Loneliness among Americans has reached “epidemic levels,” according to health service company Cigna’s U.S. Loneliness Index, released Tuesday of last week.

The index, which surveyed over 20,000 U.S. adults, found that nearly half of survey respondents reported sometimes or always feeling alone (46 percent) or left out (47 percent) and younger generations feel much lonelier than older ones.

The survey also revealed that striking the right work-life balance can combat feelings of isolation, with those working less than desired actually feeling lonelier than those working more than desired.
