If you can't sleep, it could be because of a full moon. Scientists say there is a link between the Moon and our sleeping patterns. They say that on nights before a full moon, people have more problems sleeping. This could be because of the Moon's brightness. This makes sleeping more difficult. The scientists said moonlight is "so bright" that even if there is no other light, moonlight could change our sleep patterns at night.

The scientists studied the sleep patterns of over 500 people. There were 98 people from a village that had no electricity or other lights. Scientists compared their sleep patterns to 464 people living in a U.S. city. The scientists said people in the village and in the big city got less sleep on nights before the full moon. The light in cities does not seem to affect sleeping patterns. The scientists said human sleep is linked to the changing of the Moon.
