Feeling lonely was linked to fewer years of good health in a UK Biobank study of 277,489 adults. At age 50, women and men who were both lonely and socially isolated lived 2.4 and 1.7 fewer years free of physical disease, and 3.7 and 5.8 fewer years free of depression or anxiety, than peers who were neither.[1] The study is observational, so it shows an association, not a cause.
What the researchers measured
The team followed adults who started free of seven major conditions: type 2 diabetes, cardiovascular disease, chronic respiratory disease, neurodegenerative disease, cancer, depression and anxiety. They separated two ideas that people often blend. Loneliness is how connected you feel. Social isolation is how few social contacts you have.[1]
Both were more strongly associated with life expectancy free of mental disorder than with life expectancy free of physical disease.[1] One finding stands out: the loss of disease-free years linked to social isolation narrowed in people with healthier lifestyles, but the matching association for loneliness was not statistically significant.[1] In plain terms, this study could not show that healthy habits offset the weight of feeling lonely, though a non-significant result does not prove they make no difference.
How to read it
Because people were not assigned to be lonely, other factors could explain part of the link, and poor health can also lead to loneliness. A longevity physician quoted by Prevention made the same point: the study suggests fewer healthy years, not that loneliness directly causes earlier death.
Practical ways to build connection
- Make connection recurring. A weekly walk, class, meal or standing phone call removes the need to feel like reaching out.
- Choose quality over quantity. One person who really listens counts for more than a crowded calendar. You can feel alone in a group.
- Notice avoidance. If you cancel plans when you feel low, that pattern keeps loneliness going. Keep the plan small, such as a 20-minute coffee.
- Treat it as a health item. Put connection on the same list as sleep and exercise, and tell your clinician if loneliness is lingering.
If loneliness comes with persistent sadness or anxiety, talk to a clinician or therapist. If you are in crisis, call or text 988, the Suicide & Crisis Lifeline, in the US.
