Getting Away From Artificial Lighting May Help Reset Circadian Rhythms, Improve Sleep, Study Suggests.

reports in the two-part study, researchers “equipped five people with wearable devices that measured when they woke up, when they went to bed and how much light they were normally exposed to.” The researchers “also measured their melatonin levels in a lab.” Following those assessments, “everyone went on a week-long camping trip...during the winter.” They found that “people’s internal clocks were delayed during their normal schedules” and “also had higher melatonin levels.” In the second part of the study, researchers observed people who “went camping for just a weekend” while others stayed home. Investigators found that individuals “who stayed home stayed up later than usual and slept in,” while those “on the two-day trip” saw a shift in their internal clocks. http://time.com/4656550/camping-sleep-insomnia/
