Sunlight and ADHD

RESEARCHERS are interested in exploring how sunlight, sleep and screens (like those on computers and TVs) may affect those with attention-deficit/hyperactivity disorder (ADHD), says Dr L. Eugene Arnold, a child psychiatrist and ADHD expert at the Ohio State University Wexner Medical Center’s Nisonger Center, US.

ADHD is a neurodevelopmental disorder characterised by developmentally inappropriate degrees of inattentiveness, impulsivity and hyperactivity. Although ADHD is the most common neuropsychiatric/behavioural disorder of childhood and has been extensively studied in young children, it occurs in all age groups.
