Sleep as Restoration
Captions available
The idea
The restorative theory holds that sleep exists to repair and replenish the body and brain after waking activity.
In practice
Growth hormone release and tissue repair are concentrated in deep sleep rather than in waking rest.
Where people slip
Restoration explains why sleep helps and not why it takes this form. A second account is needed.
