Many Americans feel lonely.
That's according to a survey of more than 20,000 adults conducted by the Cigna insurance company.
Nearly half of the respondents said they sometimes or always feel alone or left out.
And about half said they have meaningful in-person social interactions on a daily basis.
Surprisingly, young adults were lonelier than older generations.
Studies show loneliness is linked to a higher risk of heart disease, stroke, and early death.
Nearly half of Americans report sometimes or always feeling alone (46 percent) or left out (47 percent).
One in four Americans (27 percent) rarely or never feel as though there are people who really understand them.
Two in five Americans sometimes or always feel that their relationships are not meaningful (43 percent) and that they are isolated from others (43 percent).
One in five people report they rarely or never feel close to people (20 percent) or feel like there are people they can talk to (18 percent).
Americans who live with others are less likely to be lonely (average loneliness score of 43.5) compared to those who live alone (46.4). However, this does not apply to single parents/guardians (average loneliness score of 48.2) – even though they live with children, they are more likely to be lonely.
Only around half of Americans (53 percent) have meaningful in-person social interactions, such as having an extended conversation with a friend or spending quality time with family, on a daily basis.
Generation Z (adults ages 18-22) is the loneliest generation and claims to be in worse health than older generations.
Social media use alone is not a predictor of loneliness; respondents defined as very heavy users of social media have a loneliness score (43.5) that is not markedly different from the score of those who never use social media (41.7).
