How Exactly Does Infrared Heat Work in the Human Body?

Scientific studies have shown that infrared heat can benefit the body in many ways, including reducing inflammation and improving various medical conditions. This begs the question: How exactly does it work?

Far infrared heat (FIR) is a type of electromagnetic radiation that is perceived in the human skin as pure radiant heat. Its wavelengths are believed to penetrate the skin 2-3 cm deep.  

Sub-optimal nutrition, various medical conditions, poor sleep, emotional stress, a sedentary lifestyle, and even overtraining can cause inflammation in the body to rise.  When this occurs, the immune system sends out inflammatory “messengers” that work to increase inflammation and cause damage to tissues.

Studies have shown that infrared heat significantly reduces multiple measures of inflammation. Additionally, it increases blood flow and improves circulation, resulting in quicker muscle recovery after exercise. It even improves the inner lining of blood and lymphatic vessels, resulting in enhanced cardiovascular health and detoxification.

With each of these mechanisms in mind, it is no surprise that studies have shown that infrared heat may help improve multiple inflammatory conditions, including chronic pain, arthritis, high blood pressure, type-2 diabetes, kidney disease, chronic fatigue, fibromyalgia, and various autoimmune diseases.
