Lunar effect

The term lunar effect refers to correlations between specific stages of the roughly 29.5-day lunar cycle and behavior in humans or other living things. In some cases these rhythms may depend on external cues, such as a greater or smaller amount of moonlight due to the moon's phases. In other cases, for example the approximately-monthly cycle of menstruation, the correlation in timing may reflect no known lunar influence. Some purported effects cannot simply be explained by variation in light levels. The moon does influence the behavior of several animals, as described below.
