Living in greenery helps to get rid of many types of health problems. This increases life expectancy and also sharpens the mind. According to Spain’s IS Global Research Institute, the 3-30-300 green space rule should be followed for better mental health.
According to this rule, a person should see at least 3 trees from his house. The house should be in an area where the shade coverage of trees is 30%. Also, there should be a park or green space within 300 meters. Those who follow this rule have less mental health problems and also have to take less doctor’s medicine.
