Hot Tub Health Benefits: As Good As Exercise?

Did you know that you can achieve similar results from using a hot tub as going for a run or cycling? Throughout human history, many cultures around the world have used heat therapy to improve health. It is only recently that science has begun to examine and understand the benefits of passive heating as opposed to getting hot and sweaty from exercise. There have now been many studies* on the effects of hot baths or warm water immersion in 40°C water, like a hot tub, versus cycling, running, and other forms of exercise.

Internationally renowned UK-based sports specialist institution, Loughborough University, claims that soaking in a hot bath and relaxing may be as beneficial for your health as a 30-minute walk.

Scientific evidence of hot tub health benefits includes increased blood circulation, better cardiovascular health and more.

Scientific Evidence of Hot Tub Health Benefits

The combination of multiple studies and research findings indicates that passive heating, such as using a hot tub, can offer health benefits comparable to that of low to moderate intensity physical exercises, such as walking, jogging, and cycling.

Improvements and health benefits include:
- Cardiovascular health & function (general fitness and reducing the risk of cardiovascular disease)
- Increased blood circulation
- Lower blood pressure
- Improved blood sugar control
- Reduced chronic inflammation (present with long-term diseases, such as type 2 diabetes)

How Does It Work?

When body temperature rises it finds a way to lose heat to regulate itself. The main way it does this is by widening the arteries and increasing the blood flow to the skin. Elevation in blood flow promotes the production of a variety of molecules in the blood that help with cell growth, repair and protection of blood vessels. Using a hot tub also has the benefit of hydrostatic pressure (the pressure of the water on your body), which assists in the return of blood to the heart.

Using a hot tub for health benefits can be as good as physical exercise.

When To Use a Hot Tub Instead of Exercise?

If you are physically able, exercise should not be substituted and using a hot tub should complement physical exercise. With busy lives and busy schedules, it isn’t always possible to allocate time for physical exercise or find the motivation so time in the hot tub is a great way to give you a quick boost.

For anyone who is physically unable to perform exercise or displays poor exercise adherence, using a hot tub now has proven health benefits. This is particularly true of anyone with disabilities and the elderly and this is where the benefits of using a hot tub are particularly significant.
