If you didn't sleep well last night you may be able to blame the moon!
In a new swiss study, thirty adult volunteers went to a sleep lab where their brain patterns and hormone levels were monitored overnight.
Researchers found it took participants five minutes longer to fall asleep, and they slept twenty minutes less, during a full moon.
they also found hormones related to sleep were lower, and brain activity associated with deep sleep went down thirty percent!
However, the participants were in a controlled lab environment. the researchers say modern influences, like electric light, may mask the moon's effect.
They say the link between lunar patterns and sleep dates back to a time when the moon synchronized human behavior. this is well documented in other animals -- like marine life -- where moon light coordinates reproduction.
