Strong social ties are one of the things most consistently linked to a long, healthy life, and the whole of it is free. Across 148 studies and more than 300,000 people, those with stronger relationships were about 50% more likely to be alive when follow-up ended, and poor social relationships track with higher rates of heart disease and dementia. That evidence is observational: it follows people over years and does not give anyone more company, and part of the raw risk is underlying illness pushing people into isolation, not isolation shortening a life. Part of it, not all.
Two things get measured here and they behave differently: isolation is being alone, loneliness is feeling alone, and both matter. Loneliness responds to help. The approaches that address the thoughts behind it work better than simply arranging more contact, and volunteering and shared purpose track with living longer too.
Findings & Outcomes
What It Is
Social connection is time spent in relationships that recur: seeing the same people, belonging to something, and having at least one person you can speak plainly to. Two things sit underneath that word and they are not the same. Social isolation is the objective state of being alone, a count of who you live with, how often you see people, and whether you belong to anything. Loneliness is the subjective feeling of being alone, the gap between the relationships you have and the ones you want.
A person can live alone, see friends every week and feel content, and a person can be surrounded by family and still feel unreachable. Both track with health, and they track differently, which is why the rest of this page keeps them apart.
Loneliness is usually the result of a circumstance, and the list is long and mostly outside anyone's control:
- grief, and the loss of the routine that went with a person
- caregiving
- chronic illness and pain
- hearing loss that makes group conversation exhausting
- moving to a new city
- shift work
- a low income that quietly restricts every way adults keep friendships going
- caring for young children
None of that is a personal failing.
What the Evidence Shows
The central finding is large and it is observational. Across 148 studies and more than 300,000 people, those with stronger social relationships had about 50% higher odds of being alive at follow-up. Poor social relationships also track with roughly a quarter to a third higher risk of death in later reviews, with about 29% more coronary heart disease and 32% more stroke, and with higher rates of later dementia. These are associations drawn from watching large groups, not from trials that assigned anyone more company, so the effect holds as a pattern and cannot on its own settle cause.
The confounding is stronger here than for most health habits. Illness makes people withdraw before it shortens a life. Loss of interest in others is a feature of depression, not merely a side effect of it. The changes that arrive years before a dementia diagnosis make company harder long before anyone is diagnosed. Any study that measures relationships once and counts deaths afterward will pick some of this up as though isolation shortened the life, when the illness came first.
The better cohorts handle this by adjusting for baseline health and circumstance and by following people long enough for existing illness to surface. When they do, part of the raw association shrinks and part of it holds. In nearly 467,000 UK adults, the isolation-to-death link fell from a hazard ratio of 1.73 to 1.26 after full adjustment and stayed there, while the feeling of loneliness fell to a null once the same adjustments were made. The same split appears for dementia: isolation kept predicting risk after heavy adjustment, and about three-quarters of the loneliness link ran through depressive symptoms measured alongside it.
The structural side of a social life survives adjustment while the felt side often does not, so the practical effort belongs on who you actually see and belong to, not on trying to feel differently on command.
The findings below are each graded at the strength of their own evidence.

Social Connection
Stronger relationships tracked with 50% higher odds of survival across 148 studies
Across 148 studies and more than 300,000 people, those with stronger relationships were about 50% more likely to be alive when follow-up ended. It is a large association and it is observational: the studies followed people, they did not give anyone more friends, and illness itself pushes people into isolation. The signal is bigger when relationships are measured in several dimensions at once than when it comes down to whether someone lives alone.
Odds ratio 1.50 (95% CI 1.42 to 1.59); mean age 64, mean follow-up 7.5 years. Multidimensional measures of social integration gave 1.91, while the crude single question of living alone gave 1.19 with an interval crossing 1. Odds of survival is not the same quantity as a reduction in the risk of death, and the two are swapped constantly in retellings. Illness, depression and poverty all shrink a network before they shorten a life, so which way the causation runs is unresolved.
Who this may not transfer to:Roughly balanced by sex, and the effect was independent of it.
The measures that carried the strongest signal counted participation and belonging over time, which is why the practical unit is a repeating slot in the week rather than a raw headcount.

