UVB (280-315 nm) has been directly applied to the wounded tissue to stimulate wound healing, and has been widely used as extracorporeal UV radiation of blood to stimulate the immune system.

When it comes to soft tissue injuries like sprains and strains, red light therapy may both promote healing and offer pain relief as well. “A small study showed that ankle sprains treated with light therapy had less swelling at 24, 48, and 72 hours compared to rest, ice, compression, [and] elevation,” noted Dr.Jan 28, 2019

Unlike ultraviolet light - which has damaging effects upon the tissues and cells of the body - infrared light helps cells regenerate or repair themselves. Infrared light also improves the circulation of oxygen-rich blood in the body, promoting faster healing of deep tissues and relieving pain.Jan 8, 2019

If you're wondering how often you should use red light therapy for the best results, the short answer is that there is no one-size-fits-all solution. But most people get good results with a 15-minute daily session 3-5 times per week for several months.

It's recommended to start using the light therapy three to five times per week for the first few weeks, then two to three times for weeks four through 12, and then one to two times a week to maintain results, or however you see fit—it depends on the intensity of your acne or scarring.Aug 14, 2021

• Red light therapy is an every-day term for the science of photobiomodulation. It has been proven effective for a wide range of healing and rejuvenating uses including anti-aging, hair loss prevention & regrowth, skin conditions, wound care, pain relief, and much more. It is a 100% natural therapy with zero side effects.

• “Red light therapy benefits include enhancing the production of ATP (adenosine triphosphate), which is the energy currency our bodies use to do things, whether it’s to contract a muscle, digest food, or solve a math problem,”says Jennifer Novak, Atlanta-based strength coach and owner of PEAK Symmetry Performance Strategies.

• Red light therapy is a branch of light therapy. In simple terms, it uses red light to aid in healing and repairing your cellular tissue. This treatment can be used to heal an ever-growing number of healthcare issues.

• The red light therapy for muscle pain is a natural and photonic therapy, which helps to control pain and promote healing. The treatment works for both humans and animals for controlling pain. The therapy provides a fast pain relief with almost no side effects at all.

The wavelengths are measured in nanometers (nm), and those with the most therapeutic value include red light (630nm to 660nm) and near-infrared light (810nm to 850nm); collectively, these are called “red light therapy.” Near-Infrared light therapy for wound healing works by penetrating deeper into the body.

Studies confirm the healing properties of LED light therapy, especially for treating burns, healing wounds and scars, recovering from injuries and surgeries, and managing pain and inflammation. LED light therapy is a painless, safe, and non-invasive treatment that uses light to deliver concentrated energy deep into your tissue.

Results: Illumination substantially influenced wound healing. Blue light significantly decreased wound size on day 7, which correlated with enhanced epithelialisation. Light also affected mRNA expression.

NASA astronauts have trouble healing injuries while on space flights. While studying the effects of red lights on plants, the scientists tending the plants found that their hand wounds healed faster when exposed to LED lights.
