This blog post is written by Ben Greenfield and Narrated by Brock Armstrong. I will be the first to admit that I spent most of my life not really understanding the difference between a “regular” sauna and an infrared sauna. While I’ve certainly covered wet saunas vs. dry saunas on a , and I’ve thoroughly discussed the myriad of benefits from heat exposure (from dry saunas to steam rooms to those dorky sauna suits) in ... ...until the recent show I’d never really delved into the concept of infrared saunas on the podcast either. But now that I’m spending at least two and, , as many as five days per week in an infrared sauna, I figured it was high time I filled you in on what I’m doing with infrared, why, and three ways to biohack your sauna for more heat, more sweat, and bigger benefits. ---------------------------------- Why You Should Use A Far Infrared Sauna First, you should know that this article isn’t really going to delve into the nitty-gritty of why heat therapy and saunas are beneficial, because . But before learning how to biohack your sauna experience, it is important for you to have a basic idea of what an infrared sauna is, and how it differs from dry saunas or steam rooms, especially if you haven’t jumped on the sauna bandwagon yet. Basically, an infrared sauna is a type of sauna that uses light to create heat. These saunas are sometimes also called far-infrared saunas, and the "far” simply describes where the infrared waves fall on the light spectrum. A traditional "dry sauna" uses heat from rocks or other heating elements to warm the air, which in turn warms your body. So a dry sauna must rely only on indirect means of heat: first, convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect. But because an infrared sauna instead relies upon light, it can heat your body directly without significantly warming the air around you, and the light waves from the infrared sauna penetrate deep (2-6 inches) into your body for a heating effect that allows more activation of your sweat glands compared to dry sauna. So an infrared sauna doesn't feel as hot as a dry sauna, but you sweat as much or more. In the book , Dr. Michael A. Schmidt explains the benefits of the slightly lower temperature of an infrared sauna like this: "Saunas are being used by some doctors to stimulate the release of toxins from the bodies of their patients. They have found that a lower temperature (105º-130ºF) sauna taken for a longer duration is most beneficial. These low temperatures stimulate a fat sweat, which eliminates toxins stored in fat, as opposed to the high temperature sauna, which encourages a water sweat.” Interestingly, the far infrared rays you get in an infrared sauna consist of similar wavelengths that are emitted naturally by the human body (yes, ). This is one potential explanation of why many people feel so energetically rejuvenated and balanced from contact with far infrared waves in an infrared sauna compared to feeling "drained and dehydrated" after a dry sauna experience. Tests have shown that the energy output in an infrared sauna is tuned so closely to your body’s own infrared radiation that you . So how does a far infrared sauna actually generate heat and invisible light? Far infrared saunas typically use either a carbon or ceramic heater, which do not turn red hot like the heating elements inside a conventional dry sauna, but instead produce invisible, far infrared heat. This is the same type of heat as produced by the sun, but without any of the effects of solar radiation. For years, many folks in the alternative health community have sworn by using infrared heat lamps as a source of far infrared heat, but these lamps can be cumbersome, they can get extremely hot to the touch and they  can be difficult to maintain at a constant temperature compared to an infrared sauna. So basically, an infrared sauna is like having a tiny little temperature-controlled sunshine
