The study identified a genetic overlap between ADHD and reduced melatonin, a hormone that signals the body to wind down before bedtime. As many as half of all kids diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) struggle to sleep. ADHD is a neurodevelopmental condition that impacts the ability to focus, sit still, and practice impulse control. While scientists have suspected that an out-of-sync circadian rhythm might play a role, the precise biological connection between ADHD and sleep has been unclear. The brain produces its peak melatonin levels in response to darkness after nightfall. While melatonin doesn’t directly cause drowsiness, it plays a key role in signaling the body to wind down before bed. To check for a potential genetic link between melatonin secretion and ADHD, the researchers compared the data from two large studies: one focusing on the genetic basis of ADHD and the other on melatonin production. While melatonin supplementation could be a promising intervention, more studies are needed to understand its long-term effects. In the meantime, parents and guardians can focus on supporting melatonin’s natural rhythms by encouraging routines that include adequate daylight exposure, minimized evening screen time, and dimmed lights before bedtime. For adults who are still managing ADHD, small, mindful lifestyle adjustments like these may also help in improving focus, sleep quality, and overall well-being.
