U.S. scientists have proved that the ice cream headache that affects people when eating food or drinks, frozen happen as a result of a sudden change in the flow of blood to the brain. This may help to detect in the treatment of other types of severe headaches, such as migraine headaches (migraine), which causes episodes of acute pain for a lot of people.
The researchers in this study, the follow-up blood flow to the brain when 13 healthy adults when eating ice water, through the absorbent focused toward the roof of the mouth to make a cooler brain.
The results concluded that these seizures are caused by a sudden increase in blood flow within the anterior cerebellar artery. The brain freeze disappears again when The artery contracts.
The study author George Sirador, from the Faculty of Medicine at Harvard University to stretch rapidly artery cerebellar front, and subsequent constriction fast, it may be a kind of self-defense to the brain, and added that the latter is one of the main organs of the body and needs to work all the time. And shows great sensitivity to temperature, this expansion may occur in the blood vessels, for the transfer of warm blood into tissues to ensure the survival of brain warm.
Furthermore, he noted that the skull is building closed and the sudden rush of blood could increase the pressure causing pain in the head. While contraction after the artery may also be a way to reduce the pressure inside the brain, before reaching a critical stage.
He concluded by saying that changes in blood flow that we see in the cooler brain can also be linked to migraines and other types of headaches. For this to find ways to control the flow of blood to the brain may provide new treatments for headaches.
