Um, I'm no scientist or expert, but from my own experience and as someone who grew up in El Salvador, in a farm in the country side, it is not surprising to me that physical activity throughout the day can definitely help you sleep because you're actually TIRED from so much activity. Also, I think that being physically tired and being hungry because you're physically tired make food taste so much better ... food that is, of course, organically grown and is made from scratch.

OMG...Exercise is good for you?

Wait... tiring yourself out will help you sleep? Where would I be without you, media?

I run every da.... Zzzzzzzzzzzzzzzzzzzz

Doesn't anyone edit these articles before they appear here?

Our bedroom is too small to run around in. So I'll have to pass on that!

I believe that Michael Jackson got lots of exercise from rehearing  "This is It". must

not of got any fresh air with it to make him sleep?? 

running is great if you have your original knees but then running for about 30 years wrecked my knees and now I can't run....get on your bikes folks

When I was growing up I was in constant motion. I got done, ate dinner and after a certain time, it was bedtime. I liked to read before I went to bed, so I was always hearing from my mom.

Once I hit adulthood, the constant motion came to a grinding halt. I kept eating the same amount and soon I was gaining weight. I was working, so the only thing I could do was walk a lot. I still read before bed and slept good.

At 29 I had my daughter. That was the first inkling that all was not going to be good in the sleep department. I learned there were days when things just piled on me and my response was to do power walking. That got rid of the anxiety and I could sleep.

Somewhere in my 40s I found out I am a Hunter GenoType, which means I hum along on adrenaline and if I can discharge it a little at a time, then I have more. If I get into a funk like I am now with looking for work and not finding it, I have a tendency to turn into a sofa spud. Little things overwhelm me and I can't function, much less sleep.

Now at 50, I have Lupus and the kidney damage that goes with it. On days I drink a little too much water, I wake up around three hours after I hit the hay splashing. I have candida. When my blood sugar drops, I wake up. I have seasonal affective disorder. Too much light, I can't sleep. I am going through menopause. Not enough progesterone, I can't sleep. I am allergic to cow's milk so I have a hard time getting enough calcium. I tried taking calcium citrate. My damaged kidneys let it all go through, so I wake up with leg and foot cramps.

On nights I do sleep good, I thank God and hope it's enough to cover the 2.5 hours I got the night before.

I used to be a size three/four. I am afraid to see what I am now. As soon as the temperature drops, I will be back out walking four, five or six miles a day hopefully away from the people that think I need to ride in their vehicle.

I am a morning person. Lately, I have found myself more energized before I go to bed than when I wake up in the morning. But, if I do lifting and carrying and don't wear myself out, I can do that several days in a row. Then I feel good all day long and sleep good at night.

I believe there are a few reasons why running helps you sleep. I started running a couple of years ago and I now sleep like a baby. I attribute my succesful nights of sleep to not only making your body tired but also as you run you strengthen your cardiovascular system. This in turn helps you breath better at night. The significant other also noticed I don't snore as much. I also feel like a have a much deeper and fuller sleep. I don't wake up tired or groggy. I recommend running for anyone with these problems.

And people wonder why Americans seem to be more dumb than their European counterparts?!? I'm fairly certain I lost no less than 3 IQ points while reading this stupid story.

I've tried all of the suggestions in the article but I still do not sleep well.

Not everyone is supposed to get eight hours of sleep a night. I know people that have gotten by on two or three for decades.

Not everyone is 98.6 degrees, either. I am under unless I am running a fever over 100.

All I know is when I get my heart rate up and keep it up for at least 30 minutes, I sleep much better. If someone is the bringer of bad news too late for me to do any exercising, I end up pulling an all-nighter. No point trying to sleep with all that adrenaline flowing through my veins. I stay up and do some good thinking.

I have known this for over twenty years. I could have told them and saved money. What helps is aerobics, weight training, and no junk food.

Wow, a study that deduced physical exercise can help fight insomnia? Only in America...

sleep comes to you when you are tired from a day's work no matter what kind of work, sleep comes when you are free of worry about what you did to yourself and others in a days time.

well, duh....

I ran 5 miles at 7pm last nite couldn't sleep untill 2am when the bars closed & drank10 beers.

I guess I needed the carbs!

Great... now if only my running would stop my husband's snoring I would be in business!

"Try to get a half hour to an half hour of exercise early enough in the day..."

Is that an accurate quote? Is that really what he said?

in the books!duhh

I think the article is a good reminder to folks. Being active, in a healthy way, adds to ones physical balance. Work( physical or mental) is not a contributor to such. Outdoor activity..such as running and walking does make a difference and with the obesity problem in the U.S. it is obvious people need a reminder about the good effects of exercise. It does make a sleep difference and a 'whole' body difference. People need to hear this, even the smarty pants folks that think it is redundent.

If you didn't know this beforehand your IQ is more than likely less than 75.

I have a good idea for you. Just get all your news and feature stories from Fox and conservative radio, and you'll be fine. You're all the same. No matter what story is written on MSN or posted on Yahoo or other mainstream media, the only thing your kind has to offer is negative, sarcastic comments. It's so obvious when you do it on a site like MSN. BTW: Before you make the tpyical lib comment, I'm an independent. Which means I don't blindly follow any party line.
