Health benefits of soaking in a hot tub

Apart from the luxurious experience you can get from having a tub, there are also numerous health benefits. Here are some ways on which soaking in a hot tub can be beneficial for your well-being:

It lessens migraine attack

At times, tension causes headaches; and soaking in the hot tub relaxes your muscles. Your pain recedes and reduces the possibility of a migraine developing. Also, if you have sinusitis, a dip in bath with its warm steamy air can relieve congestion and any sinus headache that comes with it.

It helps relieve stress

Stress can cause headaches, sore muscles, and fatigue. Soaking in a hot tub has a therapeutic effect that relaxes the muscles and joints, improves blood circulation, and lifts your mood.

It helps improve the conditions of people with diabetes and high blood pressure

A study published in The New England Journal of Medicine suggested that spending time in the hot tub decreases blood sugar levels and reduces blood pressure.

The hot temperature’s effect is the same as that of physical exercise which is beneficial to diabetics. The temperature improves blood circulation resulting to a lower blood pressure.

It helps you achieve healthier skin

As we all know, stress can cause premature aging. A regular dip in a hot tub increases blood circulation, which means your skin receives ample nourishment and moisture. As such, your skin glows; you look healthy and young for your age.

It helps soothe pain

A study published in the British Journal of Rheumatology stated that a regular spa therapy helped diminish lower back pain.

Another study revealed that recovery from knee replacement surgery was faster as compared to non-soakers. Patients in both studies showed improvement in their flexibility and became less dependent on pain relievers and anti-inflammatory drugs.

Furthermore, arthritic patients regained their muscle strength after regular sessions in a hot tub. The water’s buoyancy helped them move their joints, enabling them to do simple tasks.

It helps improve sleep disorders

A scientific study showed that a dip in a hot tub before bedtime helps achieve a good night’s sleep. Insomniacs could gradually relax enough to get to sleep.


Indeed, there is more to soaking in a hot tub than mere relaxation. By doing so, you can achieve mental alertness, physical strength, flexibility, and tranquility.
