what causes brain freeze?

Описание: Ever wondered why ice cream sometimes hurts your head? 🍦🧠
That sudden sharp pain is called brain freeze — and it happens when something cold touches the roof of your mouth, causing your blood vessels to tighten and then expand super fast.
Your nerves get confused and send pain signals to your brain — making it feel like it’s your forehead that’s hurting!

So next time you grab an ice cream or cold drink, remember — it’s just your mouth tricking your brain. 😆
