University of Michigan study:

"Making $60,000 more in annual income has less of an effect on your daily

happiness than getting one extra hour of sleep a night," says study author Norbert Schwarz, Ph.D., a professor of psychology.

Columbia University 2004 study:

Specifically, the study found that subjects who slept four hours or less per night

were 73 percent more likely to be obese than those who slept between seven and

nine hours each night.

National Sleep Foundation:

Sleep research has shown that sleeping too little can not only inhibit your productivity and ability to remember and consolidate

information, but lack of sleep can also lead to serious health consequences and

jeopardize your safety and the safety of individuals around you.

School of Medical Sciences, Capinas, Brazil (2007) :

“Nocturnal computer use impairs good sleep…irregular sleep patterns associated with nightly computer use deteriorate good sleep quality.”

What works?

• Attaching to existing habits• Providing “hot triggers”• Aiming to change small behaviors

Promote Napping

• Berkeley study (2010): Hippocampus function improved with a 90-minute nap1

Promote Napping• Dr. Sara Mednick, author of “Take a nap, change your life”

THE NANO-NAP: 10 to 20 seconds. Benefits unclear.THE MICRO-NAP: two to five minutes. Shown to be surprisingly effective at shedding sleepiness. THE MINI-NAP: five to 20 minutes. Increases alertness, stamina, motor learning, and motor performance. THE ORIGINAL POWER NAP: 20 minutes. Includes the benefits of the micro and the mini, but additionally improves muscle memory and clears the brain of useless built-up information, which helps with long-term memory (remembering facts, events, and names). THE LAZY MAN’S NAP: 50 to 90 minutes. Includes slow-wave plus REM sleep; good for improving perceptual processing; also when the system is flooded with human growth hormone, great for repairing bones and muscles.

Natural Light

• Those exposed to more natural sunlight have more consistent Circadian rhythms

• Stanford Medical School: “After 16 weeks in a moderate intensity exercise program, subjects were able to fall asleep 15 minutes earlier and sleep about 45 minutes longer at night.”
