Nature indeed has remarkably healing abilities. Findings of a new study have found the removing trash and planting grasses and trees in vacant lots can make people happier and reduce symptoms of depression، as the Technical Times said. In a new study published in JAMA Network on Friday، July 20، researchers reported that converting empty lots into clean and green space can significantly reduce depression in residents within a quarter mile.
Study researcher Eugenia South، from University of Pennsylvania Hospital، and colleagues looked at 541 vacant lots around Philadelphia. Grasses and trees were planted in a third of these lots، and another third had the trash removed.
The researchers then tracked the emotional state of 342 locals from 2011 to 2014 during the period of the cleanup study. They found that the residents in areas where there were greening or trash removal projects experienced reduced feeling of depression by about 40 percent. Residents in neighborhoods below the poverty line reported reduced feeling of depression by 70 percent.
South and colleagues also found that those who lived near renovated lots had reduced feelings of hopelessness، worthlessness، and overall poor mental health. In people who lived in lots that were not cleaned، levels of depressions stayed the same or only changed slightly.
The residents themselves noticed the beneficial changes.
