INTRO

Sleep deprivation for students in higher education is a common issue that has several underlying and negative consequences, but there are improvements students can make to reduce its frequency and severity[1]. On average, university students get 6 to 6.9 hours of sleep every night[2]. Based on the Treatment for Sleep Disorders, the recommended amount of sleep needed for college students is around 8 hours. According to Stanford University's Department for the Diagnosis, 68% of college students aren't getting the sleep they need[3].  The causes of sleep deprivation are poor sleep hygiene, biology, use of technology, and use of drugs[4]. The effects can damage the student’s GPA and negatively affect student’s focus and memory[4]. Furthermore, the effects on the individual’s mental health can be harmful too; students can face depression, anxiety, and difficulty maintaining their relationships[4][5]. There are many possible solutions to combat sleep deprivation, including improving bedroom environment, reducing exposure to blue light, and taking naps during the day[4].

Sleep Hygiene:

Inadequate sleep hygiene is one reason why college students experience sleep deprivation[6]. Sleep hygiene is defined as habits or practices that allow for healthy amounts of sleep on a daily basis[6]. Good sleep hygiene habits include keeping a consistent sleep schedule, having a quiet sleep environment, and avoiding the consumption of caffeine and alcohol before sleeping[7].

Technology:

Using technology before falling asleep can affect a student’s sleep pattern[8]. The blue light that is emitted from the screens of phones, computers, and other devices stops the production of melatonin[8]. Melatonin is a hormone that controls the sleep-wake cycle of the circadian rhythm[8]. This reduction of the amount of melatonin produced makes it harder to fall and stay asleep[9]. The National Sleep Foundation conducted a poll in 2011 and reported that approximately 90% of Americans used technology in the hour before bed[10]. The poll noted that young adults and teenagers were more likely to use cell phones, computers, and video game consoles than other adults[10]. Furthermore, 22% of participants reported going to sleep with cell phone ringers on in their bedroom and 10% reported awakenings in at least a few nights per week due to their cell phones' ringers[10]. Among those with the cell phone ringers on, being awakened by their cell phone was correlated to difficulty sustaining sleep[10].

According to Elizabeth B. Dowdell and Brianne Q. Clayton, sleep-deprived college students performed significantly worse than peers who had adequate sleep on cognitive skills.[11] Furthermore, the sleep-deprived students were not aware of the extent to which sleep deprivation negatively affects their ability to complete cognitive tasks.[11] Research has shown that individuals with excessive technology use in the bedroom have later bedtimes and tend to sleep later in the morning.[11] The reliance on technology in the bedroom, which should be associated only with sleep, creates difficulty separating waking and sleeping activities.[11] When measuring the amount of sleep during the week compared to the weekend, students with four or more technological devices in their bedroom had significantly less sleep compared to those with three or fewer devices.[11] Since many students do not utilize a do not disturb mode or silence their phones at night, each notification and alert from their phones disrupts their sleep in terms of quality and duration.[11]

Biology:

Several recent studies have shown that adolescents undergo a change in their circadian cycle which shifts sleep times later into the night.[12] This change seems to occur during puberty, extending well into adulthood.[12] The delay in sleep cycles clashes with the structured early morning schedules of students due to early classes or work and the total amount of sleep time is greatly reduced.[12] There has been a push in many educational systems for a later start time to help increase the available time for sleep in adolescents due to these biological changes.[12]

Drugs/Alcohol:

   Caffeine:

A study from the University of Kentucky depicted that more than 78% of college freshmen consume above the recommended amount of caffeine each day[13]. In a study from the Henry Ford Hospital's Sleep and Research Center and Wayne State College of Medicine, they discovered that caffeine consumed within six hours of bedtime can significantly disrupt sleep.[14] Participants in this study who consumed caffeine right before bedtime, three hours before bedtime, and six hours before bedtime all experienced a shorter night's sleep, lower sleep quality, and spent more time awake at night.[14]

   Adderall:

