Intense shivering after the baby is born?
It's the postpartum chills.
You shiver like you're naked at the north pole. Your teeth chatter. But you're not cold. Warm blankets and hot tea don't help.
Why does it happen? It isn't fully understood, but theories include fluid loss, heat loss, hormonal changes.
It's the most annoying thing, and you can't stop it. Or can you?
Generally, it is self-limiting and you can just ride it out. Duration varies from a few minutes to a half an hour. But if you can't stand it....
Stick out your tongue!
As long as your tongue is out, the shivers stop. Put it back in your mouth, and they resume until the episode is over.
