What are the Types of Infrared Light Therapy? Uses, Benefits & Risks

What is Infrared Light Therapy?

Infrared light therapy is a form of treatment that uses infrared light to penetrate the skin and stimulate healing within the body. This type of low-level laser therapy has been used for centuries to treat various ailments and conditions, including pain relief, inflammation reduction, and improved circulation.

The way infrared light therapy works is by a light device emitting infrared light waves that are absorbed by the body's cells. These light wavelengths then stimulate the production of nitric oxide, a molecule that helps relax blood vessels and improve blood flow. This increased circulation can help reduce pain and inflammation in the affected area.

Infrared light therapy is a non-invasive and drug-free treatment option that can be used alone or in conjunction with other therapies to promote healing and overall well-being. Its effectiveness has been supported by numerous studies, making it a popular choice for those seeking natural remedies for their health concerns.
