Infrared saunas differ from traditional saunas in that, rather than heating the body through the use of steam, they use infrared heaters which emit heat that can be absorbed by the body. An infrared sauna is usually a small portable unit, which can be set up and used wherever it is required and this makes it more affordable than a traditional sauna. The infrared heaters produce radiant heat similar to that produced by the sun. However the benefit of an infrared heater is that it does not produce ultraviolet rays, which can be harmful. Manufacturers of the units and others claim that there are a number of health benefits in using the sauna and this includes detoxification of the body and better circulation as a result of the increased sweating. Relaxing in the sauna is also said to be good for relieving stress and also for helping to reduce the pain of sore muscles and stiff joints. Generally, time in the sauna should be limited to no more than 30 minutes at a time and as long as you use the unit properly on a regular basis, an infrared sauna therapy should prove to be beneficial to your health.
