Hi Rachel, Congrats on the release! I just thought I'd ask: I recently asked myself the question "is it a coincidence that the human menstrual cycle is the same length as the lunar cycle?" and from what I could gather - I concluded that it is just a coincidence. Can you point me in the direction of research that explains why it isn't please. I'd love to find out more.

@mrbjjackson I would take a look at this comprehensive post by Clue, another period tracking app (not moon related though) that might give you some more insight into previous studies - https://helloclue.com/articles/c.... This quote is probably the most interesting "While the data from 1.5 million Clue users who were not using any form of hormonal contraceptives indicate that naturally occurring periods do not sync with the moon, many people still find that observing the lunar cycle in relation to their menstruation has meaning for them personally."

@mrbjjackson Hey Mr. BJ Jackson! Thanks! I’m so glad you asked! Everything on our planet is effected by the Earth's rotation around the Sun and the Moon’s rotation around the Earth. Animals time migrations according to vernal equinoxes, plants bloom and die with the seasons. The ocean tides are created by the moon’s gravitational pull on the earth...The reproductive cycle of many plants and animals (and most coral!) is timed by the moon. Finally, is anything really a coincidence? ✨ Here’s some reading for you: https://scijinks.gov/tides/#:~:t.... https://www.nhm.ac.uk/discover/h...,' https://pubmed.ncbi.nlm.nih.gov/...

@lauren_cucinotta Hi Lauren! Have a look at the work of Dr. Christiane Northrup who argues that there is indeed a Lunar-Menstrual Synchronicity but our contemporary exposure to light/electricity could be affecting it. This is probably the case for Clue users. Good thing our app has a dark background? "Even in modern society, where we are cut off from the rhythms of nature, the cycle of ovulation is influenced by the moon. Studies have shown that peak rates of conception and probably ovulation appear to occur at the full moon or the day before. During the new moon, ovulation and conception rates are decreased overall, and an increased number of women start their menstrual bleeding. Scientific research has documented that the moon rules the flow of fluids (ocean tides as well as individual body fluids) and affects the unconscious mind and dreams.1 The timing of the menstrual cycle, the fertility cycle, and labor also follows the moon-dominated tides of the ocean. Environmental cues such as light, the moon, and the tides play a documented role in regulating women’s menstrual cycles and fertility. In one study of nearly two thousand women with irregular menstrual cycles, more than half of the subjects achieved regular menstrual cycles of twenty-nine days’ length by sleeping with a light on near their beds during the three days around ovulation.2"

@lauren_cucinotta WOW Thank you so much Lauren!!! You are clearly a true witch if you're that synced up! Amazing.🌚
