Hello and welcome to the Nutrition Facts Podcast. I'm your host, Dr. Michael Greger.

Now I know I've made a name for myself and explaining how not to do certain things.

Just look at my books. How not to die in my upcoming book, How Not to Diet.

But what I want to share with you is actually quite positive.

What's the best way to live a healthy life? Here are some answers.

It's time for the Nutrition Facts Grab Bag where we look at the latest science and a whole variety of topics.

First up, the effects of cell phone radiation. While that sounds a little scary,

today we look at the effects that cell phones have on the quality of our sleep.

Sleep is crucial to the development of physically and psychologically healthy children,

but a number of factors have been identified as interfering with sufficient sleep,

including the use of electronic media devices. These days most children,

and nearly all adolescents, have at least one such device in their sleep environment

with most used near bedtime, and such use is associated with inadequate sleep quantity and quality

with a resultant excessive daytime sleepiness. So there are calls to minimize device access at bedtime.

But wait a second, not so fast. I mean, which came first? The media use or the sleeping problem?

Are they not sleeping because they're on their phone or are they on their phone because they can't sleep?

Higher media use has been consistently associated with all sorts of sleeping problems.

Is it because they're so caught up, they push back their bed times?

Or does it so kind of key them up that they have trouble falling asleep?

In college A students, it may be more of the reverse.

The not sleeping leading to pulling out their screens instead of just staring at the ceiling.

Though in early childhood, it may be a bit of both.
