What Loneliness Is Doing To Your Heart

Posted on July 18, 2016

You may have heard that loneliness is hazardous to your health - and can even lead to an early death. Now, an analysis of 23 scientific studies gives us numbers that reveal just how sick it can really make you.

People with "poor social relationships" had a 29% higher risk of newly diagnosed heart disease and a 32% higher risk of stroke.

That puts loneliness and social isolation on par with other known risk factors for cardiovascular disease, such as anxiety and job strain, the researchers said. And it exceeds the risk posed by physical inactivity and obesity, said lead researcher Nicole Valtorta, of the Department of Health Sciences, University of York, England.

Loneliness and social isolation do not necessarily go hand in hand. You can be lonely in a crowd, or you can be by yourself and feel perfectly content. But when your experience is negative — you are not happy with the quality of your social interactions, or you’re grieving a loss — that “can be really disastrous for well-being,” Valtorta said.

Unlike other studies, Valtorta’s (which was published online in April) was the first to focus on whether people experiencing loneliness and isolation were at greater risk of developing cardiovascular disease. It excluded people who were lonely but already had the disease.

Studies involving 181,000 people living mainly in the U.S., Europe and Japan were examined as a part of the meta-analysis, and they were tracked for a range of time — between three and 21 years. Among those people, there were 4,628 heart attacks or related events and 3,002 strokes.
