Background: The traditional Japanese style of soaking in a hot bath is a lifestyle custom for many citizens, no study had ever investigated the association between bathing as a lifestyle practice and the onset of long-term depression. Through a large-scale six-year longitudinal study, we aimed to determine whether tub bathing as a lifestyle custom plays a role in preventing the onset of long-term depression. Methods: Of 11,882 individuals who responded to surveys conducted in 2010 and 2016 as part of the Japan Gerontological Evaluation Study (the JAGES) project, we analyzed 6,452 and 6,465 individuals for whom information was available regarding summer bathing frequency and winter bathing frequency, respectively; all of these individuals were independent, had a Geriatric Depression Scale (hereafter, “GDS”) score of ≤4, and did not suffer from depression. The cohort study involved dividing participants into a group of those who bathed 0-6 times a week and a group of those who bathed ≥7 times a week and determining the percentages of individuals who developed depression based on their GDS scores six years later. Multiple logistic regression analysis was performed to determine odds ratios for the association between depression onset and tub bathing. Results: For individuals who tub bathed ≥7 times a week, the odds ratios for depression onset versus individuals who bathed 0-6 times a week in summer and winter were 0.84 (95% confidence interval, 0.64-1.10) and 0.76 (95% confidence interval, 0.59-0.98), respectively. Tub bathing ≥7 times a week in winter significantly reduced the risk of depression onset. Conclusions: New-onset depression was shown to be infrequent in older adults who bathe in a tub frequently. Tub bathing was suggested to potentially contribute to the prevention of depression in the elderly.
ABSTRACT
Background: Aging affects thermoregulation and can potentially cause cardiovascular changes during bathing in the elderly, possibly leading to accidents and, in worst cases, drowning. However, adequate data on this subject are lacking. Therefore, the purpose of this study was to clarify the effect of aging on thermoregulatory and cardiovascular changes during bathing in the older versus younger adults the relationship between body temperature and thermoregulatory and cardiovascular changes. Methods: Ten young (mean age: 20.4 years) and 10 elderly (mean age: 69.7 years) participants were asked to bathe for 15 min using water at 41°C. Tympanic temperature (Tty), skin blood flow (SkBF), sweating rate (SR), blood pressure, heart rate (HR), and double product (DP) were measured. In addition, we measured subjective psychological changes during bathing. Results: The results showed significant changes in SkBF, SR, and HR in the young participants rather than in the elderly participants. However, in the elderly participants, significant change was noted in systolic blood pressure (SBP). Conclusion: These results demonstrate changes in thermal adaptation and SBP owing to structural and functional progression due to aging.
ABSTRACT
Abstract Background There is an increasing use of daily chlorhexidine gluconate (CHG) bathing to decrease healthcare associated infections (HAI). Daily bathing of patients with CHG has been successfully used to prevent multidrug-resistant organisms (MDROs) HAI in intensive care units (ICU). Methods This was a 12-month, single-center, open, cluster randomized trial, conducted at four ICUs of the University Hospital of Universidade Federal de São Paulo, Unifesp, Brazil. ICUs were randomized to either perform daily bathing of the patients with pH neutral soap and water - control units, or daily bathing with 2% CHG detergent solution - intervention units. We evaluated the incidence density rate of central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), catheter associated urinary tract infection (CAUTI), Klebsiella pneumoniae carbapenemase (KPC)-producing enterobacteria HAI, and death in the intervention and control units. Results A total of 1,640 admissions of 1,487 patients occurred during the study period (41.2% control group, and 58.8% intervention group). Incidence density rates of KPC-producing enterobacteria HAI were 5.01 and 2.25 infections/1000 patient-days in the control units and in the intervention units (p = 0.013) and mortality rates were 28.7% and 18.7% in the control units and in the intervention units (p<0.001), respectively. No difference between groups was observed in CLABSI incidence (p = 0.125), VAP incidence (p = 0.247) and CAUTI incidence (p = 0.435). No serious skin reactions were noted in either study group. Daily 2% CHG detergent solution bathing is a feasible, low cost option for HAI prevention in ICU.

