We sympathized for a few seconds then went on with our business. But not too long after Pearl turned to me and said,
” what is a brain freeze?”
I told her that it was when the blood vessels squeeze tight and swell up.
She wanted more though which prompted me to include it in the new HBDs Go to School curriculum on the brain and nervous system ( launching in June) plus write this post.
Brain freezes only last a minute or so but a lot of things happen in that short minute. When something very cold touches your palate ( the roof of your mouth), the cold sensation will trigger nerves that control blood flow to your brain. This trigger will cause blood vessels in your brain to swell up which in turn causes the head to ache – known as the “brain freeze.”
Eating colder foods a little slower may help prevent the brain freeze and allow you to enjoy your food a little more.
Find HBD books on Amazon ( there is always a SALE!)
