Hey, here's a slight silver lining for everyone else like me who sleeps for around five or six hours a night. We don't need to be jealous of the people who manage to sleep for 11 straight hours. They're JUST as dumb as we are.
According to a new study, sleeping too much is just as bad as sleeping too little.
The researchers found that people who slept for four or five hours a night would perform on tests like their brains were nine years older. BUT . . . they saw the same effect on people who slept for over 10 hours a night too.
The biggest abilities you lose when you sleep too much or too little are your reasoning and verbal skills.
So it's probably best not to get into a serious argument or negotiation when you're super tired . . . or super well-rested.
