Sleep is critical for teenagers, who require more sleep than adults. However, many adolescents suffer from sleep deprivation due to a combination of biology, technology, and the demands of school and extracurricular activities. Teenagers' natural circadian rhythm makes them inclined to stay up later and sleep longer in the morning, which is often incompatible with early school start times. This results in a “sleep debt” that can have negative consequences on their mental health and academic performance. While parents can help their teenagers improve their sleep habits by setting appropriate bedtimes and limiting screen time, systemic changes such as later school start times and reduced homework loads are also necessary to address this issue.

What You'll Learn

Teenagers need between 8 and 10 hours of sleep per night
Puberty hormones shift the teenager's body clock forward by about one or two hours, making them sleepier one to two hours later. However, early school starts do not allow them to sleep in, resulting in a nightly "sleep debt." Using smartphones and other electronic devices before bed can also reduce sleep time. A study by Vic Health and the Sleep Health Foundation found that teens who put down their smartphones an hour before bed gained an extra 21 minutes of sleep per night, or one hour and 45 minutes over the school week.
To help your teenager get enough sleep, it is important to work with them to avoid overscheduling and balance their commitments. Encourage them to take an afternoon nap after school to recharge, and help them adjust their body clock by choosing a relaxing bedtime routine, such as having a bath and a hot milky drink before bed or practising meditation or mindfulness activities. Gentle yoga may also be beneficial. It is also important to avoid screens such as computers, TV, and smartphones, loud music, and other stimulating activities for at least an hour before bedtime.
Additionally, avoiding stimulants such as coffee, tea, soft drinks, and energy drinks in the evening can promote better sleep. Exposing your eyes to lots of light in the morning can also help wake up your brain. Maintaining a consistent sleep schedule, even on weekends, and exercising regularly can also improve sleep quality.

Screen time before bed reduces sleep time
Sleep is extremely important for teenagers, who require more sleep than adults. Teenagers need between eight and ten hours of sleep every night, but most adolescents only get about 6.5 to 7.5 hours of sleep per night, and some get even less. Sleep deprivation can have a significant impact on a teenager's life, affecting their mental health and academic performance.
Due to the prevalence of screen-based devices, it is common for teenagers to use smartphones and other devices before bedtime. However, this practice reduces sleep time. A study by Vic Health and the Sleep Health Foundation found that teens who put down their smartphones an hour before bed gained an extra 21 minutes of sleep per night, or one hour and 45 minutes over the course of a school week.
The blue light emitted by screens suppresses the production of melatonin, the hormone that regulates sleep. This makes it tougher to fall asleep and can lead to a delay in the circadian rhythm, resulting in a shortened sleep duration. In addition, the constant stimulation from phones and other devices keeps the brain alert and engaged, making it challenging to relax and unwind before sleep. Social media use, in particular, has been linked to depression, anxiety, and poor sleep quality.
To improve sleep quality and duration, it is recommended to limit screen time before bed. This can be achieved by setting a cut-off time, usually at least 30 minutes to two hours before bedtime, and sticking to it. Keeping screens out of the bedroom altogether is ideal, as it helps signal to the brain that the bedroom is a place for relaxation and sleep.
Parents can play a crucial role in helping their teenagers improve their sleep habits. This includes working with teens to avoid overscheduling and balance commitments, as well as encouraging them to take afternoon naps and adopt a relaxing bedtime routine that avoids screens and stimulants.

Teenagers experience a natural shift in their body clock
During puberty, teenagers experience a natural shift in their body clock, or circadian rhythm, which makes them want to go to bed later and sleep later in the morning. This is caused by a change in the production of melatonin, the hormone that promotes sleep, which starts to be released later in the day. This shift is also influenced by a slower accumulation of sleep drive, meaning that teenagers don't start to feel tired until later in the evening.
This natural shift in the body clock can lead to chronic sleep deprivation in teenagers, as they are often unable to get the recommended 8-10 hours of sleep per night due to early school start times and busy schedules. Sleep deprivation can have negative consequences on a teenager's mental wellbeing, increasing their risk of depression, anxiety, and low self-esteem, as well as impacting their academic performance.
To help manage their teenager's sleep schedule, parents can encourage good sleep hygiene practices, such as avoiding screens and other stimulating activities before bed, creating a relaxing bedtime routine, and limiting caffeine intake in the evenings. It is also important to work with teenagers to avoid overscheduling and ensure they are getting enough rest.
While it may be challenging to align a teenager's sleep schedule with their natural body clock, it is important to prioritize their sleep to support their developing brain and physical growth. This may include advocating for later school start times and helping teenagers to prioritize their sleep by modeling good sleep habits and encouraging healthy sleep habits.

