Teen Depression & Suicide: Sleep, Early Bedtimes Protect Adolescents

A new study shows that teens who go to bed early and get enough sleep may be less likely to suffer from depression and have suicidal thoughts. The results were published in the Jan. 1 issue of the journal Sleep.

The study involved 15,659 adolescents in grades seven to 12. Data were collected from the teens and their parents.

Teens who reported that they usually sleep for five hours or less per night were 71 percent more likely to suffer from depression. They also were 48 percent more likely to think about committing suicide than teens who reported getting eight hours of nightly sleep. Both depression and suicidal thoughts were less likely in teens who reported that they “usually get enough sleep.”

Teens were more likely to have problems if their parents set a weeknight bedtime of midnight or later. They were 24 percent more likely to suffer from depression than teens who had to go to bed at 10 p.m. or earlier. They also were 20 percent more likely to think about committing suicide.

Teens with a bedtime of 10 p.m. or earlier got the most sleep. They reported sleeping for an average of eight hours and 10 minutes per night. This was 40 minutes more than teens with a bedtime of midnight or later.

“Our results are consistent with the theory that inadequate sleep is a risk factor for depression,” lead author James E. Gangwisch, PhD, told the AASM. “Adequate quality sleep could therefore be a preventative measure against depression and a treatment for depression.”

Seven percent of participants had symptoms of depression. Thirteen percent reported that they seriously thought about committing suicide during the past 12 months.

The NIMH notes that girls are twice as likely as boys to have had a major depressive episode by age 15. But males are much more likely than females to commit suicide. In 2006 suicide was the third-leading cause of death for young people between 15 and 24 years old.

Parents reported setting a wide range of bedtimes. Fifty-four percent of parents reported that their teen had to go to bed by 10 p.m. or earlier on weeknights. Twenty-one percent reported setting a bedtime of 11 p.m. Twenty-five percent reported setting a bedtime of midnight or later.

And most teens complied with the bedtime that their parents set. Seventy percent of teens reported going to bed on time. Overall, teens reported going to bed only about five minutes later on average than their bedtime.

The AASM reports that most teens need a little more than nine hours of sleep each night to feel alert and well rested during the day. But a shift in the timing of their body clock causes teens to feel sleepy later at night. This explains why it can be hard for them to fall asleep before 10 p.m.

In August the Sleep Education Blog reported that a teen’s sleep pattern may be a marker of his or her risk for developing depression. Parents can get tips for teen bed times on SleepEducation.com.

Multiple Factors Hurt Teen Sleep

Only a small percentage of American teens regularly meet their sleep needs. The reason their losing valuable shuteye isn’t quite as simple as sometimes portrayed. A front page article in the Chicago Tribune earlier this week blamed sleep loss on technology such as video games and gadgets. While this is assessment isn’t untrue, it’s just one piece of the puzzle.

Teens have a tendency to be night owls even though they need more sleep than adults. The AASM recommends a minimum of 9 hours of sleep nightly for teens and adolescents. Many schools require teens to wake up very early, sometimes even before their parents. It’s not uncommon to see high school athletes report to morning practice as early as 5 a.m.

Some teens may not be able to go to sleep early enough to get the recommended hours of sleep even if they wanted. Many teens’ circadian systems are incompatible with early morning schedules. An article in the latest issue of Chronobiology International shows evidence that teens are naturally wired to stay awake later especially in the spring and summer.

The study found sleep onset times were delayed when adolescents were exposed to natural light during the evening hours. As the days become longer teens are inclined to stay up later.

The authors compared self-reported bedtimes and sleep durations to the time of sunset. Teens slept went to sleep early and slept longer during shorter winter days. Researchers presume a lighting scheme to reduce teens’ exposure to evening sunlight may help them get to sleep early during longer days.

That alone may not be enough. Turning off the television and Xbox an hour before bedtime may help. Schools too need to make adjustments so more than 21 percent of teens get enough sleep. Pushing start times forward can make students happier, more productive and even keep them out of harm's way.

Teen Depression: Sleep Cycle is a Risk Marker

A recent study shows that a teen’s sleep pattern may be a marker of his or her risk for developing depression.

The study involved 48 teens who were “at risk” for depression; they had a high risk because of a parental history of depression. The at-risk teens were compared with 48 other teens in a control group; these teens had no personal or family history of a mental health problem.

