It’s tempting to keep the computer running late and promise yourself an extra 30 minutes of bed rest in the morning. It’s tempting to do it again the next night, too. But sleep inevitably loses out to getting up early for school or work.
There’s a simple way to combat this: End all artificial lights at night for at least a weekend and drench your eyes in natural morning light, says Kenneth Wright, a professor of integrative physiology at the University of Colorado, Boulder and senior author on a study on resetting sleep cycles. The most straightforward way of doing this is to forbid any electronics on a camping trip.
In the study, published Thursday in Current Biology, Wright reports on the latest of a series of experiments where he sent people out camping in Colorado parks to reset their biological clocks. Small groups of people set out for a week during the summer, an experiment published in Current Biology in 2013.
This most recent study shows the results of camping a week in winter and once over a winter weekend. Others stayed at home to live their life. Along with sleep, Wright kept track of people’s circadian rhythms by measuring their levels of the hormone melatonin, which regulates wakefulness and sleep.
