3.4 Sleep-Rest Pattern Flashcards
At what age does a child typically sleep through the night **consistently **
3 years old
How is sleep related to obesity
poor sleep is a risk factor for obesity
What is too little sleep associated with for adolescents? (1)
What about for school aged kids? (2)
adolescents- high risk behaviours
school aged- poor academic performance, depression
What is insomnia
sleep onset delay of more than 30 minutes per night and/or frequent prolonged night waking
+
with impaired daytime functioning
How does the blue light from electronic devices impact sleep
supresses melatonin
supression lasts through the nigth
Starting at 3 months what is the best advice for infant sleep routine
put baby to bed when drowsy but not asleep to allow them to initate sleep independently
Behavioral interventions before 3 months of age are not recommended because infants still need to feed frequently.
Why should nursing or bottle feeding an infant to sleep/back to sleep be avoided after newborn period (0-3 months)
infant will associate being fed with returning to sleep
At what age do circadian rhythms emerge in people
2-3 months old
What affects circardian rhythm
melatonin from hypothalamus
A special center in the hypothalamus, called the
suprachiasmatic nucleus (SCN), releases melatonin in response to darkness, as perceived by a nerve pathway from the retina in the eye.
What are the two phases of the normal sleep cycle
Rapid eye movement- REM
Nonrapid eye movement - NREM
REM is where dreams happen- REM is highest in infants and decreases with age
When do infants vs older children experience REM sleep
infants go right into REM, older children/adults go into NREM first
REM sleep can be active in newborns with audible suckling.

What type of deaths do Sudden unexpected infant death (SUID) and sudden unexpected
death in infancy (SUDI) describe?
any sudden and unexpected death—explained or unexplained including sud-
den infant death syndrome (SIDS).
SUDI describes infant death from suffocation, asphyxia, entrapment, infection, ingestions,
metabolic diseases, and trauma (unintentional or nonaccidental)
SIDS is a subcategory of Sudden unexpected infant death (SUID) - what are SIDS deaths
SIDS- defined as infant deaths that are
unexplained after a thorough case investigation including autopsy,
a scene investigation, and clinical history.
What is the working model of why SIDS is thought to happen?
interaction between a vulnerable infant and potentally asphyxiating and or overheating sleeping environment
