Our Biological Clocks

Our Internal Clocks are Out of Sync


Chronic disruption of our circadian rhythm, our 24-hour internal timing system, can have a major impact on health consequences. UCLA Chancellor Gene Block, Distinguished Professor of Psychiatry and Biobehavioral Sciences, specializes in circadian biology and has described the science behind the circadian rhythm and has offered recommendations for good sleep hygiene in his article in the Wall Street Journal.

Blue-Green Wavelength Reduction at Night

In a recent, randomized controlled study of about 120 UCLA undergraduate students, our Mind Well U-Reviews Sleep Well team found that students who had a real f.lux blue-green wavelength reduction at night relative to no change showed a small but significant change in sleep onset latency. Also, we found a small but significant correlation of hours of sleep one gets a night (pre) and GPA and a significant reduction in sleep problems over time, independent of the f.lux intervention, suggesting perhaps that just making students aware of sleep problems might have some benefit (research article in development).
