Sleep is critical for students' memory consolidation, learning and cognitive function. Students who do not get enough sleep are more likely to struggle with concentration, problem-solving and retaining information. This can negatively impact their academic performance, leading to lower grades and decreased productivity in school. Studies have shown that students who sleep more get better grades. However, many students give up sleep to get good grades. This article will explore the topic of why students need more sleep.

What You'll Learn

Sleep and academic performance
Sleep plays a larger role in academic performance than most may realise. Executive functions (the mental skills involved in planning, paying attention, and multitasking, for example) underlie the impact of sleep on academic performance, and these skills are more critical in maths and languages than other subjects. Short or poor sleep is a significant risk factor for poor academic performance that is frequently ignored.
Measures that were indicative of sleep quality were mostly linked with students’ performances on verbal reasoning tests and on grade point averages on tests at school. So it appears from their results that “longer sleep” is more closely related to academic performance, while “good night sleep” is more closely related to overall cognitive processing.
The National Sleep Foundation recommends that children aged five to 12 get 10-11 hours of sleep a night. Teenagers need about eight to 10 hours, but studies suggest only 15% of them get it. The CDC recommends that students follow a consistent sleep schedule, even on weekends, to regulate their internal clocks.

Sleep and mental health
Sleep also influences our emotions, ability to manage stress and overall wellness. Sleep disorders can cause or contribute to significant behaviour and mental health issues, including attention-deficit/hyperactivity, anxiety, depression and difficulties associated with emotional dysregulation.

Sleep and physical health
Sleep is essential for students' physical health. According to the Centers for Disease Control and Prevention and the National Institutes of Health, adequate sleep is fundamental for physical health, mental clarity, and overall quality of life, particularly for young people. Sleep allows both the body and brain to recover during the night, ensuring students feel refreshed and alert when they wake up in the morning.
Students who do not get enough sleep are more likely to struggle with concentration, problem-solving and retaining information. This can negatively impact their academic performance, leading to lower grades and decreased productivity in school. Lack of sleep is also linked to a higher risk of obesity, diabetes and other chronic health conditions. For students, this can mean decreased energy levels and increased susceptibility to illness, preventing them from fully participating in school activities.
Research shows that students who sleep more get better grades. However, many students give up sleep to get good grades, and college students are one of the most sleep-deprived populations. The National Sleep Foundation recommends that children aged five to 12 get 10-11 hours of sleep a night, while teens need about 8-10 hours.
To combat these issues, the CDC recommends that students follow a consistent sleep schedule, even on weekends, to regulate their internal clocks. This can be achieved through improved sleep hygiene, or habits that support good sleep. By prioritising sleep, students can improve their academic performance, enhance their physical and mental health, and set themselves up for long-term success.

Sleep and memory consolidation
Sleep is critical for memory consolidation, learning and cognitive function. Students who do not get enough sleep are more likely to struggle with concentration, problem-solving and retaining information. This can negatively impact their academic performance, leading to lower grades and decreased productivity in school.
Research shows that students who sleep more get better grades. In a recent study involving 48 students between 16 and 19 years old, researchers at the Lifespan Learning and Sleep Laboratory at UCL examined the link between sleep, academic performance, and environmental factors. The study found that "executive functions (the mental skills involved in planning, paying attention, and multitasking, for example) underlie the impact of sleep on academic performance, and these skills are more critical in math and languages than other subjects. Short or poor sleep is a significant risk factor for poor academic performance that is frequently ignored".
