The far infrared sauna has a dry, warming heat which penetrates the tissues several inches deep.
A number of infrared sauna maunfacturers make sauna kits for personal home use.
Far infrared energy heats the body while allowing the surrounding air to remain cooler than in other types of saunas.
In an infrared sauna one begins to sweat rather quickly, without the discomfort of the higher heat in other types of saunas.
It's important to follow the manufacturer instructions which accompany your home kit, for safety reasons.
And just as with any hot treatments, including hot-tubs or steam baths, it's important to re-hydrate and replenish minerals after each use.
Drinking mineral water after a sauna is a good practice.
Traditional saunas are wood or gas fired, or electrically heated. Preheating a traditional sauna to 150-200 F degrees is required for "beneficial sweating". This intense heat is difficult for many to tolerate, and can be dangerously hot, especially when someone is ill.
The infrared energy is demonstrated to induce more cleansing than traditional saunas. The deeper penetration of the infrared energy allows the cells to eliminate toxins more efficiently and quickly.
Just as with any dry heat, steam bath or hot tub treatment, follow manufacturers' instructions and avoid intense treatments when you are ill, as the toxin release can be dangerous to a weakened immune system.
