Sitting in a sauna for a period of time will lead to sweating, which has many health benefits. Infrared saunas, specifically, are used for weight loss and relaxation. Infrared, a type of light, is used to heat objects in the sauna instead of air. One?s respiratory system is not exposed to high heat as in conventional sauna. It saves lots of time as well. These saunas, based on infrared technology, are more effective as heat reaches deeper in the skin unlike conventional saunas. Deep heat penetration allows removal of toxins, alcohol, nicotine and metals. It helps in curing chronic fatigue; promotes muscle growth; raises growth hormones level; and reduces cellulite. Calories used in half an hour in an infrared sauna session are more than that used while running for the same time. Infrared Saunas, which often have a maximum capacity of four, can be installed anywhere in the house. Portable infrared saunas are also available. Electric light infrared saunas are very helpful for cancer patients. They raise oxygenation and remove radio active residues. Infrared saunas are good for chronic infections. Infrared saunas require 90% less energy and heats much faster than traditional saunas. This sauna can also be used for patients suffering from varicose veins, metal implants, hypertension and diabetes where conventional saunas do not help.
