    Nightlighting and the moon
    See also: Culture and menstruation and Lunar effect
    The word "menstruation" is etymologically related to "moon". The terms "menstruation" and "menses" are derived from the Latin mensis (month), which in turn relates to the Greek mene (moon) and to the roots of the English words month and moon.

    Some authors believe that, historically, women in traditional societies without nightlighting ovulated with the full moon and menstruated with the new moon, and one author documents the controversial attempts to use the association to improve the rhythm method of regulating conception.

    Some studies in both humans and other animals have found that artificial light at night does influence the menstrual cycle in humans and the estrus cycle in mice (cycles are more regular in the absence of artificial light at night). It has also been suggested that bright light exposure in the morning promotes more regular cycles. One author has suggested that sensitivity of women's cycles to nightlighting is caused by nutritional deficiencies of certain vitamins and minerals.

    A meta-analysis of studies from 1996 showed no correlation between the human menstrual cycle and the lunar cycle. Dogon villagers did not have electric lighting and spent most nights outdoors, talking and sleeping; so they were an ideal population for detecting a lunar influence; none, however, was found.
