Lonely people feel much worse when they catch a cold, a study reveals.
It found solitary adults report much more severe symptoms when they came down with an illness. Researchers claimed lonely people feel worse physically and mentally.
And it increases the risk of dying young by 26 percent, a similar effect as obesity.
To test the impact of our emotions on how we cope with sickness, scientists infected 160 adults with a cold.
They were then isolated for five days in hotel rooms.
Scientists found that participants who claimed they were lonely also reported feeling the most unwell.
“Put simply, lonelier people feel worse when they are sick than less lonely people," the study authors concluded.
Researcher Angie LeRoy, from by Rice University in Texas, said: “Loneliness puts people at risk for premature mortality and all kinds of other physical illnesses."