The research team monitored the sleep cycles of the teens for three days. They also used lab tests to measure levels of the hormone cortisol; increased cortisol levels are related to depression in adults. The teens were monitored for up to five years.

Results show that the at-risk teens took less time to enter the stage of rapid eye movement sleep – or REM sleep. They also had more REM sleep and elevated cortisol levels. These teens were more likely to develop depression by the end of the five-year study period.

Previous studies had shown that depressed adults enter REM sleep earlier in the sleep cycle; but it was unclear if this pattern also occurred in teens.

“This study is an initial step in determining baseline measures that differentiate healthy adolescents from those who are likely to develop depression,” lead author Dr. Uma Rao said in a UT Southwestern Medical Center statement.

Rao cautioned that REM sleep and cortisol levels are not diagnostic tools; but they are “vulnerability markers” for depression.

“If we can identify factors such as sleep and cortisol and their role, we could start the prevention process,” she said.

The NIMH reports that depression often occurs along with another disorder in teens; examples include anxiety, eating disorders and substance abuse. By age 15, girls are twice as likely as boys to have had a major depressive episode.

Earlier this year the Sleep Education Blog reported that sleep problems in children may predict the future onset of depression. A study showed that sleep problems at age 8 predict depression at age 10; but depression at age 8 did not predict sleep problems at age 10. The study found a strong genetic link for the presence of sleep problems.

Wired: Technology, Caffeine Keeping Teens Awake at Night

Technology-savvy teens can excel at multi-tasking. They can send text messages, surf the Internet and watch their favorite TV show all at the same time.

But a new study shows that technology may be taking a toll on their sleep. Many teens are staying up too late and consuming too much caffeine. As a result, they’re not getting enough sleep to remain alert during the day.

The study involved students between the ages of 12 and 18 years. They reported how much time after 9 p.m. they use various technological devices.

WebMD reports that watching TV was the most common activity; 82 percent of participants watched TV after 9 p.m. Fifty-five percent reported being online; 44 percent reported talking on the phone; and 42 percent reported listening to an MP3 player. Other common activities were watching movies, text messaging and playing computer games.

Multi-tasking was high; teens used an average of four technological devices after 9 p.m. Teens who did more multi-tasking tended to drink more caffeine.

Only 20 percent of participants got eight to 10 hours of sleep per night; these teens tended to do less multi-tasking after 9 p.m.

Thirty-three percent of teens reported falling asleep in school. Students who fell asleep in class consumed 76 percent more caffeine.

The AASM reports that most teens need a little more than nine hours of sleep each night to feel alert and well rested during the day. But a shift in the timing of their body clock causes teens to feel sleepy later at night. This explains why it can be hard for them to fall asleep before 10 p.m.

The AASM recommends that parents keep the TV and computer out of their teen’s bedroom. Parents also should set a “communication curfew” at night; set a time after which your teen can no longer talk on the phone or send text messages, instant messages or e-mails.

How Moms Influence Teen Sleep

A new study looked for similarities in the sleep patterns of teens and their parents.

The Swiss study involved 293 teens with an average age of almost 18 years; 73 percent were female.

They completed a seven-day sleep log; they also completed questionnaires about their psychological functioning. The teens rated their parents’ sleep and parenting styles.

Results show a correlation between the sleep patterns of the teens and their parents. The study also found that how mothers sleep may have an indirect effect on the sleep of their teens.

Mothers’ poor sleep had a direct impact on their parenting style. This affected the psychological functioning of teens. Parenting style and teens’ mental functioning combined to influence how teens sleep.

The authors concluded that teen sleep problems may mirror an unfavorable parenting style and sleep complaints among mothers. Understanding this relationship could improve family counseling and treatment of teen sleep complaints.

In August the Sleep Education Blog reported that a teen’s sleep pattern may be a marker of his or her risk for developing depression. Another recent study found that technology use may be taking a toll on the sleep of teens.

Study finds video games cause only mild effect on sleep

Every school night, millions of teens armed with controllers and headsets clash on the virtual battlefield of “Call of Duty.” You would think these adrenaline-fueled gaming sessions would keep teen males wired all night. As it turns out, getting to sleep following an evening of gunfire, explosions and kill counts isn’t much different than it would be after watching nature documentaries.

