Ever felt a sudden stabbing pain in your head after enjoying our delicious ice cream and wondered what on earth that was? Don't worry – it's not Katchi Ice Cream's fault, and there's nothing wrong with your brain either. It's called brain freeze. Here we explain what it actually is and why you don't need to worry about it.
Why do you get brain freeze?
Brain freeze, also known as an ice cream headache or cold-stimulus headache, happens when cold food or drinks – like our beloved Katchi ice cream – rapidly cool down your mouth or throat. This sudden change in temperature causes a stabbing headache, the most typical symptom.
The science behind it: why does it hurt so much?
1. The rapid change in temperature
When cold food or drinks touch the roof of your mouth, they cool the tissue near the nerve endings. The trigeminal nerve, the largest nerve in the face, is particularly affected. It's responsible for sensations in the face and registers the sudden cooling.
2. Blood vessels widen
To make up for the abrupt cooling, the blood vessels nearby quickly widen to bring in warmth. This sudden widening and narrowing of the vessels confuses the nervous system.
3. The pain is passed on
The trigeminal nerve interprets the rapid change as a pain signal and passes it on to the brain. The brain, not knowing exactly where the signal comes from, reads it as pain in the head. The pain is temporary and usually disappears within a few seconds to minutes.
What does an ice cream headache feel like?
Brain freeze pain is:
- Stabbing or throbbing: it often feels like a knife in the forehead.
- Short but intense: the pain usually lasts only 20–60 seconds, but can last up to two minutes.
- Located in the forehead: you usually feel it in the forehead or between the eyes.
As fierce as the pain can be, it's harmless. It normally disappears as quickly as it came.
How many people get ice cream headaches?
Brain freeze is a common phenomenon that most people experience at least once in their lives. Studies estimate that around 30–40% of people get it regularly, especially when they eat or drink cold things quickly. Children and teenagers are more prone to it, because their nerves react more sensitively to temperature changes. Then again, that might also have something to do with the fact that lots of kids can hardly contain their excitement about their ice cream… ;-)
Interestingly, ice cream headaches are more common in people who suffer from migraines. It's thought that their reaction to cold is amplified because they're already prone to migraines.
Who's especially prone to it?
Brain freeze doesn't affect everyone equally.
A few factors can influence how sensitive you are:
- Age: children and teenagers are often more prone to brain freeze than adults, probably because their nervous system is more sensitive.
- Migraine sufferers: studies show that people prone to migraines get brain freeze more often and more intensely.
- Sensitivity to cold: people who are generally sensitive to cold may also be more prone to it.
Which nerve causes the stabbing pain?
The key nerve in brain freeze is the trigeminal nerve. This large facial nerve sends sensory information from different parts of the face to the brain. Among other things, it controls the muscles we need for chewing.
Here, the trigeminal nerve registers the sudden cooling in your mouth and sends pain signals. Because the brain can't tell exactly where the signal comes from, and the trigeminal nerve also covers the forehead, the pain is "referred" to the forehead – even though the actual cause is in the roof of your mouth.
What helps against brain freeze?
When an ice cream headache strikes, there are a few simple tricks to get rid of it fast:
Warm up the roof of your mouth: press your tongue firmly against it. The warmth of your tongue helps even out the temperature.
Drink something warm: a sip of lukewarm water can calm the affected blood vessels.
Breathe through your nose: that warms up your mouth faster.
Change your head position: tilting your head forwards or backwards often helps.
How can I avoid brain freeze?
Since brain freeze is caused by your mouth cooling down suddenly, the key is to warm the affected spot back up quickly – or ideally to prevent that sudden cooling in the first place. Here are the best strategies:
Take it slowly: avoid swallowing large amounts of ice cream or cold drinks in one go.
Protect the roof of your mouth: try to keep cold food in your mouth a little longer before it touches the roof of your mouth, or steer it somewhere else with your tongue.
Temperature of food or drinks: you could let very cold food or drinks warm up a little before you have them. But please don't do that with our Katchi ice cream! It only keeps its creamy, delicious texture if you don't let it melt. So our tip: eat a little more slowly and don't swallow the ice cream straight away.
Is brain freeze dangerous?
No, brain freeze is completely harmless. As intense as the pain can be, it's temporary and doesn't cause any lasting damage. It usually disappears within seconds or a few minutes. Brain freeze is simply your body's way of warning you about extreme cold.
However, for people prone to migraines, brain freeze can trigger a migraine attack. If that's you, take a bit more care with cold food and drinks. Don't worry, you can still enjoy them – just not quite so fast. That tip applies to people without migraines too, of course.
Conclusion: brain freeze – harmless but fascinating
Brain freeze may be unpleasant, but it's a fascinating example of how our body reacts to extreme changes in temperature. The combination of sudden cooling, blood vessels rapidly widening and narrowing, and the role of the trigeminal nerve makes the ice cream headache an intriguing phenomenon – and an unwanted companion on hot summer days with cold desserts. The good news: even if you can't avoid it forever, a small change in how you eat and drink can help prevent it! So nothing stands in the way of enjoying a delicious Katchi ice cream pain-free this summer!
Remember this next time brain freeze gets you: it's only a small price to pay for the joy of ice cream. And with the right tricks you'll quickly forget it and carry on enjoying your dessert!
Curious facts about brain freeze
And of course we want to finish with a bit of fun – so here are a few (curious) facts about brain freeze:
There's a Guinness World Record: one competitor managed to drink three large slushies in under a minute – without any visible signs of brain freeze.
Brain freeze can help migraine research: because it triggers similar mechanisms in the brain to migraine, researchers use it to develop possible migraine treatments.
The medical name is a real tongue-twister: brain freeze is called sphenopalatine ganglioneuralgia – meaning a nerve in the roof of the mouth is irritated by cold.
It's not limited to ice cream: brain freeze can also be triggered by extremely cold air or by breathing in cold mist.
Animals can get it too: dogs and cats that eat cold treats show similar signs of discomfort.
We hope we've managed to explain brain freeze and given you some useful tips so your next ice cream is completely headache-free. See you soon – at Katchi Ice Cream!
