Sweating is great for cleansing the body of toxins and harmful substances that have built up under the skin. Perspiration can flush the body of substances such as alcohol, nicotine, cholesterol, salt, and heavy metals such as lead, mercury, nickel, and cadmium. Infrared saunas detoxify the body by promoting the body’s ability to perspire by increasing blood circulation.
Sweating in the sauna allows the body to purge toxins and inorganic materials at a much quicker rate than it would normally, leading to a smoother transition period. Sweating also boosts “feel-good” endorphins and as the detox process begins, the body can begin to heal itself.
One reason infrared saunas have become so popular is the fact that they aid in the strengthening of your immune system. The heat inside the sauna raises your core body temperature by 1°-2°C.
This is like having an artificial fever, and all the cells in your body react accordingly. This boost is the result of the body being subjected to such a high heat that it causes a rise in core body temperature.
Studies and individuals have reported/shown that near infrared light stimulates white blood cell production, promotes cell regeneration, restores enzyme activity, and reduces cell death.
This helps your body repair cells and tissues that were damaged by heavy metals and toxins.
Weight loss is one of the primary benefits cited by many people who use or sell far infrared saunas. Unfortunately, there is little evidence to back up any weight loss or calorie-burning claims.
Many have reported the cardiovascular benefits of using an infrared sauna. Another key factor regarding the use of far infrared saunas to lose weight is the confusion between water loss and fat loss. Sweating causes water loss, so it is no surprise that people often weigh a little less after a sauna session. But any weight loss experienced from water loss is likely to be regained.
Weight loss has been reported to occur when one is using a far infrared sauna. Due to excessive sweating, water weight can be lost, thus causing some weight reduction. While water loss is temporary and does reduce weight, it is not permanent or sustainable weight loss.