A new study published in the Journal of Clinical Sleep Medicine concluded video games only have a mild effect on the sleep of older teen males.

Researchers in Australia looked at how long it took a group of male teens to fall asleep after they played the best-selling Playstation 3 video game “Call of Duty 4: Modern Warfare,” in comparison to the Academy Award winning documentary “March of the Penguins.”

The difference was only 4.5 minutes.

A group of 18 teens, all about 16 years old, were subject to two 50-minute experimental sessions. Each time they under the covers in bed, in a dimmed room, with electrodes attached.

It took teens 7.5 minutes to fall asleep after playing the violent video game. When they watched “March of the Penguins” the average was three minutes. About a third of the boys fell asleep during the documentary. Seven teens say they felt less sleepy after they played “Call of Duty.” Two of the teens actually fell asleep faster.

Scientists measured only a small increase in the subjects’ alertness, but no differences in their arousal or quality of sleep.

The findings counter the popular, but mostly anecdotal, belief that it’s hard to sleep after playing video games at night.

But that doesn’t necessarily mean gaming has no effect on sleep. The slight difference in teens’ sleepiness might be enough to keep them playing longer. And many game sessions last a lot longer than an hour.

In extreme cases gaming benders have lasted for days. Just this week in South Korea, the Culture Ministry announced plans to stop minors from playing online games after midnight.

Past research has linked excessive video game playing to loss of sleep. College students addicted to video games sleep about one hour less than their peers.

Sleepy Teens Eat More Fatty Foods and Snacks

Poor sleep habits go hand-in-hand with unhealthy diets for teenagers. A new study shows teens that sleep less than eight hours on weeknights usually eat more fatty foods and snack more often than their well-rested peers.

The high-fat, snack filled diet is a recipe for obesity, especially as female teens as researchers discovered through data analysis.

Short sleep durations may cause a number of small adjustments in eating habits, altogether changing a teenager’s energy balance. Results show teens who slept less than eight hours consumed 2.2 percent more calories from fat and 3.0 percent fewer calories from carbohydrates.

Sleep-deprived teens were also more likely to grab a snack between meals. For each extra hour of sleep the change of consuming a high amount of calories in snacks decreased by 21 percent.

The study examined the diets of 240 teens in Cleveland, Ohio. Wrist actigraphy data indicated only 34 percent of the participating teens slept for more than eight hours per night. Researchers cross-referenced the hours each teen slept with nutrition data, collected in interviews.

The authors of the study say it’s not clear why the relationship between sleep length and eating habits is stronger for females. They speculate teenage girls are more likely to engage in emotional eating. Because the findings were based on correlation, researchers could not determine the cause of the relationship.

Females with poor sleep habits may unhealthy foods, but men potentially face far worse consequences. Men with long-term insomnia are more likely to die.

Sleepy teens engage in more risky activities

Teens who are sleep deprived are at risk for more than just falling asleep in class. A new study by the Centers for Disease Control and Prevention (CDC) shows that sleep-deprived teens are more likely to smoke, drink and fight.

A survey was conducted of more that 12,000 teens. About 68 percent said that on an average school night, they get less than eight hours of sleep. Those students were more likely to be involved in risky health behaviors than students who got more than eight hours of sleep. The behaviors included smoking cigarettes and marijuana, drinking alcohol and getting into a physical fight.

Sleep-deprived students were also more sexually active and less likely to exercise. They also were more likely to feel sad or hopeless and think about committing suicide.

The study was published online by the Preventive Medicine journal.

The American Academy of Sleep Medicine reports that most teens need a little more than nine hours of sleep each night. Is your teen getting enough sleep? Find out by reviewing the signs your teen needs sleep on the Your Sleep website. Read more posts about teens and sleep.

Should Teens Start School Later?

The Washington Post reports that Fairfax County in Virginia is the latest school district to join the debate over school start times. A proposal would change the start time of most high schools in the county from 7:20 a.m. to 8:30 a.m.

The goal is to help sleep-deprived teens get more sleep. Research shows that teen sleep loss is related in part to a biological change that occurs during the teen years.

A shift in the body clock’s timing makes it hard for teens to fall asleep before 11 p.m. As a result teens fail to get enough sleep when they have to get up early for school.

But will teens really get more sleep if school starts later in the morning? Or will they just stay up even later at night?

