Loneliness 101 – Why is loneliness a big deal?

Have you ever felt lonely while surrounded by people? Loneliness is often associated with a lack of social connection. Yet in my counselling work with people experiencing loneliness, a lack of meaningful connection can be just one part of a more complicated picture. To understand why we feel lonely and whether it’s okay to feel lonely, it helps to look at how ideas about loneliness have changed over time.

A Brief History of Loneliness

Before the 19th century, words such as “lonely” and “solitude” were often used to describe the physical state of being alone. Solitude could be seen positively as an opportunity to study, reflect, or connect with one’s faith. In the 19th century, industrialization and urban growth drew people away from family and settled communities. Many moved for work and found themselves among larger numbers of strangers. A person could feel isolated even while surrounded by people.

In the early 20th century, individualism and consumer culture placed increasing emphasis on personal success. Loneliness could come to feel like a personal failure or a sign of being socially maladjusted. New technologies, including telephones and televisions, were also promoted as ways to ease isolation. Today, loneliness is often discussed as a health and social concern.

Modern Loneliness

Having more ways to meet people does not always mean feeling connected. Someone might join a meetup group or use a dating app and still feel lonely. Loneliness can involve missing relationships, but it can also involve feeling unseen, cut off from the world, or unable to find belonging or purpose. Its roots may lie in personal circumstances as well as in the wider conditions people live under.

Loss or change in close relationships, major life transitions, mental or physical health difficulties, social anxiety, shame, and feeling misunderstood can all contribute to loneliness.

Why Does Loneliness Matter?

Loneliness is painful in its own right. When it persists, it is associated with a higher risk of depression and anxiety, and with poorer physical health, including cardiovascular problems and cognitive decline. The World Health Organization’s 2025 report estimates that about one in six people worldwide experience loneliness and identifies it as a significant health and social concern.

Loneliness matters in counselling because it can reflect what someone is going through and make it harder to cope. It may accompany grief, exclusion, health problems, or a disrupted sense of belonging. A person who feels lonely may also withdraw or expect rejection, which can make it harder to reach out and deepen the feeling of disconnection.

Is It Wrong to Want Time Alone?

Wanting time alone and wanting connection can coexist. Solitude can give us space to rest, think, and feel like ourselves. Loneliness may arise when time alone stops feeling chosen and starts feeling like disconnection. The challenge is to protect the quiet we need while staying connected in ways that feel comfortable and meaningful.

Attachment theory offers one way to understand how safe we feel reaching for closeness. Early caregiving experiences can shape our expectations about whether others will be available and responsive, and how comfortable we feel depending on them. If someone expects rejection or unavailability, they may seek frequent reassurance or protect themselves by keeping their distance. Either response can make it harder to feel secure and understood, even when other people are present. Attachment theory is one perspective on loneliness, rather than a complete explanation.

Loneliness may reflect not only how much contact we have, but also how safe and at ease we feel reaching for closeness.
