ADHD and sleep - why it is hard to fall asleep and how to improve nighttime recovery20 czerwca 2026 |
People with ADHD very often find it difficult to fall asleep at a typical bedtime, even when they are already physically tired. Their nervous system may remain in a state of arousal long after the day has ended. That is why evenings often bring racing thoughts, the need to move, phone scrolling, bedtime procrastination or a sudden shift into hyperfocus. People with ADHD also commonly experience waking during the night, light sleep, tossing and turning in bed and difficulty getting up in the morning. In practice, people with ADHD often adopt very changeable sleeping positions: they sleep on their side, on their stomach, in the fetal position, with one leg pulled up high, with their hands under the pillow or in the commonly described "dinosaur position", meaning half on the side, half on the stomach, with the limbs arranged asymmetrically. This is often not accidental. It can be a search for pressure, stability and sensory "grounding" that helps the nervous system calm down.
Insufficient sleep or poor-quality sleep can intensify symptoms that are already characteristic of ADHD. After a bad night’s sleep, it is harder to maintain attention, control impulses, regulate emotions and start tasks that require cognitive effort. Irritability, fatigue, organizational chaos, lower motivation and greater sensitivity to overstimulation become more likely. In the long term, sleep problems can worsen functioning at work, in education and in relationships. A person with ADHD may then feel that they "cannot cope", although the real problem is not lack of willingness, but a nervous system operating under chronic sleep debt. That is why sleep is not an optional addition to therapy or daily organization, but one of the foundations of better functioning.
Sleep problems in ADHD can result from several overlapping mechanisms. One of them is a delayed circadian rhythm, which means sleepiness appears later than it does in most people. Another is difficulty slowing down brain activity, meaning the shift from doing, analyzing and reacting into rest mode. The need for stimulation also matters. In the evening, when the pressure of responsibilities disappears, the brain may seek a quick reward: a phone, a TV series, a game, conversations, online shopping or another idea that will take "just five minutes". In some people, sensory sensitivity also plays a role. They may be irritated by excessive temperature, uneven support, a poorly chosen pillow, the pressure of a seam, noise, light or an uncomfortable mattress. Sleep with ADHD therefore requires not only willpower, but also a well-designed sleep environment.
With ADHD, the best routine is one that does not fight the nervous system, but helps it gradually slow down. It is worth setting a wake-up time that is as consistent as possible, limiting intense stimulation in the evening, dimming the lights, keeping the phone out of reach and building a repeatable bedtime ritual. Calm sounds, brown noise, a warm shower, simple breathing exercises, light activity during the day and a predictable sequence of actions before sleep may help. The sleep environment is also very important. The bedroom should be dark, quiet, well ventilated and as free from stimuli as possible. The mattress should support the body steadily, while the pillow should keep the neck and head in a natural position, even when a person with ADHD often changes sleeping position. If sleep difficulties remain severe or long-lasting despite changes, or if there is a suspicion of sleep apnea, restless legs syndrome or chronic insomnia, it is worth consulting a doctor or psychologist.
No. People with ADHD do not need less sleep than others, although they often sleep for a shorter time, fall asleep later or function in an irregular rhythm. The fact that someone with ADHD can operate at high speed for a while after a short night does not mean that their body does not really feel it. An adult usually needs around 7-9 hours of sleep, while children and teenagers need even more. With ADHD, not only the number of hours matters, but also the regularity, quality and predictability of sleep. Less sleep usually does not mean greater productivity, but a higher risk of impulsivity, distraction, irritability and nervous system overload the next day.
