Which statement about sleep is accurate?

Lack of sleep impairs judgment, focus, and overall mood is accurate because numerous studies have demonstrated that insufficient sleep negatively affects cognitive functioning. When an individual does not get enough sleep, it can lead to decreased alertness, poor decision-making, and difficulty concentrating on tasks or absorbing information. This impairment can extend to emotional regulation as well, often resulting in irritability and heightened stress.

Additionally, sleep plays a vital role in consolidating memories and processing information. A well-rested mind is more capable of critical thinking, creativity, and performing well academically. In contrast, statements suggesting that lack of sleep enhances creativity or improves test performance are misleading, as research consistently shows that rest deprivation hampers cognitive performance rather than improving it.
