The theory states sleep is to allow the body to rest, restore and repair. However, theories debate whether it's the body or brain that needs rest.

OSWALD
- believes SWS is useful for the body's recovery process
- During SWS there is a release of the growth hormone from the pituitary gland
*providing suppport for the theory as this may stimulate protein synthesis and contribute to repair of body tissue
-Also argued important recovery process for the brain during REM sleep.
Overall, NREM sleep good for body, REM good for brain

HORNE
-Similar to Oswald's theory
-Argued humans have periods of using little energy during relaxed wakefulness. Repair of body tissue can occur during this rather than sleep
-However, central to both is that sleep is essential for survival. Disagreements concern precise mechanisms involved in recovery/restoration
-Sleep is important for recovery of cerebral function - especially prefrontal cortex - important role in decision making/unexpected events which sleep deprivation has negative effects on
-This theory is more applicable to advanced mammals

Sterne and Morgane...
REM sleep specifically for restoring brain neurotransmitters. After REM deprivation,ppts show 'rem rebound'

Restoration of the body (physiological restoration)
If this is the function, we expect to see:
