Teenagers' sleep requirements
Teenagers need more sleep than younger children because their bodies and minds are growing quickly. They are going through a second stage of cognitive maturation, and this additional sleep supports their developing brain and physical growth spurts.
The average amount of sleep that teenagers get is between 7 and 7.25 hours. However, they need between 8 and 10 hours of sleep per night. Most teens should get 9 to 9.5 hours of sleep per night—that's an hour or so more than they needed at age 10.
There are several reasons why teenagers are not getting enough sleep. Firstly, there is a biological shift in their internal body clock during puberty, causing a delay in their sleep-wake cycle. Secondly, early school start times mean that teenagers have to wake up early, disrupting their natural sleep patterns. Finally, social and school obligations, such as homework, extracurricular activities, and socialising, lead to late bedtimes.
The impact of sleep deprivation on teenagers
Sleep deprivation can have several negative consequences on teenagers' mood, behaviour, cognitive ability, and academic performance. It can also increase the risk of drowsy driving, which is the most likely to occur in the middle of the night and the mid-afternoon.
Tips for helping teenagers get enough sleep
- Maintain a regular sleep schedule, including on weekends.
- Take short naps in the early afternoon.
- Limit screen time and exposure to blue light before bed.
- Avoid caffeine, smoking, alcohol, and drugs, which can disrupt sleep.
- Exercise regularly, but avoid vigorous exercise close to bedtime.
- Create a relaxing bedtime routine and a calm atmosphere in the bedroom.

Sleep deprivation consequences
Sleep is essential for the physical and mental development of teenagers. However, due to various factors, many teens suffer from sleep deprivation, which can have serious consequences for their health, well-being, and safety. Here are some of the potential consequences of sleep deprivation in teenagers:
Cognitive and Emotional Difficulties:
- Sleep-deprived teens may experience difficulties with memory, concentration, and motivation. They may find it hard to stay awake in class and have trouble with academic performance, leading to poor grades.
- Lack of sleep can also affect their decision-making abilities, increasing the likelihood of engaging in risky behaviors such as drunk driving, texting while driving, or not using a seatbelt.
- It can also contribute to mental health issues such as anxiety, depression, and even thoughts of suicide.
Physical Health:
- Sleep plays a vital role in the effective functioning of the body's systems. It supports the immune system, helps regulate hormones, and enables muscle and tissue recovery.
- Sleep deprivation can negatively impact physical development during adolescence, leading to metabolic issues and potentially increasing the risk of diabetes and long-term cardiovascular problems.
- It can also cause slower physical reflexes and increased clumsiness, which may result in accidental injuries.
Accidents and Injuries:
- Sleep deprivation increases the risk of accidents, especially drowsy-driving incidents, as it impairs reaction times.
- It can also lead to an increased number of 'sick days' from school due to tiredness and physical illness.
Behavioral Problems:
- Sleep-deprived teens may exhibit moodiness, aggression, and irritability. They may also be more prone to interpersonal conflicts and have difficulty maintaining healthy relationships with family and friends.
- Sleep deprivation can affect the development of the frontal lobe, which controls impulsive behavior, leading to an increase in risky behaviors.
Social and Emotional Development:
- Sleep plays a role in emotional regulation. Sleep-deprived teens may struggle with managing their emotions and controlling their impulses, leading to a negative spiral of fatigue, labile emotions, and poor decision-making.
- Prolonged sleep loss can negatively impact their social relationships and emotional development, increasing the risk of interpersonal conflicts and mental health issues.

