The alarm goes off and your eyes open. What's the first thing you do? If you're like most people, you have a good stretch. This instinctual action is called pandiculation, and it does wonders for rebooting your body.
Pandiculation comes from the Latin word pandere, meaning "to stretch." Humans aren't the only animals to engage in pandiculation. If you have a dog or cat, you've likely noticed their full-body stretch in the morning or after a nap. They'll arch their backs, stretch out their front legs and let out a big yawn. It can be pretty cute, but it also serves an important biological function.
