Previous research has analyzed variations in sleep patterns, including number of hours slept, quality of sleep, and sleep-wake times, and found an association with cognitive impairments, health, and performance. However, few studies have considered or accurately quantified the effects of regular sleep patterns.

In a new study at Brigham and Women’s Hospital (BWH), researchers objectively measured sleep and circadian rhythms, and the association to academic performance in college students, and found that irregular patterns of sleep and wakefulness correlated with lower grade point average, delayed sleep/wake timing, and delayed release of the sleep-promoting hormone melatonin. The results were published in Scientific Reports on June 12, 2017.
