i missed the doctors answer about when is the best time to exercise. Also, how did he treat the question from dan who runs alot but only sleeps 5 hrs a nite? is this detrimental over the long term?

brian keeps insisting that "we choose" the behavior, completely discounting everything the guests have said about the controlling circadian rhythms. the reason the kids are "perky" at 10 p.m. is not orneriness or greed to watch "The Daily Show" but their teenage body clocks.

No I'M sorry....If increased homework to meet school testing requirements ultimately affects how much sleep a child can get, then it certainly is within topic.

I would like the speaker to comment on the relationship between sleep deprivation, obesity and nursing. I am the mother of a 2 month old and clearly sleep deprived, I am also nursing which requires greater caloric intake - how can this affect my health?

I remember 20 or so years ago being told not to exercise before sleep because the endorphins (whatever the hell they are, sound like aliens from the planet Endorph) are aroused or stirred up and you no longer feel tired because they cause you to feel good. The Dr would say the best time is about 1 hour after you wake up in the morning.

As to Brian's question why we do this (don't set school start times at bio-appropriate times), why do we wait until H.S. to teach foreign languages, despite the well known fact that young children are much more adapt at learning languages???

Duh!

The guests mentioned melatonin, but what about other natural products? Valerian? Triptophan? Do these have any value for insommnia?

Thanks

Sorry, no child left behind, is off topic.

What's a parent to do? I have a 16 year old, she can't fall asleep, even if she goes to bed at 10, until 1/2-1 hr later but needs to wake up at 6 am. With all the homework and activities that kids do they don'at have much time to sleep.

I'm a college senior with sleep problems. I've been running fifty miles a week for a year and a half, but still rarely get more than five hours of sleep. Believe it or not, I sometimes can't sleep even after I run a marathon! How is this possible, and how do I stop it?

Can we work this into "No Child Left Behind"? My kids - first and third grade - are up later than they should be because they have SO MUCH FREAKING HOMEWORK!!!

How does caffeine and energy drinks affect our sleep?

I always feel more tired later in the week, if I drink a lot of coffee earlier and throughout the week.

do naps help?

is there a noticable effect when cultures that have traditionally had siestas as a norm start modernizing and abandon them? would we benefit from adopting siestas as a cultural norm?

Well, loss of sleep causes stupidity, take it from me. I've become very stupid since I now sleep only 3 hours a night or less. So I advise one to correct any problem developing in this area as soon as possible: you know, nip it in the bud.

What is the appropriate time for a 3 year old to go to bed?

I can't call in right now but I have a question... I often get migraines during the night, I'm not sure if it's sinus related or not. I've never been able to figure out why. I often feel like I'm a little wiped out the next day... how do the migraines affect my sleep, or my thinking the next day? and any suggestions on the problem?