   Adderall is a drug that affects the central nervous system and is prescribed to individuals with attention deficit hyperactivity disorder (ADHD) and/or narcolepsy.[15] Adderall is a highly abused substance amongst students in higher education because it prevents the reuptake of dopamine, allowing college students to stay up all day or night and remain alert.[15] The effects of recreational use are exhaustion and an accumulation of “sleep debt.”[15] Furthermore, frequent use of adderall during the day and night can lead to sleep deprivation and insomnia.[15]

Alcohol:

   College students who consume moderate to severe amounts of alcohol are increasingly likely to face lower quality of sleep.[16] A study published in Behavioral Sleep Medicine showed that significant alcohol use can lead to “lower sleep duration, greater sleep schedule irregularity, bedtime delay, weekend oversleeping, and sleep-related impairment.”[17] Furthermore, increasing alcohol consumption may lead to the student falling asleep faster, but the student will face sleep disturbance.[16] A student who consumes alcohol may sleep for the normal 7-8 hours, but the sleep quality will be lower than an individual who stayed sober.[16]

Physical

Drowsiness

Sleep deprivation causes drowsiness, which can affect students in higher education  in their classes and poses a risk for students who commute by car to their classes. Many students commute by car to their classes from their homes; at the Ohio State University, close to 30% of students commute.[1][2] Individuals with less than 6 hours of sleep are the most likely to fall asleep at the wheel [3]and with the average university students getting that amount of sleep[4], the dangers are a real factor for students. Once a student is in class, sleep deprivation will affect their ability to stay awake in class.  Over 50% of students have fallen asleep in class. [5]

Attention and Memory

Even if a student is staying awake in class, their ability to pay attention in class is severely diminished. 23.2% of students who don’t get enough sleep every night report that they have trouble being able to concentrate on things.[6] Not focusing in class will cause the student to struggle on learning the material and can lead to more sleep deprivation from spending more time on homework.  Lack of sleep also affects the forming of memories. Studies show REM sleep is involved in creating memories related to complex information and “students not getting enough sleep will have trouble committing their classes material to memory and learn slower”.[7] Forgetfulness is another symptom of sleep deprivation, and can be disproportionately harmful, especially during an exam when memory is paramount. Without adequate sleep, the neurons “can no longer function to coordinate information properly, and students lose the ability to access previously learned information. [7] A study of graduate pharmacy students showed 81.7% of students failed to get 7 hours of sleep on the night before an examination. [8]

Eating

Less sleep can also lead to weight gain and obesity due to decreases in the bodies’ energy expenditure and ability to stop eating once full. [9] Combining this with the already subpar diets of college students due to time and monetary constraints can combine to result in weight gain in college students. Weight gain in first year college students is a well known phenomenon called the Freshman Fifteen in the US or the Fresher Five in Australia or New Zealand.

Emotional

Mental Health

Insufficient sleep affects students mood by increasing irritability and causing more negative emotions. Research shows that sleep deprivation increases amygdala activity which is linked to negative emotions like anger and rage.[10] Anxiety is also a symptom of sleep loss experienced by students.  Lack of sleep amplified anxiety in people who already worried more.[11] A survey of college students in 2018 showed 63% of students felt “overwhelming anxiety”. Depression has also been linked to sleeplessness; in a study of 1,000 young adults, those with sleep issues were four times more likely to develop depression [12]. These symptoms are bi-directional, anxiety and depression have been shown to cause sleeplessness, meaning these symptoms can compound.[13]

Relationships

The effects of sleeplessness also affect relationships among college students. An Ohio State University study showed that couples that both got less than 7 hours of sleep interacted in a more hostile way. [14]They also are less successful at resolving conflicts when they do come up [14]. This is an effect from the irritability and impaired decision-making exhibited by students with sleep deprivation [14]. Sleep deprivation also has been shown to reduce feelings of gratitude, which is an integral part of a healthy relationship.[15]

Academic

GPA

Not getting enough sleep has been shown to affect student’s GPA by up to a .02 drop for every night of the week a student sleeps poorly.[16] The effects of lack of sleep were similar to that of binge drinking or abusive relationships on students' GPA and likeliness to drop classes. [16] All the previously mentioned symptoms of lack of sleep contribute to the drop in GPA, from lack of focus affecting students classwork to decreased motivation leading to less hours of studying.

