Teen's body clocks naturally shift to make them feel tired later in the evening, but early school starts do not enable them to sleep in the mornings. Chronic sleep deprivation can have dramatic effects on a teenager's life, including affecting their mental wellbeing and reducing their academic performance at school.
Students who were 6 to 12 years old and who reported sleeping less than 9 hours were considered to not get enough sleep. Teenagers aged 13 to 18 years who reported sleeping less than 8 hours also were considered to not get enough sleep.
Insufficient sleep means not getting enough sleep at night, which can cause several problems including decreased brain development, learning problems and more frequent negative emotions. It can also contribute to weight management problems, growth issues and increased frequency of illnesses.
6-12 years old: should go to sleep between 7:30 and 8:30 pm. 13-18 years old: should go to sleep around 10:00 pm. Bare in mind that once puberty hits, it will be difficult for teenagers to fall asleep until around 11 pm.
A single night of no sleep will not stunt growth. But over the long term, a person's growth may be affected by not getting the full amount of sleep. That's because growth hormone is normally released during sleep.
The longest time a human being has gone without sleep is 11 days and 25 minutes.
Most 13-year-old teens are dealing with the emotional and physical changes that accompany puberty, so it's normal for your teen to feel uncertain, moody, sensitive, and self-conscious at times. During this time, it becomes more important than ever to fit in with peers.
"Staying up all night just once doesn't mean you'll develop one of these health conditions, but engaging in sleep deprivation can encourage poor sleep habits, which, over time, could ultimately impact your overall health," says Dr. Ram.
Teenagers stay up late for three main reasons. First, biological shifts in the production of melatonin, the sleep hormone, make teens stay up later. Second, social media can keep kids up and blue light from devices suppresses melatonin production. Third, having a lot of homework can keep kids up late.
Memory and decision-making are affected. Teens are more likely to make poor decisions and take dangerous risks. Car crashes, substance abuse and suicidality go up. Depression and anxiety increase.

In one brain-imaging study, for example, people who missed a night of sleep and viewed disturbing images had 60% more activity in the amygdala, which is involved in processing fear and anxiety, compared with better-rested volunteers.
It's the regularity that's essential. So while teens should not be sleeping all day, a later bed time and later wake time are fine, as long as they sleep between 8.5 to 9.5 hours a day.
If you can't sleep, don't try to, says Michael Perlis, PhD, director of the behavioral sleep medicine program at the University of Pennsylvania. “The problem with staying in bed for any appreciable amount of time is that this reinforces sleeplessness, physiologically and psychologically,” Perlis says.
The onset of adolescence, generally between 12 and 14, is the hardest age for a teenage girl. The hormones of puberty cause her to feel her emotions more intensely but she has not yet developed the reasoning skills to know how to handle them.
Typically, what people call the “awkward stage” takes place at around ages 11-14, making middle school a tough time for most kids.
This also will be a time when your teen might face peer pressure to use alcohol, tobacco products, and drugs, and to have sex. Other challenges can be eating disorders, depression, and family problems. At this age, teens make more of their own choices about friends, sports, studying, and school.
Adults should stay awake no longer than 17 hours to meet the CDC's sleep recommendation. People tend to experience the adverse effects of sleep deprivation within 24 hours.
After two days of no sleep, you can count on increased irritability, anxiety, foggy memory, and impaired thinking, says Hussam Al-Sharif, MD, a pulmonologist and sleep medicine specialist at the Mayo Clinic in Eau Claire, Wisconsin.
It depends on the cause of the sleep deprivation. If it is due to unrelenting insomnia, seek care at the doctor's office or Urgent Care. If you are seizing or hallucinating, get to the ER.