Isolation, loneliness and living alone each tracked with 26 to 32% higher odds of death
Pooling studies from 1980 to 2014, people who were socially isolated, lonely, or living alone were roughly a quarter to a third more likely to die over follow-up. This review found no difference between the objective measures and the felt ones, and the effect was actually stronger below age 65 than above it.
Weighted average effects with confounders controlled: social isolation OR 1.29, loneliness OR 1.26, living alone OR 1.32, corresponding to 29%, 26% and 32% higher likelihood of death. Objective and subjective measures did not differ. Results were stronger in samples with a mean age under 65 than in older ones, and baseline health status influenced the size of the association, which is the reverse-causation problem surfacing inside the meta-analysis itself.
Who this may not transfer to:Gender was tested as a moderator and the results were consistent across it, as they were across follow-up length and world region.

After full adjustment the isolation-death link held at 1.26, while loneliness fell to a null
In nearly 467,000 UK adults, being socially isolated still predicted earlier death after accounting for health and circumstance, while the feeling of loneliness did not once the same adjustments were made.
Social isolation hazard ratio 1.73 (95% CI 1.65 to 1.82) adjusted only for age, sex, ethnicity and chronic disease, falling to 1.26 (1.20 to 1.33) after full adjustment. Loneliness ran 1.38 (1.30 to 1.47) minimally adjusted and 0.99 (0.93 to 1.06) fully adjusted, a measured null. The full adjustment included depressive symptoms, which is plausibly a step on the path from loneliness to death rather than a confounder, so the loneliness null is a ceiling on the direct effect rather than a measure of the whole one.
Who this may not transfer to:Men and women, with sex adjusted for in every model. UK Biobank volunteers are healthier and less deprived than the UK population, which tends to shrink observed associations.
The structural side of a social life, who you actually see and belong to, is the more robust thing to work on, since it is what survives adjustment.

The most isolated older adults were about 26% more likely to die, and loneliness added nothing to the model
In 6,500 older English adults, the most isolated fifth were about 26% more likely to die, and adding loneliness to the model did not change that, so loneliness was not the channel carrying isolation's effect.
After adjustment for demographics and baseline health, the most isolated fifth had a hazard ratio for death of 1.26 (95% CI 1.08 to 1.48). Loneliness in the same model gave 0.92 (0.78 to 1.09) and left the isolation estimate unchanged when added. Isolation was measured once at baseline from contact with family and friends plus civic participation, and a single measurement cannot capture a social life that shifts with health over seven years.
Who this may not transfer to:Men and women aged 52 and over. The published hazard ratios are pooled across sex rather than stratified.

Losing a spouse raised the risk of death about 23%, more for men than for women
Losing a spouse raised the risk of death about 23% on average, and the effect was larger for men than for women, with the gap shrinking as people got older.
Mean hazard ratio 1.23 (95% CI 1.19 to 1.28) among high-quality adjusted estimates, comparing widowed with married people; 1.27 (1.19 to 1.35) for men against 1.15 (1.08 to 1.22) for women. Drawn from 1,381 estimates across 124 publications and more than 500 million person-records. Magnitude also varied with sample size, region and level of adjustment, and a spouse's illness often precedes their death by years of caregiving, so the exposure period is not clean.
Who this may not transfer to:Estimates are reported separately for men and women, which is unusual in this literature and is why this row carries the sex finding for the page.
Bereavement is the one place where the effect splits clearly by sex, with men after losing a spouse the higher-risk group, so this is where extra contact and routine are worth deliberately rebuilding.

Talking therapy produced a small-to-medium drop in loneliness, g 0.43, across 28 trials
Talking therapies, most often group cognitive behavioral therapy delivered weekly, produced a small-to-medium drop in loneliness across 28 trials.
Loneliness fell against control groups with a pooled Hedges' g of 0.43 across 28 randomized trials (N = 3,039), most of them face to face, group based and weekly. Heterogeneity between trials was considerable and study quality was mixed on the Cochrane risk-of-bias tool. Type of intervention only approached significance as a moderator, so the pooled figure does not pin down which therapy does the work.
Who this may not transfer to:Participants came from a diverse range of cultures, age groups and populations; no sex-stratified pooled effect is reported.
These therapies treat the expectation of rejection and the effort that company takes, the same target as the social-cognition approach that performed best in the trial comparisons, which is why they are the route to reach for when contact itself feels unsafe rather than just tiring.

