A study has found that children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) may benefit from "green time"- a brief exposure to green outdoor spaces.
Those who regularly play in outdoor settings with lots of green (grass and trees, for example) have milder ADHD symptoms than those who play indoors or in built outdoor environments, the researchers found.
In a study published in 2004, they analyzed data from a national Internet-based survey of parents of children formally diagnosed with ADHD and found that activities conducted in greener outdoor settings did correlate with milder symptoms immediately afterward, compared to activities in other settings.
"On the whole, the green settings were related to milder overall symptoms than either the 'built outdoors' or 'indoors' settings," Taylor said.
The researchers also found that children who were high in hyperactivity (diagnosed with ADHD rather than ADD) tended to have milder symptoms if they regularly played in a green and open environment (such as a soccer field or expansive lawn) rather than in a green space with lots of trees or an indoor or built outdoor setting.
The study has been published in the journal Applied Psychology: Health and Well-Being.
