Read the passage below:
In a recent study exploring the effects of sleep on academic performance, researchers found that students who consistently received less than six hours of sleep per night scored significantly lower on standardized tests than their well-rested peers. The study also indicated that sleep deprivation affected not only cognitive functions like memory and attention but also emotional stability, leading to higher levels of stress and anxiety among sleep-deprived students. Researchers recommend that educational institutions prioritize awareness about the importance of sleep among students and suggest that schools start later in the morning to help improve overall academic performance.
