Sleep Cycle
This stage of sleep comes with an increased rate of respiration brain activity and is when dreaming occurs
What is REM sleep?
Throughout a full nights sleep, the amount of REM sleep per cycle does this
What is increase
These body parts are observed moving rapidly in deep sleep
What are the eyes?
This sleep disorder describes regular issues with falling and staying asleep
What is insomnia?
Sleep is theorized to help consolidate and store these after their collection throughout the day
What are memories?
This stage is the transition from wakefulness to sleep
What is NREM-1 sleep?
This type of brainwave appears at the start and end of a sleep cycle
What are Beta waves?
The sleep-inducing hormone whose production is linked to the circadian rhythm
What is melatonin?
This disorder, more common in children, involves harsh movements and speaking nonsense
What is night terrors?
The restorative function of sleep is called into question by this degree of brain activity observed during sleep
What is high?
This stage is when sleep spindles occur
What is NREM-2 sleep?
The period(s) of a cycle when brain activity is the highest
What is the beginning?
Energy levels if woken consistently do this throughout the night
What is increase?
This disorder provokes normal waking activities (sitting up, walking) while asleep and occurs during NREM-3 sleep.
What is sleepwalking?
Sleep supports growth when this gland releases growth hormone
What is the pituitary gland?
The sleeper is quite easily awakened during this stage. Respiration starts to decrease and heart rate begins to slow.
What is NREM-2 sleep?
False memories stemming from impaired function in the hippocampus, prefrontal cortex, and parietal lobe can be observed as a byproduct of this
What is sleep deprivation?
The body’s ability to synchronize its sleep cycle with a 24-hour day
What is the circadian rhythm?
This disorder, most commonly associated with obesity, frequently halts breathing while asleep
Sleep can inspire creative thinking by introducing these at night
What are dreams?
This stage is sometimes referred to as delta sleep. Bed-wetting and sleepwalking are most likely here.
What is NREM-3 sleep?
Alpha, Beta, Delta, and Theta brainwaves first appear in this sequence in a sleep cycle
What is Beta, Alpha, Theta, Delta?
Throughout a full night’s sleep, body temperature generally ranges from a maximum point of 100º to a minimum of this
What is 96º?
This rare disorder causes sudden attacks of overwhelming sleepiness
This sleep theory helps explain why athletes perform better after a full night’s sleep
What is growth?
