Native Americans and Pilgrims were onto something when they turned to cranberries as an infection fighter. American settlers believed the bitter food could stave off scurvy. But there's more than just Vitamin C in this indigenous berry.
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.
