A Solution For Loneliness: Get Out and Volunteer, Research Suggests

'Loneliness is rampant, and it's killing us,' writes Kasley Killam for Scientific American. 'Anywhere from one quarter to one half of Americans feel lonely a lot of the time, which puts them at risk for developing a range of physical and mental illnesses, including heart disease, cancer, diabetes, and depression.' Killam surfaces several studies that found volunteering to be an effective strategy to help combat this widespread health problem. From the report: In a recent survey of over 10,000 people in the UK, two-thirds reported that volunteering helped them feel less isolated. Similarly, a 2018 study of nearly 6,000 people across the US examined widows who, unsurprisingly, felt lonelier than married adults. After starting to volunteer for two or more hours per week, their average level of loneliness subsided to match that of married adults, even after controlling for demographics, baseline health, personality traits, and other social involvement. These benefits may be especially strong the older you are and the more often you volunteer.

Participating in volunteer opportunities may help alleviate loneliness and its related health impact for several reasons. The first and most obvious is that it's a meaningful way to connect with others and make new friends. Second, volunteering can make up for the loss of meaning that commonly occurs with loneliness. Research using the UCLA Loneliness Scale and Meaning in Life Questionnaire has shown that more loneliness is associated with less meaning. This makes sense, given our deeply rooted need for belonging. By volunteering for social causes that are important to us, we can gain a sense of purpose, which in turn may shield us from negative health outcomes. For example, purpose in life has been linked to a reduced likelihood of stroke and greater psychological well-being. Third, loneliness and isolation can lead to cognitive decline, such as memory loss. But according to the neuroscientist Lisa Genova, people who regularly engage in mentally stimulating activities build up more neural connections and are subsequently more resilient to symptoms of Alzheimer's. So, volunteering is one way to stay engaged and stimulated, rather than isolated and lonely, and thereby protect against cognitive decline.
