Scientists uncover strange link between women's menstrual cycles and the moon trends now
The lunar calendar has long been associated with women's menstrual cycles, but a new study has officially revealed the two are intrinsically linked.
Researchers from France and the US analyzed menstrual cycle data from 3,296 European women and 721 North American women, and looked to see if the dates fell on specific lunar cycles.
The team found that women in North America would more often begin their period when there was a full moon and Europeans during a waxing crescent.
Researchers believe the syncing may stem from their new findings that mensuration is governed by a woman's internal clock, which can be impacted by the lunar cycle.
Researchers have found that the moon plays a role in women's menstrual cycles because it controls the body's circadian rhythms which tells the woman's body that it's time for their cycle to begin
The clock controls our body’s daily (or ‘circadian’) rhythm in a 24-hour cycle, which is responsible for waking our bodies up in the morning and ensuring they get a good night's rest.
However, it has also been noted that our internal clocks can be impacted by the lunar cycle that can cause people to lose sleep - and a disruption of circadian rhythms is associated with disturbances in menstrual function.
This changes how our internal clock is calibrated, so 'if the cycle lengthens, for any reason, this clock-based process adapts to quickly shorten it,' neuroscientist Claude Gronfier, from The University of Lyon in France, told BBC Science Focus.
The researchers found that when this happens, it creates something called 'phase jumps,' when the biological clock becomes out of sync because of the waxing moon and tries to self-correct by moving forward to the body's next stable state.
A phase jump is also known as 'relative coordination' which occurs in circadian clocks such as the fatigued and out-of-sync feeling you get when you travel across time zones.
