Hi all. I know this is an old thread but I was going to post what is below in a thread
on exercise, but when I did a search I found this to be much more relevant.
I haven't read the posts here, at least not yet. My plan is to increase my aerobic
exercise starting this week in the hopes it will help my sleep and one or two other things.
Article comments on exercise and sleep. Only some excerpts below:
Add one more benefit: sound sleep. Did you know that exercise can help you sleep sounder and longer and feel more awake during the day? It's true. But the key is found in the type of exercise you choose and the time you participate in it during the day.
Exercising vigorously right before bed or within about three hours of your bedtime can actually make it harder to fall asleep. This surprises many people; it's often thought that a good workout before bed helps you feel more tired. In actuality, vigorous exercise right before bed stimulates your heart, brain and muscles -- the opposite of what you want at bedtime. It also raises your body temperature right before bed, which, you'll soon discover, is not what you want.
When it comes to having a direct effect on getting a good night's sleep, it's vigorous exercise in the late afternoon or early evening that appears most beneficial. That's because it raises your body temperature above normal a few hours before bed, allowing it to start falling just as you're getting ready for bed. This decrease in body temperature appears to be a trigger that helps ease you into sleep.
The type of vigorous workout we're talking about is a cardiovascular workout. That means you engage in some activity in which you keep your heart rate up and your muscles pumping continuously for at least 20 minutes. Although strength-training, stretching, yoga, and other methods of exercise are beneficial, none match the sleep-enhancing benefits of cardiovascular exercise.

While the brain is still able to process information, the information may be distorted before it’s processed, Huettel said. One night without sleep can lead to increased activity in the regions of the brain that weigh positive outcomes, and decreased activity in areas that assess negative outcomes, according to an fMRI study of 29 people by Huettel and his colleagues published in the Journal of Neuroscience last year.
“If you make someone more attentive to good outcomes and less attentive to bad outcomes, it will look like they’re more risk-seeking than they are,” Huettel said in a telephone interview.
The trial, funded in part by Singapore’s Defense Science and Technology Agency, was the first to show that sleep loss could change the way the brain determines economic value, making people more likely to make choices that increased monetary gain and less likely to select options that reduced loss, the Duke researchers said.
