The weekend (周末) is here! You can sleep longer and get up later than usual. But is it a good thing to sleep longer during (在……期间) weekends?

Scientists from the United States said this habit (习惯) is bad for your health and can make you put on weight (增加体重).

According to sleep expert (专家) Vsevolod Polotsky, sleeping longer during weekends isn’t good for you. You might feel like you’re catching up on (弥补) sleep. But if you still don’t sleep enough during weekdays (工作日) , you will feel hungry more often. You might eat more and put on some weight. Also, sleeping more during weekends can change your biological clock (生物钟). If you get up late on the weekend, you might eat breakfast, lunch and dinner later than usual. Eating later in the day can also make you put on weight. So get up early on weekends!
