Over the past 10 years, the growth in Far-infrared saunas has sparked debate over the end of so-called traditional saunas. Both traditional hot rocks sauna and the Far-infrared saunas can help promote relaxation and stress reduction, through sweating and detoxification which relieves aches and pains. Both sauna types (traditional vs. infrared) provide these benefits, although the conditions under which the benefits are achieved are quite different.
"The main differences between traditional saunas and infrared saunas are temperature, method of heat, heat-up time, and the amount of energy used for a typical sized room.

The temperature for a traditional sauna typically ranges between 150 and 185° F. The temperature for a far-infrared sauna is usually set bet1A1een 120 and 140° F; however, unlike the traditional sauna, the goal in Infrared saunas is not to achieve a high temperature. Instead, in a far-infrared sauna, the user wants the emitters to remain active because infrared energy is only being emitted (therefore providing the benefit of the deep penetrating infrared heat) when the emitters are on. Because of this, the temperature difference is almost irrelevant, since profuse sweating results in both sauna types, but the method of heating the body is different. In an IR sauna the bather will feel hot and will sweat profusely, but at much lower temperatures. Thus, if the goal is to spend longer periods of time in the sauna, the IR sauna is a good choice.

In a traditional sauna, perspiration is achieved when the user enters a heated room. When a traditional sauna has been properly heated, the sauna walls are warm, the air temperature has achieved set temperature and the rocks are super-heated. When the high temperature is achieved, the elements cycle on and off to maintain the high temperature. Most traditional sauna users enjoy pouring water over the rocks to create steam to raise sauna humidity levels. TI1e benefits of pouring water over the rocks include: making the room more comfortable, moistening the nasal passages, and allowing the use of aromatherapy by mixing essential oils, with the water."

In a far-infrared sauna, the heat waves penetrate the body to effectively heat the body and raise the body core temperature to achieve this increased temperature, Far-infrared emitters create infrared energy which is close to the same wavelength as that which the body naturally emits often referred to as the ""Vital Range"" of 5 to 14 microns), so the energy is well received by the body .The infrared energy deeply penetrates the skin and warms the muscles and joints. When the energy enters the body, it causes the body temperature to increase and ultimately results in perspiration. In an infrared sauna it's important for the emitters/heaters to remain on almost constantly. Since there is no mass of rocks to retain    heat, the sauna will cool if the emitters shut off. Thus, even though most of the energy is turned into efficient infrared energy, IR saunas are designed for almost continuous operation of the infrared emitters."

"The heating time for the two rooms can be very different, depending on how the rooms are used. For a traditional sauna, a user should allow 30-40 minutes for the room to achieve a desired temperature and to properly pre-heat the rocks. The insulated walls and the heated rocks will keep the room hot and at stable temperatures. Many sauna users enjoy staying in the sauna after the elements have timed out (a 60 minute timer is standard" On all residential saunas).

"In a FAR-Infrared sauna, a person may begin using it when the sauna is turned on, since the infrared energy is being emitted by the heaters; however, many bathers would prefer to wait until the sauna is 110°F or hotter which can take between 5-15 minutes."

"The length of recommended use for each sauna type is approximately the same (10-15 minutes per session); however, due to the lower air temperatures and the ability to feel the effects of infrared heat faster than a traditional sauna,itis not uncommon for a person to spend a total of 20-   30 minutes in an infrared sauna."
