BENEFITS OF HOT TUBS


Why do you immediately feel good when you get into a hot tub? For a start, you instantly lose 90% of your body weight, reducing the load on your heart by 10-20%. And, because the temperature is sustained at around 38?C, the feeling of well-being that you experience is accompanied by changes in your circulatory system that have a beneficial effect on many aspects of your body. When this is combined with the therapeutic affect of the spa's massage jets, which further relax the muscles, and promote healing, the result is sheer bliss!

What happens to your body in the hot tub? The body's first reaction to being immersed in hot water is to try to get back to its normal temperature by working the heart harder to pump the blood to the surface where it hopes to be cooled. This causes a temporary increase in blood pressure. Of course, because the water is hot the blood is warmed not cooled. The result is that the core body temperature rises and, after a short while, the warm blood causes the blood vessels to dilate which lessens the resistance to blood flow and reduces blood pressure. The body begins to perspire, expelling toxins and the muscles relax, temporarily relieving aches and pains.
