Why Mental Health Suffers in Sleep-Deprived Teens

We all know how it feels to face the morning when we haven’t gotten enough sleep. Lack of sleep can make us grumpy, unable to focus, and more negative about life in general. Sleep-deprived teens experience these symptoms every day.

Sometimes it can be hard to sort out the reasons for a teen’s moodiness. But no matter what’s going on, too little sleep is likely to make it worse.

In order to help sleep-deprived teens avoid the risks that come with losing sleep, it’s important to understand the signs, the causes, and how to help.

Recognizing Sleep Deprivation in Teens

Here are a few common signs to watch for that might indicate that your teen is not getting enough sleep.

  • Having trouble waking up most mornings
  • Irritability and mood swings
  • Falling asleep easily during the day
  • Trouble concentrating or poor academic performance
  • Sleeping very late on weekends
  • Hyperactivity and nervousness
  • Aggressive behavior

Moreover, the stages of sleep deprivation include acute sleep deprivation, including the symptoms above, and chronic sleep deprivation, which can lead to serious physical and mental health problems.

Why So Many Sleep-Deprived Teens?

For most adolescents, nine hours of sleep is ideal, but very few of them are actually managing that. One study conducted by the Centers for Disease Control showed that less than 9 percent of teens get enough, which answers the question: Why do teenagers sleep so much when they get the chance? Here are some of the reasons why teens are sleep deprived.

  • Screening activities, such as social media, Internet use, video games, and television
  • After-school activities that push study times later
  • Heavy homework loads
  • Schools with early start times
  • Using caffeine or nicotine
  • “Sleep phase delay”—teens’ natural biological clocks keep them up later
  • Stress
  • Light exposure from screens that cues the brain to stay awake.

“Almost all teenagers, as they reach puberty, become walking zombies because they are getting far too little sleep.” —Cornell University psychologist James B. Maas, PhD, leading sleep expert

Sleep-Deprived Teens, Emotion Regulation, and Depression

Lack of rest has a negative impact on the functioning of the emotional regulation circuit of the brain. In studies conducted by Matthew T. Feldner, a professor of psychology at the University of Arkansas, people who lost a night of sleep responded with more emotion to stressors presented in the lab.

One study examined how teenagers reacted during the day when they hadn’t gotten enough sleep. Sleep-deprived teens found stressful situations much more threatening than the more mature study participants.

Furthermore, researchers have found that sleep-deprived teens feel more depressed and anxious. In a study of nearly 28,000 high school students, each hour of lost rest was associated with a 38 percent increase in the risk of feeling sad or hopeless, and a 58 percent increase in suicide attempts.

Another study found that high school seniors were three times more likely to have depression symptoms if they had excessive daytime sleepiness.

Sleep-Deprived Teens, Substance Abuse, and Risky Behavior

Not getting enough sleep can increase teens’ likelihood of using drugs and alcohol. A study published in the Journal of Youth and Adolescence indicates that the disruption of the natural sleep cycle can significantly increase the risk of substance use, by interfering with brain functions that regulate the experience of reward, emotions, and impulsivity.

National Center on Addiction and Substance Abuse statistics show that high school students who get less than eight hours of sleep per night are significantly more likely to use alcohol, smoke marijuana, and become lifetime users of illegal drugs.

Furthermore, sleep-deprived teens tend to engage in risky behaviors, because their impulse control is compromised. A 2015 study found that sleep deprivation is linked to binge drinking, drunk driving, and unprotected sex.

Sleep Deprivation Treatment is About New Habits

Here are some ways for sleep-deprived teens to sleep better and longer.

  • Do physical activity during the day.
  • Make time for short naps.
  • Set an electronic curfew when all devices go off.
  • Create a bedtime routine that includes relaxing activities, such as writing in a journal or listening to music.
  • Keep the bedroom dark and cool.
  • Avoid late-night snacks, which raise and then crash blood sugar, making teens wakeful.
  • Practice yoga and meditation, proven to relax the nervous system.

In summary, a good night’s sleep will help sleep-deprived teens feel better in mind, body, and spirit.
