It's not a secret that a hot tub can be a benefit to your health. Soaking in a tub of hot water has been shown to loosen stiff, aching joints allowing them to move easier. People with arthritis, multiple sclerosis and other conditions involving deteriorating range of motion are able to keep themselves more mobile by decreasing tension in muscles. Warm water increases circulation to aching joints, helping to remove inflammation and the buoyancy of water helps to relax muscles. Hydrotherapy also helps alleviate back pain by reducing stress and stiffness. The US National Institute of Health claims that 4 out of 5 Americans suffer chronic back pain. Steam from the water surface can open nasal and bronchial passages allowing greater intake of oxygen to your blood stream.

Studies show that 70 percent of Americans with jobs suffer some form of stress related condition including anxiety and insomnia. Immersing yourself in hot water help your whole body relax while raising your body temperature which increases your ability to fall sleep according to the National Sleep Foundation.
 

Many people don't realize the fitness benefits one can enjoy from a hot tub. A recent study at the Mayo Clinic found that soaking in a hot bath gives many of the many health benefits of exercise with less strain on the heart. Hot water increases your heart rate while lowering blood pressure, instead of raising it as most exercise does.
