Red light therapy device delivers safe, concentrated wavelengths of natural light to your skin and cells, with no chemicals, UV rays, or excess heat. Your light works by sending out red & near-infrared light in a certain range (660nm & 850nm) of therapeutic wavelength and intensity. This device helps a number of health issues because red light therapy increases the production of adenosine triphosphate, which enhances cellular energy production and elevates protein synthesis. Guidelines It is important to use your light consistently. We recommend using your therapy belt every day, light therapy is like food for your cells. For best results, please position your light on the targeted area on your body or skin that you want to treat.Time: At least 20 minutes a day, at least 4 times a week. How to use: Equipped with a 20-minute automatic shutdown function, one use does not exceed 20 minutes, and it can be used multiple times a day. Red Light Therapy Belt Red & Near-infrared Light A natural, non-invasive safe LED therapy device. Our light delivers safe, concentrated red & near-infrared wavelengths of therapeutic 2 natural light to your skin and cells, where it reduces oxidative stress and stimulates cellular energy production. The beam angle is 60 degrees. 3 IN 1 LED DIODE Visible red light (660nm)---120PCS Invisible near infrared Light (850nm)---240PCS Reduces inflammation and swelling: In a study, the 660nm wavelength was found to reduce both inflammation and swelling by reducing the number of inflammatory cells which lead to the formation of swelling. Reduces joint pain and alleviates arthritis: Red and near-infrared light have a significant effect on reducing joint pain and increasing function and activity for people with arthritis. Relief pain caused by aseptic inflammation, such as the strain of lumbar muscles, a strain of lumbar muscles, sciatica, tendinitis, rheumatoid arthritis, etc, or sprain & swell recovery period, can all be alleviated with the red and near-infrared light devices. Read more Two Methods to Power On the Device Light therapy belt has a particularly strong ability to penetrate deeper into the tissue, organs, and joints making it ideal for enhancing muscle recovery and reducing joint pain & inflammation. The light wave with a wavelength of 660nm and 850nm belongs to low-energy light and is called the "light of life" in the gold belt of the human body by people. It can pass through human skin, fat, muscle and other tissues without harming human cells. A large amount of nano light energy is absorbed by the human body through human tissues, which has a good light therapy effect.Red light physiotherapy equipment is widely used on animals and has been well verified on horses, dogs and cats.360 pcs medical grade LED lights,120 pcs visible red lights (660 nm) and 240 pcs invisible NIR lights (850 nm). size:15.35x7.87inch.
