Staying connected to family, friends and community can have a real impact on wellness at any age, and particularly in later life.

Older adults who socialize often have less stress, a stronger immune system, and generally demonstrate better health habits—they eat better, exercise more, don’t smoke and drink less. They also tend to feel more optimistic and hopeful. Friends also can help each other maintain a healthy lifestyle.

Some ways to build a social network include joining a community organization, getting a job, participating in a faith-based community, taking a class and volunteering. These can all be great ways to foster healthy relationships and add new levels of meaning to life.

Staying socially connected may lower the risk of depression. While depression is not a normal part of growing older, it does affect 15 percent of older Americans, or about six million people. Although there is no one cause of depression—genetics, differences in brain chemistry, and environment all play a role — feelings of emptiness or helplessness evoked by life events also can contribute to one’s risk for depression. Loss of a spouse or friends can lead to loneliness. Disabilities such as vision or hearing loss can also lead to feelings of isolation.
