Sleep is critical for teenagers' emotional and physical health. Teenagers need between 8 and 10 hours of sleep per night, but most get far less than that. This is due to a combination of factors, including a shift in their body clock, early school start times, social and school obligations, and the use of electronic devices before bed. Sleep deprivation can have serious consequences for teens, including poor academic performance, mood changes, and increased risk of car accidents and substance abuse.

What You'll Learn
Teenagers need between 8 and 10 hours of sleep per night
Biological Factors
During puberty, there is a shift in a teenager's body clock, which makes them feel tired later in the evening and able to sleep later in the morning. This is caused by a change in the release of the brain hormone melatonin, which is released later at night for teens than it is for kids and adults.
Lifestyle Factors
Lifestyle factors also contribute to sleep deprivation in teens. The pressure to do well in school is more intense, and it is harder to get by without studying. Many teens also have part-time jobs, and the use of electronic devices keeps them up late. Social activities and extracurricular commitments can also cut into a teenager's sleep time.
Effects of Sleep Deprivation
Chronic sleep deprivation can have negative effects on a teenager's life, including their mental wellbeing and academic performance. It can cause moodiness, irritability, and aggression, as well as affect their ability to pay attention, learn, and make decisions. Sleep-deprived teens are also at a higher risk of car accidents and are more likely to engage in risk-taking behaviours.
Tips for Improving Sleep
- Maintain a regular sleep schedule, even on weekends.
- Avoid caffeine, especially in the evening.
- Keep the bedroom dark, cool, and free of electronic devices.
- Establish a relaxing bedtime routine, such as reading or taking a warm bath.
- Exercise regularly, but not right before bed.

Early school start times can disrupt sleep
Adolescents are known for not getting enough sleep, with most only getting 6.5-7.5 hours of sleep per night, while they need between 8 and 10 hours. This is due to a biological shift in their internal body clock, which makes them feel tired later in the evening. However, early school start times do not allow them to sleep in, resulting in chronic sleep deprivation.
Early school start times can disrupt the sleep of teenagers, who naturally experience a shift in their sleep schedule after puberty. This shift causes teenagers to feel tired later in the evening and consequently wake up later in the morning. However, early school start times, often as early as 7:00 am, require teenagers to wake up as early as 5:00 am, disrupting their natural sleep patterns.
This nightly "sleep debt" leads to chronic sleep deprivation, which can have significant negative consequences. Sleep-deprived teenagers may experience mood swings, irritability, and difficulty regulating their emotions. They are also more likely to engage in risk-taking behaviours, such as drinking, driving too fast, and other dangerous activities.
In addition, inadequate sleep can lead to problems with attention, memory, decision-making, reaction time, and creativity, all of which are crucial for academic success. Studies have shown that teenagers who get less sleep are more likely to get poor grades, fall asleep in class, and have higher rates of school absences.
Furthermore, drowsy driving is a serious concern, as teenagers are at the highest risk of falling asleep at the wheel, which can lead to accidents and put their safety in jeopardy.
To address this issue, some school districts have delayed school start times, resulting in increased attendance, improved academic performance, and a decrease in car accidents involving students.

Social and school obligations can lead to late bedtimes
Homework, extracurricular activities, and part-time jobs can all contribute to a busy teen's life. They may have sports practices or games that run into the evening, causing them to get home later than usual. Additionally, the pressure of academics and the desire to excel in school can lead to late nights spent studying or completing assignments. Socializing with friends, whether it's hanging out in person or connecting online, can also keep teens up past their bedtimes.
The early start times of high schools can further exacerbate the issue. In many school districts, the transition to high school is accompanied by earlier start times, with some schools starting as early as 7:00 am. This means that teenagers have to wake up as early as 5:00 am to get ready and travel to school, cutting into their sleep time.
The combination of late bedtimes due to social and school obligations, along with early morning commitments, can result in sleep deprivation for 16-year-olds. This lack of sleep can have significant impacts on their mood, behaviour, cognitive ability, and academic performance. It can also increase their risk for car accidents and put them at higher risk for health issues such as obesity and high blood pressure.
To help 16-year-olds get the recommended amount of sleep, which is between 8 and 10 hours per night, it's important to prioritize sleep and create a consistent sleep schedule. This may involve setting boundaries and rules around bedtime, limiting screen time and caffeine intake, and creating a relaxing sleep environment. Educating teens about the importance of sleep and its impact on their overall health and well-being can also motivate them to make sleep a priority.

Screen time can reduce sleep quality
Adolescents are notorious for not getting enough sleep. The average amount of sleep that teenagers get is between 7 and 7 1/4 hours. However, they need between 8 and 10 hours of sleep per night. This is because they experience a natural shift in their circadian rhythm, making it more difficult for them to fall asleep early.
The widespread use of electronic devices has been linked to insufficient sleep in adolescents. The blue light emitted by screens suppresses the production of melatonin, the hormone that induces sleep. This disruption to the natural sleep-wake cycle can lead to increased alertness and delayed sleep onset.
Evening use of electronic devices can also cause psychological stimulation, affecting emotional regulation and increasing the risk of mood disorders. Violent or scary content can be particularly stimulating and should be avoided close to bedtime.
Additionally, screen time can lead to time displacement, where adolescents delay their bedtime to prolong their screen entertainment. This directly reduces the time available for sleep.
To improve sleep quality, it is recommended that screen time is limited, especially in the hour before bedtime. Creating a calming bedtime routine and establishing a consistent sleep schedule can also help.
Tips for Improving Sleep
- Establish a phone-free zone in the bedroom
- Keep the bedroom cool, dark, and quiet
- Encourage a consistent sleep schedule, even on weekends
- Avoid caffeine, especially later in the day
- Monitor what your teenager eats and drinks, reducing caffeine intake
- Encourage afternoon naps (30-45 minutes) instead of sleeping in, which can disrupt the body's sleep cycle

Sleep is critical for a teenager's emotional and physical health
The teenage body's natural rhythm, or internal biological clock, is reset during puberty, making them feel tired later in the evening and wanting to sleep later in the morning. This change is due to the release of the brain hormone melatonin later at night for teens than for children and adults. As a result, teens find it harder to fall asleep early. This natural shift in circadian rhythm is further compounded by early school start times, which means that teens are often sleep-deprived.
Chronic sleep deprivation can have a significant impact on a teenager's life, affecting their mental wellbeing and academic performance. Sleep-deprived teens are more likely to suffer from mood swings, irritability, and frustration. They may also experience problems with attention, memory, decision-making, reaction time, and creativity.
Additionally, lack of sleep can lead to an increased risk of car accidents, mental health issues, and substance abuse. Studies have also found that teens who don't get enough sleep are at a higher risk for obesity, high blood pressure, and other long-term health issues.
To improve sleep for teens, it is recommended to establish a regular sleep schedule, limit screen time before bed, and reduce caffeine intake. Creating a relaxing bedtime routine and a sleep-friendly environment can also promote better sleep. By prioritising sleep, teens can improve their emotional and physical health, as well as their academic and athletic performance.
