Teenagers face a multitude of pressures, from academics and social life to emotional growth. While these challenges are inherent to the teenage experience, one crucial factor frequently enough gets overlooked: sleep.
Studies consistently show that adolescents require 8 to 10 hours of sleep nightly. This isn’t just about feeling rested; its about supporting their physical, cognitive, and emotional well-being. Yet, surprisingly, many teens struggle to hit this target.
Emmet Major, coordinator of Planet Youth, a program dedicated to promoting youth mental health, has observed this trend firsthand. “We could see sleep was an issue,” he states, referring to their 2018 survey where half of the surveyed teenagers weren’t getting adequate sleep. While recent surveys indicate a slight enhancement with 45% now achieving 8 hours or more, Major emphasizes, ”the teen sleep picture is not good.”
Dr. Aoife Dáibhis, a senior clinical psychologist with VHI, underscores the vital importance of sleep for teenagers. “Adolescents have unique sleep needs, different to younger children and adults—because this is one of the most critical periods of development across the lifespan,” she explains.
During adolescence, the brain undergoes notable changes, particularly in the pre-frontal cortex.This region plays a crucial role in decision-making, impulse control, memory consolidation, and attention. Dr. Dáibhis highlights the crucial link between sleep and these developmental processes: “Normal brain maturation is supported by adequate sleep. Sleep consolidates memory and it supports good attention,” she emphasizes.
The benefits of sufficient sleep extend beyond cognitive development. Sleep is essential for physical health too. Growth hormones are released during sleep, and it regulates metabolism. Dr. Dáibhis warns that adolescents who don’t get enough sleep are at a higher risk for obesity and cardiovascular problems later in life.
Perhaps most importantly, sleep plays a vital role in emotional regulation. “We know that deep sleep supports regulation of stress hormones like cortisol,” Dr. Dáibhis notes. Teenagers who consistently get adequate sleep report lower levels of anxiety and depression, and are more likely to engage in healthy behaviors while avoiding risky ones.
Emmet Major’s research at Planet Youth has revealed a strong correlation between inadequate sleep and higher stress levels in teenagers. Just 19% of students getting less than six hours of sleep per night reported low stress levels, compared to 60% of those sleeping over eight hours.These findings underline the critical importance of prioritizing sleep for teenage mental well-being.
The message is clear: prioritizing sleep is not a luxury for teenagers; it’s a necessity. By ensuring our teenagers get the rest they need, we can empower them to navigate the challenges of adolescence with greater resilience, better mental health, and a brighter future.
The Teen Sleep Crisis: A Growing Concern
teenagers are facing a sleep crisis, struggling to get the crucial rest they need for physical and mental well-being. This isn’t just a matter of teenagers being naturally inclined to stay up late; it’s a complex issue fueled by a combination of biological, social, and technological factors.
Research by Planet Youth, a youth health organization, paints a stark picture. The organization’s 2022 survey revealed that only 18% of teenagers consistently get the recommended eight hours of sleep. Even worse, just under a quarter of teens sleeping less than six hours nightly reported feeling good compared to 65% of those who managed eight hours or more. Dr. Máiréad Major, a youth mental health specialist, emphasizes, “I believe the biggest preventable health problem in our teen population is lack of sleep.”
One contributing factor is the natural shift in teenagers’ circadian rhythms. According to Dr.Dáibhis, a sleep expert, teens release melatonin, the sleep hormone, one to two hours later than adults, meaning they might not feel tired until 11 pm, clashing with early school start times.
“They’re getting up early, going to bed later, and they’re taking a while to fall asleep. They’re not getting enough hours, or good enough quality sleep. Their routine is skewed away from what they need,” Dr. Dáibhis explains.
Laura McKitterick,from Jigsaw,Ireland’s youth mental health service,highlights the relentless demands placed on teenagers today. “A lot of adolescents have really exhausting schedules — academic, with homework and study when they get home, social pressures, sports routines and extracurricular activities, not to mention any commuting time that has to be built in. It’s a very demanding schedule.”
Adding to the pressure, the digital age brings its own challenges. Social media and smartphones have become central to teenage life, often blurring the lines between daytime and nighttime. “Their social lives often come alive late into the evening. The most vital thing, especially for those in early adolescence, is their friends and social lives — a lot of which is lived on phones,” McKitterick says.
Planet Youth’s 2022 survey found that 83% of teenagers kept their phones in their bedrooms overnight, a finding echoed in the 2024 survey with a slightly lower 80% reporting the same habit. “Phones in bedrooms is a huge problem. Young people say they need the phone for homework or as an alarm, and it creeps in,” says Dr. Major. “Phones really don’t belong in a bedroom after lights out.”
