New evidence that the phases of the moon affect our sleep

According to a new study, our sleep may depend on the phases of the moon. Not only does the moon dictate the tides, but it also affects our circadian rhythms.

In the days leading up to a full moon, people go to bed later and sleep less, according to a study published in Science Advances Wednesday. On average, participants went to bed 30 minutes later and slept 50 minutes less the night before the full moon, said study co-author Horacio de la Iglesia, a professor in the Department of Biology at the University of Washington in Seattle.

“We believe this modulation evolutionarily provided the benefits of such moonlit nights, which can be useful for safe outdoor activities such as hunting or fishing, or for engaging in social interactions with other groups,” the experts said.

In urban communities, participants go to bed even later at this time and sleep less than participants in rural communities.
