Some authors believe women in traditional societies without nightlighting ovulated with the full moon and menstruated with the new moon. A few studies in both humans and animalshave 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), though none have demonstrated the synchronization of women’s menstrual cycles with the lunar cycle. 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.[53]

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—reflecting the fact that the moon also takes close to 28 days to revolve around the Earth (actually 27.32 days). The synodical lunar month, the period between two new moons (or full moons), is 29.53 days long
