Description
<p>[Background]</p><p>Taking a hot bath with a bath additive is known to be relaxing. However, differences in body temperature change between young adults and the elderly and details of their bathing methods are not known. Therefore, we investigated their method of bathing for relaxation.</p><p>[Methods]</p><p>Participants were 30 men and 28 women aged 20 to 69 years. They took a full bath in 40℃ water for 15 min and rested for 30 min afterward. Sublingual temperature was measured every 5 min from the start to the end of bathing. Salivary amylase activity and subjective relaxation were measured before and after bathing.</p><p>[Results]</p><p>The participants were divided into three groups by body temperature change after bathing for 15 min: low, moderate, and high. Saliva amylase activity decreased in only the moderate-change group after bathing, and subjective relaxation was higher in the moderate-change group than in the other groups. Body temperature change due to bathing was negatively correlated with age and body fat percentage. The increase in body temperature was higher in men than in women.</p><p>[Discussion]</p><p>Raising body temperature by about 1.1℃ during bathing was a relaxing bathing method. Changes in body temperature during bathing were affected by age, body shape, and sex, and so the time needed for a relaxing bath with a 1.1 °C body temperature increase was estimated based on these factors. Understanding the appropriate bathing time for relaxation can contribute to the safety of bathing by preventing heat-related illness.</p>
