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. The association holds even when the researchers controlled for income and other variables.
Although many children with ADHD are medicated, most “would benefit from a low-cost, side-effect-free way of managing their symptoms,” wrote University of Illinois crop sciences visiting teaching associate Andrea Faber Taylor and natural resources and environmental sciences professor Frances (Ming) Kuo, the authors of the study.
Previous research has shown that brief exposure to green outdoor spaces – and in one study, to photos of green settings – can improve concentration and impulse control in children and adults in the general population – individuals without ADHD.
These findings led Taylor and Kuo to examine whether children diagnosed with ADHD, which is characterized by deficits in concentration and impulse control, might also benefit from “green time.” 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.
The new study explores other data from the same survey to determine whether the effect also is true for green play settings that are routinely experienced – the park, playground or backyard that a child visits daily or several times a week.
“Before the current study, we were confident that acute exposures to nature – sort of one-time doses – have short-term impacts on ADHD symptoms,” Kuo said. “The question is, if you’re getting chronic exposure, but it’s the same old stuff because it’s in your backyard or it’s the playground at your school, then does that help?”
To address this question, the researchers examined parents’ descriptions of their child’s daily play setting and overall symptom severity. They also looked at the children’s age, sex, formal diagnosis (ADD or ADHD) and total household income.
The analyses revealed an association between routine play in green, outdoor settings and milder ADHD symptoms.“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 researchers found no significant differences between boys and girls or income groups in terms of the relationship between the greenness of play settings and overall symptom severity.
Kuo noted that the findings are correlational, and don’t by themselves prove that routine playtime in green space reduces symptom severity in children with ADHD. But in light of all the previous studies showing a cause-and-effect relationship between exposure to nature and improved concentration and impulse control, she said, “it is reasonably safe to guess that that’s true here as well.”
The study was performed with Hatch Act funds, and with support from the U.S. Department of Agriculture’s CSREES National Research Initiative with a recommendation from the National Urban and Community Forestry Advisory Council.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
