Infrared sauna therapy uses infrared light (near, mid, or far wavelengths) to heat the body directly, rather than heating the surrounding air. This produces deep, gentle warmth that raises core temperature, promotes circulation, and induces sweating — typically at a lower air temperature (45–60 °C) compared to traditional saunas (70–90 °C).
Infrared saunas are used for relaxation, recovery, detoxification, cardiovascular support, and overall wellness.
Infrared radiation penetrates tissues up to 3–5 cm deep.
Increases core body temperature and triggers vasodilation, improving blood flow and oxygen delivery.
Stimulates mitochondrial ATP production (especially in near-infrared range).
Enhances sweating and metabolic activity, aiding thermoregulation and toxin elimination.
Activates heat-shock proteins, which help protect and repair cells from oxidative stress.
Promotes parasympathetic (rest-and-digest) response, lowering stress hormones and improving relaxation.
Here are the benefits of red light therapy (RLT):
