Full Moon does Cause Poor Sleep

By Selina Haefeli

A new study confirms that lunar cycles really do influence our sleep patterns.

Although many people complain about having a restless night’s sleep around full moon, the association has often been put down as a myth—along with other old wives’ tales such as stuffing garlic in your shoes to cure a cold.

Swiss scientists, however, have finally determined that lunar cycles do affect our sleep patterns. In fact, by measuring brain activity using a technique called electroencephalography (EEG) they found that people slept 20 minutes less per night and had 30 percent less deep sleep during a full moon.

“A lot of people are going to say, ‘Yeah, I knew this already. I never sleep well during a full moon.’ But this is the first data that really confirms it,” said biologist Christian Cajochen, who is the lead author of the new study published in Current Biology, in a statement. “There had been numerous studies before, but many were very inconclusive.”

In the experiment, volunteers were in a closed room where they couldn’t see the moon before they drifted off to sleep. This raises the question of how the body ‘knows’ when it is a full moon and what mechanism, if it’s not direct moonlight, produces the effect on our sleep. This is the question the scientists suspect future studies will be concerned with.

The word lunatic is derived from the Latin for “moon-sick”, which denotes the traditional link made between madness and phases of the moon cycle.