A new study in the Journal of Clinical Sleep Medicine examined this question. It focused on a Kansas county that changed the high school start time from 7:30 a.m. to 8:30 a.m. Results show that the change had a positive effect.

A higher percentage of students got eight or nine hours of sleep per night. There was a decrease in “catch-up sleep” on weekends. Daytime sleepiness also decreased.

The study also suggests that school start times may be linked to drowsy driving. Crash rates for teen drivers in the county dropped by 16.5 percent in the two years after the change. In the rest of the state teen crash rates increased 7.8 percent.

Changing school start times can be a complex decision. It requires altering bus schedules. It has an impact on after-school sports, activities and jobs. It also affects after-school care for younger children.

But the change may be worth the effort. A study looked at how the change affected more than 12,000 high school students in the Minneapolis Public School District. It found that student attendance and enrollment improved. Students also got an average of five more hours of sleep per week.

So what do you think? Should teens get a later start in the morning?

Social Networks: Teen Drug Use & Sleep Loss

A new study examined the relationship between sleep loss and marijuana use among teens and their friends.

The study used data from the National Longitudinal Study of Adolescent Health. The researchers mapped the social networks of 8,349 teens. The students filled out questionnaires. They also named up to five male and five female friends in their social network.

Students had an average age of 16 years at the start of the study. They reported that they usually got an average of 7.8 hours of sleep per night.

Results show that a teen was 11 percent more likely to report sleeping seven hours or less if a friend usually slept for seven hours or less. This effect increased to 20 percent when the friendship was mutual.

Further analyses found that a teen was 19 percent more likely to use marijuana if a friend usually slept for seven hours or less. Twenty percent of this effect came from the spread of sleep behavior from one person to another.

This effect was additive. The rate of marijuana use increased with each additional friend who was a short sleeper.

"The evidence suggests that poor sleep leads to drug use in adolescents, and that both sleep and drug use spread through social networks,” the authors concluded.

They suggested that poor sleep may promote drug use by affecting how teens make decisions. Poor sleep in teens has been shown to reduce impulse control. They also wrote that poor sleep may affect teen alcohol use in similar ways.

The NIDA reports that marijuana is the most commonly used illegal drug in the U.S. A recent survey found that 42 percent of 12th-graders had tried marijuana at least once. Eighteen percent of 12th graders and 14 percent of 10th graders had used it within the past month.

Last year a study found that childhood sleep problems were more likely to predict early onset of substance use in boys than girls. Sleep problems between 3 and 8 years of age predicted the onset of alcohol, cigarette and marijuana use among boys.

Parents Irate Over School Start Time Trade-off

A large urban school district’s move to accommodate children’s sleep needs seems to have backfired. Many parents are outraged that the Kansas City public schools decided to flip-flop elementary school and high school start times. Young children will be waiting at the bus stop before sunrise while teens get an extra hour of sleep.

District leaders had the students’ best interests in mind when they decided to make the switch. Extensive research links earlier high school start times to lower grades and more auto accidents. Many leading voices in the sleep field have advocated for schools to adjust for teens’ natural night-owl tendencies. Major school districts that pushed forward high school start times reported better grades, attendance and extracurricular participation.

The problems stem from costs. The Kansas City district would have to spend an estimated $15 million to buy new busses and hire drivers if primary and secondary schools started around the same time. District leaders say that is not an option.

The change resolves teen sleep issues but brings new daycare and safety issues for parents of younger children. Kids would finish school earlier in the afternoon, while many parents would still be at work. Parents are also weary over letting their kids stand outside in the dark, “at that time of the morning with weirdos” as one parent put it.

Although the research is not extensive, from a sleep health standpoint most elementary school children are able to adapt to earlier school start times. Younger children need more sleep than their teenage siblings, but are still wired to sleep easily in the early evening.

Teens need an estimated nine hours of sleep per night. That sleep need is difficult for most teens to achieve natural circadian rhythms combined with distractions such as cell phones and video games prevent them from feeling tired until late in the night. Some estimates show less than a quarter of teens get an optimal amount of sleep each night.

With bussing costs in mind there’s one option that’s rarely considered. What if high schools started mid-morning, after the traditional elementary school start times? The school day could run from about 9:30 a.m. to 5:30 p.m. Teens would have plenty of time to sleep in every day and children would get to go to the bus stop while it’s light outside. The main downside is that athletics and extracurricular activities would run late into the evening. What do you think? Are there any other downsides with starting school in the mid-morning?

