Read the following passage adapted from a research article about the effects of sleep on cognitive function:
Recent studies indicate that sleep plays a crucial role in various cognitive processes. For instance, research has shown that deep sleep promotes memory consolidation, a process where short-term memories are transformed into long-term ones. Furthermore, insufficient sleep can lead to impairments in attention, problem-solving abilities, and overall cognitive flexibility.
Given these findings, understanding sleep's impact on our mental acuity is essential, especially in our fast-paced society where sleep is often undervalued. Experts recommend striving for 7-9 hours of quality sleep per night to optimize cognitive functionality.
