Loneliness and social isolation carry real health risks, but the popular claim that loneliness equals smoking 15 cigarettes a day is a simplified version of the research. The original comparison was about social connection and the risk of early death, and it said "up to."

## Where the claim comes from

In 2010, Julianne Holt-Lunstad and colleagues combined 148 studies with more than 300,000 participants. People with weaker social relationships had a higher risk of dying during the study periods. People with stronger relationships had about a 50% greater likelihood of survival.

The researchers then compared that size of risk to other known risk factors. Lacking social connection landed in a similar range to smoking up to 15 cigarettes a day.

In 2023, U.S. Surgeon General Vivek Murthy cited this research in an advisory on loneliness and isolation, saying a lack of social connection can raise the risk of early death as much as smoking up to 15 cigarettes a day.

## What the claim gets wrong

The headline drops "up to" and turns a comparison of mortality risk into a statement about overall health. It also blurs loneliness, the feeling of being alone, with social isolation, the fact of having few connections. Those aren't the same thing. Critics have also noted that a vivid comparison can add shame for people who already feel lonely.

## What still holds

Even without the exaggeration, the finding is serious. Weak social connection is linked to higher risk of early death in study after study. You don't need the cigarette line to take friendship seriously.

## The habit: guard against drift

Loneliness often grows quietly, through moves, job changes, new babies or retirement. The fix is rarely dramatic. It's small, regular contact.

- Reach out to one person each week.
- Say yes to invitations more often than feels natural.
- Join one group that meets regularly.

## The rule that makes it stick: make connection a routine

Don't wait until you feel lonely to reach out. Build contact into your week ahead of time, such as a standing call, a weekly service or a monthly dinner.

## This week

Text one person you haven't talked to in months and suggest a time to catch up.

## The keep

Reaching out takes a little courage and a little time. It builds a life that stays connected through every season.
