There may be something you’ve wanted to do for a while. A small exhibition. Music on a Thursday. Coffee somewhere new. The idea is there; the shared plan hasn’t happened yet.
Schedules do not line up. A familiar person lives further away now. Sometimes suggesting something feels like more work than the outing itself. An ordinary plan is a reasonable place to begin.
There is also a larger reason to take connection seriously: decades of research into how relationships relate to our wellbeing and health.
Different kinds of together
Connection is more than a headcount. WHO describes it through our relationships and interactions, the support they provide and their quality. The terms researchers use describe different parts of that picture. WHO’s explanation
- Loneliness
- The gap between the connection you want and the connection you feel.
- Social isolation
- Having too few relationships or interactions with other people.
- Living alone
- A household arrangement. It does not tell us how connected someone feels.
You can feel lonely in company, or connected while living alone.
You do not need to choose a label before deciding that you would enjoy company for something. Nor does enjoying an afternoon alone mean there is a problem to solve.
What the longer studies found
In 2010, Julianne Holt-Lunstad, Timothy Smith and Bradley Layton combined 148 studies involving 308,849 participants. Stronger social relationships were associated with greater odds of surviving the studies’ follow-up periods. The pooled odds ratio was 1.50. That is a comparison of survival odds, not a finding that people lived 50% longer. Original study
A 2015 review by Holt-Lunstad and colleagues examined loneliness, social isolation and living alone separately. Each was associated with higher mortality odds after adjustment for measured factors. A later review of 90 cohorts, published in 2023, also found associations between loneliness, isolation and mortality. The exact estimates vary with the studies and measures used. 2015 review · 2023 review
An association is not a promise
These findings deserve attention, but they cannot tell an individual how many years a new friendship would add. Poor health can make social contact harder. Other circumstances can affect both relationships and health. Adjusting for measured differences helps researchers investigate the question; it does not remove every alternative explanation.
Research continues to test those explanations. A July 2026 study combined observational, sibling-comparison and genetically informed approaches. Evidence was clearer for mental health and wellbeing than for specific physical diseases, with uncertainty remaining around some effects. The researchers cautioned that an uncertain result does not prove there is no effect. 2026 study
Studies of interventions ask another question: what happens when people receive a particular kind of support? A recent review found benefits across some approaches, while grading confidence in the estimates as low or very low. A membership built around shared plans is not interchangeable with those interventions. Intervention review
Back to everyday life
We can value company without turning every outing into a health project.
Perhaps someone you know would enjoy an exhibition. Perhaps the manageable plan is a short coffee, with the time and place easy to agree. An activity can be worthwhile on its own, with room for conversation around it.
Time, cost, transport, energy and accessibility can all shape what feels possible. A useful suggestion leaves room for those realities, and for someone to pass.
Bluedoor is being built around that practical beginning: private Invitations for shared experiences. Members choose whether an Invitation interests them, and a selected plan requires the relevant people to agree before protected meeting details and contact are shared. We have not established that using Bluedoor improves health, reduces loneliness or extends life.
What we are working toward is simpler to describe: helping adults give something they would enjoy a shape they can share.
