People who spend more time in parks and other natural settings tend to report higher levels of health and happiness, but new research shows there’s actually a magic number for it.
Those who got in two to three hours in nature were about 20 percent more likely to report high overall satisfaction with their lives than those who spent no time outdoors at all. The benefits to physical health were even greater, with those who met the outdoors benchmark being 60 percent more likely to report being in good health than their cooped-in counterparts.
There’s already a substantial body of work linking green spaces to lower risks of heart disease, diabetes, obesity, asthma, mental health problems and overall mortality; and to greater rates of health, happiness, and cognitive development in children.
But most of these studies simply measured the physical characteristics of neighborhood environments. Overall, they found, two hours or more of nature exposure had a significant impact: Its positive effect on an individual’s health and well-being was comparable to getting recommended amounts of exercise or of living in a high socioeconomic status area versus a low-status one.
They stress, however, that the effect is not necessarily a causal one. Though researchers controlled for a wide range of variables known to affect health and happiness, the study’s design didn’t allow them to completely rule out other factors that could result in higher health and happiness for nature lovers.
It may be the case, for instance, that people who are more inclined to be physically active and have a positive outlook on life are more likely to seek recreation opportunities outdoors. It may also be the case that being outside in nature, which typically involves a lot of moving around, may serve as a proxy for physical activity overall.