Social Withdrawal

Sleep deprivation also leads to social withdrawal due to increased feelings of loneliness and social isolation [17]. Social interaction is an important part of the lives of students in higher education to remain emotionally stable [17].  Over 64% of students in a 2017 survey of 48,000 college students found 64% had felt lonely in the past year [17]. The lack of social interaction has also been linked to higher levels of anxiety and depression, which negatively affect students [17]. Social withdrawal also negatively affects college students’ social lives because when they feel drowsy they are less likely to seek out new experiences, an integral part of a student’s time in higher education [17].

Establishing Circadian Rhythm and Reducing Blue Light

Circadian rhythm is the bodies’ system to internally monitor and regulate sleep and waking hours in an approximately 24 hour period. [1G] Sleeping a consistent number of hours will reduce feelings of drowsiness throughout the day, especially due to the large amount of sleep needed for students. [2G] Going to sleep at consistent times can be also just as important as sleeping the same number of hours. [3G] Students with consistent sleeping schedules had better grades on average than students with irregular sleep schedules in a study conducted by Brigham and Women’s Hospital [3G]. Schedule changes may impact circadian rhythm, and will take time to adjust to. [3G]

Most modern technology with screens emit blue light, which has the ability to impact and shift circadian rhythms by tricking the body’s response to normal changes in light.  Exposure to blue light has the ability to suppress melatonin, a hormone that helps prepare our body for sleep. [5G] Exposure in the early evening causes a delay to release that melatonin and therefore impacts our bodies circadian rhythm by shifting it back. [4G]

Naps

Napping can be an emergency measure used to help improve performance in the short term and supplement missing hours of sleep. Naps can have several purposes, most commonly to either to prevent sleepiness or recover from sleepiness when working on a task. [6G] Naps should be 60 to 90 minutes for the greatest benefits but any longer they can result in affecting a person’s circadian rhythm. [7G][8G] After napping, a person can wake with “sleep inertia” where a person feels groggy or disoriented after napping. [6G]

Naps have positive short term effects, especially in improving performance and attention. [6G] A study conducted at the University of California, Riverside showed that participants performed similarly on an exam after a 90 minute nap compared to a full eight hours of sleep. [9G] Similarly, NASA conducted a study involving its pilots, where even a short 30 to 40 minute nap improved pilot’s “performance by 34% and their alertness by 54%” [8G].

Improving Bedroom Environment

Students can also improve their bedroom environments to improve how fast they fall asleep and how well they stay asleep.  Studies have shown that outside noise from traffic or other students in dorms near them, and a hotter temperature within the bedroom negatively affect sleep. [10G] Another negative factor is the presence of outside light, which tricks our brain into thinking it is nearing daytime. [11G] It is possible for students to control these factors by changing the thermostat, blocking out sound and darkening the bedroom. Harvard Medical School recommends keeping the bedroom between 60 and 75 degrees Fahrenheit, using a white noise maker or earplugs and using heavy curtains or an eye mask to create the ideal environment [12G]

Sleep Supplements

Sleep supplements may also help improve sleep quality, by providing the body nutrients to get a more restful sleep. Magnesium is a major mineral needed in the human body, and increasing magnesium through supplements or diet can help improve sleep. [13G] Calcium supplements or diet can also help improve sleep as one of the major ingredients for the body to produce melatonin. [14G] Melatonin can also be taken directly to improve sleep, however consultation with a doctor is recommended before hand. [15G] Additionally, there have been other supplements like glycine, Valerian root, and L-theanine that may help improve sleep quality and the ability to fall asleep. [16G] Before taking any sleep aids, talk to a doctor.
