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