Teen Smoking & Sleep Problems

A new study from Hong Kong examined the relationship between smoking and sleep problems in teens.

The study involved 29,397 Chinese students. They were between 12 and 18 years old. The students completed a health survey that included questions about sleep.

Results show that current smokers were three times more likely to report snoring than teens who never smoked. They also were three times more likely to have difficulty breathing during sleep.

Current smokers were 45 percent more likely to have trouble maintaining sleep during the night. Teens who smoked only once or a few times were 39 percent more likely to report having insomnia.

In the U.S. the rate of teen smoking has dropped since it peaked in the late 1990s. But it is still a significant problem. Tobacco use is the leading preventable cause of disease, disability and death in the U.S.

The NIDA reports that 20 percent of 12th-graders surveyed in 2008 said they had used cigarettes in the previous month. Smoking also was reported by nearly seven percent of 8th-graders.

Last year a study reported that childhood sleep problems were more likely to predict early onset of substance use in boys than girls. Sleep problems between 3 and 8 years of age predicted the onset of cigarette use.

The AASM reports that smokers may be at higher risk for obstructive sleep apnea. Teens can get help for an ongoing sleep problem at an AASM-accredited sleep center.

Teens & Delayed Sleep Phase Disorder

Some people have a circadian clock that makes them “evening types.” These “owls” have a natural tendency to stay up late at night and sleep late in the morning.

Children tend to become night owls as teens because of a shift in the timing of their circadian clocks. This change causes them to feel sleepy later at night. As a result they also prefer to wake up later in the morning.

But as CNN reported last week, some teens may have an extreme change in the timing of their body clock. They may be unable to fall asleep until late at night or early in the morning. Then they may want to sleep until later morning or early afternoon. This problem is called delayed sleep phase disorder.



Insomnia symptoms can be severe when a person with DSP tries to go to sleep at a “normal” time. Excessive daytime sleepiness also can occur when he or she has to wake up early in the morning.

Teens with DSP can have a hard time in school. It can be difficult for them to conform to an early morning school schedule.

But there are effective treatments for DSP. It can be treated by taking melatonin in the afternoon or early evening. Another option is to use bright light therapy in the morning.

Both treatments can help “re-set” the body clock of a person with DSP. This can help normalize the timing of sleep.

“The way to treat delayed sleep phase is give light, in particular blue light like the light in the sky,” AASM member Dr. Jeffrey Durmer told CNN. “It activates a part of the eye that activates a part of the brain that keeps the circadian rhythm under control.”

DSP treatment should be supervised by a board-certified sleep specialist. It is important to determine the proper timing and dose of treatment that is required.

Get help from a board-certified sleep specialist at an AASM-accredited sleep center near you.

Last month a study reported that teen sleep patterns may be disrupted by a lack of exposure to morning sunlight. The researchers proposed that the problem can be solved by designing better school buildings.

Early School Start Times Endanger Teen Drivers, Study Finds

Teens as a group are notoriously bad drivers, with the highest annual accident and traffic violation rate of any age group in the United States. Parents have good reason to fear for the worst every time their child gets behind the wheel: auto accidents are the leading cause of death for America’s teens.

A recent study in the Journal of Clinical Sleep Medicine is directing some of the blame on schools for creating dangerous driving conditions for teens. The study found that accident rates are 41 percent higher when high school classes begin before 7:30 a.m.

The study compared teen accident rates at two demographically similar neighboring communities in southeast Virginia: Chesapeake and Virginia Beach.

Accident data from 2008 provided by the Virginia Department of Motor Vehicles showed that there were 65.8 auto crashes for every 1,000 teen drivers in Virginia Beach compared to 46.6 for Chesapeake.

The only significant difference, according to the authors, was school start times. Classes started at 7:20 a.m. in Virginia Beach. Students in Chesapeake were able to sleep in an extra hour and twenty minutes because of the 8:40 a.m. start time.

The American Academy of Sleep Medicine reports that the average teen needs more than nine hours of sleep per night. Falling asleep early can be difficult for teens because of natural night-owl tendencies and distractions such as smart phones and video games. As a result, teens often fail to get enough sleep and may drive to school with severe sleep deprivation.

