Getting a Good Night's Sleep Warm water massage stimulates the body to release endorphins that reduce stress naturally. In addition to stress reduction, a hot tub’s hydrotherapy jets also dilate blood vessels to help prevent headaches. Also, when it comes to falling asleep faster and getting a good night's sleep, the National Sleep Foundation clearly stated, "soaking in hot water, such as a hot tub or bath, before retiring to bed can ease the transition into a deeper sleep." |
