Though saunas have been around since time immemorial, their latest version, infrared saunas, are relatively new. The technology was developed around the 1960s when scientists sought a more efficient method to heat a sauna. Traditional saunas, which use heated rocks to warm a space, generate steam and too much heat, which can be detrimental to people’s sauna enjoyment, not to mention their health.
Infrared saunas on the other hand, use infrared rays (the same natural rays of the sun but only without the harmful UV rays) to raise the body’s temperature. Infrared saunas don’t emit steam, and they don’t get as hot as traditional saunas do, but they are just effective as traditional saunas in making you sweat. And according to many owners, even better.http://www.jnhlifestyles.com/blog/far-or-near-infraredwhats-the-best-infrared-sauna-to-buy-for-a-home/
