What Causes Sunday Night Insomnia and What Can Help?

By Brandon Peters, MD

It’s been a great weekend and now it’s time to settle into bed to get a good night of sleep before the busy week ahead. After waiting for a few minutes, you start to get a little anxious: you aren’t falling asleep. You start to worry about your function the next day. Then you realize that trouble falling asleep seems to occur every Sunday night. What causes Sunday night insomnia? Learn about some of the contributing factors, including sleeping in, taking naps, caffeine or alcohol use, and anxiety about the week ahead. By identifying and resolving some of the causes, you can finally get to sleep on Sunday nights easily without feeling dread for Monday morning.

Anticipating the Week of Ahead May Provoke Anxiety

What makes Sunday night so special? Of all the nights of the week, it seems to be mostly commonly associated with difficulty falling asleep that characterizes insomnia. Insomnia is defined as trouble falling or staying asleep. When it takes more than 20 to 30 minutes to drift off, this may be a sign of a problem.

There are lots of potential causes of insomnia. When it occurs, anxiety may make it worse. Pressure to fall asleep, or even the slightest focus on it, makes it nearly impossible to doze off. Sunday night may be the time that you start to think about the week ahead. If you hate your job, or if it is stressful, you may approach the week with dread. You might think about the coworkers who drive you crazy. You might ruminate on the projects that seem overwhelming. You might ponder the biggest stressors that you face in the week ahead. None of these thoughts will be conducive to falling asleep.

It may be helpful to use scheduled worry time or relaxation techniques to relieve this stress. You may be able to distract yourself from these thoughts, and fall asleep more easily. If you have persistent anxiety, you may need further help with the use of medication or psychotherapy from a counselor.

Weekend Sleep Patterns May Worsen Sleep Initiation

There is also good evidence that changes in the sleep patterns of the weekend may make it harder to fall asleep on Sunday night. It is very common to be sleep deprived during the week. You may get to bed too late or you may have to wake early. Getting the children ready for school, or making the commute to work, may prompt an earlier wake time. You may get to bed to late due to projects that delay your bedtime. As a result, you may note meet your individual sleep needs during the week. Each night, you may short yourself a little. Night after night, your desire for sleep grows stronger. When Saturday morning rolls around, you may sleep in. You “catch up” on lost sleep and pay off the accumulated sleep debt. If you don’t get up early Sunday morning, the same indulgence may recur. How does this impact sleep?

Our sleep is enhanced through two processes: homeostatic sleep drive and circadian rhythm. The sleep drive is the desire for sleep that builds the longer we stay awake. If you were to stay awake for 30 hours, at the end of 30 hours you would be very sleepy, and fall asleep very quickly. You would probably sleep longer and deeper than you normally would. All wakefulness builds this desire for sleep. Conversely, if you sleep, you diminish the sleep drive. By sleeping in, there is a delay in starting to build the desire for sleep. It is almost like going to bed early. If you sleep in 2 or 3 hours on the weekend, it’s like going to bed that much earlier. If your bedtime is normally at 11 PM, but you crawl into bed at 8 PM, is it any wonder that you can’t fall asleep?

Another contribution to poor sleep on Sunday night is our circadian rhythm. We have a natural tendency toward sleep that is synchronized to the day-night patterns of light and darkness. This is reinforced by our genetics as well as morning light exposure. By delaying the wake time, and getting light to our suprachiasmatic nucleus in the brain a little later, the pattern shifts. It makes it harder for us to wake up and harder for us to fall asleep.

Our bodies respond best to regular patterns, and this includes the pattern of sleep and wakefulness. Keep a regular wake time (with an alarm, if needed), even on the weekends. Go to bed when you feel sleepy, but try to get 7 to 8 hours of sleep through the week to meet your sleep needs. Try to avoid catching up on sleep on the weekend; get enough sleep every night to feel rested.

Afternoon Naps May Diminish Your Ability to Fall Asleep

Weekends are when we can most easily indulge in a nap. Though these don’t usually occur in the morning, they may frequently interrupt the afternoon. Imagine how often you have seen someone dozing on a lazy Sunday afternoon! Sports, movies, and reading seem perfectly paired for dozing on the weekends. Unfortunately, naps can diminish the drive for sleep.

Try to avoid taking prolonged naps, especially if you have difficulty falling asleep at night. Naps lasting 2 hours or more are especially problematic. (These naps may also be sign of a sleep disorder, such as sleep apnea.) As much as possible limit naps to shorter periods, perhaps 15 to 20 minutes. These can be refreshing, without impacting sleep at night. In addition, try to time the naps to mid-afternoon and avoid sleeping in the late afternoon or evening. Falling asleep in the hours before bedtime will make it especially difficult to get to sleep.

