Sweating It Out
By Dr. Wilson
• The sweating process helps eliminate toxic chemicals and heavy metals from the body, relieving a burden on the kidneys and liver, says Larry Wilson, M.D., a holistic physician and author of Sauna Therapy. In fact, saunas have been used in drug and alcohol rehabilitation centers to rid patients' bodies of addictive toxins stored in fatty tissue.
• The heat causes blood vessels near the skin to expand and become more flexible, improving circulation in those areas. To further improve circulation, Finnish sauna users traditionally have tapped short bundles of birch branches, called "vihtas" or "vahtas," against their skin; modern sauna users can achieve a similar result with body brushes.
• Skin complexion improves with sauna use, as the heat naturally opens pores and sweats out impurities.
• Saunas may also promote healing by inducing the body's release of natural painkillers; improved circulation then helps carry those painkillers swiftly to areas of the body needing them most.
• Some studies have linked regular sauna use to a lower risk of colds. While researchers have not yet confirmed this, some believe that the inhaled hot air kills viruses that cause the common cold. Steam saunas have their own benefits, including the ability to relieve symptoms related to upper respiratory infections or colds as users inhale the steamy air.
• Raising the body's temperature helps the immune system kill bacteria, parasites and viruses, adds Dr. Wilson.
However, pregnant women and children under 5 should avoid using saunas. Others should always check with their doctor before beginning a sauna therapy program.
