Heat relieves pain by expanding blood vessels and increasing circulation. Better circulation allows more oxygen to reach injured areas of the body and helps reduce pain and speed up the healing process.
Perspiring is part of the complex thermoregulatory process of the body that increases the heart rate, cardiac output, and metabolic rate. The process requires a large amount of energy and reduces excess moisture, salt and subcutaneous fat. Fat becomes water-soluble and the body sweats out fats and toxins.
During a 10-20 minute sauna session, your heart rate increases by 50-75%. This provides the same metabolic result as physical exercise. The increased cardiac load is the equivalent to a brisk walk. There is a nominal effect on blood pressure because the heat also causes blood vessels in skin to expand to accommodate increased blood flow.
Toxins such as sodium, alcohol, nicotine, cholesterol and carcinogenic heavy metals accumulate in the body during modern daily life. The body eliminates most toxins naturally by sweating. Heat therapy stimulates the sweat glands that cleanse and detoxify the skin.
Heat therapy loosens the muscles and relaxes the body. Many massage therapists use heat to provide more thorough and effective treatment.
BENEFIT TO SKIN
Heat improves circulation, expels dirt & chemicals and removes dead cells on the surface of the skin. This leads to a softer and clearer complexion.
