy stores in the muscles for future demands.12

By incorporating at least 150 minutes of moderate-intensity physical activity into your weekly routine, you can improve your overall health, manage daily physical and emotional challenges more effectively, and foster the restorative rest necessary for optimal physical and mental function.12
