Sleep for Success!
Everything you mustknow about sleep
but are too tired to ask...
The Sleep Deprivation Crisis
• Most people are moderately to severely sleep deprived. 71% do not meet the recommended 7.5-9.5 hrs/nt. (7? or less?)
• High school & college students arewalking zombies
Even middle schoolers are exhaustedand inattentive...
75%of adults experience sleep problems each week.
• Difficulty falling asleep• Middle of the night awakenings • Wake up too early
All this causes daytime sleep inertia (grogginess and lack of mental clarity)
1. Does a heavy meal, low dose of alcohol,
warm room, boring meeting or lecture ever
make you drowsy?
2. Do you fall asleep instantly at night?
3. Do you need an alarm clock to wake up?
4. Do you repeatedly hit the snooze button?
5. Do you sleep extra hours on weekends?
Are You Sleep Deprived?
The main obstacles for not getting enough sleep:
• Can’t shut brain off• Young children• Stress• Going to bathroom• Dog or cat• Partner with sleep apnea
Text
Blocks to getting the sleep necessary to be successful
- We don’t understand the importance of sleep- We don’t know how to obtain great sleep- We might suffer from sleep disorders- We overuse electronic devices that block melatonin- We think we can accomplish more if we sleep less- Our culture devalues sleep!

Quality and quantity of sleep determines waking success!
‣ Mood‣ Alertness‣ Energy‣ Thinking‣ Academic Performance‣ Social relationships‣ Athletic ability‣ Health‣ Longevity
“There are not enough hours in the day!”
If you get adequate sleep:better mood,efficient,effective = some free time
“Top executives have a critical responsibility to take sleep seriously. Educational programs about sleep should be mandatory. If you want to raise performance you need to pay attention to this fundamental biological process.
Encouraging a culture of sleepless machismo is worse than nonsensical; it is downright dangerous and the antithesis of intelligent management.”

• The sleeping brain is highly active:1) Regulates immune, hormone & endocrine functions essential for general health
Recent Research on Sleep
Sleep deprivation leads to: Significantly higher risk of Hypertension (heart attacks & strokes), Type II diabetes, Depression, Influenza, Skin and Allergy Problems, Cancer, Alzheimer’s Disease, Obesity.
Pilcher J, Huffcutt A. Effects of sleep deprivation on performance: A meta-analysis. Journal of Sleep Research & Sleep Medicine. 1996;19(4):318-326.
People who sleep 6 hours or lesseach night lower their resistance to
viral infection by 50%.

2) Puts new information into neural networks for long term storage... essential for memory, learning, performance, problem-solving, creativity and athletic excellence.

All mental events enter hippocampus.
SLEEP for peak performance
Sleep transfers information to the cerebral cortex and forms new connections of facts & concepts(memory traces).
Hippocampus
Temporal lobePrefrontalcortex
Need 8 hrs. sleep for maximum transfer and retention.
The brain can beirreversibly injured from sleep loss.

Individual differences, genetically determined
Golden Rules for Peak Performance
From puberty to 24 you need 9.25 hours sleep
20% fall asleep in schoolInternal clock bedtime 3am, wake time 11am
Czeisler, C and Wright, K. Influence of Light on Circadian Rhythmicity in Humans. Regulation of Sleep and Circadian Rhythms. 1999;149–180.
Consequences of Shortened Sleep• Increased heart disease, diabetes, cancer, obesity• Drowsiness/microsleeps/unintended sleep seizures• Increased irritability, anxiety, depression (disconnect
between prefrontal cortex and amygdala)• Decreased socialization skills & sense of humor• Decreased motor skills and reaction time (driving) • Decreased cognitive performance:Reduced ability to process, concentrate & rememberReduced ability to communicateReduced ability for complex/multi tasking & creativityPoor decision skills and increased risk-taking • In sum: Reduced health and performance
Chronically limited sleep produces progressive neurological dysfunction in
attention and memory.Two weeks at 6hrs/nt.= One all-nighter.

Post-flight:
If you flew east...and it’s morning at your destination but still the middle of the night in your head, don’t go to sleep
If you flew west...and it’s already evening according to your biological clock, spend time outdoors in the sun
