Today, I was talking with a coworker and I was surprised to see that she strongly believe that:

  • When the moon is closer to the earth, hair grows faster.

  • The moon influences when a woman (or person with a uterus) will have their period.

  • Pregnant people are more likely to give birth when the moon is full.

Is there any truth to all of this?

Edit: Here are some websites who support those claims:

If this is considered to be multiple questions, I am most interested in the one about the period.

    @NuclearWang I haded a link about women period. I will try to find another about hair growing faster. But, in the meantime, is this link good enough?

  • Those are fairly common myths in Brazil and south america overall. It falls on that "a bunch of people believe in this wives tale" area.

  • The one about more babies being born on the full moon is very common. A quick Google search yields dozens of maternity sites with an article on the subject (which pretty much all say it doesn't work like that). It's notable enough that even HowStuffWorks has an article on the subject.

  • The one about more babies being born on the full moon also has an answer here.
