“Weekend exposure to natural light was sufficient to achieve 69 percent of the shift in circadian timing we previously reported after a week’s exposure to natural light,” Wright said. When the campers returned after just two days and had their saliva tested, their melatonin rise had shifted 1.4 hours earlier. In the first, his team recruited 14 volunteers: Nine went camping in Colorado's Eagle's Nest Wilderness for a summer weekend five stayed home. Just how quickly does the clock change in response to shifts in our light environment? And how big of an impact do seasonal changes have on human biological rhythms? To find out, Wright conducted the two new studies. Volunteers head out for a camping trip in Colorado's Cache La Poudre Wilderness.īut questions remained. In essence, the campers’ clock synced with the summer sun. It began to wane, signaling the biological day, earlier, too. Upon return, the onset of melatonin-a hormone that promotes sleep and physiologically prepares the body for nighttime-came nearly two hours earlier, near sunset. They were exposed to four times more light by day than usual and prohibited from using headlamps or flashlights at night. Previously, to study the impact our modern light-filled environment-or lack thereof-has on our clock, Wright for a 2013 paper sent volunteers camping for a week in the summer. But as little as a weekend camping trip can reset it.” “Living in our modern environments can significantly delay our circadian timing, and late circadian timing is associated with many health consequences. “These studies suggest that our internal clock responds strongly and quite rapidly to the natural light-dark cycle,” said lead author and CU Boulder integrative physiology professor Kenneth Wright, who believes his findings could help light-based approaches for boosting work performance, quelling seasonal depression and circadian sleep-wake disorders. Go camping in the winter, and the impact may be even more potent, the two-study paper-published today in Current Biology-found.
