Thermal Effects: Both warm and cold baths can help lessen pain and discomfort while improving the healing process. Warm baths open up surface tissues which lead to increased blood flow and circulation which helps your tissues heal, oxygenate and purge toxins. Warm water slows down your internal organs and reduces aches and pains. Heat also increases the production of beneficial body hormones and stimulates the immune system. Warm, moist air can open up  congested or constricted airways in your lungs, throat and sinuses. Cold water therapy is effective for sprains and swelling and other issues.
Mechanical Effects: The massaging effect of the air bubbles creates beneficial chemical reactions in your skin and tissues which leads to increased circulation, oxygenating tissues and expelling toxins. Water decreases your body weight by 90% so it relieves physical stress from your joints and bones, helping to relieve pain and discomfort. This floating effect helps relax the body, because muscles don’t have to work as hard and are given a chance to relax.
