The transition from childhood to adulthood is marked by significant changes in a child’s life. The hormonal changes affect their physical, mental, and emotional development and can also lead to sleep deprivation and other sleep problems.

In this post, we discuss the importance of sleep on teens and the reasons that affect their sleep. We also give you a few tips on how to help teens sleep better.

Is It Normal For Teenagers To Sleep Late?

As a child reaches adolescence, the body’s internal clock (circadian rhythm) undergoes a biological shift of about two hours, meaning the child who usually sleeps at 9 PM will now sleep at 11 PM.

The production of melatonin, the sleep hormone, takes more time in teenagers than adults, and teens experience sleep drives a bit later than adults. Hence, it is normal for teenagers to sleep late.

This change in circadian rhythm can be further heightened by the teen’s environment and behavior – if this is the case, you should step in. For instance, exposure to bright lights at night, electronic and social stimulation, and late-night social gatherings on the weekends can affect the teen’s bedtime routine and make them sleep late (1) (2) (3).

Recommended Sleeping hours for Teens

The Centers for Disease Control and Prevention (CDC) recommends that teens get about eight to ten hours of sleep per day (4).

Why Is Sleep Important For Teens?

Teens need to get enough sleep as they experience growth spurts and a second developmental stage of cognitive maturation (5). A teen’s body undergoes constant change, which causes stress on the body and mind. Sleep allows the body and mind to recharge. Getting adequate sleep helps support a teen’s developing brain and physical growth spurts and helps improve their physical and mental well-being.

Impact Of Sleep On The Growth And Development Of Teens

Sleep plays a vital role in every aspect of a teen’s life. It impacts their physical, mental, emotional, and social well-being as well as their body responses. Let’s discuss this in detail.

  1. Emotional and mental development: Sleep improves memory, attentiveness, rational thinking, learning, creativity, and decision making, which translates to improved grades at school. Sleep deprivation can cause poor concentration, irritated mood, and emotional instability in teens. Without sleep, the mind slows down, affecting all the body systems.

Sleeplessness is related to anxiety, depression, bipolar disorder, exaggerated emotional reactions, insomnia, mood swings, attention deficit hyperactivity disorder (ADHD), and psychiatric disorders. Sleep directly affects the emotional health and psychological state of a teen, and chronic sleep deprivation is known to trigger negative thinking and emotional vulnerability (6) (7) (8) (9).

  1. Physical health: A deep sleep boosts immunity, helping heal and repair the body, including vital organs, such as the heart and brain. Sleep deficiency is linked to heart problems, high blood pressure, diabetes, obesity, and decreased immunity in teens. Sleep also helps maintain the hormonal balance and hormonal reactions of the body. Thus, insufficient sleep can lead to various health problems (9) (10) (11).
  1. Social well-being: A good mood helps in maintaining healthy relationships. Sleep deprivation can affect the teen’s mood and make them irritated, depressed, and angry, which can further impact social and familial relationships (12) (13).
  1. Body responses: Sleep-deprivation is closely linked to driving accidents and narcolepsy (characterized by excessive sleepiness). The body’s reactions slow down due to sleep deprivation, leading to appetite changes, drowsy driving, and sleep-walking. Sleep-deprived body responses can make an adolescent grow up to be an unhealthy adult (10) (14) (15) (16).

Why Is It Hard For Teens To Get The Recommended Good Sleep?

Sleep deprivation is a common problem in teenagers. The following are some reasons teens are unable to get the recommended sound sleep. These factors could vary in different teenagers (16) (17) (18).

  1. Biological shift of the body’s internal clock
  2. Increased screen time
  3. Notifications and light from mobile phone near the bed
  4. Extracurricular activities and after-school classes
  5. Early or late school, college, and tuition timings
  6. Scool-related stress
  7. Sleep disorders, such as sleep apnea and restless leg syndrome
  8. Over tiredness
  9. Depression and stress
  10. New relationships and day-dreaming
  11. Attending late-night social events
  12. Consuming energy and caffeinated drinks
  13. Uneasiness and discomfort from illness
