What’s the difference between a regular sauna and a FIR one?

Traditional steam or regular sauna has a fully heated environment and is created by a heater that uses a rock mass and the use of water poured over the rocks to create steam. Traditional saunas
take approximately 45 minutes to pre-heat the interior of the room for use.

In an infrared sauna, the bather is being heated directly by the infrared heat source and the air temperature in the room is only a default of the infrared emitters. An infrared
sauna takes approximately 15 to 20 minutes for the emitters to come up to temperature.  (approximately 115 to 135 degrees F) When using the infrared, the bather waits until the
infrared emitters in the room are running at full heating potential.

With a traditional hot rock sauna, the sauna heating element (an incoloy rod) heats the surrounding
air (not the body directly), resulting in a very hot environment, with air temperatures in the 180F to 220F range. The body then reacts to this negative environment, and begins to sweat in an attempt to cool the skin and thus the body. The sauna user can adjust the humidity within the unit to protect the body’s mucous membranes (lungs, skin, eyes, etc.) by splashing water on the heating element. This is why traditional Finnish saunas are often understood to be filled with steam.

Infrared heat is a very soothing and gentle heat. Unlike traditional saunas which operate in excess of 180⁰ F making the experience unbearably hot and claustrophobic, infrared saunas have the benefit of being effective at a more comfortable operating temperature of between 120-150⁰ F.

Traditional saunas only heat the air in the cabin whereas Infrared saunas penetrate deep into your cells giving you a deep detoxifying sweat. Because infrared heat penetrates deep into tissues versus just the surface of skin, Infrared saunas are seven times more effective than traditional saunas for detoxifying the body. By raising the body’s core temperature, Infrared saunas can produce a sweat composed of 20% toxins compared to 3% with a traditional sauna.


As is known, heat application can be done in two ways: through contact (when bodies come into direct contact) and through heat dissipation (using infrared radiation).
According to the second law of thermodynamics, heat passes from the body with high temperature, low body temperature and warms it.
When later the body conveys the heat, moving Bbsth and comes into contact with the receiving body heat, a similar process occurs: the body transmits heat with higher temperature heat transfer body heat gain. This process is the basis for ordinary bathhouses and saunas, in which the body conveys the heat air or water vapor.



Saunas use infrared heat instead of hot rocks or steam used in traditional saunas.  Traditional saunas heat the air at extremely high temperatures which can make the experience unbearably hot and difficult to breathe. Because infrared heats the body directly instead of simply heating the air, infrared saunas are seven times more effective for detoxification.  In a Sunlighten sauna, you will experience the deepest, most detoxifying sweat of your life.
