Early to bed, early to rise, makes a man healthy, wealthy and wise.
This is an old English saying. Have you heard of it before?I mean that we must go to bed early and get up early in the morning. Then we shall be healthy. We shall also be rich (wealthy) and clever (wise).
This is true. The body must have enough sleep to be healthy. Children of young age should have ten hours' sleep every night. Children who do not have enough sleep cannot do their work very well. They will not be wise and they may not become wealthy!
The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.
Exercise also helps the blood(血液) to move around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!
Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later,her eyesight(视力)dropped to 300 degrees. This is serious for such a young child.
Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"
"There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "
Doctors and scientists say children's vision(视觉)is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright(明亮的)LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.
Doctors advise that users should hold their iPads between 40-60 centimeters(厘米)away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.
