Decades of research shows that being socially connected helps us live longer, healthier, and happier lives. But it isn’t just our family ties, close friendships, or group membership that make a difference. Evidence reveals that the health benefits of social connectedness can be unlocked starting at home, with our own neighbours.
Social connectedness is vital to our health and well-being. Substantial evidence shows that people who are socially connected live longer.(1,2) A lack of social connection — marked by social isolation and loneliness — increases risk for premature death by as much as 50%, comparable to major health risks like obesity, smoking, and air pollution.(2,3) The effect of social connectedness on life expectancy is independent of other risk factors like age, sex, initial health status, lifestyle factors, income, and education. In addition to premature mortality, poor social connectedness has been linked to a range of other adverse physical, cognitive, and mental health outcomes, including increased risk of heart disease and stroke, respiratory infection, dementia, depression and anxiety.(2)
The influence that social connectedness has on our health and well-being can be biological, psychological, or behavioural. For example, social connectedness influences immune functioning and inflammation, which has been linked to several chronic diseases. Supportive social connections also help us cope with stress, and influence healthy behaviours like sleep and physical activity.(2)
Given mounting evidence on its health effects, local and global declines in social connectedness are increasingly recognized as a public health crisis that requires policy action at all levels. New data shows that more than 1 in 10 British Columbians reported feeling lonely always or often.(4) For young adults or those living alone, the proportion of people experiencing loneliness doubles to more than 1 in 4.(5) In the wake of the COVID-19 pandemic, the United States Surgeon General has described social connectedness as equally important to global recovery as vaccines. Evidence shows that one way to curb social isolation and loneliness is to start at home, by building connections and community among neighbours.
What we know
People who live in socially connected neighbourhoods report better physical health, mental health, and well-being.
Connections between neighbours can be beneficial to health and well-being at all stages of life.
Neighbours are an important source of tangible and emotional support — key ingredients for health and well-being.
