The Bigger Picture

2

➢ Sleep is a biological requirement for

human life

• Needs met based on both quantity and quality

➢ Yet our society perpetuates the idea that

sleep is unproductive time

➢ The truth is that since at least the 1960s,

we have known that sleep is an important predictor of morbidity and mortality

Guidelines for Adequate Sleep

American Academy of Sleep Medicine and Sleep Research Society: 7 or more hours National Sleep Foundation: 7-9 hours American Thoracic Society: 7-9 hours American Heart Association: 7 or more hours

Habitual short sleep duration is highly prevalent in the US population

• People who habitually sleep 6 hours or less
• Are more likely to be overweight or obese
• Gain more weight, faster
• Have more trouble losing weight
• This (and other impacts of sleep loss) leads to
• 55% increased likelihood of becoming obese
• 21% increased likelihood of developing high blood pressure
• 33% increased likelihood of developing diabetes
• Insufficient sleep is also associated with
• Impaired organ function across systems
• Impaired immune system
• Greater pain and pain sensitivity

Sleep, Weight & Heart

Sleep regulates brain function

• Sleep plays key roles for emotion regulation
• Insomnia and sleep loss are key risk factors for

depression and anxiety disorders, and predict recurrence of episodes

• Insomnia and nighttime wakefulness are major

risk factors for suicide

• Sleep plays critical roles in clearing waste and toxins from

the brain, implications for Alzheimer’s and other dementias

• Sleep loss impacts decision-making
• Risk-taking behavior
• Judgment and planning
• Processing multiple sources of information
• Not fixed by stimulants
• We are often unaware of the consequences

Recognition of Sleep

Maia, Grandner, Findley, and Gurubhagavatula et al., 2013

BRFSS 2009

• Sleep is increasingly recognized as the “third pillar
• f health”
• There has been an explosion of public interest in the

health and performance benefits of healthy sleep

• Sleep is easier to change than diet or exercise so

people notice benefits

• And has strong placebo effects
• Healthy sleep can fit with the narrative of both

health and productivity

• Most PCPs recognize the importance of healthy

sleep but don’t know what to recommend to patients

Sleep and Metabolism

9

• Calories close to sleep will be more likely to be

converted to weight gain

• Changes in sleep affect how your body processes food,

including causing changes in:

• What you choose to eat
• When you choose to eat
• Your blood sugar
• Gaining or losing weight

KEY OPPORTUNITY AREAS

10

• Rethinking the standard approaches
• Harness the rebuilding process
• Addressing potential deficiencies that can cause sleep problems
• Role of an optimal diet (and supplements) in sleep health
• Embracing chronotherapeutics
• Approaching the morning
• And others!