ABSTRACT
Resumen INTRODUCCIÓN : La radiación ultravioleta solar puede resultar perjudicial para la salud y provocar desde quemaduras hasta enfermedades como el cáncer, por ello, el cuidado frente a la alta radiación solar es importante. OBJETIVOS : El objetivo general del presente estudio fue determinar si existe asociación entre los conocimientos y las prácticas sobre foto protecciónen los bañistas peruanos. MATERIALES Y MÉTODOS : Se realizó un estudio trasversal analítico con 380 bañistas peruanos en ocho playas de Lima. Los participantes respondieron un cuestionario donde se recopiló información de los conocimientos y las prácticas de foto protección. Los conocimientos se categorizaron en altos y bajos, y las prácticas en adecuadas e inadecuadas. Para el análisis se empleó la prueba de Chi cuadrado de Pearson y el modelo de regresión de Poisson ajustado por la edad, sexo, nivel educativo y estado civil. RESULTADOS : Se encontró que la práctica de protección adecuada más frecuente fue el uso de foto protector(63%) y la menos frecuente fue el uso adecuado de manga larga y pantalón largo (9,7%). También se evidenció una relación entre los conocimientos altos y tres prácticas fundamentales: uso de foto protector, sombrilla y lentes de sol. CONCLUSIONES : En la muestra de bañistas peruanos, los participantes reportaronde manera general prácticas de foto proteccióndeficientes; además, el poseer conocimientos acerca de la protección solar no aseguró una práctica adecuada de todas las medidas de foto protección.
Abstract INTRODUCTION : Ultraviolet rays can have damaging health effects and cause from sunburn all the way up to diseases such as cancer. Thus, precautionary measures against intense solar radiation are important. OBJECTIVES: The overall objective of this study was to determine whether there is an association between photoprotection knowledge and practices in Peruvianbeach-goers. MATERIALS AND METHODS : An analytical cross-sectional study comparing survey and observational data obtained from 380 Peruvians at eight beaches in Lima was conducted. The participants answered a questionnaire where knowledge was categorized into high and low, and reported practices were dichotomized as appropriate and inappropriate. For variable analysis, Chi square test of Pearson and Poisson regression model adjusted for age, sex, education level and marital status were used. RESULTS : It was found that the most common reported appropriate practice of photoprotection was the use of sunscreen (63%) and the least frequent was the appropriate use of a long sleeve t-shirt and long pants (9.7%). It was also evident that there is a significant relationship between high knowledge and three core practices, including use of sunscreen, beach umbrellas and sunglasses. CONCLUSIONS : In this sample of Peruvian beach-goers, participants generally reported poor photoprotection practices; furthermore, knowledge about sun protection did not assure the practice of all photoprotection measures.
ABSTRACT
Background: This study aimed to clarify the effects of bathing on cardiovascular and psychological responses during winter and summer, focusing on three different time points (immediately after entering the bathtub, during bathing, and immediately after leaving the bathtub). Methods: Ten young (29.6 ± 1.5 years) individuals were asked to bathe for 20 min with 40℃ hot water in summer and with 42℃ hot water in winter. The room temperature and humidity in winter were 20.1℃ and 56.7%, while those in summer were 27.0℃ and 58.3%, respectively. Tympanic temperature (Tty) was measured using a thermistor thermometer; systolic blood pressure (SBP) and diastolic blood pressures (DBP) and heart rate (HR) were measured using an auto-sphygmomanometer, and double product (DP) was calculated using the value of HR multiplied by SBP value. Subjective thermal and comfortable sensations were evaluated using a seven-point rating scale. Results: Results showed a significant increases in SBP values in both seasons immediately after bathing. In winter, DP increased significantly after bathing. Meanwhile, no significant differences were observed in all parameters immediately after bathing between winter and summer. On the contraly, significant differences were observed in Tty, HR, and DP value between winter and summer during bathing. HR and DP values in winter were significantly lower than those in summer immediately after leaving the bathtub. A relationship between thermal sensation and comfortable sensation was observed in both seasons, but the strength of the relationship was more relevant in summer than in winter. Conclusion: The effects of bathing in 42℃ hot water on the cardiovascular system in winter are greater than those in 40℃ hot water in summer. The high temperature of the bath water may not produce as much discomfort during winter than that during summer, therefore bathing time may be longer.