If your insomnia is especially entrenched, cut out the naps completely until your sleep improves.

Selecting a Bedtime and Going to Bed Sleepy

As noted above, try to keep a regular sleep schedule, including week nights and weekend nights. By going to bed at the same time every night, you will fall asleep more easily. It is also important to listen to your body and go to bed when you are feeling sleepy.

Sleepiness or drowsiness is different that fatigue, tiredness, or exhaustion. One can feel exhausted, and not fall asleep. Sleepiness is the strong desire for sleep that immediately precedes its onset. It may be associated with heavy eyelids, a warm sensation in the body, and loss of focus in vision.

Go to bed when you feel sleepy, including on the weekends. Don’t choose an optimistic bedtime based on when you would like to fall asleep. If you need to adjust your schedule, it is actually easier to change your wake time with an alarm. Subsequently adjust your bedtime earlier to correspond with when you are feeling sleepy. Insomnia is more likely to occur if you crawl into bed too early to get enough sleep to start your week.

If you are not falling asleep, observe stimulus control. Get up after 15 minutes, do something else relaxing, and come back to bed when you are feeling more sleepy.

Decreased Physical Activity and Consumption of Alcohol and Caffeine

There are other things that can impact your ability to fall asleep. These include changes in physical activity and the varying consumption of alcohol and caffeine.

Some people have very physical jobs. The weekends might be their opportunity to recover and rest. Decreased physical activity, including exercise, on the weekend may make it heard to fall asleep. As much as possible, try to maintain similar levels of exercise on the weekend (or even increase them, if possible).

Alcohol may enhance adenosine levels and increase the desire for sleep. Unfortunately, it is metabolized very quickly. The levels drop, and the desire for sleep disappears. Avoid alcohol intake in the hours before bedtime. Importantly, do not use alcohol as a nightcap.

Caffeine consumption can also impair our ability to sleep. Some people are very sensitive, and caffeine found in coffee, tea, soda pop, energy drinks, or chocolate should be avoided after noon. In others, reducing intake after mid-afternoon may be sufficient. If you have insomnia, try eliminating late consumption of caffeine to learn if it is impacting you.

Final Considerations for Sunday Night Insomnia

When difficulty falling asleep persists, consider other potential causes of Sunday night insomnia. Are you reluctant to go to bed because it means ending the weekend? Are you avoiding the stress of the work week? Is it time to make serious changes in your life to relieve stress?

If your insomnia persists, consider speaking with a sleep specialist about treatment options that may be helpful, including cognitive behavioral therapy for insomnia (CBTI). In rare cases, the use a sleeping pill on Sunday nights may be helpful.

You can sleep normally, even on Sunday nights.

How Long Should You Wait Between Screen Light Exposure and Going to Bed?

By Brandon Peters, MD

There is some concern that light exposure at night may affect sleep. What is the evidence that artificial light from screens contributes to insomnia? How long should you wait between screen light exposure and going to bed? Explore this relationship and some of the science behind the rationale.

The Science of Sleep

When considering how optimal sleep occurs, it is important to understand the two primary contributors: homeostatic sleep drive and circadian rhythm. Sleep drive is the fact that the longer you stay awake, the sleepier you will become. This is due to a chemical that gradually builds in the brain with prolonged wakefulness. This chemical is called adenosine. High levels of adenosine contribute to the onset of sleep. Sleep, at least in part, is a process of clearing this chemical away until consciousness is restored. Interestingly, caffeine blocks this signal and alcohol enhances it.

The circadian rhythm is the complement to this system. It is predominately an alerting signal that strengthens during the daytime and is largely absent overnight. It becomes strongest in the late evening hours, when we would expect to feel fairly sleepy. There is a lull in the mid-afternoon, which can contribute to a desire to take a nap then.  The circadian rhythm is based in our genetics, persisting without external influences. It contributes to sleep-wake propensity, hormone release, and metabolism. These processes are linked to the day-night cycle of light and darkness via the eyes.

How Light Changes Sleep

A simple anatomy lesson reveals the importance of light exposure to sleep. The eyes perceive light via the retina and pass this information along the optic nerves, extensions of the brain itself. These optic nerves receive input from each eye and cross at a location called the optic chiasm. Just above this is an area of the brain called the hypothalamus, a functional area that is integral to the control of the processes described above.

Within the hypothalamus lies the suprachiasmatic nucleus. This is the control center of the body’s circadian rhythm. It is the central pacemaker, coordinating the activities of all the body’s organs, tissues, and cells. Therefore, light input can be directly linked to the influence of many of the body’s processes.

