"I'm just not a people person"

Gene·Saturday, October 3, 2026 Edition

DINNER FOR ONE, AGAIN

Reuben Achterberg gets home around seven, drops his keys in the bowl by the door, and turns the television on before he's even put down his bag. Not for anything specific. The apartment is a one-bedroom in a mid-rise near the freight district, and the walls carry sound oddly. He eats standing at the counter. The TV hums. He would not describe himself as lonely. He would say he's an introvert, that he likes his own company, that he's just a bit tired lately.

The body doesn't accept that framing. Loneliness runs the same biological playbook as a threat you can see coming — sustained, low-grade, and slowly expensive. It elevates cortisol. It shortens sleep. It produces the kind of chronic inflammation that cardiologists and oncologists spend careers treating downstream. The research on this is not subtle: prolonged social isolation carries health risks comparable to smoking around fifteen cigarettes a day. That is not a metaphor for sadness. It is a physiological load.

Julianne Holt-Lunstad, a psychologist whose work on social connection and mortality has shaped how researchers think about the subject, found in a large analysis of existing studies that people with strong social relationships had a significantly higher likelihood of survival compared to those who were isolated. The effect held across age groups, health conditions, and countries. What predicted longevity wasn't wealth or exercise alone. It was whether people had other people.

THE CONTACT YOU KEEP SKIPPING

Most evenings you have a version of this choice, and it doesn't look like a health decision. It looks like whether to answer that message or let it sit. Whether to suggest grabbing a coffee or assume the other person is busy. The resistance is real — you're tired, and reaching out takes a kind of small courage that feels disproportionate to the stakes. But your body is keeping a different ledger. Every skipped contact is another evening where no one knows quite how you are. Reuben probably knows, somewhere in him, that the TV isn't company.

The body doesn't lie to protect your self-image. If you've been calling it introversion for long enough, the question worth sitting with is whether that's a preference or just something that got easier to say than the alternative.

Send one message this week to someone you haven't spoken to in over a month — not to catch up, just to say something true. Notice whether relief or resistance comes first. That ratio tells you something.

Key Facts

*Chronic loneliness triggers the same inflammatory stress response as physical danger, which over time degrades cardiovascular and immune health.

*Social connection doesn't require depth or quantity — even one consistent, low-pressure human contact has measurable protective effects on health outcomes.

*Reframing isolation as a health behaviour, rather than a personality preference, gives you the leverage to change it the way you'd change any other habit.
