What is a limitation of the Restoration Theory?

The limitation of the Restoration Theory highlighted by the selection indicates that cell repair processes and overall body recovery can occur continuously, not exclusively during sleep. This implies that while sleep undoubtedly plays a critical role in restorative functions, it is not the sole period during which bodily repair and rejuvenation occur. The fact that these processes can happen throughout the day challenges the idea that sleep is the exclusive time for recovery, suggesting that the importance of sleep in repair might be overstated within the confines of this theory.

The other options reflect different aspects of sleep and its nature, such as the specific type of REM sleep associated with dreaming, the idea that all sleep has the same restorative effect, or the notion of sleep's impact on emotional behavior. However, they do not directly address the primary limitation regarding the role and timing of restoration processes within the framework of the Restoration Theory, as effectively pointed out by the selected statement.
