Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

U.S. adults who experience high levels of social isolation have a 143% higher risk of dying from any cause compared to those who are less isolated, even if they have no prior heart disease.

See the scientific wording

Among U.S. adults without preexisting cardiovascular disease, high social isolation is associated with a 143% increased risk of all-cause mortality, suggesting its impact extends beyond cardiovascular pathways.

Why this might work

When someone is very lonely for a long time, their body stays in a state of stress, which causes more inflammation and weakens the immune system over time, making it harder to fight off diseases and increasing the chance of dying from any cause.

    People who feel very lonely are more likely to die sooner, even if they don’t have heart problems — this study shows loneliness can be just as dangerous as having a disease.
