• Infant – first year – at least ½ of her/his life sleeping
• It is as important as AIR and WATER for SURVIVAL!
• 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

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)

Myth Sleep, Oh Beautiful and Perfect Sleep
Reality: Shame and Blame • Bedtime troubles is __________’s fault! • S/he will outgrow it • I am the only one affected by it…. • I need to take care of the other stuff • I must be doing something wrong • There must be a magic pill • Nobody listens or can help
The facts: • Bedtime troubles are common in children
– Increased likelihood if developmental disabilities – Can become lifelong
• Over the counter preparations, although have sleepiness as a side effect may not address the underlying reason for the sleep problem
• It is best to work with a health professional knowledgeable about sleep to address the concerns
The facts: • Alcohol and caffeine are not sleep aids. They
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…
