Quick Answer Transcranial photobiomodulation, or tPBM, uses red or near infrared light on the head to support brain function. Early research suggests it may help support mitochondrial energy production, cerebral blood flow, inflammation balance, attention, working memory, and executive function. The evidence is promising, but larger clinical trials are still needed. What Is Transcranial Photobiomodulation? […]

The use of red light therapy for thyroid conditions, particularly Hashimoto’s thyroiditis and hypothyroidism, has generated interest since a notable Brazilian clinical study was published in 2013. Here’s an honest look at the evidence. New to photobiomodulation? Explore the complete Red Light Therapy Guide covering wavelengths, dosing, treatment distance, near infrared light, and how modern

Wound healing is one of the oldest and best-documented applications of photobiomodulation. The research spans four decades, multiple wound types, and dozens of RCTs. Here’s what we know. New to photobiomodulation? Explore the complete Red Light Therapy Guide covering wavelengths, dosing, treatment distance, near infrared light, and how modern red light therapy panels work. Why

Arthritis, whether osteoarthritis (OA) or rheumatoid arthritis (RA), involves joint pain, inflammation, stiffness, and progressive tissue changes that can significantly affect mobility and quality of life. Photobiomodulation (PBM), also known as red light therapy or low level light therapy (LLLT), has been studied for decades as a potential supportive therapy for arthritis-related symptoms. What the

The idea that light could influence mood and brain function may sound unconventional, but transcranial photobiomodulation (tPBM) has become a growing area of neuroscience research over the past decade. Researchers are investigating whether specific wavelengths of near infrared light can influence brain metabolism, inflammation, and neural activity in ways that may support mood and cognitive

Inflammation is one of the most widely studied targets of photobiomodulation (PBM), also known as red light therapy. Researchers have spent decades investigating how red and near infrared light interact with inflammatory pathways, mitochondrial function, and tissue recovery. While the evidence varies by condition and treatment protocol, the overall research trend is promising. Studies have
