Loneliness and social isolation reduce years of mental health

Loneliness and social isolation significantly reduce the number of healthy years individuals experience, Science Daily Exercise and Science Daily reported on October 10, 2026. A large study found that men who experience both loneliness and social isolation lose about 5.8 years free from depression and anxiety. Women experiencing both conditions lose roughly 3.7 years of mental health. [1][2]

The findings highlight widespread social challenges across the United States. According to Science Daily Exercise, a 2023 report indicates that about half of adults in the United States experience loneliness. Nearly as many adults are affected by social isolation. Despite health consequences that rival major risk factors, both conditions remain relatively overlooked as public health concerns. [1]

Loneliness affects approximately 32 percent of adults in recent United States surveys, with moderate to severe forms reported by 37 percent in certain cohorts. Personality traits such as high neuroticism and low extraversion predict the onset of loneliness. Situational factors including bereavement, relocation, or prolonged unemployment also trigger the condition. [4]
