How Many Hours Should Teenagers Sleep?

A teen’s body’s natural circadian rhythm changes with age. A biological shift in the body’s sleep cycle means that teens struggle to fall asleep by 11 pm. To compensate, they stay up later on the weekends, trying to catch up on sleep during the week. This strategy makes it harder to wake up early on Mondays. Therefore, the question of how many hours a teenager should sleep is crucial for the development of the body.

Teenager age Nighttime sleep (in hours) Total (in hours)
11 years 9.5 9.5
12 years 9.25 9.25
13 years 9.25 9.25
14 years 9 9
15 years 8.75 8.75
16 years 8.5 8.5
17 years 8.25 8.25
18 years 8.25 8.25

School start times

The question is, how much should teenagers sleep before school start times? The answer depends on the type of school and the start time. California, for example, passed a law that requires middle and high schools to start at least eight hours before sunrise. Other states have passed similar legislation. Some of these laws have been successful, but most are not yet universal. Here are some reasons why the earlier start time is beneficial.

As a general rule, teens and adults should get up around 7:30 a.m. to maximize alertness. Teenagers should not go to bed before midnight, so they should be up by 7:30 a.m. To be productive during the day, they should be awake at least two hours before the school day begins. Teenagers also need at least nine hours of sleep each night.

Adolescents’ sleep patterns are influenced by their biological clocks, so starting school too early can cause chronic sleep deprivation. In fact, a sleep researcher says teens typically begin their sleep cycles at night, two hours later than the average person. By starting school at an early hour, teenagers are less likely to get enough sleep, which could lead to depression and poor academic performance.

Although adolescents are biologically wired for a later sleep schedule, studies have shown that starting school later can actually have benefits for them. Studies have suggested that extending the start time of middle and high schools would help students achieve better academic performance. This may even reduce the health problems that accompany sleep deprivation. But most school districts aren’t considering making changes to their start times. In addition, the earlier start time might interfere with childcare for younger siblings. Additionally, teens may stay up later than those who don’t have extracurricular activities.


The question of how much time should teenagers spend on electronics has recently attracted new research. Children are spending longer amounts of time on electronic devices, and sleep deficiency is now a public health concern. The present study examined adolescents’ daytime use of electronics, as well as their use before bedtime. It used data from the youth@hordaland study, a large population-based study from the county of Hordaland in Norway. In the study, adolescents from three age groups participated.

Teenagers are recommended to get between eight and nine hours of sleep a night, but their use of electronic devices has an effect on their sleep. Research has shown that teens who spend four hours or more on their devices before bedtime have a three-and-a-half-hour greater risk of sleeping less than five hours. Even worse, they need more than 60 minutes to fall asleep, whereas adults usually get to bed within 30 minutes.

There are several reasons for this connection. While it is difficult to pinpoint the exact causes, researchers believe that teenagers’ use of electronics can interfere with sleep. They can disrupt sleep cycles by stimulating the nervous system and affecting the body’s internal clock. Regardless of the cause, the results suggest a need for a new study and guidance for parents on electronic media use among teens. And it’s never too early to start setting limits.

One way to limit technology’s influence on sleep is to make the bedroom a screen-free zone. Even though your teenager might use electronics in the bedroom, a room reserved for sleeping is the best place for them to unwind. It’s best to turn them off an hour before bedtime to give their brain the time to shut down. Using blue light filtering applications on electronics can minimize the effect of this technology on their sleep. And remember to stick to a consistent bedtime schedule.


The answer to the question, “How many hours should teenagers sleep with caffeine?” depends on your own lifestyle and needs. Studies show that a moderate amount of caffeine can affect your teen’s behavior. In general, most teens tolerate a daily intake of 50 to 100 milligrams of caffeine without side effects. However, there are certain cases where a higher intake may cause problems. For instance, teens with heart or liver conditions, anxiety, or sleep disorders may be more susceptible to adverse effects of caffeine than healthy teens. Also, sex may play a role in the response to caffeine.

To answer the question, researchers at the Nationwide Children’s Hospital in Boston found that teens who rarely consume caffeine have forty minutes fewer hours of sleep than those who do not. And those who do not consume caffeine at all get one hour less sleep than the national average. However, this figure does not take into account sleep-inducing effects of caffeine on the central nervous system. This finding suggests that adolescents need at least a few hours of sleep a day in order to function properly.

The National Sleep Foundation (NSF) has published research that suggests that teens should not consume more than nine hours of sleep a night. While this number is far from scientific, it shows that caffeine does cause sleep problems in adults. In children, caffeine consumption led to shorter sleep and more disturbed sleep, and increased the number of hours awake during the night. In addition, some adults believe that coffee can stunt the growth of children.

Staying up late on the weekends

Teenagers are different from adults in their sleep cycles. While they may be defiant and drag themselves to wake up in the morning, they are simply following their natural sleep cycle. Teenagers experience a delayed phase change in their sleep, due to a large shift in hormones. This means they may not feel sleepy until two hours after they’ve gone to bed on a weekend night.

A common sleep problem for teenagers is early school starts. Those who go to bed after midnight must wake up early the next morning. In addition, they may only get six to seven hours of sleep at night. Even missing a few hours of sleep each night can result in a noticeable deficit over time. This lack of sleep can negatively impact grades and relationships. Teens who don’t get enough sleep are also at higher risk for accidents, including falling asleep while driving.

While sleep deprivation may be a temporary solution to a temporary lack of sleep, it will ultimately hurt the body and lead to a bigger problem. Staying up late will cause the internal body clock to drift further from the external one, making it difficult for teenagers to fall asleep and wake up on time. Teenagers should stick to the recommended eight-hour bedtime during the week, which is eight hours on weekends.

Teenagers should prioritize their sleep schedule and leave time for study. Setting a daily schedule is hard to do for many teenagers, but it will have lasting benefits. If possible, encourage your teen to get some shut-eye early on Sunday night. However, if they need to study until two in the morning, do not let them stay up until three in the morning. Additionally, parents should limit their teenagers’ involvement in stimulating activities and evening events. Early morning appointments should also be avoided.

Insufficiency of sleep

There are several reasons why the insufficiency of sleep among teens is detrimental to adolescent development. Inadequate sleep disrupts the development of the frontal lobe, which is important for the regulation of impulsive behaviors. Teenagers who do not get enough sleep are more prone to engage in high-risk behaviors like drug use, risky sexual behavior, and fighting. Lack of sleep also affects academic performance.

Teens have numerous responsibilities: schoolwork, sports, community activities, and more. They might be staying up late to complete assignments, meet friends, or get their homework done. The pressure to succeed may also contribute to sleep issues. Insufficiency of sleep among teens is a significant cause of obesity, poor academic performance, and depression. However, addressing the problem is easier said than done. It is important to find out what factors affect adolescent sleep.

The biological causes of insufficiency of sleep among adolescents are numerous. Some of the most common reasons for insufficient sleep include the workload at school, excessive homework load, and early start times. Lack of sleep affects the brain’s ability to function properly and negatively impacts adolescent health. The consequences of sleep deprivation range from poor academic performance to impaired executive functioning. It can even lead to obesity, cardio-metabolic dysfunction, and mood disorders.

The impact of insufficiency of sleep on adolescent development is well documented. Teens who do not sleep enough are 24% more likely to develop depression and are three times more likely to consider suicide. Additionally, those who do not get enough sleep are outpaced academically by their peers with higher grades. On average, teenagers who get adequate sleep also spend an hour more than teens with a D grade.
