Researchers at the Colorado School of Public Health have found high school athletes competing at higher elevations suffer fewer concussions than their sea-level counterparts. The reason: a phenomenon attributed to physiological changes in the brain that causes it to fit more snuggly in the skull. The results showed a 31 percent decrease in concussion rates among athletes playing at 600 feet above sea level, and higher. Aspen Public Radio’s Marci Krivonen spoke with Dr. Dawn Comstock. She co-authored the study.
