Why do we get Brain freezers when we eat something cold?

The standard medical term for this phenomenon is "ice cream headache"--an expression so clear and comprehensible you know this is a topic science has ignored. Here's pretty much all we know.\n\nIce cream headache occurs most frequently after you've worked up a sweat or during very hot weather. Typically it starts when you cram too much cold stuff into the roof of your mouth. It reaches a peak in 25 to 30 seconds that can last from several seconds to a couple minutes.\n\nMost people feel ice cream headache deep in the front of the head, although if the ice cream gets stuck in the vicinity of your tonsils you may feel the pain behind your ears. Cold farther down the throat produces no headache.\n\nThe cause of ice cream headache is far from clear. One plausible explanation is that the cold causes constriction of blood vessels near the point of contact, which in turn causes the blood to back up painfully inside the head.\n\nIce cream headache occurs in maybe a third of the general population but in over 90 percent of migraine sufferers, who feel it in the same place they get migraines. (Many migraine victims take precautions with frozen desserts for that reason.)\n\nResearchers believe migraine and ice cream headache are physiologically similar, the difference being that migraine sufferers are abnormally sensitive to stimuli the rest of us ignore.\n\nAs for what would happen if you applied the cold continuously, I imagine a migraine sufferer could give you a pretty graphic description. I don't expect it'd be fun.

It is called the energy of activation or activation energy. The bacteria and maybe fungi cannot multiply at the reduced temps so the food will not be attacked by the microbes.Also proteins don't breakdown quickly at lower temps so the food will be fresh when it defrosts

Because all cold air is created in the freezer. The fridge gets cold by leeching off the freezer.  There is only one compressor. Cold air sinks, so it falls into the fridge.\n\nUnits like side by side and bottom freezers need a fan to get the cold to the fridge. A top freezer doesn't.

From personal observation I would say not always.  When ice is frozen for a long time it seems to lose its freshness.  It picks up odors and when defrosted doesn't smell or taste like fresh water. These things would indicate physical changes probably due to evaporation and perhaps osmosis.  Both of these occurrences would produce a change in quantity.

When purchased from a grocery store, frozen vegetables are as nutritious and sometimes more nutritious than fresh fruits and veggies.  The reason is that fresh fruits have been sitting for several days in transit before they reach the store and then usually sit for a few days in your house, that whole time, they are losing nutritional value.  \n\nFrozen veggies are usually packed frozen shortly after being picked and therefore maintain their nutritional value.  Studies have shown this, check out the link below.  \n\nCanned vegetables can have similar nutritional value preservation, but some compounds like vitamin C break down during the heating process in canning.  \n\nFresh fruits have historically been viewed as being most nutritious, and it is true if you grow it yourself, pick and eat.  But if you're heading to a grocery store, head for the frozen foods for nutrition.

Also note that after you eat, you generally feel cold because most of your body's blood is diverted to your stomach to aid in digestion.

no...I think the only way someone can catch a cold by being cold is that the cold weather may slightly lower the immune system so that you are more vulnerable to catch a virus.\n\nHowever, eating ice cream with a cold will not do anything, but the dairy may cause an increase in phlegm production, which would not help your congestion.

No. For humans, this concept is almost impossible. There is nothing in our body that could help us sustain life, when our body's are frozen.\n\nAlso, when frozen, ice crystals develop. As small as they are, all of them do extensive damage to muscles and tissues. This means if you were to be defrosted, you wouldn't nearly be the same. Even without ice crystals, freezing and unfreezing tissue causes damage.\n\nBlood also ices. Nothing can be done to repair that.

I think it is because you body is not functioning at its best when someone is tired.  So what happens is the person's resistance drops and his ability to warm up.  \nHave you ever noticed that after eating you get cold?  It's because your body is working harder to digest the food and the other bodily functions slow down.  That's also why we feel tired after over-eating.

It's just cold water. So your ownly worries are broken teeth, diarrhea, and terminal brain freeze.

The reaction is triggered by the cold substance consumed coming into contact with the roof of the mouth. It irritates nerves in the region (sphenopalatine ganglia), causing them to spasm. These nerves cause the blood vessels in the brain to dilate. When vessels in the brain dilate, a common effect is an acute headache.

Cold items chill the soft palate in your mouth (the flexible area in the roof of your mouth near your throat) and transfer the cold too quickly to the brain. You can usually shorten the brain-freeze effect by pushing your tongue to the roof of your mouth for a couple moments when it occurs.

Because their bodies are actually craving oxygen so since ice has oxygen, it relieves the body's craving for the oxygen, temporarily. Need to see a doctor.

The eyeball can freeze, but the aqueous humor (liquid inside the eye) has a lower freezing point that water. The eye is embedded in the skull, which the body keeps warm even if the rest of the body freezes. At some point, of course, the heart stops and everything freezes if left in the cold long enough.

yeah, it's your body using it's energy to digest the food instead of keeping you at a steady temperature.  espeically happens after i eat a lot.

Brainfreeze is an intense stabbing headache-like pain that occurs after consuming something cold, and it affects about 30 percent of the population\n\nBrainfreeze occurs when anything cold (maybe icecream, slurpee, etc) 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. \n\n*The best way to avoid getting brainfreeze is to keep cold things away from the roof of your mouth.\n\n**If you have one. The best way to relieve the Brainfreeze is to warm up the roof of the mouth. This can be accomplished by pressing your tounge against the roof of your mouth.