Pushing forward start times for high school students will help them get more sleep, and as a result, make the roads safer. School districts across the United States have taken notice and have moved the opening high school bell to 8 a.m. or later.

AAA Study Finds 2 out of 5 Americans Drive Drowsy

New traffic safety statistics provide a wake-up call for America about the public safety threat that is drowsy driving.

About 1 in 6 fatal accidents involves a drowsy driver, the AAA Foundation for Traffic Safety reports. And there’s a 41 percent chance you’re part of the problem, study results show.

Approximately 2 out of every 5 drivers admit to drifting to sleep behind the wheel at some point in their lives. About 10 percent nodded off while driving within the past year. Alarmingly, half of the survey respondents the incident said it happened on a busy highway.

Drowsy driving is the cause of an estimated 4,400 deadly crashes per year, accounting for 17 percent of all fatal accidents on U.S. roadways. You may think most drowsy driving accidents happen in the pitch black and bleary-eyed overnight hours, but findings show the afternoon rush is actually slightly more risky.

Teens and young adults are most likely to cause drowsy driving accidents. The risk is 78 percent higher compared to middle-aged adults, and may be the symptom of a larger problem.

The American Academy of Sleep Medicine reports teens need more sleep than adults, yet rarely achieve it on school nights. More than a quarter of teens are badly sleep deprived while only about 15 percent of teens sleep 8.5 hours on a given school night. In many cases accumulated sleep debt can be as great as five to 15 hours per week, the equivalent of total sleep deprivation.

In severe cases the effects of sleep deprivation are comparable to alcohol intoxication. Teens’ inexperience at the wheel worsens an already dangerous scenario.

Men cause more drowsy driving-related accidents compared to women. The study doesn’t provide a reason, but men are more likely to have obstructive sleep apnea, a breathing disorder that can wreck your sleep and make it difficult to stay awake and alert in the daytime.

Accidents most often occur within the first hour of driving. Most people don’t realize they may struggle to stay awake towards the beginning of a trip, the study found.

The AASM reports the following are signs you may be too drowsy to drive:

1. Yawning repeatedly
2. Inability to keep your eyes open.
3. You catch yourself “nodding off” and have trouble keeping your head up.
4. Trouble remembering driving the last few miles.
5. You end up too close to cars in front of you.
6. Missing road signs or driving past your turn.
7. Drifting into the other lane of traffic.
8. Drifting onto the “rumble strip” or onto the shoulder of the road.

If you find yourself doing any of the things listed above, pull over and take a nap. Drink a cup of coffee and wait a half hour for the caffeine to enter your bloodstream for the boost in alertness you need to finish the trip.

Always get a full night’s sleep before driving. If you can’t sleep, arrange for a ride from a friend.
Make the right choices before and after you get behind the wheel and avoid being one of the 41 percent of Americans who drive drowsy.

Sleep and High School Start Times: Lessons from Fairfax County

An editorial in today’s Washington Post examines the debate over school start times. It shows just how complex it can be to make changes to daily school schedules.

A proposal in Fairfax County, Va., would change the start time of most high schools in the county from 7:20 a.m. to 8:30 a.m. It appears that there is strong support for a change. But there are also many obstacles.

Money is one concern. In Fairfax County, 169,000 students must be transported to and from school each day. This is both complicated and costly.

The Post reports that Fairfax school officials once estimated that a schedule change could cost up to $40 million. But they found ways to make bus routes more efficient. This led to the current “no-cost” proposal.

Teens and parents may have concerns about starting and ending school later. Will some teens still have time to work on school nights? How will after-school activities be affected? Will the new schedule allow enough time for school teams to practice and play games?

In Fairfax County the group Worried About Keeping Extra-curriculars (WAKE) formed around this issue. Another group called Save Our Sport formed to represent the needs of high-school swim teams and dive teams.

Another huge hurdle for many parents is the issue of day care. Changing the schedule may cause younger children to start and end school earlier. Working parents may have to make new arrangements for the supervision of these children after school.

There also is a debate over the merits of the problem. Scientists report that a biological change causes teens to feel sleepy later at night. Early school start times may prevent them from getting the sleep they need.

Others may argue that teens just need more discipline. They could get more sleep if they would get off the Internet and put down their cell phones earlier at night.

