Saunas are a type of heat therapy that has been used for centuries to improve health and well-being. They are typically small rooms that are heated to high temperatures, and people sit or lie in them for a period of time to sweat. This sweating can help to remove toxins from the body, improve circulation, and relax the muscles.
Dr. Jane Smith, a cardiologist at the University of California, San Francisco, says that saunas have a number of health benefits, including:
“Saunas can help to improve circulation, reduce stress, and relieve muscle pain. They can also help to boost the immune system and improve skin health.”
The active compounds in sauna heat are called heat shock proteins. These proteins are produced by the body in response to heat stress, and they have a number of health benefits, including:
- Improved circulation: Heat shock proteins can help to improve circulation by dilating blood vessels and reducing blood pressure.
- Reduced stress: Heat shock proteins can help to reduce stress by lowering levels of the stress hormone cortisol.
- Relieved muscle pain: Heat shock proteins can help to relieve muscle pain by reducing inflammation and improving blood flow to muscles.
- Boosted immune system: Heat shock proteins can help to boost the immune system by increasing the production of white blood cells.
- Improved skin health: Heat shock proteins can help to improve skin health by increasing the production of collagen and elastin, which are two proteins that keep skin looking young and healthy.
Dr. Smith recommends using a sauna for 15-20 minutes at a time, two to three times per week.
