What Is Infrared?

Heat is heat – but sources of heat vary. Infrared commonly refers to the warm heat as related to heat from the sun. This chapter explains the electromagnetic spectrum as it applies to infrared heat, as well as how infrared saunas efficiently and effectively apply this heat for healing.

Electromagnetic Spectrum

The electromagnetic spectrum includes all waves generated from the sun. The word infrared means “below red,” as these waves are just below those of visible red light. Although we cannot see infrared light, we feel it as heat in the increased warmth of our skin. While we feel the heat from these rays, they are below the visible light spectrum and cause no damage to our skin as ultra violet rays can. Infrared waves penetrate and heat objects by exciting the molecules in the object, causing them to move together, producing heat.

Radiant Heat

Radiant heat is a form of energy that heats objects directly through conversion without heating the surrounding air. This radiant heat is from the infrared band of the electromagnetic spectrum, divided into three wavelength segments measured as microns or micrometers. The near or close infrared spectrum falls between 00.76 to 1.5 microns; the middle or intermediate between 1.5 to 5.6 microns; and the far infrared spectrum falling between 5.6 to 1000 microns. Far infrared falls just below visible light on the electromagnetic spectrum (Flickstein, 2000).
