Do you like watching TV or playing games? How many hours do you use your phone a day? We call the time we spend on TV, computers and phones “screen (屏幕) time”.

In a study (研究), scientists (科学家) ask 577, 000 children how much time they spend on screens, schoolwork and sports every day. They find about 68% of them spend more than 2 hours on screens.

Two hours of screen time a day is bad for children’s health. The study shows harm (伤害) starts after 75 minutes of screen time for girls and 105 minutes for boys. Why is that? “Just because . In our study, 24% of boys spend an hour a day doing sports, but only 14% of girls do that,” Dr. Khan says.

So it is important for students to do sports and balance (平衡) their screen time. Tom has a “three-time system(系统) for his son Patrick—a “go time” for schoolwork, a “slow time” to play games or talk with friends on the Internet and a “green time” for sports. “We need to get children out and move. They can walk, ride a bike and play football,” he says.
