Why does skin burn in the sun? Why do we get headaches if we slurp a milkshake too fast? NPR's science correspondent Joe Palca tackles the most vexing summertime questions in stories airing on Morning Edition through the end of August.
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.
