660 850 light therapy, also known as red and near-infrared light therapy, is a non-invasive treatment that uses specific wavelengths of light to promote healing and pain relief in the body. This therapy has been found to have various benefits in reducing body pain, including:

1. Increased blood circulation: Red and near-infrared light therapy can improve blood flow and oxygenation in the targeted area, which can help reduce pain and inflammation.

2. Reduced inflammation: The therapy has anti-inflammatory effects, which can help alleviate pain caused by inflammation in the body.

3. Enhanced cellular repair and regeneration: The specific wavelengths of light used in this therapy can stimulate the production of ATP (adenosine triphosphate) in the cells, which is the energy source for cellular repair and regeneration. This can aid in healing damaged tissues and reducing pain.

4. Nerve pain relief: Light therapy can help calm overactive nerves and reduce nerve pain by modulating the activity of pain receptors.

5. Muscle relaxation: The therapy can promote muscle relaxation by reducing muscle tension and spasms, which can be beneficial for relieving pain associated with muscle strains or injuries.
