Loneliness has become a global public health concern. Countries including Britain and Japan have appointed "ministers of loneliness" to help tackle the problem. In the United States, then-Surgeon General Vivek H. Murthy issued a public health advisory on loneliness, stating that the risk for premature death from loneliness is akin to smoking up to 15 cigarettes a day. What if, instead of trying to "fix" the individual, strategies focused on shaping the environment in a way that facilitates social connection? Recently, researchers have been trying to leverage nature as a way to bring people together and reduce negative feelings about social isolation. They say living in what is known as a "lonelygenic environment" " one dominated by cars and concrete instead of grass and trees " can cause or aggravate loneliness. Even if you live in a lonelygenic environment, experts say, spending just an hour or two in nature per week ... may help people feel less isolated. One proposed approach for tackling loneliness as a public health issue is through social prescribing, where physicians connect their patients with non-medical services in the community similar to how they prescribe medication. Nature comes in many forms. An ongoing study by [Matthew] Browning and his colleagues investigates the amount of time a representative sample of Americans spends outdoors in nature. "What we find is that nature is, for most people ... watching their kids play soccer outside or grilling in the backyard."
