photobiomodulation (PBM), low level light therapy (LLLT), biostimulation, photonic stimulation or light box therapy.
This therapy uses specific wavelengths of light to treat the skin to accomplish various outcomes. Studies have shown that different wavelengths affect the body in different ways. The most effective wavelengths of red light seem to be in the ranges of 630-670 and 810-880.
* Better Circulation and Collagen Production
When the light penetrates through the epidermal and dermal skin layers, it increases circulation to help form new capillaries. It also increases collagen production and fibroblasts. While topically applied collagen is useless, I frequently consume it for the health of my nails, skin, hair and joints. Red therapy light improves collagen levels naturally by triggering the body to produce more of its own. Since collagen comprises about 70% of the protein in our skin, it’s a big deal!
* Wound Healing
Fibroblasts in our skin synthesize collagen, maintain connective tissue and are integral to wound healing. Red therapy light stimulates fibroblasts to do their job, and increases circulation for faster wound repair time. People have also used this therapy for burns, amputation injuries, skin grafts and infected wounds. It’s been successfully used for skin damage caused by cancer treatments, including those in the mouth and mucus membranes.
* Remedy for Hair Loss
I have plenty of natural remedies on my site for how to improve hair growth, but red light therapy may be another way to reverse balding. A 24 week study demonstrated that red therapy light significantly improved hair density and hair thickness without any serious reactions. Participants wore a helmet that emitted red therapy light to achieve this effect, though I’ve found that bigger devices (like this one) are easier to use and benefit the rest of the body as well.
* Recover Faster from Injury and Illness
Red light therapy increases circulation and ATP production throughout the body which may help speed healing during times of illness. It also stimulates lymph system activity and phagocytosis, the process of cells cleaning house.
One of the big reasons I started looking into red light therapy is because of the potential for improved thyroid function. There are several compelling studies that look at the benefits of red light and near infrared therapy for thyroid health. As someone who has struggled with Hashimoto’s Thyroiditis, I was interested in trying this kind of therapy.
