A person’s circadian rhythm, more commonly known as their internal clock, starts to change as they near puberty.

Their internal clock starts telling your teen to sleep later and stay in bed longer.

Most teenagers still require between 8 and 10 hours of sleep a night, but their bodies are telling them to go to bed later and later.

Their natural instinct is to go to bed after midnight and sleep late into the following morning.

There are have been studies suggesting that schools open later to accommodate these sleep patterns. Unfortunately, most schools have not adjusted their start times. This is most likely because parents need to get to work early as well.

Pushing For Independence

Stress-Induced Insomnia

stress can cause teens to stay up too late

Many things can cause insomnia. These include physical discomfort (blocked nose or a headache), emotional issues (like family problems or relationship difficulties), and even a room that’s too hot, cold, bright, or noisy.

However, the most common cause of insomnia is stress.

It’s common for teenagers to have insomnia from time to time. Unfortunately, insomnia can become worse when we worry about it.

Insomnia can become chronic when a teen becomes anxious about not sleeping or worries about feeling tired the next day. Doctors refer to this as psychophysiologic insomnia.

Having night owl tendencies is entirely normal, but ensure that your child understands how that affects their day-to-day activities.

Not getting enough sleep can negatively affect their lives. Teens who don’t get enough sleep are more likely to;

  • Be overweight.
  • Not engage in regular physical activity.
  • Feel depressed.
  • Engage in risky behaviors like drinking, smoking, and using drugs.
  • Perform poorly in school.

Is it a problem that teens stay up so late?

Key Takeaways:

  • Puberty typically causes the circadian rhythm to tell the body to stay up later.
  • Staying up late allows kids to feel like they have alone time to express themselves and find individuality.
  • Social media and bright screens make it hard to fall asleep at night. It disrupts the brain’s natural signals that tell us that it is nighttime.
  • Stress can cause insomnia, as well as other physical or psychological causes.
  • Too much homework could be a cause for teens to need to stay up later in order to complete their tasks.

Psychologist Nigel Latta discussed the matter of this later shifting sleep pattern with concerned parents on Facebook stating, “Don’t worry if they live the vampire lifestyle of young people,” the Wall Street Journal reports. “If your kids want to go to bed at 4 a.m. and get up at 2 p.m. then that’s just fine,” he added. “Biologically, that’s where their brains are at anyway.”
