Lonely people are more prone to developing high blood pressure in later life, say researchers. It has been found that chronic feelings of loneliness push up blood pressure over time, causing a marked increase after four years in people aged over 50, reports dailymail.co.uk.
A new study is the first to show a direct link between loneliness and high blood pressure, known as hypertension, which raises the risk of heart attack and stroke.
US researchers considered whether depression and stress were pushing up blood pressure but found they were only partly responsible.
"Loneliness behaved as though it is a unique health-risk factor in its own right," said Louise Hawkley, of the research team from Chicago University.
She said living alone did not necessarily mean people were lonely, as some people appeared to have busy lives and a good social network but still felt lonely, which puts them at risk.
Previous research has suggested that individuals who feel alone are twice as likely to develop Alzheimer's disease as those who experienced little loneliness.
