Personal Growth Series: Dr. William Dement on Healthy Sleep and Optimal Perfo...

thanks very informative!

I think this talk has been juxtaposed with other talks that delivered far more useful information, and consequently I feel like I've totally wasted an hour. If you want to find ways to address your sleep problems the only thing you will get from this video is:

(A)sleep debt accumulates and you have to eliminate by getting more than usual (B)you have body clock that dictates sleep patterns, change it by using bright light therapy (C) sleep is crucial to health, along with nutrition and fitness.

Did anyone watch it all?

[lilmoony717]

@TheAshma haha I'm going to try to watch it all. It's for class anyways.

'some time in the afternoon you start to feel more alert' ... that's me atm :S

[ryran]

I'd give the Professor a "C-" for presentation. Took me three days to finish watching this. That said, I give him an "A+" for some VITAL information. I learned so much, yet I feel it's just the tip of the iceberg. I'm looking into his book now....

[sweeperbart]

I don't know about his presentation style. I'm bored. Sorry professor.

I like to learn more about sleepwalking. I'm 30 years old, and have been doing it regularly all my life.

[wickedtothemisty]

I have started sleeping from just after sunset (when it goes dark) to waking at just after sunrise (about an hour or so after sun appears over horizon). Insomniacs take note, Dement does not mention it but waking about 4 hours into this sleep for 1-3 hours and then sleeping for another 4 or so is normal when no artificial light is in the equation and may actually be the sleep cycle that we SHOULD be doing, and all of our ancestors were doing before the advent of the light bulb. :-)

This lecture will definitely take more than an hour to go through because you need to stop and read to get the full benefit of the information provided. But still, its a great, informative lecture from a funny man.

[Burdell22000]

every day I almost sleep

[stigbigstoorm]

As good a talk as I had expected, I bought the book Promise of Sleep in 2000 saw a sleep specialist afterwards and had a polysomnograph done. I was tired all the time because one of the causes was Periodic Limb Movement.

Some interesting facts.

I'm really surprised that contrary to "common wisdom" a big meal doesn't make you sleepy according to him.

[Luke123098]

Yeah i've had that "Natural High" before from staying up for too long, was very funny.. lol

[BrunoM130]

He makes me fall asleep! Thanks Dr.!

About bright light: how bright is bright? Is a laptop screen in the evening enough to mess up your biological clock? If so, what if you reduce the brightness? Has anyone quantified this?

I'm trying a little experiment now, where I set my laptop screen brightness to 15% (less gives me a head ache) and allow very little ambient light. But it would be nice if someone's already done that and can tell me the result.

[Provoost]

How about Google Snore?

What if people could turn on their microphone at night and upload the sound to Google. Google would then tell you how much you snore (if your don't have a partner to tell you) and if it sounds like a breathing disorder. Perhaps it can even hear how much you actually sleep and keep a nice record of that.

Provided no human would ever listen to it, I wouldn't be too uncomfortable with it.

[coastwalker]

Very useful, been building up my bank for just over a week and it works!

[enos76]

Quite interesting but... at 38:10 he talked about experiments involving the removal of parts of live animals' brains :-( science progress, it's a pity our hearts can't progress as fast.

[RhamosVhailejh]

That was very informative. Thank you.

[ninelives121]

Don't expect to learn anything from this.

So if you don't get much sleep at night you are liable to fall asleep more? Is this why he's the worlds foremost authority on sleep?

There is plenty to contradict what he says like his claim that eating a large meal doesn't make you tired.

And he tops it off with a joke about masturbation, shouldn't tell that joke that wanker symbol was referring to you.

[someman7]

I sleep almost every day.

[carolmcdouy]