In particular, light exposure can suppress the desire for sleep. Morning sunlight exposure may help to wake us, initiating the circadian alerting signal. In the same way, artificial light at night may affect the timing of sleep. It may contribute to insomnia in susceptible individuals, especially among those with a tendency towards being a night owl (called delayed sleep phase syndrome).

Preserving Darkness in the Night

What impact did Thomas Edison have on sleep in inventing the light bulb? As society has evolved, the potential disturbances have only expanded. With electricity, our evenings are filled with activity: televisions, computers, tablets, e-books, and phones that flicker light into our eyes. Moreover, the activity itself may keep us awake, shorten our total sleep time, and interfere with a relaxing buffer zone before bedtime. There is some evidence that light at night may adversely affect sleep.

Research has demonstrated that in the spectrum that we perceive as light, the blue wavelength is the one that can change our circadian rhythms. Therefore, industries have developed to supply filters and glasses that block the blue light. It seems that even short bursts of light, especially when of higher intensity, can impact sleep’s timing.

The sun is much more powerful in intensity compared to light from bulbs or screens. Full sunlight may be 100,000 lux in intensity while overhead lights may be just 1,000 lux. Therefore, a blast of sunlight at night could profoundly impact sleep. For susceptible individuals, artificial light may also negatively impact sleep onset and contribute to insomnia.

As a result, it is recommended that people who have difficult falling asleep may benefit from reduced light exposure prior to bedtime. Preserve the last 1 hour, and perhaps longer in highly sensitive individuals, as an electronics-free zone. Power off your screens, especially those that are closer to your eyes. It is also advisable to keep your bedroom free of electronics to preserve sleep. This is especially important advice for teens and children.

Why might some people not be bothered by light at night? The complement system, characterized by sleep drive and building levels of adenosine, could counteract these effects. If you are sleepy enough, you may not be bothered by the light. If you struggle with persisting insomnia, consider speaking with a sleep specialist to help determine ways for you to improve your sleep.

How Long Should You Wait Between Exercising and Going to Bed?

By Brandon Peters, MD

If you exercise late and have trouble falling or staying asleep, symptoms that characterize insomnia, you might wonder: How long should I wait between exercising and going to bed? Learn how much time should elapse after your exercise before bedtime and what symptoms you might experience if you don’t wait long enough before going to sleep.

The Relationship Between Exercise and Sleep

There are some theoretical impacts of exercise on sleep that you might take into consideration. Vigorous, aerobic exercise may increase your body temperature. An elevated body temperature may make it harder to fall asleep, as most of us prefer to sleep in a slightly cool environment. Fortunately, your body temperature is well regulated by sweating and once you are no longer sweating, it is likely mostly normalized.

In addition, exercise can release hormones such as cortisol and adrenaline (also called epinephrine). These hormones may rev you up, making it slightly harder to fall asleep. The good news is that they are likely not too disruptive and may actually enhance your sleep. In fact, when you are more active during the day, most people report sleeping better at night.

How Long to Wait Between Exercise and Bedtime?

In the past, sleep experts recommended avoiding exercise for 4 hours before going to sleep. Recently, this recommendation has changed. For many people who work, no exercise in the 4 hours before bedtime led too often to simply no exercise. Given the health implications, this is no longer suggested.

Instead, it is recommended that you stay active and exercise every day. It is not necessary to avoid exercising before bedtime. If you find that you are having difficulty getting to sleep on the nights you exercise right before bedtime, you might consider changing the timing of your exercise or your activity. In general, low-impact stretching and walking are great ways to unwind and may be done in the last few hours of the night without negative impacts on sleep.

If you continue to have difficult falling or staying asleep, speak with a sleep specialist about ways to help you to sleep better.

Sleep and the Back-to-School Middle Schooler: What They Need and Why

The middle school years bring a whirlwind of change — new friends, tougher classes, bigger responsibilities, and a growing sense of independence. But one thing often gets overlooked during this transition: sleep. For 11- to 14-year-olds, getting enough high-quality rest isn’t just a nice idea — it’s essential for learning, mood regulation, and healthy development.

As summer fades and the school year begins, schedules shift earlier, homework piles up, and extracurricular activities kick in. Without careful planning, sleep can become the first casualty of the busy school routine. Understanding what middle schoolers need and how to help them get it can make the difference between a year of thriving and one of dragging.

How Much Sleep Do Middle Schoolers Need?

The American Academy of Sleep Medicine recommends 9–12 hours of sleep per night for children aged 6–12, and 8–10 hours for teens 13–18. That means most middle schoolers should be getting somewhere between 9 and 10 hours nightly.