Parents can help by limiting screen time and extracurricular activities
Parents can play a crucial role in helping their teenagers develop healthy sleep habits and manage their sleep schedules. One way to do this is by limiting screen time and extracurricular activities. Here are some strategies that parents can use:
Limiting screen time
Excessive screen time can negatively impact a teenager's sleep schedule and overall well-being. The blue light emitted by electronic devices suppresses the production of melatonin, the hormone that promotes sleep. Therefore, it is recommended to limit recreational screen time to less than two hours per day. Parents can encourage their teenagers to set screen timers and lock out certain apps after a specific duration or time of day. Having an open family discussion about screen time and involving parents in screen-related activities can also help set healthy boundaries. Additionally, parents should lead by example by setting their own screen time limits and adopting healthy screen habits.
Encouraging restful activities
Instead of screen time, parents can suggest alternative restful activities in the evening, such as reading, meditation, mindfulness, or gentle yoga. These activities can help calm the mind and prepare the body for sleep.
Reducing extracurricular activities
Teenagers often have busy schedules with school, homework, extracurricular activities, and social commitments, leaving little time for sufficient sleep. Parents can help by assessing their teenager's weekly schedule and trimming activities if they are overcommitted. It is important to prioritize rest and sleep to prevent chronic sleep deprivation, which can impact mental wellbeing and academic performance.
Adjusting the sleep environment
Parents can encourage their teenagers to create a sleep-friendly environment by keeping their bedrooms dark at night and reducing exposure to screens and other stimulating activities before bedtime. This includes limiting the use of computers, TV, smartphones, loud music, and homework within an hour before bedtime.
Promoting afternoon naps
Encouraging a short afternoon nap after school or before dinner can help recharge teenagers and reduce the negative effects of sleep deprivation. However, it is important to ensure that naps do not interfere with their nighttime sleep schedule.
By implementing these strategies, parents can effectively support their teenagers in managing their sleep schedules and improving their overall health and well-being.

Sleep deprivation in teens can lead to accidents
Sleep deprivation in teens can have serious consequences, including an increased risk of accidents. Teenagers require more sleep than adults, with experts recommending 8 to 10 hours of sleep per night for adolescents. However, due to various factors, many teens are not getting enough sleep, leading to a range of negative effects on their health, well-being, and safety.
Biological changes during puberty contribute to teens' tendency to stay up later and sleep longer in the morning. This natural shift in their circadian rhythm makes it challenging for them to fall asleep before 11 p.m. or midnight. Additionally, the production of the sleep-promoting hormone melatonin is delayed in teenagers, further contributing to their tendency to stay up later.
Early school start times, increased homework, extracurricular activities, part-time jobs, and social commitments all contribute to the sleep deprivation epidemic among teens. The demanding schedules of modern teenagers often result in them sacrificing sleep to fulfill their obligations and maintain a social life. This chronic sleep loss can have detrimental effects on their overall health and well-being.
Sleep-deprived teens are at a higher risk of accidents, particularly traffic accidents. Impaired judgment, lack of impulse control, and an increased tendency for reckless behavior can lead to poor decision-making, such as engaging in unprotected sex or reckless driving. The haze of sleep deprivation affects their ability to think clearly, react appropriately, and learn effectively.
Furthermore, sleep deprivation can cause mood swings, anxiety, depression, and even thoughts of suicide. It can also increase the likelihood of substance use, including caffeine, nicotine, and alcohol, as teens attempt to cope with their exhaustion. This toxic mix of sleep deprivation, stress, and other external pressures can have severe consequences for their mental health and overall well-being.
To mitigate these risks, parents can play a crucial role in helping teens establish healthy sleep habits. This includes modeling good sleep habits themselves, such as adhering to a regular sleep schedule, reducing evening caffeine intake, and encouraging restful activities before bedtime. Additionally, advocating for later school start times and working with teens to balance their commitments can help ensure they get sufficient sleep. By taking sleep seriously, parents can help protect their teenagers from the negative consequences of sleep deprivation, including the heightened risk of accidents.
