ABSTRACT

The purpose of this study was to clarify the relationship between frequency of bathing in a spa and at home and the characteristics of the body, blood, and lifestyle of white-collar and blue-collar male employees.<br>To recruit subjects, two baseline data for randomized controlled trials in two places in Shimane Prefecture and in Nagano Prefecture were used. In the two-month period between August and September 2006, 43 of 311 white-collar male employees aged between 30 and 57 years in the Unnan municipal office volunteered to participate in this study. Similarly, 44 blue-collar workers in Nagano Prefecture volunteered to be involved in this study as a result of an appeal for volunteers in local newspapers and public information journals published by large local enterprises from September through November 2006. A total of 87 men were subjects of this study. Items evaluated in this study with respect to physique included height, weight, body mass index, waist circumference, hip circumference, and percent of body fat. With respect to strength, they were grip strength, abdominal strength, back strength, and anteflexion. With respect to characteristics of the blood, they were serum glucose, hemoglobin A1c, fructosamine, lactic acid, total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, free fatty acid, GOT, GPT, γ-GTP, cholinesterase, natural killer cell activity, T cell, B cell, CD4+, CD8+, CD4/8 and uric acid. With respect to mood, Profile of Mood States was evaluated. With respect to lifestyle, the frequency of monthly bathing in a spa and at home was evaluated.<br>No significant correlation was revealed between frequency of monthly spa bathing and the health indices in the white and blue-collar male workers. The items that were significantly correlated (p<0.05) with frequency of monthly bathing at home were GOT (positive), CD8+ (positive), and mental stress (negative).<br>In this study, frequency of monthly spa bathing was found to have no significant correlation with the health indices.
