Feature: 1. Pain Relief: Infrared light therapy device can increase cell metabolism and promote the repair of cell tissues, directly affect the pain point, and effective alleviate pain. 2. Deep Penetration: Infrared light can penetrate deep into the skin, absorbed by mitochondria in cells, thus improving the activity of mitochondria and releasing more nutrients. 3. Promote Circulation: Red therapy lamp can provide infrared rays, penetrate deep into tissues and bones, creating a thermal effect that increases blood circulation, relieves pain and relaxes muscles. 4. Widely Use: Handheld red therapy lamp with a tripod for convenient use, very suitable for back, neck, shoulders, knees, hands and other areas to relieve joint pain, muscle fatigue and soreness. 5. Promote Recovery: Infrared light with a 30° optical glass lens, can increase the irradiance of 120mW/cm² at a distance of 1 inch, improving the therapeutic effect and shortening treatment time. Specification: Item Type: Red Light Therapy Device Material: ABS Battery Type: Lithium Battery 2000mAH(Included) Note: 850NM can not see by human eyes Application Description: Light physical therapy effect, through the method of physics, it emits 630nm, 660nm and 850nm light wavebands (in the same waveband as the He-Ne laser, deep penetration, red light penetrates the human body and the red light waveband optical effect (after the red color), the effect of light on the activity of mitochondrial catalase increases, enhances cell metabolism and protein synthesis, promotes local blood circulation, and controls the increase in infection..
