'Eastern brain' - strange phenomenon but a lot of people have experienced it

Experts have explained why many people are "brain-free" - the cold feeling to the mind when eating ice cream.

A cool ice cream or ice-cold cup is a perfect choice for a beautiful sunny day. However, for many people, eating ice cream makes them " brain-free".

"Eastern brain" sounds dangerous but in fact they are a feeling of sharpening up to the brain when eating cold food .

Back in the past, brainwashing was one of the mysteries dating back to the 19th century. It was first recorded around 1939 and was officially recognized as a headache caused by cold food in 1988 by Hiep. International Headache Association.

By 2013, this phenomenon has been called by the scientific community as "cold-stimulating headache".

"Eastern brain" is actually the feeling of being chilled to the brain when eating cold food.

The first hypothesis of this phenomenon is given to explain the reason "eastern brain" is related to physical problems.

Eastern brain occurs when cold food touches the palate, stimulating the trigeminal nerve.

This is the nerve that controls the sensation around the forehead. That's why when you cause this nerve to suddenly become cold and deep, your pain will often focus on the forehead and temples.

In fact, different nerves cause pain in different areas of the head. For example, toothache will stimulate the lower jaw, causing pain near the middle of the skull.

But with this brainstorming phenomenon, the source of the pain is slightly different than most other pain. It's almost like the reason why limbs are numb from cold.

At this time, the body will put blood into this area to try to help the body return to normal temperature. During this process, your blood vessels will dilate, leading to sharp pains.

Similarly, while the brain is crowded, blood vessels in the brain will expand, transmitting blood to the palate and causing pain. Trigeminal nerve is one of the most important parts of the body. Therefore, if this is the cause, should everyone be hurt?

Yet, only about 40% of Americans, 15% of Danes, 21% of children in Taiwan have this strange phenomenon . Scientists explain that it is possible in these people, nerves Their triplets are less sensitive than others.

In addition, some other researchers have suggested that the brainstorming phenomenon of eating too cold has an intimate relationship with migraine.

The brainstorming phenomenon of eating too cold has a close relationship with migraine.

In 2004, Macit Selekler, a Turkish neurologist, and his colleagues did an experiment. He asked volunteers to put a small block of ice in his mouth.

Experimental results showed that 60% of volunteers felt bitter and 80% of these people had migraine.

In addition, 9,000 teenagers aged 13-15 volunteered to participate in the experiment. And up to 40% of them feel the phenomenon of brain sharpness and 15% of them have confirmed the occurrence of migraine.

This makes scientists think that trigeminal nerve also plays an important role in.

But whatever the reason, don't worry too much, just wait for a moment - about 20-30 seconds the brain will go away. The body will return to its normal state, but next time you don't want to experience this feeling, don't eat cold food in a hurry!
