Sleep awareness and health

(KGUN) — Dr. William D. Scott Killgore is the Director of the Social, Cognitive and Affective Neuroscience lab at the University of Arizona. He’s been studying sleep issues for years; and says using blue light therapy is one way to get a good night's sleep.

“We use a blue light wavelength light therapy device to regulate what’s called the circadian rhythm,” Killgore said. "The rhythm really determines when you are most likely to sleep and wake up."