But research shows many don’t. A CDC survey found that fewer than half of middle school students regularly get enough sleep on school nights. Late bedtimes, early alarms, and the lure of screens all contribute to the problem.

Why Sleep Is So Important in Middle School

Sleep affects middle schoolers in ways that are both immediate and long-term:

• Cognitive performance: Sleep helps consolidate memories, process new information, and support creative problem-solving. Well-rested students pay better attention in class and remember more of what they learn.

• Emotional regulation: Hormonal changes in early adolescence can amplify emotions. Adequate sleep makes it easier to handle stress, avoid conflicts, and recover from disappointments.

• Physical health: Sleep strengthens the immune system, supports growth, and helps regulate appetite and metabolism.

• Safety: Sleep-deprived students are more likely to make impulsive choices and have slower reaction times, which can be risky during sports, biking, or crossing streets.

The Middle School Sleep Challenge

Several factors make it harder for middle schoolers to get the rest they need:

1. Shift in circadian rhythm
   As children enter puberty, their natural “sleep phase” shifts later. Melatonin — the hormone that signals bedtime — is released later at night, making it harder to feel sleepy early.

2. Earlier school start times
   Many middle schools start before 8:00 a.m., which can require a wake-up time around 6:30 or earlier — out of sync with a teen’s biological clock.

3. Increased homework and activities
   Sports, music, clubs, and other commitments can push dinner, homework, and bedtime later.

4. Screen time
   Phones, tablets, and gaming consoles not only tempt kids to stay up later but also emit blue light that delays melatonin release even more.

Preparing for the Back-to-School Sleep Shift

If your middle schooler has been staying up and sleeping in during the summer, shifting back to a school schedule in one night will be a shock to the system. Start adjusting 1–2 weeks before school starts:

• Move bedtime earlier by 15 minutes every few nights.

• Wake them earlier in the morning to match the school-day schedule.

• Keep the schedule consistent on weekends to reinforce the body clock.

Building a Sleep-Friendly Evening Routine

A consistent wind-down routine can help counteract late-night energy and screen distractions. Consider a 30–45 minute bedtime ritual that might include:

1. Wrapping up homework and organizing the backpack for the next day.

2. Turning off all electronics at least 30–60 minutes before bed.

3. Taking a warm shower or bath.

4. Reading a book or listening to calming music.

Parents can help by setting a clear “screens off” time and charging devices outside the bedroom.

Creating the Right Sleep Environment

Middle schoolers may not think their bedroom setup affects their sleep — but it does. Encourage:

• Darkness: Blackout curtains or a sleep mask can help.

• Cool temperature: Around 65–70°F (18–21°C) is ideal.

• Quiet: White noise machines can mask household sounds.

• Comfortable bedding: A supportive pillow and breathable sheets make a difference.

Balancing Activities and Rest

Middle schoolers often want to “do it all,” but overscheduling can push sleep to the bottom of the priority list. Help your child balance commitments by:

• Limiting late-evening practices or events on school nights.

• Encouraging them to choose a manageable number of extracurriculars.

• Scheduling downtime after school before jumping into homework.

Watching for Signs of Sleep Deprivation

Even a shortfall of 30–60 minutes per night can add up over a week. Look for:

• Difficulty waking up in the morning

• Irritability or mood swings

• Trouble concentrating

• Frequent yawning or daydreaming

• Dozing off in the car or on the couch after school

If you see these signs, reevaluate bedtime and daily schedule.

Setting a Good Example

Kids this age notice when adults burn the candle at both ends. Modeling good sleep habits — such as sticking to a regular bedtime and limiting screens late at night — reinforces the message that rest matters.

The Takeaway for Families

Middle school is a period of rapid growth and increasing demands. Without enough high-quality sleep, students risk falling behind academically, feeling overwhelmed emotionally, and struggling physically. But with consistent schedules, mindful routines, and supportive boundaries, parents can help ensure their child gets the rest they need to thrive.

As the school year begins, remember: academic success starts the night before — with lights out, a quiet room, and the steady breathing of a child who’s truly recharging for the day ahead.

Helping a New Kindergartener Adjust Their Sleep Routine

Starting kindergarten is a big milestone — not just for the child, but for the whole family. The excitement, new schedule, and increased demands on attention and energy all mean one thing: sleep becomes more important than ever. Unfortunately, getting a young child to bed on time (and helping them stay rested) can be a challenge, especially if they’ve been on a looser summer schedule.

The good news is that with some planning and consistency, you can help your kindergartener adjust to their new sleep routine without too many tears — yours or theirs.