ABSTRACT
Objective To investigate the effect of hot spring baths on human immune function by analyzing the changes of immunoglobulins and complements in serum of residents after hot spring baths in order to provide a theoretical reference for the therapeutic effect of hot spring bathing. Methods After physical examination, 421 volunteers from five hot spring areas with three types of hot springs(temperature type hot springs, metasilicic acid type hot springs, and warm mineral spring type hot springs)in Guizhou Province were selected as the subjects. Under the guidance of professionals, the volunteers took a hot spring bath with the whole body immersed for four weeks, once a day, 5 times a week and 40-50 minutes each time. Finally, 311 volunteers completed the standard bath required by this study. The transmission immunoturbidimetric method was used to determine the content of immunoglobulins reflecting mucosal anti-infective immunity(IgA), anti-pathogenic microorganisms(IgG), recent infections(IgM)and the level of important immune effect factors(C3, C4)in the serum. Paired T test was used to compare the changes of serum immunoglobulin and complement before and after the hot spring bath therapy. Results Before the hot spring baths, the content of serum IgG, IgA, IgM, and complements C3 and C4 was(12.169±2.358)g/L, (2.285±0.891)g/L, (1.430±0.660)g/L, (1.224±0.186)g/L, and(0.257±0.073)g/L, respectively. After the hot spring baths, the content of serum IgG, IgA, IgM, and complements C3 and C4 was(12.769±2.984)g/L, (2.397±0.909)g/L, (1.497±0.715)g/L, (1.242±0.169)g/L, and(0.266±0.074)g/L, respectively.Comparison of results of different types of hot springs showed that warm mineral type of hot springs and metasilicic acid type of hot springs could significantly increase the serum levels of main immunoglobulins IgG and IgA(P < 0.05), while water temperature type of hot springs could increase the serum IgA content of the population(P < 0.05), but the effect on IgG was not significant(P > 0.05). Compared with before the bath intervention, the level of complement C4 in the serum increased in the population after the intervention of metasilicic acid type of hot springs and water temperature type of hot springs(P < 0.05). Conclusion Hot spring bathing can enhance the body's humoral immune function. Given that IgG is the most important anti-pathogenic microorganism antibody in body fluids, the result suggests that metasilicic acid hot spring and warm mineral hot spring are better than pure water temperature hot spring in terms of improving the body's humoral immune function.
ABSTRACT
Objective To understand the influence of hot spring bathing intervention on population's antioxidation functions. Methods Three typical types of hot spring(metasilicic acid type, warm mineral type and temperature type)in Guizhou Province were selected for investigation. According to the inclusion-exclusion criteria, questionnaires and physical examinations results, 421 individuals were selected as observation subjects for hot spring bathing intervention, of which 311 subjects completed 40 to 50 minutes of intervention once a day, 5 days a week, and for 4 weeks. Two physical examinations before and after the intervention were conducted for the 311 subjects. The fasting venous blood samples on the mornings of two physical examinations were collected and the serum was separated. Levels of serum oxidative stress-related parameters including total superoxide dismutase(T-SOD), copper zinc superoxide dismutase(Cu-Zn SOD), glutathione sulfur transferases(GSTs)glutathione peroxidase(GSH-px), sulfhydryl(-SH)and malondialdehyde(MDA)were measured by enzymatical methods. Results The overall comparison showed that compared with before the bathing intervention, the levels of antioxidant enzymes including T-SOD, Cu-Zn SOD, GSTs and GSH-px significantly increased in serum after the intervention(all P < 0.05). There was an increasing trend of serum -SH level after the intervention, but with no statistical differences were seen(P > 0.05). MDA, a product of lipid peroxidation, significantly decreased in serum after the intervention(P < 0.05). The results of classified comparison showed that the effects of different hot spring types on antioxidant enzymes were different. Metasilicic acid type significantly increased the activities of GSTs and GSH-px in serum(all P < 0.05), warm mineral type significantly increased the activities of T-SOD and Cu-Zn SOD in serum(all P < 0.05), and temperature type significantly increased the activities of T-SOD, Cu-Zn SOD and GSTs in serum(all P < 0.05). There were increasing trends of serum -SH levels after bathing intervention of all three hot spring types, but no statistical differences were seen(all P > 0.05). The serum MDA levels decreased significantly after bathing intervention of all three types of hot springs(all P < 0.05). Conclusion Overall, bathing intervention of hot springs can improve the activities of antioxidant enzymes and reduce lipid peroxidation products in population. The results of oxidative stress parameters are slightly different in different types of hot springs. The subjects mainly show the elevation of glutathione related enzyme(GSTs and GSH-px)activities after intervention of metasilicic acid type, the elevation of superoxide dismutase(SOD)activities after intervention of warm mineral type and temperature type, and the decline of lipid peroxidation levels after intervention of all three types. It suggests that hot spring bathing may have certain effects on improving the body's antioxidation functions.
