Myths
Does the Full Moon Affect Sleep?
Not in our data. Across 22 full moons, sleep was within a minute of a normal night on average, no different from new moon nights.
People have blamed the full moon for bad nights for centuries. We compared every full moon night since January 2025 with the same weekday in the weeks around it, and used new moons as a control.
