Sleep Deprivation: A Teen's Guide To Understanding The Risks

what happens when you lose sleep as a teen

Sleep is incredibly important for teenagers, whose developing brains need between eight and ten hours of sleep every night. However, due to a combination of biology, screen time, societal expectations, and early school start times, teens are often sleep-deprived. This can have a range of negative consequences, including impaired cognitive function, poor academic performance, drowsy-driving incidents, anxiety, depression, and even suicidal thoughts. Sleep deprivation can also cause teens to be moody, irritable, and more likely to engage in risk-taking behaviors.

Teens need 8-10 hours of sleep per night

Sleep is critical for teens to function at their best. Most teens require 8 to 10 hours of sleep each night, but studies indicate that nearly 70% fall short of this recommendation. Teenagers experience a shift in their circadian rhythm, making it challenging for them to fall asleep before 11 pm. This, coupled with early school start times and a packed schedule, contributes to the pervasive sleep deprivation among this age group.

The consequences of insufficient sleep in teens are significant. Sleep-deprived teens may find themselves in a perpetual haze, impairing their mood, cognitive abilities, emotional regulation, learning capacity, and relationships with adults. They may also exhibit impulsive or reckless behaviour, such as engaging in unprotected sex or reckless driving, due to poor judgment and a lack of impulse control.

To promote healthy sleep habits in teens, it's essential to address their unique sleep patterns and external factors. Here are some strategies to ensure teens get the recommended 8 to 10 hours of sleep:

  • Establish a relaxing bedtime routine: This could include activities such as taking a bath, having a hot milky drink, meditation, mindfulness practices, or gentle yoga.
  • Limit screen time before bed: The blue light emitted by electronic devices suppresses melatonin production, disrupting sleep. Encourage teens to keep their phones and other electronic devices outside the bedroom at night.
  • Create a sleep-conducive environment: Ensure the bedroom is dark, slightly cool, and free from excessive noise. Consider using blackout shades, a sleep mask, or a white-noise machine to create an ideal sleep environment.
  • Avoid stimulants and recreational drugs: Caffeine, nicotine, and alcohol can disrupt sleep and impact overall sleep quality. Encourage teens to limit their consumption, especially close to bedtime.
  • Prioritize regular exercise: Exercise can improve sleep quality, but avoid vigorous workouts right before bed, as they may make it harder to fall asleep.
  • Manage stress and anxiety: Stress and anxiety can interfere with sleep. Encourage teens to address their worries and practice stress management techniques, such as deep breathing or journaling.
  • Consult a healthcare professional: If sleep issues persist, consider seeking advice from a healthcare provider. They can help identify any underlying sleep disorders or mental health concerns that may be impacting sleep.

Sleep deprivation affects mood, thinking, reaction, learning, and impulse control

Sleep deprivation can have a significant impact on various aspects of a teenager's life, including their mood, thinking, reaction, learning, and impulse control.

Teens who don't get enough sleep may experience a perpetual cloud or haze, as described by sleep expert Mary Carskadon, PhD. This haze can negatively affect their mood, leaving them feeling irritable, cranky, or emotional. It can also impair their thinking and cognitive abilities, making it difficult to concentrate, form coherent thoughts, or step back and gain perspective.

Additionally, sleep deprivation can affect a teen's reaction time and coordination, increasing the risk of accidental injuries and traffic accidents. Their learning may also be impacted, leading to poor grades and an inability to retain information effectively.

Sleep-deprived teens often struggle with impulse control and may engage in risky behaviours such as reckless driving, substance use, or unprotected sex. They may also experience increased anxiety, depression, and even suicidal thoughts.

The effects of sleep deprivation on teens can be mitigated by improving sleep hygiene, which includes creating a relaxing sleep environment, establishing a consistent bedtime routine, and budgeting sufficient time for sleep (typically 8-10 hours for teens). Adjusting their body clock to match their natural tendency to stay up late and sleep longer in the morning can also help. However, this adjustment should be done gradually and in consultation with a doctor.

Lack of sleep can cause reckless behaviour and poor decision-making

Sleep deprivation in teens can have a range of negative consequences, including reckless behaviour and poor decision-making. It is important to understand the impact of sleep loss on teenage behaviour and overall well-being.

Teens typically need 8 to 10 hours of sleep each night for optimal health and brain development. However, studies indicate that a significant proportion of teens are chronically sleep-deprived. This lack of sleep can put them in a perpetual haze, impairing their ability to think clearly, react appropriately, and regulate their emotions effectively.

