Large cohort studies link loneliness and social isolation to higher rates of depression, cardiovascular disease and earlier death. The direction runs both ways: low mood pulls people away from others. Quality of connection matters more than the number of contacts.

Small moves that count

Regular low-pressure contact: a weekly walk, class or volunteering slot.
Telling one person how things actually are.
Treating withdrawal as a symptom to notice, not a preference to honour.
Social prescribing through the GP can connect people to local groups.

Loneliness is common and not a personal failing. If it comes with persistent low mood, it is worth raising with a GP alongside the practical steps.

If you or someone else cannot stay safe, call 999. Samaritans: 116 123, free, 24 hours.
