英语课
Ann Pushet Murphy joins us now. This is astonishing! 15 minutes can change a B to an A, and they saw their test scores go up that much by changing the school time to 8:30. Why does it have that dramatic effect?
Well, the main reason is of course now we can look at kids' brains and what's fascinating is that we realize that it's not just they can't pay attention, all the things you wouldn't to eh… the related thing would be, the result of sleep deprivation 1. Their brains are working progress until they're 21 years old. So a lot of learning happens when they're asleep. And so sleep （Ah）deprivation has this exponential effect on learning. (just in the wiring) The University of Virginia said in one of the things that the expert said that I thought was so astounding 2, was it has much more of impact than a lead exposure. In other words sleep deprivation really can impair 3 a kid's learning more than lead exposure. I think, you know, we're worried about drugs and alcohol as parents of teenagers, but we really have to start looking at how much sleep shall are they getting.
Right. And you've mentioned maybe high proactivity has a lot to do with sleep deprivation, too.
Yeah, definitely. Obesity 4, car accidents, there are lots of different occasions.
All of those things. Can we extrapolate this automatically to adults? Any problem?
Well, yes, but we do have similar problems, of course, we do suffer when we don't get enough sleep. But we can make it up a little bit better. And also again our brains are, unfortunately for better or worse, you know we are not gonna be doing a lot more growing when it comes to learning as adults in our sleep, but kids they do a lot of learning when they're asleep.
So that's a profound impact. We'll put it up on the screen, and let everybody just study it and go online to the recommended amount of sleep for a child at different ages out there.
And it is a lot for the teen years I mean, this is weird 5. It's very hard to get the teenagers to get 8.5-9.5 hours of sleep.
Right. But that can make all the difference. Again you're looking at a 15-min margin 6, so imagine what's like to get 9.5.
Yes, yes.
Genius!
Right, exactly. (Right!) But unfortunately, you know after 8th Grade, it really goes down.
You said three quick things about helping 7 a child get to sleep. Darkness, of course, in the room. Slower down. And then no extra caffein. But address "slower down" for me, that is, what does that mean?
Yeah! Well. One of the things that a lot of people think and it's a myth, and this is true for young children as well, it's you can't tire a kid out and expect them to have a good quality of sleep. So make sure those late night practices are really at a minimum and you don't rough house too much and get the computers and the TV sets out of their rooms. (out of the room)
Thank you. Annie.
