Myth

Sleep is a Waste of Time

•  Historically, we knew its importance…not why

Why We Sleep? •  For Restoration

–  Genes turned on during sleep –  Slow wave sleep

•  Energy Conservation –  Only 110 calories saved from not sleeping

•  Brain Processing and Memory Consolidation –  Enhances creativity by 3 fold – synaptic connections strengthened…. –  Brain development - critical

•  Overall – mental function, immune function, growth and tissue repair

Myth Sleep loss does not affect me I can make up for sleep deprivation

….6450, 6451, 6452….

I think I can….. I think I can….. I think I can…..

Sleep Deprivation/Loss

•  Weight gain (50% chance of obesity at 5 hrs of sleep) – –  Less loss of fat when dieting if you don’t sleep well (Van Cauter,

Sleep, 2012) –  Risk of obesity with sleep loss in children (Chaput, J Public Health,

2011) –  Increased risk of obesity with sleep fragmentation (Narang, CMAJ,

2013)

•  Injury –  86% increase in risk for injury in 3-5 yr old with < 10 hrs of sleep per

night the night before the accident (boto LR, Sleep Medicine, 2012)

•  Risk taking behavior –  Teens - More likely to gamble (Beebe, 2012)

Sleep Deprivation •  Average sleep time 2013: 6.5 hrs •  Current sleep time 2013: 5 hrs

•  The “at risk”: shift work, teens, jet lag, etc.

•  Microsleeps: your brain coping: 31% drivers will fall asleep at the wheel at least once in their life… can be deadly!!!

Sleep

INCREASES/IMPROVES: •  Attention •  Concentration •  Creativity •  Ability to socialize •  Decision making •  Mental health •  Physical health

DECREASES: •  Mood changes •  Stress •  Impulsiveness •  Fatigue •  Anger •  Inattention •  Risk taking behaviour (drink

and take drugs)

disrupt sleep •  Medications in adults do exist but even for

them recommended for short term and in conjunction with behavioral strategies

•  More is not always better – melatonin…
