The Claim
In U.S. adults, high social isolation (scores of 3–4) is associated with a 65% increased risk of all-cause mortality over follow-up, independent of age, sex, socioeconomic status, smoking, and preexisting cardiovascular disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
U.S. adults who report high levels of social isolation have a 65% higher risk of dying from any cause during the study period, even after accounting for factors like age, sex, income, smoking, and heart disease.

When someone feels very alone for a long time, their body stays in a state of high stress, which causes more stress hormones to be released. These hormones mess with the immune system, making it overactive and causing low-level swelling throughout the body. Over time, this swelling damages blood vessels and organs, increasing the chance of serious illness or death.
What the research says
1 studyPeople who feel very lonely or disconnected from others were found to be much more likely to die sooner, even when accounting for things like age, smoking, or heart disease — just like the claim says.
