**Core Concept**
Slow wave sleep (SWS) is a stage of non-rapid eye movement (NREM) sleep characterized by low-frequency brain waves, specifically delta waves (0.5-4 Hz). It is crucial for physical recovery, memory consolidation, and the release of hormones that regulate growth and development.

**Why the Correct Answer is Right**
Slow wave sleep is associated with the release of growth hormone, which stimulates growth and cell reproduction. Additionally, SWS is linked to the clearance of beta-amyloid plaques, a hallmark of Alzheimer's disease. The parasympathetic nervous system is also active during SWS, promoting relaxation and reducing stress.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the release of growth hormone is indeed associated with slow wave sleep.
**Option B:** This option is incorrect because the clearance of beta-amyloid plaques is also linked to slow wave sleep.
**Option C:** This option is incorrect because the parasympathetic nervous system's activity is indeed a characteristic of slow wave sleep.

**Clinical Pearl / High-Yield Fact**
It's essential to note that slow wave sleep is not just a passive state but an active process that involves the coordinated effort of various physiological systems. Disruptions to SWS have been linked to various health issues, including cognitive impairment and metabolic disorders.

**Correct Answer:** C.
