No matter your age, getting those muscles and bones up and out can really do wonders for your sleep routine. It's one of the most natural sleeping pills I know.
Take a look at children, for instance. After an afternoon of play, they're ready for sleep at bedtime. Same with adults after gardening, a game of basketball, a walk on the beach, skiiing. Going with the flow of movement engages the mind, body and many times the spirit—the troika of wellbeing. It's no wonder a good night's sleep can follow.
