Which therapy utilizes electromagnetic radiation?

Light therapy utilizes electromagnetic radiation, which encompasses a range of wavelengths that includes visible light, ultraviolet light, and infrared light. This form of therapy is often employed for various medical conditions, improving skin health, enhancing mood, and aiding in the treatment of seasonal affective disorder as well as certain skin conditions like psoriasis.

The effectiveness of light therapy stems from its ability to penetrate the skin and interact with biological tissues, which can lead to beneficial physiological changes. By utilizing specific wavelengths of light, practitioners can target and regulate cellular functions, promote healing, and enhance overall wellness.

In contrast, cryotherapy employs cold temperatures to reduce inflammation and numb pain, thermotherapy uses heat to increase blood flow and relax muscles, and hydrotherapy involves the use of water in various forms to promote healing and recovery. These therapies do not primarily rely on electromagnetic radiation, distinguishing them from light therapy.
