Children raised in greener areas have higher IQ, study finds

Research also found lower levels of difficult behaviour in rich and poor neighbourhoods

Growing up in a greener urban environment boosts children's intelligence and lowers levels of difficult behaviour, a study has found.

The analysis of more than 600 children aged 10-15 showed a 3% increase in the greenness of their neighbourhood raised their IQ score by an average of 2.6 points. The effect was seen in both richer and poorer areas.
