Hot yoga promotes the detoxification of metabolic waste throughout the body. As with all of hot yoga's intermingled benefits, the enhanced circulation, cardiac output, and kidney function promoted by the excess heat can all serve to remove toxins from the body. Sweat, of course, is a big contributor to waste excretion, while stretching and breathing both function to remove metabolic 'junk' from muscles and joints, such as lactic acid, uric acid, and trace heavy metals.
Individuals should, of course, be sure to drink plenty of extra water before, during, and especially after a hot yoga session. Their bodies will be filtering these wastes for hours afterward. The stress reduction and detoxification process may be enhanced with herbal tea or certain essential oils as well, and some mineral supplementation may benefit. Individuals should consider coconut water for potassium and a small magnesium supplement after a sweaty session.