Targeting loneliness-driving thoughts cut it most, about 0.6 SD, while adding contact barely moved it
When loneliness is treated directly, the approaches that work best are the ones that change how a person reads social situations, not the ones that simply put more people in the room. Across the strongest trials the average change was small, and 14 of 20 showed none at all.
Across 20 randomized comparison studies the mean reduction in loneliness was 0.198 standard deviations (95% CI 0.08 to 0.32). Within that group, addressing maladaptive social cognition reduced loneliness by 0.598, about 0.6, (4 studies), enhancing social support by 0.162 (12 studies), improving social skills by 0.017 (2 studies, p = 0.90) and increasing opportunities for contact by 0.062 (2 studies, p = 0.67). This is a moderator analysis rather than a head-to-head trial, it reached significance at p = 0.05 exactly, the winning cell holds four studies, and effect sizes shrank steadily as designs got stronger.
Who this may not transfer to:The trial samples were mostly female, and the analysis reports no reliable sex-stratified effect. An earlier reading that women showed smaller loneliness reductions could not be confirmed in the paper and one passage indicates gender composition did not moderate the result, so no sex difference is claimed here.
If contact feels frightening rather than merely effortful, that appraisal is the target with the best evidence, and a therapist working in cognitive behavioral terms is the version of that with trials behind it. Putting a lonely person in a room with others is the approach that has failed most reliably.

Video calls made little to no measurable difference to loneliness in three nursing-home trials
Video calls made little to no measurable difference to loneliness in the three small nursing-home trials that tested them. For someone whose only alternative is no contact at all, though, a call is still contact.
Mean difference 0.44 points on the 20 to 80 point UCLA Loneliness Scale at three months (95% CI 3.28 better to 2.41 worse), 0.34 at six months and 2.40 at twelve, against usual care across 3 cluster quasi-randomized trials totaling 201 nursing-home residents. Certainty was downgraded three levels for study limitations, imprecision and indirectness, so this is closer to an absence of usable evidence than a demonstrated null. No included study reported social isolation as an outcome, and the population does not resemble most readers.
Who this may not transfer to:All participants were nursing-home residents with a mean age of at least 65. The review does not report a sex breakdown.
The useful distinction is between contact at the same time and contact that is not: a call or video call involves turn-taking and repair, so it works best as a supplement to seeing people rather than a full replacement for it, especially when in-person contact is out of reach.

Heart And Vascular
Poor social relationships tracked with 29% more heart disease and 32% more stroke
Poor social relationships were tied to about a 29% higher risk of heart disease and a 32% higher risk of stroke across 16 long-term datasets.
Pooled relative risk 1.29 (95% CI 1.04 to 1.59) for incident coronary heart disease and 1.32 (1.04 to 1.68) for stroke, over 4,628 coronary events and 3,002 strokes with follow-ups of 3 to 21 years. Both lower bounds sit near 1.04, so the pooled estimates are consistent with much smaller effects than those percentages suggest. The exposure mixed loneliness and isolation measures, and subclinical heart disease reduces activity and participation years before an event is recorded.
Who this may not transfer to:Subgroup analyzes did not identify any differences by gender. All included studies were set in high-income countries.

