|Going to bed early is better for us
People say: "The early bird catches the worm." It means people who wake up early do many things. U.S. President Benjamin Franklin said: "Early to bed, early to rise makes a man healthy, wealthy, and wise." These sayings may be true. Scientists in the U.K. found that people who go to bed before 11pm may do better in life. They added that people who sleep and wake up early (early birds) have an advantage over people who sleep and wake up late (night owls). They found differences in the brain function of early birds and night owls.
The scientists tested 38 people. The people answered questionnaires about their sleep and when they felt tired. They were then put into an early bird or night owl group. All of the people had MRI brain scans and did tests throughout the day. The early birds said they felt less sleepy. They did the tests quicker than the night owls. There were big differences between the two groups. The researchers said night owls have to get up early for school and work. They are always fighting against wanting to sleep late and their natural rhythm.
