The moon has been associated with a wide variety of superstitions across cultures, even if there’s nothing particularly noteworthy about it; far cooler satellites exist right in our solar system. From its use in the occult to dating advice on Instagram, many people believe it to be much more influential in our daily lives than it really is, even if study after study has proven that it’s really not.
Among all the chatter about lunar phases affecting your third dates and the moon being the literal devil, we forget about the real, bizarre effects it has on life on Earth. Many creatures – including us – respond to the lunar cycle in weird ways. While some of them are learned responses over millennia of evolution, we simply have no explanation for the others.
The Menstrual Cycle Mimics The Lunar Cycle
If you spend some time in the crazier parts of the Internet, you’d come to associate the moon with a lot of weird stuff. Of course, a lot of it isn’t based on any scientific evidence—much like most of the Internet – as the moon is nothing but a cold mass of rock in a perpetual orbit around our planet.
Some of those theories, though, may not have been as far-fetched as we thought, as science is gradually finding out. Take the one about the menstrual cycle being in tune with the lunar cycle, which has been a guiding belief for cults throughout history. It could be dismissed as medieval superstition, though there’s quite a bit of scientific evidence backing it. A few studies have found definitive links between the lunar and menstrual cycles. According to one, women also go through increased levels of hormones around the full moon.
While we’re not sure why that could be, we can refer to some experts guesses. Charles Darwin believed that the menstrual cycle – on average – coincides with the monthly moon cycle for a reason. It backed his then-nascent theory that we first came from the ocean, as this proves that we adjusted our reproductive clocks according to the lunar tides at some point. We’re no experts, but that makes sense to us, as the average span of the menstrual cycle does almost-perfectly coincide with the lunar cycle.