Cognition
Socially isolated people had about 26% higher dementia risk after heavy adjustment, loneliness none
In UK Biobank, socially isolated people had about a 26% higher risk of later dementia even after heavy adjustment, while loneliness did not predict it once depression was accounted for. Three-quarters of the loneliness-to-dementia link ran through depressive symptoms.
Social isolation hazard ratio 1.26 (95% CI 1.15 to 1.37) after adjustment for demographic, socioeconomic, biological, cognitive, behavioral and psychological factors including loneliness and depression; loneliness gave 1.04 (0.94 to 1.16), with 75% of its association attributable to depressive symptoms. Mean follow-up 11.7 years across 462,619 people. The dementia prodrome runs longer than most cohorts follow, so this length of follow-up does not remove reverse causation, and the supporting brain-imaging arm is cross-sectional.
Who this may not transfer to:Men and women, with sex adjusted for in every model and no sex-stratified estimate published. Same cohort as the mortality adjustment row, so the two are not independent replications of each other.

A poor social network tracked with 59% higher dementia risk across 2.3 million people
Pooling 33 cohorts and 2.3 million people, a poor social network raised dementia risk about 59% and weak social support about 28%, and over follow-ups of ten years or more good social engagement was modestly protective. Loneliness on its own did not reach significance.
Poor social network RR 1.59 (95% CI 1.31 to 1.96), poor social support RR 1.28 (1.01 to 1.62), and in studies following people 10 years or more, good social engagement RR 0.88 (0.80 to 0.96). Loneliness gave RR 1.38 with an interval of 0.98 to 1.94 that crosses 1, so a real loneliness effect is not excluded, only unproven at this power. The social support pooling showed substantial heterogeneity (I-squared 55.5%), meaning the studies behind it disagree.
Who this may not transfer to:The review does not report a sex breakdown across its 33 included studies, and no sex-stratified pooled estimate is given.

Longevity And Mortality
People who volunteer were about 22% less likely to die over follow-up
People who volunteer were about 22% less likely to die over follow-up across five pooled cohorts, and reported better mood and life satisfaction. The catch is that being well enough to volunteer is itself a sign of health, and trials did not confirm the mood benefits the cohorts showed.
Pooled relative risk of death 0.78 (95% CI 0.66 to 0.90) across five cohort studies. Cohorts also showed favorable effects on depression, life satisfaction and wellbeing but not on physical health, and the experimental studies did not confirm those wellbeing benefits. Five cohorts is a thin base for a mortality estimate, and healthy-volunteer selection is at its most literal here: being mobile, well and organized enough to commit to regular unpaid work is already a marker of health.
Who this may not transfer to:No sex-stratified mortality estimate is reported, and the review does not give an overall sex breakdown of the pooled cohorts.
Giving and shared activity is the route with a mortality cohort behind it, so where you have the capacity, doing something for others is a reasonable thing to lean toward, read as an association rather than a guarantee.

Mood & stress
Over five years, loneliness came before worsening low mood, not the other way around
Over five years, feeling lonely came before a worsening of low mood, while low mood did not come before loneliness. It is some of the clearest evidence that at least part of the harm runs from loneliness to illness rather than the other way around.
In cross-lagged panel models across 229 adults aged 50 to 68 in Chicago, loneliness predicted subsequent change in depressive symptoms while depressive symptoms did not predict subsequent change in loneliness. The ordering held after accounting for gender, ethnicity, education, physical functioning, medications, social network size, neuroticism, stressful life events, perceived stress and social support. Cross-lagged models establish temporal precedence rather than causation, the loneliness and depression scales share item content, and an unmeasured factor changing before both could produce the same ordering.
Who this may not transfer to:Men and women. Gender was tested as a possible influence on the cross-lagged association and did not account for it.

