VitaminN, a Potential Natural Treatment for Children with ADHD

Children With Attention Deficits Concentrate Better After Walk in the Park

In a 2004 study, children with Attention-Deficit/Hyperactivity Disorder had fewer symptoms when activities were carried out in a green or natural outdoor setting such as parks, woods, farms, etc., than they did when in outdoor human-built settings or in indoor settings.

Nature, or what in recent years has been referred to as vitamin N, may be one of the answers as treatment for ADHD…


Could ADHD be, in part caused or at least exacerbated by, an imbalance between a highly-technologically focused, exceedingly structured fast-paced, urban lifestyle and a natural, non-structured, green, outdoor environment?

We examined the impact of relatively “green” or natural settings on attention-deficit/hyperactivity disorder (ADHD) symptoms across diverse subpopulations of children.

Parents nationwide rated the aftereffects of 49 common after-school and weekend activities on children’s symptoms. Aftereffects were compared for activities conducted in green outdoor settings versus those conducted in both built outdoor and indoor settings.

In this national, nonprobability sample, green outdoor activities reduced symptoms significantly more than did activities conducted in other settings, even when activities were matched across settings. Findings were consistent across age, gender, and income groups; community types; geographic regions; and diagnoses.

Green outdoor settings appear to reduce ADHD symptoms in children across a wide range of individual, residential, and case characteristics.
