The researchers calculated the amount of symptom improvement in the study and compared it to symptom improvement in a recent medication study and  were surprised to see that the dose of nature had the same effects- or even better - than the dose of medication.

"What remains to be seen is how long the effects of a dose of nature last," said Faber Taylor.

Though this specific study only followed 17 children, the researchers noted that a much larger study, of over 450 children showed similar findings.

According to Taylor, the evidence from both studies suggests that getting outdoors, in a natural green setting, can benefit everyone, even children (and adults) who have not been diagnosed with ADHD.  Additionally, there is no cost involved, no side effects and it is fairly easy to access such areas. 

So perhaps we should all take our mothers' advice and get outdoors every day for a dose of nature!