What Helps
When loneliness is treated directly, the approaches differ sharply in how well they work. Across the strongest trials the average change was small and most individual studies showed none. Within that set, the interventions that addressed the thoughts driving loneliness, the expectation of rejection and the reading of company as unsafe, worked several times better than the ones that simply increased opportunities for contact. Putting a lonely person in a room with others is the approach that has failed most reliably.
Talking therapy, most often group cognitive behavioral therapy delivered weekly, produced a small-to-medium drop in loneliness across 28 trials, and it targets that same appraisal. So when contact itself feels frightening, not merely tiring, the approach to reach for first is the one that changes how social situations are read.
For most people the situation is not fear, it is too few people in the week, and there the practical unit is regular, repeating contact, not the number of people. Volunteering is the one route here with a mortality cohort behind it, and it adds the pull of giving, not receiving, though being well enough to volunteer is itself a marker of health, so read the size of that finding gently.
Online contact has a place inside this too. A call or video call happens at the same time and involves turn-taking, so for someone whose alternative is no contact at all it still counts as contact. The direct trial evidence that video calls reduce loneliness is thin and drawn from nursing homes, so it works best as a supplement to seeing people, not a full replacement.
Ways to Do It
Start at whichever rung fits the week you actually have, given your circumstances, and hold it. Regularity is what the data tracks, not volume.
Pick one person you can say the true thing to, and make contact, a call over a typed message where you can, since a voice brings the turn-taking a message does not. Depth carries more than headcount in the loneliness measures, so one person you can be direct with does more for the feeling than ten acquaintances. If you already have that person, contact them more often, and you need not go looking for more people.
Something that repeats, with the same people: a weekly class, a choir, a team, a standing walk, a shift at the same place. Regular recurring contact is what the mortality studies tracked, because repetition is what turns an acquaintance into a familiar face. One reliable slot beats three you keep canceling. For a caregiver or someone housebound, a short call at the same time each day counts as the slot.
Shared activity asks less of you than conversation does, since doing something side by side removes the need to produce small talk, which is the barrier most people name. A sport, a garden, a workshop, a rehearsal, or volunteering, which is the route here with a mortality cohort behind it and the added pull of giving. Being well enough to volunteer is itself a marker of health, so read that finding gently, and pick the thing you would actually keep going back to.
How It Works
Anatomy of the Practice
1The stress response left switched on
Feeling unsafe among others, or having no one to share a load with, keeps the body low-level braced. Over years that shows up as higher blood pressure, higher stress hormones and higher markers of inflammation in isolated and lonely people. This is measured association, not a proven chain, since the same illnesses that raise these markers also thin out a social life, but it is the most likely route by which a feeling reaches the body.
2Health behaviors and a safety net
People who see others regularly tend to eat, move, sleep and take medicines more reliably, and someone is there to notice when they are unwell and get them to care sooner. Much of the survival difference between connected and isolated people may run through these ordinary mechanics, not through the biology of feeling connected, which is part of why the raw effect shrinks once behavior and circumstance are accounted for.
3Isolation is often the result, not the cause
Reverse causation is central here. Illness, depression, low income and the years-long prodrome before dementia all push people into isolation before they shorten a life or damage the brain. That confounding is why the observational findings on this page are read as patterns, not proof, and why the cleaner evidence, that loneliness comes before worsening low mood, not the other way around, matters as much as the size of any single number.
Go Deeper
- Depression: where losing interest in people is a symptom, not a social problem, and what helps.
- Anxiety: where contact brings dread, not tiredness, which is treatable and is the appraisal the best trials targeted.
- Doing hard things: why the steps that matter most, including reaching out first, tend to be the ones that ask something of you.
- Dementia: where staying socially engaged sits among the things linked to lower later risk, and what the evidence can and cannot say.
The Chinese Medicine View
Chinese medicine is a medicine of the person in front of the practitioner, so what it addresses here is someone's response to their situation, not the situation itself. The Heart is said to house the Shen, the whole of a person's mental and emotional presence, read in the eyes and in how someone holds a conversation. Joy and a sense of belonging are treated as nourishing to the Shen, and their absence as depleting, so connection is part of what keeps the spirit settled. When Heart Blood or Heart Yin runs short the Shen is described as unrooted: sleep breaks, the person startles easily, and company becomes tiring, not restoring, a picture set out on the Heart patterns page.
