The phrase, "The early bird catches the worm" may be true. It means people who wake early get more done than people who don't. Another saying is former U.S. President Benjamin Franklin. He said: "Early to bed, early to rise makes a man healthy, wealthy, and wise." Scientists have found that people who go to bed 11pm may do better life than people who sleep 2:30am. The researchers are Birmingham's Centre for Human Brain Health in the U.K. Their research showed that people who slept and rose early (early birds) had an advantage people who slept and woke late (night owls). There were differences the brain function early birds and night owls.
The scientists tested 38 people their research. The people answered questionnaires their sleeping pattern and when they felt tired the day. They were then put into an early bird or night owl group based their answers. All of the people had MRI scans their brain and did different tests the day. The early birds said they felt less sleepy and were able to do the tests quicker than the night owls. The researchers said there were big differences the two groups. The researchers said: "Night owls school have to get up earlier, then they go work and they have to get up earlier, so they're constantly having to fight their preferences and natural rhythms."
