ADHD and Sleep Issues

For many families with kids who have ADHD, sleep is one of the biggest challenges faced by both parents and kids. Bedtime can be chaotic. Kids may take hours to fall asleep. Some wake up repeatedly during the night, while others can’t wake up in the morning. And in many households, both parents and kids end up exhausted before the day even begins.

These ADHD sleep issues are very common. William Benson, PhD, a psychologist in the ADHD and Behavior Disorders Center at the Child Mind Institute, says sleep problems are “one of the most frequent challenges” he sees in children and teens with ADHD. “Some estimates suggest that 50 percent or more of individuals with ADHD experience significant sleep disturbances,” he says. And for some kids, sleep problems can be a side effect of taking stimulant medication for ADHD.

Understanding why sleep is so difficult for these kids — and how families can support healthier sleep — can bring some relief to what often feels like a nightly battle.

Some kids with ADHD have trouble at the start of the night, some in the middle, and some at the end. Many have difficulty in all three. Here are some of the patterns Dr. Benson sees most often:

Kids stall, resist bedtime routines, or insist they’re “not tired.” Teens may suddenly seem energized or hyper-focused on something just as they should be getting ready for bed.

Even when they’re tucked in, kids may feel restless or uncomfortable, or their minds may be racing. Many describe feeling “wide awake” even when they’re exhausted.

Some children fall asleep but can’t stay asleep, waking up multiple times a night. Others wake very early — sometimes before dawn — and can’t fall back asleep.

Even when they appear to be asleep for a full night, their sleep may be lighter or more fragmented. According to Dr. Benson, sleep studies have shown that kids with ADHD often cycle differently through sleep stages.

For many families, mornings are the most stressful part of the day. Kids and teens with ADHD may sleep deeply and be extremely hard to rouse, and transitions from sleep to wakefulness can be fraught.

Barbara O’Dair, an ADHD coach and author of the Substack You’ve Got My Attention, remembers vividly the difficulty of waking her younger daughter in the morning. “One morning I was so desperate, I threw water on her to get her to wake up,” says O’Dair, who was also diagnosed with ADHD in her forties. “I only did it once and I regretted it immediately. But I was at my wit’s end.”

Kids with ADHD have sleep issues, even when they’re tired, because they find it difficult to quiet their emotions and racing thoughts at night. “Being able to wind down, calm your thoughts, and settle your body is a form of self-regulation,” Dr. Benson explains. “And that’s something kids with ADHD struggle with.”

Kids with ADHD may have also have trouble:

• Stopping an activity they’re enjoying to go to bed
• Putting aside stimulating things (like devices)
• Noticing internal cues that they’re getting tired
• Following multi-step bedtime routines without getting distracted

For many people with ADHD, these challenges show up early and persist into adulthood.

“I was a night owl ever since I can remember,” says O’Dair. “Whenever I had the chance to stay up, I would. That was my natural tendency.” Nighttime, she says, was when she felt most alive. “I felt very creative late at night. My energy turned on then. I’d get so much done.”

One of her favorite night habits as a preteen was rearranging her bedroom furniture. She’d drag heavy pieces across the floor in the middle of the night, creating new “nooks” while the rest of her family slept. She also spent many late hours watching old movies. “I learned a lot about old movies because I was the only one awake at two in the morning,” she says. “It was kind of a lonely pursuit.”

That tendency toward late-night wakefulness — often fueled by bursts of creativity or focus — is extremely common for people with ADHD. But ADHD itself isn’t the only factor that contributes to sleep difficulties. Dr. Benson points to several related or overlapping issues:

• Anxiety: Kids with ADHD often struggle with anxiety, which tends to intensify at night. Bedtime can be when worries surface.
• Inconsistent routines: Because transitions are hard, kids with ADHD thrive on predictability — but establishing predictable sleep routines can be challenging for families who are stretched thin.
• Natural circadian shifts in adolescence: Teenagers naturally fall asleep later because of changes in their internal clocks. For teens with ADHD, this shift can be even more pronounced.
• Stimulant medication: In some children, stimulant medication for ADHD causes, or worsens, sleep issues. Ideally the medication is out of their system by bedtime, but if it’s still active it can keep them awake.

