Early morning exposure to blue wavelength light can help heal the brain following mild traumatic brain injury (mTBI), new research suggests.
Results of a small, randomized controlled trial showed blue-light therapy improved brain structure and function, cognition, and sleep in this patient population.
“We found that blue-light therapy improved patients’ daytime sleepiness,” study investigator William D. ‘Scott’ Killgore, PhD, told Medscape Medical News. “So those who got the blue light were less sleepy 6 weeks later than they had been at baseline.”
