Ever drunk an ice-cold smoothie only to get a throbbing headache?

Congrats, you just had a brain freeze!

How does it work?

Basically, on a hot day, you are probably dying for a cold cold drink. but when u take a sip from the freezing drink, you subject the nerves at the roof of your mouth to extreme coldness. This results in your nerves sending signals to your brain that you are freezing (when u really aren’t) and your brain then reacts by heating itself up (to protect itself from being frozen).

When that happens, your brain is actually overheating itself without realising it. Hence, you get a brain freeze!

So if you ever want to avoid a brain freeze, try drinking ur drink such that it does not touch the roof of your mouth so as to avoid the nerves clustered there going haywire and sending wrong signals to your brain! =)
