Artificial light sources can negatively affect circadian rhythms, scientists say

Throughout most of human history, humans went to bed shortly after the sun went down and woke up in the morning as it rose. There were candles and later oil lamps, but the light was not very bright so people still went to bed early.
Scientists at the University of Colorado Boulder found that if you live by the sun’s schedule, you are more likely to go to bed at least an hour earlier, wake up an hour earlier, and be less groggy, because your internal clock and external reality are more in sync. The sun adjusts your clock to what may be its natural state, undoing the influence of light bulbs.
The work is published in the current issue of the journal Current Biology.
The disconnect between the outside environment and sleep is one reason why even native Alaskans have problems sleeping in the almost endless days of the Arctic summers, and get depressed during the long nights of winters.
The subjects in the Colorado study lived more normal lives.
