Tony Wright, horticulturalist, broke the unofficial world record by going without sleep for more than 11 days. His trick was, when the left side of his brain tired, to switch to the right side. And then back again after the left had recovered and so on.
For her final project in a Media Lab class, Anita Lillie fastened three accelerometers to her body and tracked her movements while asleep. The data recorded allowed her to determine her sleeping positions and orientations (on her left side, on her back, etc.) and how they changed through the night.
Jamie reviews some online wake-up services. "when you select the secureawake feature, snoozester will attempt to call you every 3 minutes for 20 minutes until you answer the call and indicate that you are awake."
Photos of people sleeping. Each series of photos depcits a full night's sleep. (via cyn-c)
"A six-year Greek study found that those who took a 30-minute siesta at least three times a week had a 37% lower risk of heart-related death." Among working men, the risk was reduced by 64%. Naps all around!
Five reasons why Americans might be getting fatter that you haven't thought of. "Sleep-deprived animals eat excessively, and humans subject to sleep deprivation show increased appetite and an increased Body Mass Index, the standard measure of excessive weight."

How to become an early riser. "The solution was to go to bed when I'm sleepy (and only when I'm sleepy) and get up with an alarm clock at a fixed time (7 days per week)."
