Researchers Identify Shift in Emotional Distress Patterns, Highlighting Early Adulthood as New Peak
Recent research indicates a significant shift in the patterns of emotional distress across generations in the United States and other nations. A follow-up study published in PLOS ONE in 2025, analyzing CDC survey data from over 10 million U.S. adults and global surveys, found that the traditional midlife 'unhappiness hump' has largely vanished. Instead, measures of emotional distress now peak in early adulthood and gradually decline with age. This contrasts with a 2020 study in the Journal of Economic Behavior & Organization, which identified age 49 as the peak for anxiety, insomnia, and daily stress. The new findings suggest that economic realities and changing social structures are reshaping how emotional well-being is distributed across different age groups, with younger adults experiencing higher levels of distress.
