SleepHow sleep worksCircadian rhythm and light

William C. Dement explains the fundamentals of healthy sleep, the dangers of sleep debt, and how sleep impacts daily performance.

Google Tech Talks September 23, 2008 ABSTRACT Under ordinary circumstances, healthy sleep is by far the most powerful determination of high-level performance and productivity. Three major characteristics must be present to define healthy sleep. They are (1) a sufficient amount and continuity to avoid sleep indebtedness, (2) absence or near absence of pathological sleep-related events and (3) reasonable synchronizing of desired time in bed with circadian predisposition. The nature of each of these three characteristics will be elaborated as well as their relation to performance. Speaker: Dr. William Dement William C. Dement, M.D., Ph.D., is the world's leading authority on sleep, sleep disorders, and the dangers of sleep deprivation. He is Chief of the newly created Division of Sleep at Stanford University School of Medicine, which is also the home of the world's first sleep disorders center founded by Dr. Dement. Born and raised in the state of Washington, Dr. Dement remained in his home state for his undergraduate years at the University of Washington. He then pursued his graduate studies at the University of Chicago, receiving his M.D. in 1955 and Ph.D. in Neurophysiology in 1957. For more than half a century, Dr. Dement has conducted basic sleep research, investigated sleep disorders and treatments, and has launched a myriad of public education programs. From 1953 to 1957, he conducted the first studies leading to the characterization of rapid eye movement (REM) sleep, the basic REM/NREM sleep cycle, and all night sleep patterns. In 1975, Dr. Dement founded the American Academy of Sleep Medicine serving as its President for twelve years. Dr. Dement was also a founder of the American Board of Sleep Medicine. From 1990-1993, he served as Chairman of the U.S. Congress's National Commission on Sleep Disorders Research. In 2001, he received the largest National Institute of Health research grant in sleep medicine history to establish the effectiveness and benefits of continuous positive air pressure (CPAP) treatment for large populations of patients with obstructive sleep apnea. As the author or co-author of over 500 scientific publications, Dr. Dement's research, findings, and advice can be found amongst several texts including his own, The Sleepwatchers, and most recently, The Promise of Sleep. He is also co-editor of the definitive textbook, Principles and Practice of Sleep Medicine, now in it's 4th edition. Dr. Dement's strong desire to educate students about sleep and the dangers of sleep deprivation led to the creation of his very popular course, "Sleep & Dreams," at Stanford University, which he has been presenting regularly for over 35 years. He will continue his efforts to educate the public and increase sleep awareness as long as he lives.

On “Prolonged Partial Sleep Deprivation for a Job (The worst year of my life [so far])”

I don't have any sleep disorder and never really paid much attention to the duration of my sleep or the time to go to bed. After watching this video link to this video ( Dr. William Dement on Healthy Sleep and Optimal Perfomance ) I'm going to bed at 11 and waking at 7 with excelent results.

Getting enough sleep? Definitely worth a watch: link to this video Personally, I found that taking a full-time programming job destroyed my out-of-office motivation and productivity. It might be worth trying a job in a new industry for a while, or working out some sort of part-time agreement with your employer -- you might find your brain itching to code and produce something after work hours.

On “Finding the Joy in Feeling Tired”

Lauded Stanford sleep researcher William Dement has done a lot of work to characterize fatigue and drowsiness. Generally speaking his conclusion is that sleep debt is extremely common and also damaging. He gave an hour talk at Google going over many of his results. His manner in this is informal and drags a bit but the information is potentially extremely valuable for anyone experiencing the feeling of tiredness: link to this video Personal Growth Series: Dr. William Dement on Healthy Sleep and Optimal Performance

On “Thomas Edison and the Cult of Sleep Deprivation”

Related google tech talk: link to this video Somewhere in the middle he describes experiments they made with sleep. Essentially, they took a person, made them sleep a lot and then measured performance difference. Performance went up. Sleep a lot meant sleep enough to recover from sleep dept and then around 8 hours every night.

On “How to Sleep”

William Dement gave a Google Tech talk on September 23, 2008. Dement recalls that Randy Gardner who stayed awake for 11 days in 1964, when asked some 40years later " would you do this again? " he replied " No way would I do this again " 0 Very interesting from Dement's talk is that equilibrium daily average sleep for completely health young adults is 8:15 ± 50min 1. Most people I meet contest these results and state that they can work optimal with less than 7h25m daily sleep. 0 link to this video 1 link to this video

On “Benefits of Napping in Healthy Adults (2009) [pdf]”

Managed to find this talk I watched many years ago on Google Video: link to this video IIRC, the professor explained that if you fall asleep faster than around 10-15 minutes, you're probably sleep deprived and need to sleep more.