The seven emotions are treated as internal causes of illness, each with an effect on the Qi. Sorrow is said to disperse the Qi and is paired with the Lung, which is why prolonged grief is read as depleting Lung Qi and shows as a weak voice, shallow breathing and frequent sighing. Overthinking is said to knot the Qi and burden the Spleen, the pattern often assigned to rumination after a loss. Two classical presentations come close to what this page is about: visceral agitation, a person who is sorrowful and wants to weep for no reason they can name, treated with Gan Mai Da Zao Tang; and Lily Disease, someone who wants to eat but cannot, wants to rest but cannot settle, often following a shock or a febrile illness.
The tradition also declines to treat solitude as a problem in itself. A quiet person with a small circle who sleeps well, eats well and has energy is not a patient. It would hold back from pushing someone who is depleted, after illness, childbirth, surgery or a recent bereavement, into social effort; for that person the counsel is rest, warmth, food and time, with activity added back gradually. The two frames answer different questions, and neither one validates the other. The research can describe what happens across hundreds of thousands of people and cannot say what to do for the person in the room; the tradition can describe that person in detail and has never measured a population.
Cautions For This Practice
Everything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
When pulling away is depression, not a social problem
Losing interest in people, on its own or alongside low mood, poor sleep, loss of appetite or the sense that nothing is worth the effort, is a core feature of depression, and it responds to treatment for depression. If that is the shape of it, talk to a doctor before working on your calendar. The depression guide covers the options and what each one is worth.
If contact brings dread, not tiredness
Feeling fear before seeing people, physical symptoms at the thought of it, or planning your days to avoid it, is closer to anxiety than to loneliness. It is treatable, and the approach that changes how social situations are read is the one with the best trial evidence behind it. The anxiety guide is the place to start.
After a bereavement
Grief is not a problem to be fixed by getting out more, and the raised risk that follows losing a spouse is largest for men and in the first stretch after the loss. Rebuilding a little routine and regular contact at your own pace helps; being told to move on does not. If low mood, hopelessness or not eating persist for weeks, that has tipped into something worth taking to a doctor.
If you are thinking about harming yourself
Do not sit with this alone. Call your local emergency number or the crisis line your country publishes, and if someone is nearby, tell them and ask them to stay.
Sudden withdrawal in an older adult
Pulling away that comes on suddenly in an older person, especially alongside memory changes, getting lost, or losing the thread of conversations, calls for a medical assessment, not a social nudge, since it can be an early sign of something treatable.
New hearing loss
Hearing loss makes group conversation exhausting and is a common, treatable reason people quietly stop joining in. It is often missed for years, so check it if group settings have started to feel like too much work.
Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.
Common Questions
Is being lonely really as bad as smoking 15 cigarettes a day?
That figure is not in the research. The 2010 meta-analysis of 148 studies compared its effect with other risk factors and concluded the size is comparable with smoking as a risk factor and larger than obesity or physical inactivity. No count of cigarettes appears in the paper; that framing came from press coverage. The association is large and it is observational, so a per-cigarette equivalence is not something the data can support.
What is the difference between loneliness and social isolation?
Isolation is a count of contacts and memberships, the objective state of being alone. Loneliness is the felt gap between the relationships you have and the ones you want. They overlap loosely, so you can have one without the other. In the largest cohorts, isolation keeps predicting death and dementia after full adjustment while loneliness fades once depression is accounted for, and about three-quarters of the loneliness-to-dementia link ran through depressive symptoms measured at the same time.
Does making more friends actually make you live longer?
No trial has shown that, and none could easily be run. The mortality evidence is entirely observational, and illness, depression and poverty all push people into isolation before they shorten a life. What has actually been randomized is loneliness itself, where the average effect is small and, among the approaches tested, simply increasing opportunities for contact performed worst.
Does contact online count?
It counts when it happens at the same time as the other person. A call, a video call or a game played alongside someone involves turn-taking and repair, which is most of a conversation; reading about people online involves neither. For someone whose alternative is no contact at all, a call or video call is still contact. The direct trial evidence that video calls reduce loneliness is thin and comes from nursing homes, so online contact is best treated as a supplement to seeing people, not a full replacement.
I am lonely because of my situation, not my effort. What actually helps?
Pick one repeating commitment that fits the constraint and hold it, because regularity is what the data tracks, not volume. Shared activity beats conversation, since it removes the small talk that is the barrier most people name, and one person you can speak plainly to beats ten acquaintances. If contact feels frightening, not merely tiring, that appraisal is what the best-performing trials targeted, and it responds to treatment.