ABSTRACT
Objective To analyze the changes of major and trace elements in urine before and after hot spring bathing, and to explore the effect of hot spring bathing on element metabolism, so as to provide theoretical reference for the physiotherapeutic efficacy of hot spring bathing. Methods The content of Ca, K, Mg, Na, P, S, Sr, Zn, B, Mn, Ni, V, Se, Co, Cr, Cu, Fe, Mo, As, Cd, Hg, Li, Pb and Al in warm mineral springs, metasilicic springs and mineral springs in Guizhou Province was determined by ICP-MS. On the basis of physical examination, 421 people in hot spring areas of Guizhou Province were selected as the subjects. Under the guidance of professionals, the volunteers took a hot spring bath with the whole body immersed for four weeks, once a day, five times a week, for 40-50 minutes each time. Finally, 311 volunteers completed the standard bath required by this study. The content of major elements(Ca, K, Mg, Na, P, and S), essential trace elements(Co, Cr, Cu, Fe, Mo, Se, Sr, and Zn), possibly essential trace elements(B, Mn, Ni, and V)and potentially toxic elements(Al, As, Cd, Hg, Li, and Pb)in urine was analyzed by ICP-MS. Wilcoxon test was used to compare the differences of various elements in urine before and after bathing. Results The water of the warm mineral spring pool mainly contained Mo, Sr, Zn, B, Al, and Pb. The metasilicic acid water mainly contained Cu, V, and As. The water of the mineral spring bubble pool mainly contained Ca, K, Mg, S, Cr, Fe, Se, Mn, Ni, and Li. Compared with before intervention, the content of major elements(Ca, K, Mg, S), essential trace elements(Co, Cr, Cu, Fe, Mo, Se, Zn)and possibly essential trace elements(B, Mn, Ni, V)significantly increased, and the content of potential toxic elements(Al, Li, Pb)significantly decreased after intervention(all P < 0.05). The results showed that the content of P, S, Co, Cr, Mo, Se, Zn, Mn and Ni increased significantly and the content of Hg decreased significantly after metasilicic acid hot spring bathing compared with that before bathing(all P < 0.05). After warm mineral hot spring bathing, the content of Ca, Mg, S and Zn increased significantly, while the content of Al and Pb decreased significantly(all P < 0.05). The content of Mg, S, Co, Cr, Se and Ni increased significantly and the content of Al decreased significantly(all P < 0.05). Conclusion There are many kinds of mineral elements in hot springs in Guizhou Province. After hot spring bathing, the essential trace elements and possible essential trace elements in human body increased, and the potential toxic elements decreased, but there was no gender difference.
