What You'll Learn
Sleep deprivation and its causes
Sleep deprivation is a common issue among university students, with a large-scale study finding that 36% of US university students sleep less than 7 hours each night. The average amount of sleep university students get is between 6 and 6.9 hours every night, while the recommended amount is around 8 hours.
The main causes of sleep deprivation among university students include poor sleep hygiene, biology, use of technology, and use of drugs. Poor sleep hygiene refers to behaviours that negatively impact sleep, such as irregular sleep schedules, late-night socialising, early morning obligations, and the use of caffeine, alcohol, and other stimulants. The effects of caffeine can last for more than seven hours, and college students are more likely to use prescription and non-prescription stimulants, which can disrupt sleep. Additionally, electronic devices emit light, which reduces the body's production of melatonin, a natural sleep aid.
Biological factors, such as leaving home, increased independence, changes in peer groups, new social situations, and increased access to alcohol or drugs, can also contribute to sleep deprivation. About 90% of university students have roommates, and 41% wake up at night due to noise. Bedtimes and wake-up times during the week and weekends can differ by more than 1-2 hours, leading to irregular sleep patterns.
The consequences of sleep deprivation among university students are significant. It can negatively impact their GPA, with every lost hour of nightly sleep associated with a 0.07-point drop in GPA. Sleep deprivation can also lead to physical and emotional problems, including weight gain, obesity, decreased energy levels, impaired memory and attention span, and increased risk of accidents, especially for those who commute by car. Additionally, it can affect mood, relationships, and mental health, with students experiencing increased irritability, impaired decision-making, reduced feelings of gratitude, and higher risk of depression and anxiety.

Sleep disorders
Poor sleep and sleep deprivation can have serious implications for students' physical and mental health, as well as their academic performance. Students with sleep disorders are more likely to perform poorly in their studies, with a lower GPA. This is due to the impact of sleep deprivation on the brain's ability to process and retain information, as well as on attention span and memory. The effects of poor sleep on academic performance are similar to those of binge drinking or being in an abusive relationship.
There are several factors that contribute to sleep disorders in university students. One major factor is the use of stimulants such as caffeine and energy drinks, which can increase the time it takes to fall asleep, suppress REM sleep states, and negatively impact sleep quality. The effects of caffeine can last for more than seven hours, making it harder to fall asleep and stay asleep. The use of alcohol as a sleep aid is also common, with almost 12% of students reporting that they use alcohol to help them sleep. While this may help them fall asleep, it can cause sleep fragmentation and increase the risk of developing obstructive sleep apnea.
Another factor contributing to sleep disorders is the use of electronic devices, which emit light that can reduce the body's production of melatonin, a natural sleep aid. Additionally, the stress of academic performance, financial worries, and social distractions can also impact sleep quality.
The good news is that there are interventions that can help university students improve their sleep. For example, the SWIS sleep training program has been shown to improve sleep quality and sleep-related personality traits in students with insomnia. Additionally, campus programs that address sleep habits and promote better sleep patterns can be beneficial, especially for freshmen who are adjusting to the demands of college life.

Sleep and academic performance
Sleep is essential for optimal academic performance, and university students often struggle to get sufficient, quality sleep. Multiple factors contribute to sleep deprivation among university students, including variable class schedules, late-night socialising, early morning commitments, stress, and the use of stimulants and technology. This can have significant consequences for their health, well-being, and academic success.
University life presents unique challenges that can disrupt sleep patterns and quality. The transition to university often involves leaving home, increased independence, new social situations, and academic pressures. These adjustments can be demanding and impact sleep habits. Additionally, the freedom and accessibility of substances like alcohol and drugs can further contribute to sleep disturbances.
The impact of sleep deprivation on academic performance is well-established. Studies have found that university students who get less sleep tend to have lower GPAs. Every hour of lost sleep at the start of an academic term was associated with a 0.07-point drop in a student's end-of-term GPA. This effect is even more pronounced when students sleep less than six hours a night. Sleep-deprived students may experience decreased attention span, impaired memory, and reduced ability to focus and learn in class.
Furthermore, sleep plays a crucial role in consolidating information and improving learning outcomes. When students sacrifice sleep to study, their ability to retain and recall information diminishes. Adequate sleep also contributes to improved mood, decision-making, and overall well-being, which can positively impact academic performance.
To mitigate sleep deprivation and improve academic outcomes, universities can implement campus programs and interventions focused on sleep education and building better sleep habits, especially during the critical first year of university. By addressing sleep hygiene, sleep environments, and stimulants, students can enhance their sleep quality and, subsequently, their academic performance.

