An infrared sauna is a type of sauna that uses light to create heat.
These saunas are sometimes called far-infrared saunas — "far" describes where the infrared waves fall on the light spectrum. A traditional sauna uses heat to warm the air, which in turn warms your body. An infrared sauna heats your body directly without warming the air around you.
The appeal of saunas in general is that they cause reactions, such as vigorous sweating and increased heart rate, similar to those elicited by moderate exercise. An infrared sauna produces these results at lower temperatures than does a regular sauna, which makes it accessible to people who can't tolerate the heat of a conventional sauna.(http://www.mayoclinic.org/healthy-living/consumer-...)
6 Benefits of Infrared Sauna Therapy
Sweating is one of the body’s most natural ways to eliminate toxins, making it a crucial part of detoxification. When compared to traditional Swedish saunas, infrared saunas allow you to eliminate about seven times more toxins.
Infrared sauna therapy promotes relaxation by helping to balance your body’s level of cortisol, your body’s primary stress hormone. The heat generated by the sauna will also help to relax muscles and relieve tension throughout the body, allowing you to relax and de-stress.
3. Pain Relief
If you suffer from muscle aches or joint pain, infrared saunas can relieve this form of inflammation by increasing circulation and relaxing your muscles.
4. Weight Loss
The heat generated by an infrared sauna will cause your core temperature to increase, which can also lead to an increased heart rate — the same increase in heart rate that you experience when exercising. When your body has to work harder to lower your core temperature or keep up with an increased heart rate, your body will burn more calories, resulting in weight loss. An article, titled Effect of Sweating, in the Journal of the American Medical Association concluded that a 30-minute infrared sauna session could burn roughly 600 calories.
5. Improved Circulation
As the heat from infrared saunas increases your core body temperature, your circulation will increase along with it. Consistent infrared sauna sessions, especially in the middle-infrared level, can stimulate blood flow, improve muscle recovery, and decrease pain and inflammation after intense exercise.6.
