SLEEP 2013: Melatonin May Improve Sleep and Cognition at High Altitudes

According to a new study conducted at Mt. McKinley, the highest peak in North America with a summit height of 20,320 feet, melatonin may help to improve sleep and even cognition at high altitudes. The study, conducted by Christopher Jung, PhD from the University of Alaska at Anchorage, demonstrated that after taking melatonin, subjects fell asleep faster and experienced less wakefulness during the night. In addition, the average reaction times the next day were improved, as measured by the Stroop test, which could aid safety in the dangerous environment. "Many high altitude climates are extreme and dangerous, often requiring split-second decisions to be made during climbing and military operations," said Jung. "Melatonin is a safe and natural supplement that improves cognitive function and sleep." The relatively small study included 13 climbers and was randomized and placebo-controlled. The overnight study time included portable sleep monitoring for 2 nights at 14,200 feet. The melatonin and placebo pill were each taken 90 minutes before chosen bedtime. The research is among the findings being presented this week at SLEEP 2013, the 27th annual meeting of the American Academy of Sleep Medicine (AASM) and the Sleep Research Society. The meeting concludes on June 5 in Baltimore.
