You have probably seen it in movies: When the moon is full, a man turns into a hairy, frightening creature and runs around the city, tearing people to pieces. You may laugh at stories of wolf men, but do you really believe that there is an association between a full moon and crazy happenings?
    Many medical workers, for example, are convinced that the number of emergency cases increases during a full moon. Considerable research has been conducted to establish a link between the cycle of the moon and the biological clocks of humans and other animals, with varying results.
    One study in the United States found that people drink less alcohol and eat more during a full moon. Italian researchers found that more babies seem to be born in the one or two days following a full moon. And Britain’s largest telecommunication company claims that Internet use increases during the seven days before a full moon.
    Other researchers, however, argued against the claim and believed no direct link was found between the phases of the moon and the attacks of depression or craze.
    With only weak scientific evidence relating madness to the moon, perhaps the best way to explain the existence of this myth is to call it a relic of the past: Long before electricity, bright moonlight was an invitation for extra nighttime activity.[3]And for some people, even just one night without sleep is enough to induce craze in them — whether or not they have hair on their hands.
