The Science Behind Slurpees And ‘Brain Freeze’
So what causes brain freeze, otherwise known simply as sphenopalatine ganglioneuralgia? (Try saying that next time you are drinking a Slurpee.) No, the Slurpee does not actually travel up to your brain, unless you are drinking Slurpees the wrong way. Instead, when a cold substance touches the back your throat, it lowers the temperature around the blood vessels close to the back of the throat, including the internal carotid artery and the anterior cerebral artery that supply much of the brain with blood. In general, the body does not like rapid changes in temperature and has numerous mechanisms to maintain the same temperature. For example, when a part of the body gets cold, blood vessels constrict (or tighten) to conserve the heat in the warm circulating blood. This occurs when you apply ice to an area for a while and the skin turns pale. Conversely, when your body gets too hot, blood vessels dilate (or get wider) so that more heat from the blood is released through the skin. This is why people’s skin looks redder when they exercise. independent of whether they use a spray-on tan.
Thus, when you drink a Slurpee, the blood vessels near the back of your throat first rapidly constrict from the coldness and then dilate when the blood vessels become warmer again. The dilating blood vessels then pull the tissues around the vessels and the brain such as the meninges, triggering the trigeminal nerve (otherwise known as the fifth nerve), which innervates much of your face, including your forehead. Nerves can’t always distinguish the location of the original trigger, a phenomenon called «referred pain.» Referred pain is why people may feel pain on the shoulders or back when the cause of the pain is at the heart (e.g., angina or a heart attack). It is also the reason why you feel the sphenopalatine ganglioneuralgia in your forehead and not the back of your throat. Neuralgia is another word for nerve pain. Ganglion is a collection of nerves. Sphenopalatine describes the location of the ganglion.
As a result, advice to prevent or minimize brain freeze includes:
Can brain freeze. er. I mean. sphenopalatine ganglioneuralgia. be harmful? So far, there’s no evidence of any lasting health impact or other health concerns. It is true that scientific data is limited. Try getting some funding for the following clinical trial: asking 700 subjects to drink Slurpees as quickly as they could, each day for 1,100 days and following what happens to their health. However, there seems to be a lot of informal experimentation with giving cats brain freeze such as:
Could blood vessels constricting and dilating somehow be causing primary headaches? Ferdinand K Hui, MD, assistant professor of radiology at Johns Hopkins University and director, National Capital Region Interventional Stroke, is an expert on blood vessels in the brain and explains, «The pathophysiology and pathomechanisms of headaches as a group remain challenging. While some headaches where there is a clear, treatable cause are thought to be well understood, many classes of headaches, even vascular headaches, do not have absolutely clear mechanisms and are often classified descriptively.» In other words, many common headaches have names based on their symptoms and not their causes. Without an understanding of the causes of primary headaches, most treatments are fairly general and focus on masking the symptoms (e.g., pain relief medications such as Tylenol, aspirin or ibuprofen) or trying to relax (e.g., meditation, sleep or watching continuous loops of cats being fed Slurpees and ice cream).
The medical world doesn’t always pay as much attention to what seems like no more than everyday annoyances and irritations. But sometimes such seemingly trivial health phenomena can be the key to unlocking future treatments for other medical conditions. More research into the relationship between blood vessels and headaches could provide important insights. Who knows, maybe drinking Slurpees can lead to some breakthroughs in the treatment of headaches. within the next seven or eleven years.

Основно-небный Ganglioneuralgia: Руководство по Заморозка мозгов
Вы, наверное, испытали это неприятное ощущение, как правило, называют замораживание мозга, мороженым мозгом или мороженое головной болью. Это ощущение, которое может вызвать кратковременную головная боль длится от нескольких секунд до нескольких минут, может случиться, когда вы едите или пьете что-то холодное, как мороженое или воду со льдом. Медицинский термин для замораживания мозга является основно-небный ganglioneuralgia. Вы также можете услышать это ощущение называют холодной индуцированной головной боли.
Мозг замораживание вызвано основно-небный ganglioneuralgia нервы (SPG), которая представляет собой группа нервов вблизи тройничного нерва в головном мозге. Эти нервы расположены позади носа и нервов, которые также вызывают головную боль. Они разработаны, чтобы быть очень чувствительны к боли, по-видимому, чтобы защитить мозг.
Симптомы включают замораживание мозга резкое и внезапное начало боли в лобной части головы. Это может чувствовать себя как тупая боль или острая боль. Боль может длиться от нескольких секунд до полной минуты или два, в зависимости от того, насколько холодной пищи или жидкости вы потребляли и как быстро вы потребляли его.
Теория исследователей в том, что, когда мозг быстро охлаждают в результате проглатывания очень холодной пищи или жидкости, он изменяет кровоток в головном мозге. Холод переносится с крыши вашего рта нервов головного мозга, и это приводит к какому-либо реакция в мозге.
Исследователи использовали Doppler, который измеряет поток крови, чтобы смотреть на кровеносных сосудах в средних и передних мозговых артериях у 13 взрослых, когда они пили как воду со льдом и воду комнатной температуры. Участники пили ледяную воду через трубочку, прилегающую крышу своего рта, пока они не чувствовали мозг замерзнуть. Затем исследователи измерили сопротивление мозга, частоту сердечных сокращений и артериальное давление у этих участников до, во время и после замораживания мозга.
Они обнаружили, что пить воду со льдом усиливало кровоток в передних мозговых артерий, но не средние кровеносные сосуды. Ледяная вода также вызывает повышенное сопротивление в головном мозге. С этими результатами, исследователи пришли к выводу, что боль замораживания мозга на самом деле вызвана увеличением кровотоком и сопротивлением в кровеносных сосудах головного мозга. Так что, если вы испытываете замораживание мозга, вы могли бы быть на самом деле чувствуют кровеносные сосуды вашего мозга, реагирующие на холод. Исследуемая группа была небольшой, поэтому необходимы дополнительные исследования, чтобы понять причину этого ощущения.
