WORK, FATIGUE, AND WELL-BEING - The Mediating Effect of Tiredness on Life Satisfaction in Older Adults

Sep 29, 2026

Research examines how older adults’ labor participation relates to life satisfaction, specifically whether tiredness mediates this association. Using 2019 Korea Time Use Survey data (n=6,570; 3,855 women, 2,726 men), findings show tiredness serves as a mediator between work hours and life satisfaction: longer work hours lower life satisfaction mainly by increasing fatigue. Total work hours alone do not significantly affect life satisfaction, underscoring tiredness as central. Results support fatigue-reduction interventions to improve well-being.
