2) What happens during a brain freeze ?
3) Why do yo get a small head ache from a brain freeze?
4) Can you stop a brain freeze?
5) interesting facts 1) What is a brain freeze? A brain freeze, or sphenopalatine ganglioneuralgia in medical terms,is a small headache usually lasting about half a minute.If you've ever had this,
it probably happened after slurping
up a really cold drink or eating
something cold.Some people say it
feels like a stabbing pain in your
forehead. By: Matthew Morgan 2) What happens during a brain freeze? First, it all starts when some cold food or beverage touches the roof of your mouth (your palate). That sudden temperature change of your palate stimulates your trigeminal nerve to cause rapid dilation and swelling. Your body right now is trying to direct blood to the area and warm it back up. 3) Why do you get a headache during a brain freeze? Next, you start to feel pain. Blood vessels
triggers pain receptors, and increases sensitivity
to further pain, which starts to hurt. The nerves
then send signals to alert the brain the problem.
But the reason you get a headache at your forehead is because your brain is misled from the trigeminal nerve that sends signals to the brain. The pain is in a different location from where you feel it. Can You Stop a Brain Freeze? It's the sudden chill from something cold touching the roof of your mouth for ten seconds, so eating cold food slower will most likely stop it. If you are eating or drinking something cold it helps to have your mouth already cold rather than to allow it to warm up. When you do have a brain freeze though, it helps best to warm up your palate with your tongue and relive pain. Also try not to let your straw reach the top of your mouth. Interesting Facts: First, only 1/3 of people experience a brain freeze after eating something cold.

Second, a brain freeze is most likely to happen in summer then winter because of temperature difference in your mouth.

Third, anything you eat quick can give you a headache. You are most likely to get one when the food is hot and
you're cold or when the food is cold
and you're hot.
