A new study has found that camping out for a few days and nights can re-set the biological clocks of people who have trouble sleeping and getting up in time for work.
According to researchers from the University of Colorado Boulder, given the chance, our bodies naturally adjust to the light-dark cycle of the rising and setting of the sun.
In today’s world, artificial lighting, long hours indoors and computer technology has pushed our internal clock back two hours. To determine how much electrical lighting has affected our internal body clocks, the study took eight people camping for two weeks with no access to artificial light beyond a campfire.
After a week of being exposed to nothing but natural lighting, their body clocks were roughly set two hours back, with participants awaking a daybreak and ready for bed when the sun went down.
Researchers believe that this link can be attributed to exposure to sunlight, “By increasing our exposure to sunlight and reducing our exposure to electrical lighting at night , we can turn our internal clocks and sleep times back, and likely make it easier to awaken and be alert in the morning” Professer Kenneth Wright says.
