MOON LUNAR CYCLE FULL
The position of Earth’s natural satellite in relation to the sun changes during its orbit, causing the familiar luminance cycle between the new and full moon every 29.5 days. To examine whether moon cycles influence human menstrual cycles, Helfrich-Förster and her colleagues examined 22 women who recorded the date their period started for five to 32 years.Īs the moon makes its 27.3-day journey around the Earth, it exhibits three different lunar cycles: the luminance cycle, the perigee-apogee cycle, and the lunar standstill cycle. “On the other hand, it is very interesting that the cycle length is more or less the moon cycle length, and it’s known from many studies that animals-at least marine organisms-rely on the moon for synchronizing their reproduction,” she says. “But it’s really cool that this puts fresh spirit into the whole discussion: is the moon-yes or no- human biology.”Ĭharlotte Helfrich-Förster, a chronobiologist at Julius-Maximilians University of Würzburg in Germany and the lead author of the study, says she was initially “skeptical” of a link between lunar menstrual cycles. “ has not completely settled the debate,” says Kristin Tessmar-Raible, a chronobiologist at the University of Vienna who was not involved with the research. In a study published January 27 in Science Advances, researchers analyzed long-term data from women and found that for some their periods synced with lunar light and gravity cycles at certain times in their lives. The celestial body’s influence on humans biology had largely been dismissed as myth, but several recent studies have linked lunar phases with sleep and moods.
As the average length of women’s menstrual cycles matches the moon’s 29.5-day waxing and waning cycle, many cultures associated the moon with fertility.
