Sauna use has been shown to support deeper, more restful sleep by promoting relaxation, lowering cortisol levels, and increasing melatonin production. The gentle heat helps activate the parasympathetic nervous system—your body’s rest-and-digest mode—while boosting circulation and reducing muscle tension. Studies suggest that the drop in core body temperature after a sauna session mimics the natural decline that occurs before sleep, helping you fall asleep faster and stay asleep longer. | Sun Hom
