Cool question!

Essentially, your nerve endings in the roof of your mouth go into spasm and send signals to the blood vessels in your head, which dilate in response.
Nothing actually freezes, there is no bloodloss and the nerves in the mouth are not sensing the pain.The dilation and increased blood flow causes the pain!

the cold lowers the pressure and in an attempt to equal the brain has pain....i read somewhere if you put cold on your forehead the pain will go away.
one time i ate a bugar.i drank milk it came out of my noise it hurt is that bad.?
A sudden cooling of the soft pallet on the roof of your mouth causes brain freeze. above the soft pallet is a bundle of nerves that send pain signals into your sinus area.
Nerves in the roof of your mouth are numbed, but send the signal to the other end, thus brain freeze.
when was lung cancer dicovered and by who?
The cause is a dilation of blood vessels in the head. The dilation may be caused by a nerve center located above the roof of your mouth -- when this nerve center gets cold, it seems to over-react and tries to heat your brain.
I accidently fell asleep with my acuve 2 hydraclear contacts on. And I got a question?
When the coldness touches the roof of the mouth the blood vessels swell causing a headache. To help, just put your tongue to the roof of your mouth and it will warm it up and stop the pain
• Your brain DOES NOT actually freeze. NO damage is caused by brainfreeze.
• 7-Eleven registered the term "brainfreeze" in 1994 to communicate the painful joy of drinking a frozen Slurpee beverage.
• Brainfreeze is also known as an "Ice Cream Headache", and "Frozen Brain Syndrome"
• Simply put, Brainfreeze occurs when the Slurpee (or anything cold) touches the roof of your mouth, the collection of nerves in the roof of your mouth (called the spheno-palantine ganglion) go into a spasm (a spasm is like a cramp). These nerves tell the brain blood vessels to get bigger or "dilate". When our brain's blood vessels get big, we get headaches.
• So, the best way to avoid getting brainfreeze is to keep the Slurpee from the roof of your mouth.
• The pain of brainfreeze begins a few seconds after the rapid ingestion of cold foods or beverages (such as ice cream or slurpees or yellow snow)and peaks in 30-60 seconds, and can last up to 5 minutes.
• The Phenemenon is further explained in an article by Joseph Hulihan :
• The pain is usually located in the midfrontal area, but can be unilateral in the temporal, frontal, or retro-orbital region.
• It is a stabbing or aching type of pain that recedes 10-20 seconds after its onset. Rarely, it can persist for two to five minutes
• Some Studies suggest that brainfreeze is more common in people who experience migraines. Raskin and Knittle found this to be the case, with brainfreeze occurring in 93% of migraine sufferers and in only 31% of controls
• Other studies found that it's more common in people without migraines. These inconsistencies may be due to differences in subject selection–the subjects of the first study were drawn from a hospital population, whereas the controls in the second were student volunteers.
• Ice cream headache has been studied as an example of referred pain. Experimenting on himself, Smith found that:
• Ipsilateral temporal and orbital pain developed 20-30 seconds later after crushed iced was placed on the palette.
• Bilateral pain occurred when the stimulus was applied in the midline
• The headache could be elicited only in hot weather
• Attempts to reproduce the pain during the winter were unsuccessful, even with use of a cold stimulus of the same temperature.
• Bird et al found a similar relation with respect to site of application of the cold substance and ipsilateral occurrence of the resultant pain Some of their subjects also experienced an associated toothache.
• Raskin has suggested that ice cream headache may represent a model of migraine, in that both encompass disordered thresholds to sensory stimuli.
• No treatment is usually required, and sufferers rarely seek medical attention.
It has been reported that the pain can be relieved by moving the tongue to the roof of the mouth, which will cause greater warmth in the region; it is also believed that the pain can be relieved by slowly sipping room temperature water. Laying the head to the side may also provide relief. The pain may be avoided in the first place simply by eating the cold food or beverage more slowly.
Just wanted to say that the brain doesn't "feel" anything. As in, it doesn't contain the kinds of nerve fibers that sense pain, pressure, hot or cold.
And agree with the above postings about the upper palate nerves sending signals.
why is your belly button fluff the same colour as your socks and not of your tee shirt?
wen eating or drinking cold stuff for a prolonged period of time our blood drops in temperature ;blood going up to the brain will be colder and unwelcome by our brain giving us a sensation of pain.
• Some people actually enjoy brainfreeze. I've been told that it can take away a headache.
• Believe it or not, but some people also find it orgasmic... seriously.
Tips for alleviating brainfreeze
• To relieve the pain of brainfreeze, try pressing your tongue onto the roof of your mouth. For some reason, this works
• Try Holding your breath during a brainfreeze, For some reason, this makes it go away faster.
• Try taking a sip or two of a warm beverage, such as hot water, hot chocolate, or even coffee, when the brainfreeze hits. This seems to get rid of the pain quickly for some people.
• A good cure for really bad brain freezes: Close your eyes and press your fingers GENTLY on your eyes so that your fingertips are resting between your eyeball and browbone. Breathe deeply. Wait calmly for the brainfreeze to pass.
• Pinch your nose with your thumb and forefinger. At the same time try blowing through your nose (not too hard) and mouth (with mouth closed). Allow a little air to escape from your nose/and or mouth. Keep the pressure up by continuing to blow.
• Breath in through the mouth and out through the nose. The Idea is that the air gets heated by the body on the way in and helps to warm the palette (at the back of the mouth) on the way out, thereby shortening the duration of the freeze.
