A study done by the Psychiatric Hospital of the University of Basel in Switzerland investigated if full moons really do throw off human sleep cycles. The scientists used 33 healthy volunteers ranged from ages 20 to 74. Each participant slept in a room with no windows so they could not see the moon. As it turns out, the researchers found out that a full moon was associated with a 20-minute reduction of total sleep. They study also found that it took participants longer to fall asleep during and near full moons. For more details on the study and its results, click HERE.
