Period pain happens mostly because of substances called prostaglandins, Gunter explained in the post. They’re released from the lining of the uterus and make it contract. And during these period contractions, pressure on the uterus can be just as high as it is during the “pushing” stage of labor, she added. “So if you need an analogy to describe period pain,” Gunter wrote, “use labor or cutting your finger off without an anesthetic.”
If you like this sort of thing may I suggest Dan Bell’s Dead Mall Series where he walks around and films (mostly) old and abandoned shopping malls while giving trivia about why the places are abandoned. It’s extremely fascinating and relaxing.
