Early morning blue light exposure therapy can aid the healing process of people impact by mild traumatic brain injury, according to new research from the University of Arizona.
“Daily exposure to blue wavelength light each morning helps to re-entrain the circadian rhythm so that people get better, more regular sleep. This is likely true for everybody, but we recently demonstrated it in people recovering from mild traumatic brain injury, or mTBI. That improvement in sleep was translated into improvements in cognitive function, reduced daytime sleepiness and actual brain repair,” said William D. “Scott” Killgore, psychiatry professor in the College of Medicine – Tucson and lead author on a new study published in the journal Neurobiology of Disease.
