What is the toll of loneliness on health in the US?
Loneliness and social isolation may cost people years of healthy life, with a significant toll on mental health.
According to a 2023 report, about half of U.S. adults experience loneliness, while nearly as many are socially isolated.
Who is affected by loneliness and social isolation?
Researchers at Tulane University's Celia Scott Weatherhead School of Public and Tropical Medicine found that loneliness and social isolation were associated with the loss of nearly six years of life free from mental disorders.
The effects on physical health were smaller, but still significant, with women experiencing both loneliness and social isolation having 2.4 fewer years free from physical disease, and men having 1.7 fewer years.
By the numbers
- 277,489 adults between the ages of 40 and 69 participated in the study.
- 6 years of healthy life may be lost due to loneliness and social isolation.
- 3.7 fewer years without mental disorders for women experiencing both loneliness and social isolation.
- 5.8 fewer years without mental disorders for men experiencing both loneliness and social isolation.
What the study found about loneliness and social isolation
The study found that social isolation and loneliness can have a significant impact on disease-free life expectancy, including both physical and mental disease.
Lead author Lu Qi said, 'This includes both physical and mental disease.'
How lifestyle affects loneliness and social isolation
The researchers also examined whether lifestyle could alter these associations.
Healthier habits, including better diet, regular exercise, sufficient sleep, and not smoking, measurably reduced the loss of disease-free years associated with social isolation.
However, a healthier lifestyle did not significantly reduce the additional health risks linked to feeling lonely.
What's next for the research on loneliness and health
The research team plans to study additional population groups in the future and use clinical trials to investigate whether loneliness and social isolation directly cause the health effects observed in the study.
