If it hasn't happened to you, count yourself as lucky. For many people, eating ice cream or drinking an icy drink too fast can produce a really painful headache. It usually hits in the front of the brain, behind the forehead.
The technical name for this phenomenon is cold-stimulus headache, but people also refer to it as "ice cream headache" or "brain freeze."
The good news is that brain freeze is easy to prevent — just eat more slowly. The other bit of good news is these headaches don't last very long — a minute at the outside.
It's the epic quest of campers everywhere: How do you get the perfectly toasted marshmallow? In our inaugural installment of NPR's Summer Science series, we gave some guidance on the first key ingredient: how to build the campfire. (Later this summer, we'll attempt to answer the vexing question of how to stave off brain freeze.)
Summer living is supposed to be easy — school is out, the days are long, the traffic eases. But it's not all inner tubes and lemonade: Summer can throw us some curveballs, too. How can I avoid sunburn? What can I do to stave off that brain freeze? Why do my s'mores always burn?
Fear not; NPR is here to help. As part of our new Summer Science series, we'll turn to science to tackle these vexing questions, starting with how to build the perfect campfire.
