People get cramps during menstruation because their muscles are working hard to help the blood leave the body.
Imagine your uterus is like a little house with doors that open and close. When it's time for the blood to come out, those doors need to open wide, and that takes some effort! The muscles in the uterus tighten up, like when you squeeze a sponge really hard to get water out of it.
Sometimes, these muscles get too tight and start to hurt. That's what we call cramps, it feels like someone is gently squeezing your belly from the inside.
What Makes Cramps Feel Worse
Cramps can feel worse if there’s not enough oxygen getting to the muscle. It’s like when you run really fast and then feel a burn in your legs, that's because your muscles are working hard without enough oxygen. The same thing happens in the uterus, which makes the cramp feeling stronger.
So, during menstruation, your body is doing a lot of work behind the scenes to help the blood leave, and sometimes it feels like a little squeeze on the inside, that’s your cramp!