Why Sleep Matters More Than Ever

Five- and six-year-olds need 10–13 hours of sleep in every 24-hour period, according to the American Academy of Sleep Medicine. That means if your child needs to wake up at 7:00 a.m. for school, their bedtime should ideally be somewhere between 6:30 and 8:00 p.m.

Adequate sleep at this age is linked to:

• Better mood regulation (fewer meltdowns)

• Improved attention and memory

• Stronger immune function

• Better coordination and motor skills

• More resilience in handling new challenges

The first weeks of kindergarten can be especially tiring. Your child is learning routines, meeting new people, and processing a huge amount of new information. Sleep is when their brains and bodies recharge — and without enough of it, their ability to adjust and thrive can suffer.

Step 1: Start the Adjustment Early

If your child has been going to bed later during the summer, don’t wait until the night before school starts to make changes. Begin adjusting bedtime and wake-up time about 2–3 weeks before the first day of kindergarten.

Move bedtime earlier by 10–15 minutes every few nights, and wake them up earlier in the morning by the same increment. Gradually shifting helps their body clock adjust without a huge shock.

Step 2: Create a Predictable Bedtime Routine

Young children thrive on structure, and a predictable bedtime routine signals to their body and brain that it’s time to wind down. Aim for a 30–45 minute routine that might look like this:

1. Bath or shower — warm water helps lower body temperature afterward, which can promote sleepiness.

2. Pajamas and tooth brushing — keep it consistent every night.

3. Quiet time — reading a book together or listening to calm music.

4. Lights out — ideally in a dim, quiet room.

Avoid high-energy activities and bright lights in the hour before bedtime. That means no roughhousing, TV shows, or tablets right before sleep. The blue light from screens can delay melatonin production, making it harder for kids to fall asleep.

Step 3: Make the Bedroom Sleep-Friendly

Kindergarteners, like adults, sleep better in an environment that’s comfortable and free from distractions.

• Keep it cool: A room temperature between 65–70°F (18–21°C) is ideal.

• Dim the lights: Darkness signals the brain to release melatonin. A small nightlight is fine if your child prefers it.

• Limit noise: White noise machines can help block out household or street sounds.

• Choose comfortable bedding: Involve your child in picking sheets or a blanket they love — it makes bedtime more inviting.

Step 4: Watch the Afternoon Schedule

Once school starts, you may notice your child is more tired than usual in the afternoons. Some kindergarteners still need a short nap, especially during the early weeks. However, a late afternoon nap can push bedtime later, so try to limit naps to before 3:00 p.m.

If they’re not napping, build in quiet time after school — reading, drawing, or playing calmly in their room — to give them a mental and physical break before the rest of the day.

Step 5: Be Consistent on Weekends

It’s tempting to let bedtime slide on Friday or Saturday nights, but big swings in schedule can make Monday mornings much harder. Try to keep bedtime and wake-up time within an hour of the weekday schedule, even on weekends.

Step 6: Handle Bedtime Resistance Gently but Firmly

Some kids may resist the earlier bedtime, especially if they’re used to staying up later. Stay calm, stay consistent, and remember that part of your job is to set boundaries that protect their health.

• Acknowledge feelings: “I know you don’t feel tired yet, but your body needs rest so you can have fun at school tomorrow.”

• Offer choices within structure: “Do you want to read one book or two before lights out?”

• Stick to the routine: Consistency builds habits faster than constant negotiation.

Step 7: Watch for Signs of Sleep Deprivation

Even with a good plan, some children may struggle to get enough sleep at first. Watch for signs such as:

• Morning irritability or crying

• Difficulty waking up

• Meltdowns over small frustrations

• Clumsiness or more frequent accidents

• Trouble focusing during play or homework

If you notice these signs regularly, try moving bedtime even earlier. It’s not unusual for some kindergarteners to need a 7:00 p.m. bedtime, especially in the first few months of school.

Step 8: Stay Flexible and Supportive

Every child is different. Some adjust within a week, while others may take a month or more to settle into a new sleep pattern. Life events, growth spurts, and illness can all cause temporary setbacks.

The key is to treat sleep as a non-negotiable priority, while also giving your child space to adapt at their own pace. Celebrate small wins — like falling asleep without calling for you — and keep reinforcing the idea that sleep helps them be their best.

The Long-Term Payoff

Helping your kindergartener adjust to a healthy sleep routine is one of the best back-to-school gifts you can give them. Not only will it make their days happier and more productive, but it will also lay the foundation for lifelong sleep habits that support health, learning, and emotional well-being.

A well-rested child is better equipped to meet the exciting challenges of school — from making new friends to learning to read — with energy and joy. And as a parent, you’ll have more peace of mind knowing you’ve set them up for success, one bedtime story at a time.