Sleep and development
Sleep is essential for people of all ages, but especially for teenagers who are undergoing profound mental, physical, social, and emotional development. During adolescence, the body's internal clock shifts, causing a natural tendency to stay up later and sleep longer in the morning. This shift can make it difficult for teenagers to fall asleep before 10 or 11 pm, and they may need to sleep until 8 or 9 am. However, with early school start times and busy schedules, teenagers often don't get enough sleep, which can have negative consequences for their health and well-being.
The Importance of Sleep for Teenagers
Sleep plays a crucial role in a teenager's development and overall health. Firstly, it supports their developing brain and physical growth spurts. Secondly, it helps protect them from serious issues such as depression, anxiety, and drug use. Additionally, sleep benefits the brain by promoting attention, memory, and analytical thought, which are essential for academic achievement and learning new skills.
Sleep Recommendations for Teenagers
Experts recommend that teenagers between the ages of 13 and 18 get 8 to 10 hours of sleep per night. However, this can vary depending on the individual, with some teens needing more or less sleep. Maintaining a consistent sleep schedule is crucial, as is creating a relaxing bedtime routine and limiting caffeine and screen time before bed.
Challenges to Getting Enough Sleep
There are several challenges that teenagers face when it comes to getting enough sleep. Early school start times, homework, extracurricular activities, social obligations, and part-time jobs can all contribute to late bedtimes and insufficient sleep. Additionally, the natural shift in their internal body clock can make it difficult for teens to fall asleep early.
Consequences of Sleep Deprivation
Sleep deprivation in teenagers can have a range of negative consequences. It can lead to moodiness, irritability, and difficulty regulating emotions. It can also increase the risk of risky behaviours such as drunk driving, texting while driving, and other dangerous activities. Sleep-deprived teens may also experience problems with attention, memory, decision-making, and creativity, which can impact their academic performance.
Strategies for Improving Sleep
There are several strategies that can help teenagers improve their sleep habits:
- Advocating for later school start times
- Educating teens about the importance of sleep
- Leveraging the natural power of melatonin by dimming lights and reducing screen time before bed
- Creating a consistent bedtime routine and schedule
- Limiting caffeine, nicotine, and other chemical stimulants
- Encouraging regular exercise and a healthy diet
- Maintaining a calm and relaxing atmosphere at bedtime

Sleep disorders
To compensate for lost sleep during the week, teens often sleep in on weekends, which can further disrupt their body clocks and make it harder to fall asleep on Sunday nights and wake up for school on Mondays. This delayed sleep-wake cycle can be severe enough to be diagnosed as delayed sleep phase syndrome or "night owl" syndrome.
Other factors contributing to sleep disorders in teens include busy schedules, pressure to succeed, and the use of electronic devices before bed. The blue light emitted by screens suppresses melatonin production, making it harder to fall asleep. Caffeine consumption, especially in the evenings, and stress from heavy workloads and social commitments can also disrupt sleep.
Some teens may also suffer from underlying sleep disorders such as obstructive sleep apnea, which causes pauses in breathing during sleep, leading to fragmented sleep and daytime sleepiness. Restless legs syndrome, which involves a strong urge to move the limbs when lying down, and narcolepsy, a rare disorder affecting the sleep-wake cycle, are less common but can also affect teens.
Mental health conditions such as anxiety and depression can also impact sleep quality, creating a bidirectional relationship where insufficient sleep contributes to and exacerbates these conditions. Additionally, neurodevelopmental disorders like ADHD and autism spectrum disorder can make it harder for teens to sleep well.
To improve sleep quality, teens can practice good sleep hygiene, including maintaining a consistent sleep schedule, limiting screen time, reducing caffeine intake, and creating a relaxing bedtime routine. Seeking medical advice is also important to identify any underlying causes and craft tailored treatments, which may include cognitive behavioural therapy for insomnia (CBT-I) or, in some cases, medication.

Sleep is vital for people of any age. But especially for teenagers, who are going through a second stage of cognitive development. Sleep supports their developing brain and physical growth spurts. It also helps protect them from serious consequences like depression, drug use, and an increased risk of accidents.
Tips for Infants and Toddlers:
- Keep regular sleep and wake times, within 1-2 hours of each other each day, even on weekends and holidays.
- Make sure your child feels safe at night. Avoid scary TV shows, movies, and computer games. A night light can help your child feel better.
- Check noise and light in your child's bedroom. Blue light from screens suppresses melatonin levels and delays sleepiness.
- Keep digital technology out of your child's room at night.
- Keep the lights dim an hour before bed for children of preschool age and younger.
- Avoid caffeine in the late afternoon and evening.
- Encourage your child to get plenty of natural light during the day, especially in the morning.
Tips for Teenagers:
- Exercise regularly, but not too close to bedtime.
- Avoid caffeine near bedtime.
- Make your bedroom a tech-free zone.
- Establish a bedtime routine, such as reading, listening to music, or spending time with a pet.
- Start the day in the sunshine. Having breakfast outside or by a sunny window helps regulate the body's biological clock.
- Limit screen time before bed.
- Keep your bedroom cool, dark, and quiet.
- Avoid very hard exercise in the evening.
