7. THE PURPOSE OF SLEEP RESTORATION & SURVIVAL
There are many different theories about why we sleep.
These theories include:
RESTORATION
&
SURVIVAL
KK 2 – PAGE 160

8. THE PURPOSE OF SLEEP RESTORATION
RESTORATIVE THEORIES OF SLEEP
(Recovery theories/Restore & Recovery Theories)
These theories propose that sleep provides ‘time out’ to help us recover from depleting activities during waking time that use up the body’s physical and mental resources
NREM REM

9. THE PURPOSE OF SLEEP RESTORATION –NREM SLEEP
RESTORATIVE THEORIES OF SLEEP
NREM SLEEP – Important for restoring and repairing the body
REM SLEEP – Restore the brain as well as play a role in memory and learning
Provides regular ‘exercise’ to groups of neurons in the brain
Assists in consolidating or embedding the memory of newly learned information

10. THE PURPOSE OF SLEEP RESTORATION –NREM SLEEP
REM REBOUND
People in sleep laboratories were regularly woken when they began REM sleep
Researchers found that when they were
allowed to sleep again, they spent
longer in REM sleep than they normally would

11. THE PURPOSE OF SLEEP SURVIVAL
SURVIVAL THEORIES OF SLEEP
(Adaptive Theories/Evolutionary Theories/Preservation & Protection Theories)
These theories propose that sleep evolved to enhance survival by protecting an organism through making it inactive during the part of the day when it is most risky and dangerous to move about (Meddis, 1977)
EVIDENCE:
Animals with few natural predators sleep for longer periods of time
Animals with many natural predators sleep for shorter periods of time
We sleep at night because we need light to see
BUT WHY DOES SLEEP INVOLVE A LOSS OF CONSCIOUSNESS?
