Being unhappy or lonely might age you faster, according to the findings of a new study published in the journal Aging. Researchers collected data on more than 4,400 Chinese adults over the age of 45, looking at social and economic status, health history, biometrics and blood sample data. They also collected responses to 8 markers of their psychological states. The researchers found that being on the lower end of a psychological well-being scale, especially feeling lonely or unhappy, has the effect of speeding up the aging process by more than 1.5 years. This aging effect from loneliness or unhappiness was stronger than the effects of biological sex, living area, marital status, and smoking status.
