The Effect of Stress on Optimal Bathing Time

Abstract

Along with advances in medical technology and improvement in living standards, personal daily health management has got more and more attention. Bathtub electrocardiogram (ECG) has become an important index of personal daily health management. A study is conducted with one participant on a daily basis over one year. Bathtub ECG is measured during his daily bathing and used for heart rate variability (HRV) analysis. HRV stress index (SI) and optimal bathing time are calculated. The data of low SI and high SI are selected to analyze the effect of stress on the optimal bathing time. The results show that the optimal bathing time is delayed and it takes longer to achieve the comfort of bathing in the case of high SI.
