Also, drier vocal cords during menstruation make it more difficult to control vibrato.”

Your Womb ‘Strangling’ Itself Causes Period Cramps

Period Facts

Period cramps are no joke. They are caused by the uterus contracting to get the uterine lining out of your womb.

Ouchies!

But wait, it gets worse. These powerful contractions trigger the release of chemicals called prostaglandins. Prostaglandins encourage the uterus to contract further. It’s as bad as it feels, folks.

Periods Are Worse in Winter and Cold Environments

“Blood vessels constrict in the cold, reducing blood flow,” GP Sarah Jervis said. “If the blood flow from your period is interrupted, it could increase period pain. It’s also possible that pain receptors are more sensitive in cold weather.”

The most scientifically backed theory about why we yawn has to do with brain temperature regulation. A 2014 study published in the journal Physiology & Behavior looked at the yawning habits of 120 people and found that yawning occurred less during the winter than in summer.

Some Penguins Do It as Part of Their Courtship

Why Do We Yawn?

Adelie penguins use yawning as part of their courtship ritual.

This trait has also been seen among emperor penguins. Researchers have been attempting to discover why these two different species share this trait, despite not sharing a habitat.

Yes, Your Dog Is Catching Your Contagious Yawns

Why Do We Yawn?
Instagram

Dogs, and occasionally cats, often yawn after seeing people yawn and when they feel uncertain. Dogs demonstrate contagious yawning when exposed to human yawning. Dogs are very adept at reading human communication actions, so it is unclear if this phenomenon is rooted in evolutionary history or a result of domestication.

Folks Were Once Superstitious About It

Why Do We Yawn?

Back in the day, people had some pretty wild beliefs about yawning including that it was an evil or good spirit entering or exiting the body. It’s because of the belief that in the Medieval period people would make the sign of the cross over their mouths before, after, and during a yawn.
