Safety of Infrared Radiant Energy

Is the Far Infrared sauna safe for me?

What exactly is radiant heat? No need to worry - it has nothing to do with either ultraviolet radiation (which gives you sunburn and damages your skin) or atomic radiation (the kind from a nuclear bomb).

Rank of Solar Waves or Energy


Radiant heat is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air in between. Radiant heat is also called infrared energy (IR). The infrared segment of the electromagnetic spectrum is divided into 3 segments by wave length, measured in microns or micrometers (a micron = 1/1,000,000 of a meter):

  • 0.076-1.5 microns = near or close
  • 1.5-5.6 = intermediate
  • 5.6-1,000 = far or long wave infrared.

The infrared segment of the electromagnetic spectrum occurs just below or “infra” to red light which we perceive as heat. Our sun produces most of its energy output in the infrared segment of the spectrum. Our atmosphere allows IR rays in the 7-14 micron range to safely reach the earth’s surface. When warmed, the earth radiates infrared rays in the 7-14 micron band with its peak output at 10 microns.

The sun is the principal source of radiant energy that we experience daily. Have you ever been outside on a partly cloudy spring day of about 50º and felt quite comfortable when suddenly the sun was obscured by a cloud? Although the air temperature had not had time to drop, you felt chilled, as the cloud would not let the warming infrared rays through to reach you. The infrared heat in this sauna is just like the heat from our sun or that which our own bodies produce as they burn fuel to keep us warm.

Recent books such as "Cross Currents" by Robert O. Baker, M.D. have detailed the hazards of exposure to certain kinds of electromagnetic fields such as those encountered under high tension power lines or while working at computer display terminals. Researchers have reported that infrared radiant heat antidotes the negative effects of such toxic electromagnetic sources. Salus Saunas saunas have been tested and found to be free of such so-called “toxic” electromagnetic fields.

The majority of the sun's energy or photons (safest and most beneficial) is Infrared, which is responsible for:

  • Photosynthesis
  • Lowers lactic acid
  • Stimulates the brain
  • Kills organisms
  • Penetrates tissues
  • Stops swelling
  • Improves lymphatic flow
  • Attracts calcium to cell membranes
  • Detoxifies by vibrating ionic bonds and reducing the size of water clusters
  • Creates a resonance dance between water and chemical molecules
  • Facilitates water in moving stored toxins out of the cell and into sweat