The relationship between ADHD and sleep runs both ways. Kids with ADHD have a harder time sleeping — and when they don’t get enough sleep, their ADHD symptoms get much worse. But also, “when kids don’t get enough sleep, the symptoms can look almost identical to ADHD,” Dr. Benson explains. This can lead to misdiagnosis in kids who have sleep problems but don’t have ADHD.

Poor sleep can result in difficulty concentrating, irritability, impulsivity, forgetfulness, and disorganization. Kids who are tired may have more emotional ups and downs, more trouble switching between tasks, and less patience for frustration. Morning routines become harder, and schoolwork requires even more effort. Teachers may report that the child is more distractible than usual, or that they’re struggling with transitions.

Good sleep won’t eliminate ADHD, but improving sleep can make symptoms more manageable and help kids feel more regulated during the day.

Behavioral tools and routines are often the most effective long-term solutions for sleep problems in kids with ADHD. Dr. Benson emphasizes that these strategies are powerful when used consistently, even if results take time. Some of the most effective supports include:

• A predictable bedtime routine: Kids with ADHD do best with routines that start at the same time every night and follow the same steps in the same order. Routines help signal to the brain that it’s time to wind down.
• Limiting screens in the evening: The blue light from screens can interfere with the brain’s natural “sleepiness” hormones and keep kids wired at bedtime.
• Exercise earlier in the day: Physical activity helps with sleep, but vigorous exercise right before bed can have the opposite effect.
• Avoiding late-night snacks, chocolate, and caffeine: Kids with ADHD are often sensitive to stimulation late in the day.
• CBT-I (Cognitive Behavioral Therapy for Insomnia): This structured behavioral treatment helps kids manage the thoughts and habits that interfere with sleep. It’s considered the gold standard for insomnia in teens and adults, and many of its strategies can be adapted for younger kids.
• Relaxation and mindfulness techniques: Breathing exercises, guided imagery, or progressive muscle relaxation can help kids quiet both their bodies and their minds.

“Think of these strategies like training the brain,” Dr. Benson says. “You’re teaching the body what to expect and helping the sleep system become more predictable.”

Sleep problems are common side effects of stimulant medications, which can interfere with sleep if they are still in a child’s system at bedtime. Adjusting the timing or type of the medication can help. If a child is taking a short-acting formula, it may mean that they are taking a second or third dose too late in the day. If they are taking medication that lasts 12 or 14 hours, it may help to try one that’s not quite as long acting.

Sleep issues caused by the medication tend to get better over time, so it’s worth trying it for four to six weeks to see if the child adjusts to what they’re taking. If the problem isn’t resolved, switching to a different stimulant, or an non-stimulant medication, can help.  

For some kids with ADHD, Dr. Benson adds, “being medicated actually helps them sleep because their nervous system is more regulated.”

Some medication options include:

• Guanfacine (Tenex)
  This nonstimulant ADHD medication can cause drowsiness, which may help some children fall asleep more easily.
• Delayed-onset stimulants like Jornay PM
  These are taken at night but don’t take effect until morning, which can help kids who have trouble waking up and getting going for school.
• Melatonin
  Melatonin tends to help with falling asleep, but it won’t solve night wakings. Medication isn’t the first-line solution for sleep, Dr. Benson emphasizes, but it can be part of a larger strategy.

While common, melatonin is still a medication and should be used under a doctor’s guidance. Over-the-counter medications are not subject to the same testing and standards as prescription ones, so different brands vary widely in how much melatonin they actually contain.

Dr. Benson encourages parents to remember that most kids with ADHD are not choosing to be difficult around sleep. “Kids aren’t trying to give their parents a hard time,” he says. “They’re having a hard time.”

O’Dair agrees — and says it’s important for parents to extend that compassion to themselves as well. “It’s tough,” she says. “But it’s not their fault. And beating yourself up for not being able to fix it doesn’t help anyone.”

What does help is approaching sleep with patience and realistic expectations. Progress is rarely linear. Some nights will go smoothly; others will be frustrating. Keeping routines predictable, offering support instead of pressure, and celebrating small wins can go a long way. Even small improvements can make mornings calmer, school days easier, and family life more manageable.
