Move More, Think Better: How Exercise Helps Kids with ADHD Sleep and Focus

Many children with ADHD find it tough to get a good night's sleep. They also often struggle with paying attention, holding information in mind, and switching between tasks. Scientists wondered if moving their bodies more could make a difference.

To test this idea, researchers put a small motion tracker on 282 kids aged six to twelve who have ADHD. The kids wore the tracker for seven days straight, letting the team measure how much they moved and how they slept. At the same time, the children filled out a sleep questionnaire and completed a set of game-like tasks that measure inhibitory control, working memory, and cognitive flexibility.

About sixty percent of the group reported sleep problems. Compared with peers who slept well, these children took longer to fall asleep, showed lower scores on the flexible-thinking task, spent fewer minutes each day in moderate-to-vigorous activity, and were less likely to reach the recommended sixty minutes of active play. The study found that how they rated their sleep, their sleep efficiency, daytime tiredness, and whether they met the activity guideline were all tied to their performance on the thinking tests. Moreover, the connection between feeling tired during the day and poorer flexible thinking disappeared when kids got enough exercise.

This suggests that daytime sleepiness only hurts flexible thinking for those who are not moving enough. It raises the question: could sticking to the daily activity recommendation help ease both sleep troubles and thinking challenges in kids with ADHD? More work is needed to find out.
