Distinct influence of everyday noise on cardiovascular stress

High-intensity environmental noise is known to be detrimental cardiovascular health. However, individual differences have not been considered, and reported effects cannot generalized levels reflecting everyday life. Here, we explore the relationship between daily-life sound exposure heart rate with longitudinal data from ten individuals across three weeks. We analyze daily short-term covariation changes in intensity using multi-level regression Granger analysis. find strong evidence that related all participants. Sound linearly positively rate, while ambient signal-to-noise ratio has a negative association louder environments. Across participants establish distinct temporal pattern of causality stronger influence environment on 6:00 hrs 16:00 than for rest afternoon/evening. propose sensitivity measures represent combination amount effort asserted listen under noisy conditions during active periods day direct physiological sound-induced stress reaction. A thorough understanding both factors necessary determine full extent which long-term