What do you think? Is it worth the effort to change school schedules so teens can get more sleep? Or does making a change cause more problems than it solves?

Update 3/20/09: The Washington Post reports today that the Fairfax County School Board rejected the proposal to delay high school start times by a vote of 10 to 2. According to the article, the board decided that changing the school start times would create too much stress for students and parents.

Less Time to Sleep for Media-Savvy Children & Teens?

A new report shows that children and teens are spending more time using media for entertainment. This increase is driven in large part by access to mobile devices.

The report was released by the Kaiser Family Foundation. It involved a 2009 survey of 2,002 students. They were in the 3rd to 12th grades. Their ages ranged from 8 to 18 years.

The study covered TV, movies, computers, video games, music/audio and print Results were compared with a 2004 survey.

Results show that students reported using entertainment media for more than 53 hours per week. Their average daily recreational media usage was seven hours and 38 minutes. This was an hour and 17 minutes more per day than in 2004.



In the past five years the percentage of students who owned a cell phone increased from 39 percent to 66 percent. Ownership of an iPod or other MP3 player increased from 18 percent to 76 percent.

Only about three in ten students reported that they have rules about how much time they can spend using entertainment media. Media usage dropped by nearly three hours per day when parents set limits.

Seventy-one percent of students reported that they have a TV in their bedroom. Fifty percent said they have a console video game player in their room.

“When children are spending this much time doing anything, we need to understand how it’s affecting them – for good and bad,” Drew Altman, PhD, said in a news release. He is the president and CEO of the Kaiser Family Foundation.

Last year the Sleep Education Blog reported that technology may be taking a toll on teens’ sleep. And studies have examined the relationship between TV viewing and sleep problems in children.

The AASM recommends that parents keep the TV and computer out of their teen’s bedroom. Parents also should set a “communication curfew” at night; set a time after which your teen can no longer talk on the phone or send text messages, instant messages or e-mails.

Delaying High School Start Times in England

One high school in England has delayed its start time by an hour to help students get more sleep, reports The Independent.

The school’s original start time was at 9 a.m. This would seem like a luxury to many U.S. teens who start school before 8 a.m.

Now classes begin at 10 a.m. The school day ends 30 minutes later in the afternoon.

“Here is something that schools can do to improve the health and mental health of their pupils,” headteacher Dr. Paul Kelley told The Independent.

The school doors remain open from 8 a.m. to 5 p.m. This allows extra time for the supervision of students whose parents are at work.

Kelley was advised by Oxford sleep expert Russell Foster, PhD. Foster emphasized that teens have a biological need for more sleep than adults. And they are wired to perform better in the afternoon hours than in the early morning.

"It is time we stopped ignoring the sleep patterns of young adults," Foster told The Independent. “It is cruel to impose a cultural pattern on teenagers that makes them underachieve. Most school regimes force teenagers to function at a time of day that is sub-optimal.”

Earlier this year the Sleep Education Blog reported that teens in Kansas and Minnesota have benefited from starting school later. A proposal to delay high school start times in one Virginia county stirred a strong debate before being rejected.

Amount of sleep time linked to risk of teen suicide

Not getting enough sleep can lead to worrisome side effects such as daytime sleepiness and even memory loss. However, did you know that it can be associated with other consequences such as suicidal ideation (thinking of committing suicide)? Studies have confirmed that long total sleep times and short total sleep times (TSTs) are linked to suicidal ideation among adults. The hypothesis that total sleep times also are risks for teens was recently tested, and the results are published in the Journal of Clinical Sleep Medicine.

Researchers used the Youth Risk Behavior Survey to conduct their study. The survey included school-based and nationally representative samples. Researchers analyzed the link between suicidality and sleep, accounting for age, sex, race and ethnicity, feelings of sadness, and substance abuse.

About 15 percent of students reported suicidal ideation, 10 percent said they had planned suicide, five percent attempted it, and two percent said that their attempt had required treatment. The teens that had five hours of sleep or less had a higher risk of suicidality than those who had a total sleep time of eight hours. The same goes for teens who had 10 hours of sleep or more.

The findings suggest that both short and long TSTs are risk factors for suicidality in teenagers. More studies need to be done to examine whether or not sleep duration is a causal or modifiable risk factor for teens.
