In order to investigate the effects of deep sea water bathing on relaxation and daylight sleep in night shift workers, electroencephalography, circulatory and cardiac autonomic functionings, visual evoked potential, biochemical markers in urine and saliva, core body temperature, sleep questionnaires, and mood state questionnaires were evaluated in nine subjects to compare with other three kinds of bathing including sham (no water), tap water and surface sea water. Deep sea water bathing showed better subjective sleep latency for sleep questionnaire (p<0.1) and significantly better vigor status for mood questionnaire (p<0.01) between four kinds of bathing. With regard to the objective data, despite the biggest increase in temperature of eardrum in deep sea water bathing, the highest sleep efficiency and the shortest wake period during sleep in electroencephalography did not reach to the significant level.
The composition of human body can be divided into five levels (atomic, molecular, cellular, tissue, and body). The objective of this study is to examine the changes with age in total body water (TBW) and fat mass (FM), which are conductive factors in the body, on the tissue level. The subjects of this study consisted of 476 healthy energetic adults living in Aomori Prefecture, Japan (146 males and 330 females). The total and partial body water and fat mass were measured by segmental bioelectrical impedance analysis. The following results were obtained after adding examination of changes in body composition with age. 1. Both males and females in their 30s showed the highest values of fat-free mass (FFM) and TBW; those in their 60s showed the highest values of %FAT and FM. 2. TBW, a thermal-conduction-promoting factor, was higher in males, and FM, thermal-conduction-inhibiting factor, was higher in females. 3. TBW in the extremities, especially in the lower extremities, tended to decrease with age both in males and females. 4. TBW in the extremities associated with the conductivity of a warm bath was higher in the lower extremities, so understanding TBW in the lower extremities can be considered very important when determining the applicability of warm bathing.
We investigated the influences of hot-spring bathing on the incidences of abortion and premature birth using questionnaires returned from 768 puerperal in-patients. These patients were classified into four groups: 24 taking a hot-spring bath daily (group 1), 134 taking a bath with additives (group 2), 178 taking a plain water bath daily (group 3), and 35 taking a shower daily (group 4). The incidence of threatened abortion among the ambulatory patients in each group was 4.2% for group 1, 11.9% for group 2, 9% for group 3, and 2.9% for group 4. The incidence of threatened abortion among the hospitalized patients in each group was 4.2% for group 1, 6.7% for group 2, 4.5% for group 3, and 8.6% for group 4. The incidence of threatened premature birth among the ambulatory patients in each group was 12.5% for group 1, 17.2% for group 2, 15.7% for group 3, and 14.3% for group 4. The incidence of threatened premature birth among the hospitalized patients in each group was 0% for group 1, 7.5% for group 2, 3.4% for group 3, and 2.9% for group 4. The incidence of vaginitis among the patients in each group was 50% for group 1, 43.4% for group 2, 46.6% for group 3, and 44.1% for group 4. The incidence of premature rupture of membrane (PROM) among the patients in each group was 4.2% for group 1, 21.1% for group 2, 12.9% for group 3, and 22.9% for group 4. The incidence of premature birth among the patients in each group was 0% for group 1, 3% for group 2, 2.8% for group 3, and 2.9% for group 4. Among the 42 multiparas experiencing single delivery and being treated for threatened abortion, those who for more than 10 minutes daily showed a significant difference from ambulatory patients being treated for threatened abortion that required hospitalization. Many of the 63 primiparas who did not use a labor accelerating medicine but bathed for more than 10 minutes daily delivered their babies within 1000 minutes. Conclusion The above suggests that pregnant women may bathe in hot-springs without problem but bathing for less than 10 minutes is recommended during early stage of pregnancy.
The largest percentage of patients receiving acupuncture treatment in Japan are those with chronic aches. Aches are major factors of QOL, and the pain-killing effect of acupuncture treatment has a large clinical significance. In the study, therefore, we expressed the QOL of the patients who received acupuncture treatment as scores using SF-36 and then examined the effect of acupuncture treatment on improving the QOL. Each score of SF-36 was rated from 0 to 100, where higher points represent better states of health. The study was conducted on 60 patients who received acupuncture treatment in our facility from Oct. 2002 to Jan. 2003. All scores before the start of treatment were low, and all score fell below the national standard value. Physical functions (PF), bodily pain (BP), and generally view of healthiness (GH) of the physical component summary (PCS) and vitality (VT) of mental component summary (MCS) showed particularly low scores relative to other scores. Comparison of scores before the start of treatment with those 1 month after the treatment revealed that BP among the eight sub-scales was improved significantly (p<0.05). In conclusion, these results suggest that receiving acupuncture treatment can contribute to improving a patient's QOL.
