Question

how can participation in physical activity lead to improved sleep patterns?

Physical activity can increase body - temperature temporarily. After activity, the drop in body - temperature signals sleep. It also reduces stress and anxiety, which are sleep - disruptors, and can promote the release of endorphins and other neurotransmitters that aid sleep.

Participation in physical activity can lead to improved sleep patterns through mechanisms such as body - temperature regulation, stress and anxiety reduction, and neurotransmitter release.
