睡眠不足

 

You're Clumsier Than Usual

 

反应迟钝

 

 

First you knock the alarm clock off the dresser,then you spill the milk as you're pouring your cereal, then you stub your toe on the way out the door -- you've become a klutz overnight.

 

Researchers don't know exactly why, but sleepy people seem to "have slower and less precise motor skills," Clete Kushida, M.D., Ph.D., director of Stanford University Center for Human Sleep Research told Prevention. Reflexes are dulled, balance and depth perception canbe a little wonky and since you may also have trouble focusing, reaction time can be slowed, meaning you can't quite catch the egg carton before it hits thefloor.
