An athlete's risk of concussion may drop as altitude rises.
Researchers looked at concussion statistics for high school athletes across the country.
Concussion rates were 31% lower among schools located at elevations of 600 feet and above.
Although the reasons are still unclear, experts say high altitudes may cause the brain to swell slightly and fit tighter in the skull. Experts say that makes it less likely to move around during a hit to the head.
