Infrared is the band of light you perceive as heat. You can’t see infrared with the naked eye, but you can feel this type of light in the form of heat. The sun produces most of its energy output in the infrared segment of the light spectrum. Infrared rays heat your body without having to heat the air around you.
Your body expends energy (calories) to produce sweat - 1 gram of sweat requires approximately 0.586 calories. A moderately-conditioned person can easily sweat of 1000 grams or more in one Infrared Sauna session. That’s the equivalent to running 6-9 miles! While this weight loss can be regained by rehydration with water, the calories expended in the process will not come back. Sweating also allows the body to release built up toxins naturally, keeping your body cleansed even when not on a cleansing program.
Because infrared is part of natural sunlight, Infrared Saunas are completely safe! Health professionals have used infrared heat lamps for decades to treat muscle and joint problems. In hospital baby care units, incubators are often equipped with infrared heating systems to keep newborn babies warm.
Whereas conventional saunas transfer heat by circulating hot air to warm your body from your head down, infrared saunas warm your body directly. This allows an in-depth heat in a more pleasant temperature, thus providing more health benefits and a highly enjoyable and comfortable environment.
