9. How much sleep do you need or want?
• Studies that paid people to sleep
Participants asked to be “well rested”
• Definition of “well rested”
Not being able to fall asleep
in a darkened room mid-day

Most adults need 7 - 9 hours of sleep
10. GOAL: 7-9 hours of sleep
Debate:
•All At Once vs. Naps
•All At Night = Gold Standard
Naps =
• Good Option in order to reach 7-9 hours
• Consider Power Nap (10 - 30 minutes)
• Longer Naps may disrupt night time sleep

19. Sleep Duration & Adipokines
Each hour of reduced sleep time
•
6 % increase in leptin (p = 0.01)
•
↑ Leptin
• Potential furthering of
leptin resistance
14 % increase in visfatin (p = 0.02)
Each hour of reduced REM
•
15 % increase in leptin (p = 0.01)
•
31 % increase in visfatin (p = 0.05)
↑ Visfastin
• Competitive inhibition of
insulin receptor binding
Other studies note
increased IL-6, TNF α, &
adiponectin

in 4 years

– (OR 2.9: [1.5- 5.6])

sleep is of top priority– it will provide better ‘Me Time”
If sleeping were a pill,
its label would list:

(1)Intimacy
(2)Sleep
NOT for work, worry, or
problem solving