Sleep-deprived teens often experience difficulties with impulse control and may engage in risky behaviours such as reckless driving, substance use, and unprotected sex. They may also struggle with decision-making, leading to poor choices and potential negative outcomes. Additionally, sleep loss can increase the likelihood of interpersonal conflicts and contribute to mental health issues such as anxiety, depression, and even suicidal thoughts.

The shift in melatonin production during adolescence contributes to the tendency for teens to stay up later and sleep longer in the morning. This natural shift in their circadian rhythm often conflicts with early school start times, compressing their sleep time and disrupting their natural sleep patterns. As a result, teens may find themselves in a constant state of sleep deprivation, impairing their overall functioning and increasing the risk of reckless behaviour.

To mitigate these risks, it is crucial for teens and their caregivers to prioritize healthy sleep habits. This includes maintaining a consistent sleep schedule, creating a relaxing bedtime routine, limiting screen time before bed, and ensuring a comfortable sleep environment. By improving sleep hygiene and addressing sleep deprivation, teens can reduce the likelihood of engaging in reckless behaviour and making poor decisions.

Sleep disorders and mental health problems can cause insomnia

Sleep is critical for teens, whose developing brains require 8 to 10 hours of sleep each night. However, close to 70% of teens do not get adequate sleep, which can have significant physical, mental, and behavioural repercussions. Sleep-deprived teens may experience a “haze” or "cloud" that negatively impacts their mood, ability to think, react, regulate emotions, learn, and get along with others. This can lead to reckless behaviour, including unprotected sex and reckless driving, as well as an increased risk of accidents and injuries.

Sleep disorders and mental health problems can have a bidirectional relationship with insomnia. Insomnia, characterised by difficulty falling asleep, staying asleep, or waking up too early, can be both a symptom and a contributor to mental health disorders. Adolescents with insomnia are at an increased risk of developing mental health difficulties later in life, including anxiety and depression. The presence of insomnia symptoms has been associated with a higher risk of suicidal ideation, planning, and attempts. Insomnia can also exacerbate existing mental health issues, forming a vicious cycle that further impairs sleep.

Teens with insomnia may experience biologically detrimental alterations, including brain cortical malfunctioning, systemic inflammation, and metabolic changes. Additionally, insomnia can be a symptom of underlying mental health disorders such as anxiety and depression. Sleep-deprived teens are more likely to use stimulants like caffeine and nicotine and are at a higher risk of engaging in substance use and risky behaviours.

It is important to note that insomnia is not limited to difficulty falling asleep but can also include restless sleep or waking up feeling unrefreshed. If insomnia occurs frequently and impacts daily functioning, it is essential to seek professional help. Cognitive-behavioural therapy for insomnia (CBT-I) is a recognised first-line treatment that educates individuals about sleep and helps change sleep-related behaviours and thought patterns.

To promote healthy sleep habits in teens, it is crucial to create a comfortable sleeping environment, minimise screen time before bed, and establish a relaxing bedtime routine. Encouraging teens to take afternoon naps and adjusting their body clocks to accommodate their natural inclination for later sleep and wake times can also be beneficial. However, it is important to prioritise consistent sleep schedules and avoid the accumulation of sleep debt during the week.

Bright lights and blue light from devices delay the release of melatonin

Bright lights and blue light from devices can delay the release of melatonin, the sleep hormone. During the teenage years, the body's internal sleep clock is reset to fall asleep later at night and wake up later in the morning. This is due to a shift in the production of melatonin, which is made later at night in teens compared to children and adults.

Bright lights and blue light exposure can further delay the release of melatonin, making it even harder for teens to fall asleep. This can contribute to sleep deprivation, which is already a common issue for teenagers.

The effects of chronic sleep deprivation in teens can include an inability to concentrate, poor grades, drowsy-driving incidents, anxiety, depression, thoughts of suicide, and even suicide attempts. Sleep-deprived teens may also exhibit moodiness, recklessness, and impaired impulse control, leading to poor decision-making and accidental injuries.

To mitigate the impact of bright lights and blue light on melatonin production, it is recommended that teens avoid screens such as computers, TVs, and smartphones for at least 30 minutes to an hour before bedtime. Creating a relaxing bedtime routine, such as taking a bath, having a hot drink, or practising meditation or mindfulness, can also help promote better sleep.

Additionally, parents and caregivers can play a role in helping teens establish healthy sleep habits. This includes working with teens to adjust their body clocks, encouraging restful activities in the evening, and discussing ways to increase their nightly sleep quota.
