What Is Red Light Therapy? A Detailed Beginner’s Guide

Let there be light — for your pain, skin, and injuries, that is. The possibilities of red light to treat a variety of health and aesthetic concerns are just emerging thanks to interest from researchers, universities, and hospitals, as well as at-home devices that make it more accessible.

Red light therapy (RLT) is a type of photomedicine, which is “the use of light to treat skin and other health conditions,” says Jared Jagdeo, MD, the founding director of the Center for Photomedicine at SUNY Downstate Health Sciences University in Brooklyn, New York.

Here, learn about the history of the therapy, how it works, its potential benefits, what to expect from treatment, and more.

Hope Springs for Long Covid Patients

Until now, the medical prospects for persons suffering from long Covid have been very bleak. As recently as three weeks ago, BizNews republished an article by our partners at The Wall Street Journal covering long Covid. The central message and, essentially, advice to patients struggling with long Covid symptoms was to pace themselves. Neither heartening nor motivational advice for those who find themselves incapable of functioning as a consequence of debilitating fatigue and cognitive dysfunction.

However, there is hope. Dr Ashleigh Bhanjan, a Specialist Neurologist and Bioflex Laser Therapy Practitioner working at Life Entabeni Hospital,  Durban Neuro Laser Clinic, has been treating long Covid with photobiomodulation therapy, with highly encouraging results. BizNews spoke to Dr Bhanjan who provided great insight on long Covid, including those who are at risk, the correlation between persons with severe Covid-19 infections and those who are likely to develop long Covid (spoiler alert – no correlation) and photobiomodulation therapy. – Nadya Swart

Light Therapy for Cancer Treatment

NASA Research Illuminates Medical Uses of Light

Experimentation helped demystify, legitimize, and simplify medical uses for long-known but little-understood light therapy.

Can light help a wound heal faster? Alleviate pain? Prevent loss of eyesight?

Although decades of studies indicate it can – including extensive research funded by NASA – the mounting evidence hasn’t always drawn the attention that might be expected for such a striking discovery.

This may be because the science behind it hasn’t been well understood. For example, although a Danish physician received a Nobel Prize in 1903 for discovering that exposure to concentrated red light accelerated the healing of sores, he remained reluctant to put it into practice without understanding why it worked.

A larger barrier to acceptance, though, has probably been that it simply sounds unbelievable.

In a 1989 paper about the health benefits of low-powered laser light, biophysicist Tiina Karu noted that the treatment appeared “highly incredible and even mysterious.” What’s more, she wrote, its effectiveness against many different ailments only added to doubts by creating the appearance of a proverbial snake-oil panacea.

Interview with Rico Petrini: his experience with light therapy for symptoms of repetitive head impacts and potential CTE

In an interview, Rico Petrini discusses his potential CTE and his positive experience as a participant in a photobiomodulation study conducted by The University of Utah TBI and Concussion Center, Department of Neurology School of Medicine. The study authors are finalizing the data for their study, Use of PBM to Improve Brain Health and Resiliency in Individuals with Repetitive Head Hits: A Pilot Study.

Rico spoke with Concussion Alliance Co-founders and Co-executive Directors Malayka Gormally and Conor Gormally on January 18th, 2022.

Shepherd University Expands Wellness Center With Laser Pain Treatment

Shepherd University officials held a ribbon cutting ceremony Monday for the expansion of a pain clinic at the school.

The clinic uses a process called photobiomodulation, or PBM. It uses laser light therapy to reduce pain from degenerative diseases.

A PBM bed is included in the university’s Wellness Center expansion and will be used to help those in and around the school’s community. The school received $500,000 through the state’s federal COVID relief funds for the clinic’s expansion.

Doctors Increase Use of Light Therapy to Manage Pain

The opioid epidemic has led medical professionals and patients to explore alternatives to potentially addictive pharmaceuticals, such as light therapy.

Photobiomodulation (PBM) therapy, a form of light therapy using red and near-infrared light to stimulate cell growth and reduce inflammation, is gradually gaining acceptance by the medical community. The noninvasive technology, discovered in 1967, is approved by the U.S. Food and Drug Administration (FDA) to manage pain and treat a variety of medical conditions.

Patients receive therapy several times a week for several weeks before they see pain relief.

Photobiomodulation: Evaluation in a wide range of medical specialties underway

Advances in photobiomodulation have propelled the use of therapeutic applications in a variety of medical specialties, according to Juanita J. Anders, PhD.

During the annual conference of the American Society for Laser Medicine and Surgery, Dr. Anders, professor of anatomy, physiology, and genetics at the Uniformed Services University of the Health Sciences, Bethesda, Md., defined photobiomodulation (PBM) as the mechanism by which nonionizing optical radiation in the visible and near-infrared spectral range is absorbed by endogenous chromophores to elicit photophysical and photochemical events at various biological scales. Photobiomodulation therapy (PBMT) involves the use of light sources including lasers, LEDs, and broadband light, that emit visible and/or near-infrared light to cause physiological changes in cells and tissues and result in therapeutic benefits.
