Studies have found that exercise in warm water can help alleviate pain and reduce the amount of medication needed to treat pain for those with rheumatoid arthritis, fibromyalgia, ankylosing spondilitis and osteoarthritis.
According to The Arthritis Foundation, warm water exercise can help to “keep joints moving, restore and preserve flexibility and strength” which “protects joints against further damage.” Also, “it improves your coordination, endurance and your ability to perform daily tasks (such as walking or writing).”

According to a study in The New England Journal of Medicine, diabetic patients who received hot tub therapy reduced their blood sugar levels, lost weight and improved their sleep patterns.

When immersed in warm water, the blood vessels dialate (vasodialation), lowering blood pressure and allowing the heart to pump blood more easily. This not only strengthens your heart, but also boosts your immune system and improves digestion.

Hot tub therapy provides a warm and relaxing environment which naturally enhances mood, reduces stress, improves the ability to focus, alleviates mental anxiety and promotes a strong sense of well being.

Studies show that a 15-minute soak in a hot tub 90 minutes before bed can help improve sleep. Warm water raises body temperature, and the drop in temperature that occurs after leaving a hot tub may help induce sleep.

For those who have difficulty performing weight-bearing exercises on land, the added buoyancy provided when immersed in water can relieve pressure from joints and make exercising easier. Hydrotherapy can also provide relief from chronic pain such as fibromyalgia and chronic fatigue syndrome.

Massaging jets relax muscles that are fatigued or injured, and relieve tension on joints and nerves, while warm water raises body temperature and expands the blood vessels, delivering more blood to your muscles and shortening recovery times while providing relief from pain and soreness.