Beyond the temptation to scroll, smartphones present a constant barrage of notifications that can disrupt sleep. Dr. Major adds, “And phones are really addictive. They keep teens engaged — the pre-frontal cortex is developing through adolescence and they don’t yet have the impulse control to step away as an adult would. So it all competes for the time they should be sleeping — they’re scrolling instead of sleeping.”
Addressing the teen sleep crisis requires a multi-pronged approach, involving parents, educators, and policymakers. Encouraging healthy sleep habits, limiting screen time before bed, and creating a sleep-conducive environment are crucial steps. By understanding the complex factors at play, we can definitely help teenagers get the rest they need to thrive.
Teen Sleep: signs of Trouble and How to Help Your Teen Get a Good Night’s Rest
Adolescence is a time of significant change, and sleep patterns are no exception. Many teens struggle with getting enough sleep,frequently enough prioritizing social connections,extracurricular activities,and academic demands over rest. “I’ve met very conscientious kids who are up during the night supporting friends,” shares sleep expert Dáibhis, highlighting the emotional demands placed on young people.
Recognizing the warning signs is the first step in addressing teen sleep issues. Dáibhis points out,”There are lots” of telltale signs. “Low energy, mood swings and irritability are common, along with physical cues like dark circles under the eyes and a generally pale appearance,” she explains. “if your teen finds it tough to wake up and needs a significant amount of coaxing, that’s another red flag.”
Fortunately, there are steps parents can take to help their teenagers establish healthy sleep hygiene practices. Dáibhis suggests several actionable strategies:
- Maximize daylight Exposure: “Earlier exposure to daylight, such as walking to school, is particularly helpful,” says Dáibhis.
- Embrace Regular Exercise: Physical activity is beneficial, but avoid vigorous exercise too close to bedtime.
- Establish a Consistent Meal Schedule: “If they’re not eating enough,they won’t sleep well either,” emphasizes Dáibhis,stressing the importance of fueling the body properly.
- Avoid Heavy Meals before Bed: Opt for lighter dinners and steer clear of caffeine, nicotine, and energy drinks in the evening.
- Create a Wind-Down Ritual: “Ideally, there should be no devices in the hour before bed,” advises Dáibhis. Encourage relaxation techniques like reading, a warm bath, or gentle stretching.
- Optimize the Sleep Environment: make your teen’s bedroom a sleep sanctuary by ensuring it’s cool, dark, quiet, and comfortable.
- Banish Devices from the Bedroom: “Parents need to enforce this,” insists Dáibhis.While teens may resist, establishing this boundary is crucial for quality sleep.
Dáibhis underscores the long-term impact of healthy sleep habits, stating, “Sleeping well can be part of a behavioral trajectory that starts in adolescence. At this time, young people are at a crossroads where they can develop healthy habits that will serve them well throughout their lives.” It’s never too early to prioritize healthy sleep practices and set your teenager up for success.

Dr. Aoife Dáibhis: Sleep is absolutely vital for teenagers due to the notable physical, cognitive, and emotional changes they’re experiencing. During adolescence, the brain undergoes considerable development, particularly in the pre-frontal cortex, which is responsible for decision-making, impulse control, memory consolidation, and attention. adequate sleep supports normal brain maturation and these developmental processes.
Archyde: How much sleep do teenagers need, and how many are actually getting it?
Dr. Aoife Dáibhis: Teenagers require 8 to 10 hours of sleep per night.However, studies consistently show that many teens struggle to meet this target. According to Planet Youth’s surveys, the sleep picture among teenagers isn’t good. In their 2022 survey, only 18% of teens consistently got the recommended eight hours of sleep.
Archyde: What are the consequences of insufficient sleep for teens?
Dr. Aoife Dáibhis: inadequate sleep can lead to a range of issues for teenagers. It impacts cognitive functions,leading to difficulties with concentration,memory,and decision-making. It also affects emotional regulation, with teens who don’t get enough sleep being more prone to anxiety and depression. Additionally, sleep is crucial for physical health, as growth hormones are released during sleep, and it regulates metabolism. Chronically sleep-deprived teens are at a higher risk for obesity and cardiovascular problems later in life.
Archyde: What role do smartphones play in this sleep crisis?
Dr. Aoife Dáibhis: Smartphones are a major contributors to the teen sleep crisis. The blue light emitted by screens can disrupt the body’s production of melatonin, a hormone that signals to the brain that it’s time to sleep. the constant barrage of notifications also disrupts sleep and can make it challenging for teens to relax and fall asleep. Moreover, the engaging and addictive nature of smartphones can lead to delayed bedtimes and reduced overall sleep time.
