Nighttime Activity / Nighttime Restlessness (ADHD)

"Nighttime activity" or "nighttime restlessness" refers to a child’s inability to fall into a peaceful sleep in the evening and at night. The child tosses and turns in bed for a long time, talks, gets back up, or falls asleep only to wake up in the middle of the night and be wide awake. This occurs significantly more often in children with ADHD (attention-deficit/hyperactivity disorder) than in their peers.

Experts primarily distinguish between two patterns: trouble falling asleep (the child lies awake for a long time) and trouble staying asleep (the child wakes up at night and has difficulty falling back asleep). Difficulty falling asleep is the most common issue. Important for parents: This restlessness in the evening is not defiance or the result of poor parenting, but is closely related to the way the brain functions in ADHD.

According to estimates, nearly half of children with ADHD experience occasional sleep problems, and about one in ten children has them on a long-term basis. Overall, children with ADHD are two to three times more likely to have sleep disturbances than other children. Typical signs include:

• The child takes a very long time to wind down in the evening and often still seems hyperactive.
• They resist going to bed or are afraid of falling asleep alone.
• They wake up several times during the night or have a hard time getting out of bed in the morning.
• During the day, they seem overtired, irritable, or even more restless than usual.

Insufficient sleep can exacerbate ADHD symptoms. Inattention, impulsivity, and irritability then increase, and both family life and school can more quickly fall into a stressful cycle.

Sleep is controlled by an internal regulatory system that governs the transition between wakefulness and rest (sleep-wake regulation). In ADHD, this rhythm appears to be more prone to disruption. Research points to changes in the central nervous system and in neurotransmitter levels that play a role in both ADHD and sleep. The child may have trouble winding down in the evening because their mind and body are still geared toward activity.

Added to this is internal restlessness: Many children experience a constant stream of thoughts that won’t stop during the quiet evening hours. Without external distractions, this tension often becomes even more noticeable.

Treatment can also affect sleep. Stimulants such as methylphenidate have a stimulating effect and can make it difficult to fall asleep, especially when taken late in the day or when the dose is adjusted. Whether and to what extent this happens varies from child to child. Some children actually sleep more soundly with the right dosage because their inner restlessness subsides. Questions about dosage and timing of administration should always be addressed with the treating physician. If parents are unsure about this, an open discussion about their concerns regarding the medication can be helpful.

The first and most important step is sleep hygiene. This refers to consistent routines during the day, in the evening, and at night that help the body fall asleep. These routines can be adapted to the child’s age and situation. The following have proven effective:

• Consistent times: Go to bed and wake up at the same time every day, if possible, even on weekends.
• A calm evening routine: always follow the same sequence, such as washing up, reading aloud, and dimmed lights. Repetition signals to the brain that it’s time to wind down.
• Turn off screens early: Put away cell phones, tablets, and the TV at least one hour before bedtime.
• Activity during the day, calm in the evening: Avoid exciting games and sugar before bedtime.
• Minimize stimuli: A dark, cool, and quiet room helps reduce external distractions.

If these measures aren’t enough, behavioral therapy—under medical supervision—or, in certain cases, the sleep hormone melatonin can be considered. Such steps are part of a multimodal therapy that combines various components rather than focusing on just one area.

It’s a good idea to seek medical advice if sleep problems persist for weeks, if the child is severely affected during the day, or if the whole family is reaching its limits. Other noticeable symptoms include nighttime breathing pauses, loud snoring, or a pulling or twitching sensation in the legs. These symptoms may be caused by underlying sleep disorders that are treatable and sometimes trigger ADHD-like symptoms in the first place. That’s why it’s worth getting a thorough evaluation before attributing everything to ADHD.

The first point of contact is the pediatrician; if necessary, a referral to a child and adolescent psychiatry clinic will follow. As parents, you can provide a great deal of support and relief, but the assessment of symptoms, a diagnosis, and decisions regarding medication belong exclusively in the hands of a child and adolescent psychiatrist (KJP) or a medical or psychotherapeutic specialist.
