【解析】

Sleep requirements differ from one person to the next. Primary school children need about nine to 10 hours. Studies show that increasing your child’s sleep by as little as half an hour can greatly improve school performance. Teenagers need about nine to 10 hours too. Teenagers have an increased sleep requirement at the time when social activities cause a reduction in sleep time. Adults need about eight hours. We tend to need less sleep as we age, but if you have to deal with pressure during the day, aim to get more sleep. Staying awake for 24 hours causes bad effects to your hands and eyes, which are similar to having a blood alcohol content of 0.1. Even just losing two hours of the recommended eight hours of sleep can lead to poor judgment. This is why lack of sleep contributes to road accidents and work injuries.

Men sleep an average of 30 minutes less than women. Overweight patients sleep less than those with normal weights. The fatter people sleep about 1.8 hours a week less than those with normal weights. So people who sleep less tend to be fat, and experts say it’s time to find out if more sleep will fight fatness.
