Greenery, Indoors and Outside, Implications (01-08-21)

Dzhambov and colleagues studied the effects of indoor and outdoor greenery on the wellbeing of people during the COVID pandemic.  They determined via a survey that “Greenery experienced both indoors and outdoors supported mental health. . . . We employed two self-reported measures of greenery experienced indoors (number of houseplants in the home and proportion of exterior greenery visible from inside the home) and two measures of greenery experienced outdoors (presence/absence of a domestic garden and availability of neighborhood greenery). . . . The relative abundance of greenery visible from the home or in the neighborhood was associated with reduced depressive/anxiety symptoms and lower depression/anxiety rates. Having more houseplants or a garden was also associated with some of these markers of mental health. . . . [Study participants] who spent most of their time at home during the COVID-19 epidemic experienced better mental health when exposed to more greenery. Our findings support the idea that exposure to greenery may be a valuable resource during social isolation in the home.”
