Infrared light therapy is a non-invasive treatment that uses infrared light to promote healing and reduce pain by penetrating deep into the skin. This therapy utilizes specific wavelengths of light, typically in the range of 700 nm to 1,500 nm, which are absorbed by the tissues and can reach muscles, joints, and bones. The heat generated from the infrared light enhances blood circulation, reduces inflammation, and stimulates cellular repair, making it effective for treating conditions like arthritis, muscle pain, and joint stiffness. It is also commonly used in physical therapy and rehabilitation settings to accelerate recovery, alleviate chronic pain, and improve overall tissue health without the need for drugs or invasive procedures. The therapy is generally considered safe and can be applied through handheld devices, light panels, or specialized infrared saunas.
