Taking ice baths can promote better sleep by activating the body’s relaxation response. The cold exposure triggers a drop in core body temperature, which helps signal to the brain that it's time to wind down. After exiting the bath, the body warms up, naturally promoting a sense of drowsiness and relaxation. This cooling process can also help regulate the circadian rhythm, making it easier to fall asleep and stay asleep. For those struggling with restless nights, incorporating ice baths into a bedtime routine may enhance sleep quality by fostering a deeper sense of calm and physical recovery.
