40 Older People Needed Less Sleep ？老年人要睡得少 ？

①The popular notion that older people need less sleep than youngster adults is a myth,scientists said yesterday.

②While elderly people tend to sleep for fewer hours than they did when they were younger,this has a negative effect on their brain‘s performance and they would benefit from getting more,according to research.

③Sean Drummond,a psychiatrist at the University of California,San Diego,said that older people are more likely to suffer from broken sleep,while youngster people are better at sleeping efficiency straight through the night.

④More sleep in old age,however,is associated will better health,and most older people would feel better and more alert if they slept for longer periods,he said.

⑤"The ability to sleep in one chunk overnight goes down as we age but the amount of sleep we need to function well does not change,"Dr.Drummond told the American Association for the Advancement of Science conference in San Diego.

⑥"It‘s definitely a myth that older people need less sleep.The more healthy an older adults is,the more they sleep like they did when they were younger.Our data suggests that older adults would benefit from continuing to get as much as they did in their 30s.That‘s different from person to person,but the amount of sleep we had at 35 is probably the same amount as we need at 75."
