Time for "The Shoutout."
Health experts recommend that teenagers should get at least how many hours of sleep every night? Wake up!
Is it five, six, seven and a half or nine hours?
You've got three seconds, go!
To function their best, experts say teenagers need at least nine hours of sleep every night.
That's your answer and that's your "Shoutout."
But you don't.
亚博国际娱乐首页登录亚博体育app安全吗www.yabovip10.con A number of surveys have found that a relatively small percentage of teenagers, between 13 and 15 percent, are getting eight and a half to nine hours of sleep every night.
Most get less.
That's not good for your grades, your athletic performance, how you look and feel.
So, what's keeping all of us up at night?
Dhani Jones helps us the light.
Since their introduction, electric lights have helped up live, work and play in what used to be the dark.
But is all of this light a good thing?
Or is it actually causing us to lose sleep?
And to be less productive?
We'd have to be more productive, we should actually turn off the lights.
Before gas lamps and electric lights people used to work according to the sunlight.
When the sun was up, people would toil away, but when the sun set, the work day was pretty much done.
Answer, the light bulb.
Before we knew it, lights were hanging from the factory ceilings.
And we can work around the clock.
You would think this would mean we could get more work done.
But new studies have shown that artificial light actually disrupts something called the Circadean cycle.
Meaning we'd be getting less sleep.
So I talked to a sleep doctor to find out why.
Here we are with Dr. Bazil from New York Presbyterian Hospital, Columbia University.
You know, doc, what's, preventing us from getting enough sleep?
I think phones are the biggest problem that's new.
So, your work is right there, your email is right there.
People can text you night and day.
Another thing is, your phones and computers emit light, predominantly blue light and we think that light can also interfere with your ability to sleep.
