===Lunar effect===
{{Main|Lunar effect}}
The lunar effect is a purported unproven correlation between specific stages of the roughly 29.5-day lunar cycle and behavior and physiological changes in living beings on Earth, including humans. The Moon has long been associated with insanity and irrationality; the words ''lunacy'' and ''[[lunatic]]'' are derived from the Latin name for the Moon, ''Luna''. Philosophers [[Aristotle]] and [[Pliny the Elder]] argued that the full moon induced insanity in susceptible individuals, believing that the brain, which is mostly water, must be affected by the Moon and its power over the tides, but the Moon's gravity is too slight to affect any single person.<ref name="sciam"/> Even today, people who believe in a lunar effect claim that admissions to psychiatric hospitals, traffic accidents, homicides or suicides increase during a full moon, but dozens of studies invalidate these claims.<ref name="sciam"/><ref name="RottonKelly1985"/><ref name="MartensKelly1988"/><ref name="kelly"/><ref name="FosterRoenneberg2008"/>
