It’s no secret that slugging down caffeinated drinks in the evening can disrupt sleep. But a new study led by the University of Colorado Boulder and the Medical Research Council’s Laboratory of Molecular Biology in Cambridge, England shows for the first time that evening caffeine delays the internal circadian clock that tells us when to get ready for sleep and when to prepare to wake up.

Caffeine + bright light (105 min) isn’t significantly more effective than bright light alone (85 mins) or caffeine alone (85 mins)

    a 2013 study, Wright and his research team showed one week of camping in the Rocky Mountains with no artificial light, not even flashlights, synchronized the circadian clocks of the eight study subjects with the timing of sunrise and sunset.
