Red Light Therapy - Photobiomodulation (PBM) vs Far-Infrared Saunas

What’s the Difference Between the TheraLight 360 and Far-Infrared Saunas?
Red light therapy, also referred to in clinical contexts as “photobiomodulation,” is fundamentally different from far-infrared saunas. Saunas emit far-infrared wavelengths that produce heat and can activate sweat glands. These far-infrared waves are highly warming, which contrasts with the typically non-thermal application of photobiomodulation.

Far-infrared saunas operate by emitting waves that interact with water molecules in the body. This interaction generates warmth and promotes perspiration, which some users associate with detoxification through sweating.

Red light therapy, on the other hand, involves the use of red and near-infrared wavelengths (generally between 600–1,100nm). In full-body light bed systems like TheraLight 360, this light is generally non-thermal. The light is absorbed at the cellular level, particularly by structures such as mitochondria. This process is currently being studied for its potential role in supporting normal cellular function, including processes related to energy metabolism (ATP production).

Summary

Far-Infrared Saunas: Use far-infrared heat to warm the body and promote sweating. Often used in wellness routines that involve heat-based relaxation.

Red Light Therapy: Uses near-infrared cold light, which is being studied for its potential role in supporting natural cellular function and energy metabolism.
