Sleeping is something all of us do every day, but exactly what happens to us when we sleep isn’t completely understood. On today’s edition of Please Explain, we’re looking into why we sleep, why we sometimes can’t sleep, and why many of us aren’t sleeping enough. Dr. Allan Pack, Chief of the Division of Sleep Medicine and Professor of Medicine at the University of Pennsylvania, and Dr. Michel Cramer Bornemann, Co-Director of the Minnesota Regional Sleep Disorders Center at Hennepin County Medical Center in Minneapolis, join us.

A program on sleep and NOTHING on jet lag? How can that be?
Marielle, yr welcome, and good luck. To Chris who asked about ambien, I loved it the first few years, laughing at the stories of night-cooking and amnesia, until I was cooking and eating my own second dinners in the middle of the night, waking up to some fantastic kitchen scenes in the morning. Funny no more! Terrifying, really.
I just tuned in. Has anyone mentioned the recent airline story: an overflight of 150 miles with 149 passengers, where the pilots seemingly were unaware of where they were?
FYI, in my experience the siesta is more of a break than a nap, and it follows the biggest meal of the day, lunch. Dinners are definitely eaten later in Spain, but they tend to be lighter meals than the dinners we eat here.
What is your opinion of using a sleeping pill(Ambien) every night.
Wait a minute
the tradition in Spain with siesta is also big meal in the middle of teh day and lighter meal later
I have a few questions...
1) No matter when I wake up, usually around 11:30pm my brain shuts off and I fall asleep is that normal?
2) Most nights, I sleep well for about 4-5 hours, then I usually wake up every 30min to an hour before the alarm goes off. Am I ignoring my natual clock, or just worrying too much?
3) Ever since I have been a child, I've needed a fan on for the white noise to sleep. Of course if I have to sleep with out one, I can, but in ideal circumstances, I need it (every small noise really bugs me). Is that just all in my head?
How legitimate is the practice of 'Lucid Dreaming'? As in the Richard Linklater movie, "Waking Life."

and grumpy from b'klyn[16], i read gawker too, and sometimes i can't contribute, but actually only about 10% of listeners do. if you're listening for free, like i have to this year because of an incredibly tight budget, quit yer' bellyaching.
I have a tendency to get sleepy after I eat a meal at night (this only happens at night). Sometimes I will also fall asleep if I watch a movie on TV after a meal. This never happens to my husband.
Any thoughts?
PS. I don't feel tired during the day
Is it true that one does not sleep more than one needs?
The French eat quite late, right before bed. Is that recommended? And how big a meal would be okay?
Years ago I heard or read that if you're not asleep in 20 minutes, you should simply get up. Do your guests have an opinion on this assertion?
I have a 14month old and I went back to work when he was just 12 weeks old and still waking up multiple times a night. I averaged about 5-6 hours of interrupted sleep per night total when he was a newborn and still managed to function just fine. I am still nursing him and even now my need for sleep seems diminished from what it was before I got pregnant.
What (if any) hormone changes take place in a mother than allow her to function with little to no sleep??
I too love books on tape at bedtime - this is sometimes very helpful, but not always . . .
I really do love WNYC and I like Leonard Lopate. But just now the woman who accompanied Leonard during the pledge drive plug asked, "How can people listen to WNYC every day and not contribute?"
The answer is:

Sorry.
I've used books on tape to relax. Don't get anything too stimulating...just slow stories, history, or memoirs. It's always upsetting when everyone is sleeping but me, and this works.
Dear Mary from Fort Greene,
Thank you so much for the recommendation. I was just going to ask how you managed to get "clean" of Ambien!
i read an article at cnn.com awhile ago [of course i can't find it again] about how some people can get really tired,, going towards sleep, but they have a mutated gene that causes them to become more focused, mindful, i guess. is this what allows me to work in a focused manner while my body feels like it's asleep, only using my hands and whatever my brain is doing? totally screws up my biorhythms, BTW.
Marielle, don't despair. Read "Say Good Night to Insomnia" by Gregg Jacobs. It had changed my life (I am not being paid to say this)!
Why are some ppl late sleepers (I'll sleep til noon if I didn't have an alarm) and some ppl wake at like 6AM w/out an alarm?!
If short afternoon naps will make workers more focused and productive in the afternoon, I want to take those study results to every job I have. Can you point me to these study results?
After 6 years of taking Ambien, I finally weaned off of it this month because I read a book about sleep, which confusingly, states the opposite of what these guests are saying.
I read the other day that teenagers bodies do not produce a needed harmone/chemical that induces sleep until later in the evening. Can you comment on this.
As we get older (and my friends and I are in our 60s), we always say we don't need as much sleep as younger people. And we all seem to wake every couple of hours and never seem to get an interrupted 6, 7 or 8 hours of sleep. Does age have any bearing on sleep?
I also grind my teeth!
Will afternoon naps help me function better at work in the afternoon, brain power and focus-wise? My body tells me so. But bosses don't always like this.
Please advise. Thx.
ps - i <3 wnyc am!
why do people grind their teeth?
Why would a postmenopausal woman be awakened often abotu 4 AM - not night-swatty but just in need of a cool-down. Is it normal to wake up in the night and then go right back to sleep, within 5 minutes?
I've had trouble sleeping and tried everything- I have learned the following: keep head raised for breathing. Try to breathe through nose not mouth, meridian tapping for worries before sleeping, socks, sleep mask. There was a painter named Catlin (represented in the Smithsonian) who observed all the native tribes in the Americas in the 1800s and has interesting things to say about sleep positions. http://web.me.com/nancychenderson/iWeb/Site%202/Long%20Version%20Catlin%20Article%20%28PDF%29.html
I've suffered from insomnia for literally my whole life, even as a child. I'm 41 years old now and assume it will only get worse as I get older. I've tried every non-pharmacological suggestion I've ever heard, but none has ever worked. I either have to take an Ambien CR or I don't sleep. I will be very interested to hear this interview.
Why do humans feel the need to nap? How does napping affect sleeping?
How do sleeping pills work?
(Have you noticed I'm posting this at four in the morning?)
