Red light therapy prevents brain inflammation in football players

Red light therapy has been shown to reduce brain inflammation, protecting people who experience head trauma from long-term health consequences, a University of Utah study has shown.Brain damage from repeated impact over the years is known to cause cognitive symptoms, ranging from memory issues to full-blown dementia, particularly affecting soldiers and athletes.Chronic traumatic encephalopathy (CTE) is a progressive, degenerative brain disease linked to repeated head impacts rather than a single injury, according to Mayo Clinic.ALZHEIMER’S SCIENTISTS FIND KEY TO HALTING BRAIN DECLINE BEFORE SYMPTOMSMore than 100 former NFL football players have been posthumously diagnosed with CTE, according to the new study, which was published in the Journal of Neurotrauma.Other research has shown that military personnel in active combat suffer from similar issues, as do first responders and veterans. The treatment was administered three times a week for 20 minutes using specialized headsets and intranasal devices designed to penetrate the skull. (iStock)In the new study, the researchers recruited 26 current football players to understand more about the impact of red-light therapy on brain injuries.The participants received either red light therapy delivered by a light-emitting headset and a device that clips into the nose, or a placebo treatment with an identical device that doesn’t produce light. Players self-administered the therapy three times a week, 20 minutes each time, for 16 weeks.CLICK HERE FOR MORE HEALTH STORIES”My first reaction was, ‘There’s no way this can be real,’” said first author Hannah Lindsey, Ph.D., in the university press release. “That’s how striking it was.” Specific wavelengths of light are believed to enter the brain and reduce molecules that trigger inflammation, potentially halting the path toward dementia and other cognitive conditions. (iStock)Players using the placebo treatment experienced increased brain inflammation over the course of the season. Magnetic resonance imaging (MRI) scans taken at the end of the season showed significantly more signs of inflammation than at the beginning of the season, the study found.For players who used red-light therapy during the season, their brain inflammation didn’t increase at all.ALZHEIMER’S RISK COULD RISE WITH COMMON CONDITION AFFECTING MILLIONS, STUDY FINDSPrevious studies have shown that red light, if powerful enough, can penetrate the skull and reach the brain, where it may reduce inflammation-related molecules.CLICK HERE TO DOWNLOAD THE FOX NEWS APP”When we first started this project, I was extremely skeptical,” said Elisabeth Wilde, Ph.D., the senior author on the study. “But we’ve seen consistent results across multiple of our studies, so it’s starting to be quite compelling.”Study limitationsThe study was conducted using a small sample size, which led to different levels of inflammation in the treatment and control groups, the researchers acknowledged. While the placebo group showed increased brain inflammation during the football season, those receiving red light therapy showed no increase in inflammatory markers.
