Although social media allow us to become more connected to other people than at any time in history，a new study suggests that many Americans feel lonelier than ever before，which is weakening the nation's mental and physical health.
The study conducted by the health insurer Cigna，found widespread loneliness，with nearly half of Americans reporting they feel alone，or left out at least some of the time.The nation's 75 million millennials( ages 23—37 ) and Generation Z adults( ages 18—22) are lonelier than older generations.Besides，54% of people surveyed said they feel no one knows them well，and four in 10 reported they “lack companionship”，their “relationships aren't meaningful” and they “are isolated(孤立的) from others”．
Douglas Nemecek，MD，Cigna's chief medical officer for Behavioral Health，said the findings of the study suggest that the problem has become common，equaling the risks caused by tobacco and the nation's everexpanding waistline.“Loneliness has the same influence on health as smoking 15 cigarettes a day，while obesity(肥胖) less than 10 cigarettes a day，” he said in releasing the report.
Nemecek's comments tallied_with those of other leading public health specialists，including former Surgeon General Vivek H．Murthy，MD，who said loneliness should be targeted in public health campaigns like those designed to fight against smoking and obesity.“During my years caring for patients，the worst disease I saw was not heart disease or diabetes；it was loneliness，” Murthy said in a recent cover story in the Harvard Business Review.
The new report，produced in Cigna's partnership with the polling company Ipsos，is based on an online survey of more than 20，000 US adults using the wellregarded UCLA Loneliness Scale to see how widespread loneliness is in America.
