Think about it. There are lots of reasons to exercise – reduced risk of cancer and diabetes, lower cholesterol, greater resistance to bacteria and viruses, improved quality of sleep and longer life for starters.
Science leaves little doubt that exercise is one of the most important things for your body and the benefits of human immersion into a vessel of warm water have been known and understood for centuries. In modern terms, its greater-than-atmospheric pressure stimulates greater cardiac output and a slower pulse, while the warm temperatures dilate blood vessels to boost circulation and encourage the body to release mood-improving hormones. Increased circulation further speeds the flow of nutrients to help heal and regenerate cells and flush away pain-causing chemicals. Under the pressure of hydrotherapy, warm water loosens tight muscles, stimulates the immune system, invigorates the circulation and digestive systems and reduces pain sensitivity.
