Living Near Trees Means Fewer Antidepressants
Trees are incredibly intelligent. They run in the sun, shade in summer and ever so gently drop their leaves to allow the sun through winter. And now a team from the University of Exeter has determined that are good for our mental health, too. Londoners who had more trees on their streets were fewer antidepressant pills. Citylab Eric Jaffe reports:
The study methods were clear: The researchers collected data on antidepressant prescriptions through London in 2009-2010 and matched with data on street trees in the same area. ... The numbers reveal an average of 40 trees per kilometer through the districts of London with antidepressant prescriptions ranging from 358 to 578 per 1,000 people. But places with high densities of trees had lower prescription rates.
So what is it about trees that make us happier? Perhaps they know that they will live longer, as was discovered by Geoffrey Donovan looked at comparable mortality rate s in areas where the emerald ash borer-killed all the trees. Another study found that Donovan trees prevent crime , the correlation of coverage tree with crime statistics; the trees, the lower the crime rate.
living near trees makes healthier
research by the Forest Service Department of Agriculture also showed that people living around trees are physically healthier: "about 850 lives are saved each year, the number of symptoms acute respiratory is lower by about 670,000 incidents each year, and the total savings for the health care attributed to the elimination of pollution by trees is about $ 7 billion a year. "
More in per square mile , Tim Chant spent some quality time with Google Earth, comparison neighborhoods and find that (surprise!) rich neighborhoods have more trees. He also cites research on the subject:
They found that for every 1 percent increase in per capita income, demand for forest cover increased by 1.76 percent. But when income was reduced by the same amount, demand decreased by 1.26 percent. That's a fairly tight correlation. The researchers argue that wealthier cities can afford more trees, both private and public property. The well-to-do can afford larger lots, which in turn can support more trees.In fact, stacks of research show that people living around the trees are richer, healthier, safer, live longer and generally lead happier lives. In the United States, where the poor have easy access to medical care and prescriptions, you can twist the pill poppers on the economic ladder. Since the National Health System in the UK is given virtually everyone equal access to care and prescriptions should be no surprise that the poorest, the sickest and less happy would be taking more antidepressants.
The study authors state that have been adjusted for socioeconomic status, employment status, the prevalence of smoking and age. There is so much noise statistic here that it is impossible to say which factor is actually causing the difference, but the conclusion is clear: ". Trees in the streets can have a role to play in supporting neighborhood mental health"
Amen to that .
