It’s clear that being around nature is good for one’s health, but why? Researchers have been looking into the physiological reasons for the benefits of nature and multiple reasons have been found. Being in nature is good for you in many tiny ways that culminate into a big benefit to your immune system. Everything from a small house plants to large trees in local parks helps your immune system function better.
Be comforted knowing that you can improve your health (and other’s) by just helping plants grow.
In built environments, trees and landscaping may promote health not only by contributing positive factors like phytoncides but also by reducing negative factors. Air pollution is associated with myocardial inflammation and respiratory conditions (Villarreal-Calderon et al., 2012). High temperatures can cause heat exhaustion, heat-related aggression and violence, and respiratory distress due to heat-related smog formation (Anderson, 2001; Akbari, 2002; Tawatsupa et al., 2012). And violence affects physical and mental health (e.g., Groves et al., 1993). Vegetation filters pollutants from the air (although see Table 2 in the Supplementary Materials for details), dampens the urban heat island (e.g., Souch and Souch, 1993), and appears to reduce violence (Table 2 in the Supplementary Materials for review).