Sleep and mental health
Sleep is essential for the well-being of university students, yet many struggle with sleep problems and sleep deprivation. This issue has significant implications for their mental health, which is already vulnerable due to the stresses of academic life.
University life presents unique challenges that can disrupt sleep patterns and contribute to sleep difficulties. Students often have variable class schedules, early morning commitments, and late-night social activities, making it challenging to maintain a consistent sleep schedule. Additionally, the use of stimulants like caffeine and energy drinks, as well as alcohol consumption, can negatively impact sleep quality. The pressure to perform academically, financial worries, and the stress of living away from home can also take a toll on sleep.
The consequences of sleep deprivation among university students are far-reaching and include impaired cognitive performance, decreased alertness, and a negative impact on mental health. Students suffering from insomnia or sleep deprivation often experience mental health issues such as chronic fatigue, depression, stress, anxiety, and a lower quality of life. The link between sleep and mental health is bidirectional, as mental health issues can also contribute to sleep disturbances, creating a vicious cycle.
Furthermore, sleep deprivation can affect students' academic performance, with studies showing a correlation between poor sleep and lower GPAs. Lack of sleep can hinder learning, memory, and neurocognitive performance, making it more difficult for students to succeed academically. It can also impact their relationships, leading to increased irritability, impaired decision-making, and difficulty maintaining healthy interactions.
Addressing sleep problems among university students is crucial for their overall well-being. This can include improving sleep hygiene, managing stress, and seeking help for underlying mental health issues. By prioritizing sleep and making necessary lifestyle changes, students can improve their mental health, enhance their academic performance, and lead healthier, more productive lives.

Improving sleep hygiene
Sleep deprivation is a common issue for university students, with over 60% reporting that they feel "dragging, tired, or sleepy" at least three days a week. This can have a significant impact on their academic performance, with a direct correlation between sleep deprivation and lower GPAs.
To improve sleep hygiene and overall quality of sleep, university students can implement the following strategies:
Maintain a Consistent Sleep Schedule:
University life often involves variable class schedules, late-night socialising, and early morning commitments, making it challenging to maintain a consistent sleep schedule. However, adhering to a regular sleep and wake-up time, even on weekends, can help regulate your body's internal clock and improve sleep quality.
Create a Conducive Sleep Environment:
Noise from roommates or neighbours can be disruptive, so consider using earplugs or white noise to minimise noise disturbances. Additionally, limit exposure to electronic devices before bed, as the light emitted can reduce melatonin production, disrupting your sleep.
Manage Stress and Stimulants:
Stress is a significant contributor to sleep disturbances. Find healthy ways to manage stress, such as practising relaxation techniques, engaging in physical activity, or seeking counselling services if needed. Additionally, limit the use of stimulants like caffeine and energy drinks, as they can increase sleep onset latency and reduce overall sleep efficiency.
Limit Alcohol Consumption:
While alcohol may help you fall asleep initially, it can disrupt the second half of your sleep, leading to fragmented rest. It can also contribute to sleep disorders like obstructive sleep apnea.
Prioritise Sleep:
Sacrificing sleep to study or socialise may seem necessary at times, but it is essential to recognise the long-term benefits of adequate sleep. Prioritising sleep can improve your academic performance, mood, relationships, and overall health.
By implementing these strategies, university students can improve their sleep hygiene, leading to better rest and overall well-being during their academic journey.
