[Background]
Although Japanese are likely the most race to enter baths and hot springs in the world, there are few epidemiological studies on daily bathing for general residents. In this study, a questionnaire survey on the actual condition of bathing for residents in urban areas is aimed at presenting the appropriate healthy lifestyle with bathing in Japan.
[Methods]
We conducted a questionnaire survey on the actual condition of bathing for residents in urban areas. An effective response of 1,592 people was obtained. I compared this questionnaire with recent health checkup data. Metabolic syndrome was defined as a metabolic syndrome when using international standards and having three or more constitutive factors. The relationship between each element of bathing and the constituent factors of metabolic syndrome was analyzed using a logistic regression model by age and sex adjustment.
[Results]
Bathing entered almost every day was a majority. The group not bathing every day was the risk of metabolic syndrome in the summer. The tendency to use the shower in summer, the tendency to use for bathtub strong in winter. The bathing time was shorter in the summer, and the younger generation tended to be shorter. In the group with a bathing time of more than 20 minutes in the summer, the risk of metabolic syndrome was as low as 0.63. The bathing time zone was 40% in the summer season, especially for men taking a bath before dinner, and the women tended to enter before going to bed after dinner. On the other hand, the risk of metabolic syndrome was low in the group using the shower in winter. The thing to keep in mind for bathing is warming the bathroom, bathing water, wiping sweat a little earlier, but bringing water for hydration is brought in, in fact, it is hard to refrain from bathing when the blood pressure is high.
[Conclusion]
We will pursue further pursuits in the future, provide evidence of a causal relationship, and repeatedly take proof of proper bathing.
