As human beings, we have a strong need to belong and this need is a powerful driver for our behavior.
Attachment refers to the emotional bonds that we as children form with our caregivers, and as adults with other adults. When these bonds are reliable and warm, they give us a basic sense that “there are people for me” – people who care about our welfare, notice our absence, and are glad when we show up. Over time, this sense of being held in a stable web of relationships becomes part of how we see ourselves and the world, and quietly shapes the choices we make in work, family, and community life.
This fundamental “need to belong” is a near‑universal drive to form and maintain a minimum number of lasting, positive, and significant relationships that involve frequent, mostly pleasant contact and an underlying expectation of mutual care. We do not just want occasional company; we are wired to seek ongoing bonds in which others know us, think about our well‑being, and expect the relationship to continue into the foreseeable future. This is why people tend to form attachments readily (even in minimal or temporary groups), resist the loss of existing bonds, and often experience strong emotions when inclusion or exclusion is at stake.
Favorable attachments are known to buffer the association between life events and mental health. People who feel securely connected to family, friends, or a close confidant tend to cope better with stress, show fewer symptoms of depression and anxiety, and even display better physical health and immune functioning. Being part of a supportive network does not only help because others can offer practical help but it also directly reduces the psychological load of stress.
And a lack of attachment is linked to a variety of ill effects on health, adjustment, and well-being. Persistent loneliness, social isolation, or unstable relationships are associated with higher rates of mental illness, substance use, self‑harm, and even increased mortality across a range of medical conditions. Chronic deprivation of belonging keeps emotional stress systems activated, contributing over time to emotional exhaustion, poorer coping, and a greater vulnerability to life’s demands.
