Trees are good for everyone, but they appear to be especially beneficial for girls. A study by University of Illinois researchers Frances Kuo, Bill Sullivan, and Andrea Faber Taylor found that the greener and more natural a girl’s view from home, the better she scored on tests of self-discipline.

The greater a girl’s self-discipline, the more likely she is to do well in school, to avoid unhealthy or risky behaviors, and to behave in ways that foster life success. Self-discipline was measured by the ability to concentrate, to inhibit impulsive behavior and to delay gratification.

Boys showed no link between test scores and nature near home, but for girls, on average, the greener the view the higher the scores.
