Sleep is normally preceded by a drop in body temperature. If that’s true, how could a hot tub help?
First, soaking in a hot tub helps you relax mentally while the water’s buoyancy helps decompress your joints. Your circulation increases while your blood pressure and heart rate decreases, helping you reach a resting state. In the hot tub, your body temperature rises. Yes, rises.
What happens after that relaxing soak also helps you maintain the sense of calm and relaxation that naturally helps you fall asleep. But now, your core body temperature begins to drop as you cool down, signaling to your body that it’s time to sleep.
Whatever the science, soaking before bedtime seems to be a universal remedy for helping people sleep.
Lack of sleep can leave you feeling nervous, groggy and depressed or cause erratic mood swings. Because sleep researchers believe that insomnia can be traced to hectic, stressful lifestyles, relaxing in a spa regularly can help.
By taking a 15-minute soak in a hot tub about 90 minutes before attempting to sleep, your body temperature can drop to enable a better night’s sleep naturally without the grogginess sometimes caused by prescription remedies.
