This cross-sectional analysis was conducted to assess the relationship between objectively measured hot water bathing and depressive symptoms in older adults. Community-dwelling older volunteers (n = 1,103; mean age: 72.0 years) took part in this analysis. Bathing conditions and distal skin temperature were assessed for two consecutive days. Researchers defined depressive symptoms as the 15-item Geriatric Depression Scale score of ≥6. Lower odds of depressive symptoms were observed in relation to both a higher frequency of hot water bathing and shorter interval from bathing to bedtime.
