Why You Should Sleep On A Tough Decision

You’ve probably been told to sleep on it when you have a tough decision to make. It turns out that sleep actually does improve your cognitive skills so that you can make better choices, report researchers at the University of Massachusetts, Amherst.

A group of 54 volunteers were taught to play a game that mimics casino gambling. The group was divided into those who got their usual night’s sleep, came back and played, and those who played later that day without a sleep break.

The “sleepers” ended up having a better understanding of the rules of the game. They also had the greatest winnings: They won four times more often than those who played without sleep time.
