Sweating in a sauna causes your blood to flow to the important organs in your body, while sweating out toxins and impurities. Some toxins that should be removed through sauna sessions are heavy metals, nicotine, and certain industrial compounds (like phthalates).
Improving the Immune System
As you sit in a sauna, your core temperature increases, and your body produces white blood cells to compensate the “mini fever”. With regular use, your white blood cell count can increase, meaning your body can fight illnesses faster.
The increased heat of a sauna increases the body’s circulation, which delivers more oxygen and nutrients to the muscles and cells in your body. The increased oxygen can help relieve tired and strained muscles.
Use of a sauna reduces the body’s level of cortisol (the primary stress hormone). Regular use can relieve anxiety problems and sleep related issues, such as insomnia, which is often triggered by elevated levels of stress hormones.
