Full Moon Sleep

New research published in the journal Science Advances supports a correlation between moon cycles and sleep. Seems we go to bed later, sleep less when the moon is full. Scientists analyzed sleep patterns of two control groups, one in rural Argentina without artificial light pollution, the other college students living in downtown Seattle. Research concluded full moons disrupt sleep patterns even in urban locations with artificial light pollution. Participants wore wristbands to monitor activity, both groups went to bed later, slept less during the week leading up to a full moon. Research confirmed humanity’s inherent link to evolutionary circadian rhythms.

Circadian rhythm regulates wake/sleep hours, repeating once every 24 hours in step with rotation of Earth. Circadian (from Latin “circa” meaning around or approximately and “diem”, meaning day ) rhythm is hard wired into every form of life. It dictates when bees feed, bats fly and we sleep. Circadian rhythm is sensitive to light fluctuation – enter full moon sleep deprivation.

  1. I have always found this relationship between the moon and our various cycles particularly interesting. I suspect it has everything to do with our aquatic origins still present in our DNA, what Neil Shubin calls our ‘inner fish’.