ABSTRACT
Objective To observe the intervention effect of typical hot spring bathing in Guizhou province on joint pain, serum anti-keratin antibody(AKA), anti-perinuclear factor antibody(APF)and anti-cyclic citrullinated peptide antibody(CCP). Methods A total of 160 people with joint pain symptoms from five typical hot spring areas in Guizhou province were selected as the subjects. They were treated with hot spring bathing intervention for 4 weeks, once a day, 5 times a week, 40 to 50 minutes each time. According to the evaluation index of physiotherapy natural mineral water in the Code for Geological Exploration and Evaluation of Natural Warm Mineral Water Resources(GB/T 13727-2016)and geological types, the five typical hot springs were divided into three different types, namely water temperature type hot springs(water temperature > 36 ℃), metasilicate type hot springs(metasilicate > 50 mg/L)and warm mineral spring type hot springs(total dissolved solids > 1 000 mg/L). WHO pain grading standard was used to score the degree of joint pain before and after hot spring bathing intervention. Serum APF, AKA and CCP antibodies were detected by ELISA kit before and after hot spring bathing. Results The joint pain score of the subjects was 2.60±0.60, and the joint pain score of the total population decreased after intervention(0.61±0.57, P < 0.05). Before intervention, the joint pain scores of water temperature type, metasilicic acid type and warm mineral spring type were 2.78±0.96, 1.98±1.15 and 3.31±0.57, respectively. After intervention, the scores of joint pain of the three kinds of hot spring bathing patients all decreased(P < 0.05), and were 0.50±0.65, 0.48±0.74 and 0.85±0.90, respectively. Before intervention, AKA(ng/L)and CCP(μg/mL)antibody levels of the observed subjects were 34.89±16.06 and 107.58±10.40, respectively, which significantly decreased after intervention(both P < 0.05), namely 26.06±10.68 and 102.93±6.01, respectively. AKA(ng/L)was 35.04±20.01 before intervention, but decreased significantly after intervention(26.61±7.54, P < 0.05). AKA(ng/L)and CCP(μg/mL)were 31.09±17.26 and 106.51±10.13 before intervention, respectively. After intervention, the above two antibody indexes significantly decreased(all P < 0.05)to 24.53±13.98 and 98.57±5.68, respectively. Before intervention, the AKA(ng/L), APF(ng/mL)and CCP(μg/mL)antibody levels were 38.40±8.66, 349.46±118.43 and 104.96±9.66, respectively. After intervention, the above three antibody indexes significantly decreased(all P < 0.05). The values were 34.00±7.55, 269.38±127.55 and 101.65±3.04, respectively. Conclusion The typical hot spring bathing intervention in Guizhou province can relieve the symptoms of joint pain, and the three types of hot springs can reduce the levels of AKA, APF and CCP antibodies to different degrees, and the warm mineral spring type of hot spring is better than the other types of hot spring.
ABSTRACT
Objective To investigate the prevalence of osteoarthrosis and the association between hot spring bathing and osteoarthrosis among local adults in typical hot spring areas of Guizhou Province. Methods A face-to-face questionnaire survey was conducted among residents aged from 30 to 65 in five typical hot spring areas, including Xifeng(Xifeng County, Guiyang), Jianhe(Jianhe County, Qiandongnan), Fodingshan(Shiqian County, Tongren), Guiyu(Wudang District, Guiyang)and Huishangu(Suiyang County, Zunyi). Residents' basic information, bone and joint diseases prevalence, hot spring bathing, and other health-related behaviors were investigated in this study. The prevalence of local bone and joint diseases was analyzed, and binary logistic regression was used to calculate OR(95%CI)to analyze the association between hot spring bathing and bone and joint diseases. Results A total of 3 708 adults(1 648 males and 2 060 females)were included as the statistical analysis survey subjects, and 794 people reported bone and joint diseases, accounting for a prevalence rate of 21.41%, 95% CI: 0.201-0.227. The prevalence of females(24.56%)was higher than that of males(17.48%)(P < 0.001). The prevalence rates of diseases increased with age(χtrend2=130.265, P < 0.001). There were also statistically significant differences in the prevalence rate of bone and joint diseases among different genders, age groups, occupations, education levels, and smoking behaviors(P < 0.05). After gender, age, occupation, education and smoking were adjusted for, compared with the group who never took hot spring baths, participants who took hot spring baths occasionally(OR=0.793, 95%CI: 0.631-0.996)and frequently(OR=0.713, 95%CI: 0.536-0.948)were associated with a lower risk of bone and joint diseases. Conclusion The prevalence of osteoarthrosis is 21.41% in the typical hot spring areas of Guizhou Province. Older or females have a higher risk of prevalence of bone and joint diseases. Hot spring bathing may be associated with a lower risk of bone and joint diseases.
ABSTRACT
Objective To study the relieving effects of hot spring bath therapy on sleep quality for people with sleep disorders based on data from health bracelets. Methods After health examinations, 311 people with sleep disorders who participated in the bath therapy in five typical hot spring areas in Guizhou Province were selected as the subjects. A four-week hot spring bath therapy was implemented, and the bathing method and the classification of hot springs were the same as the"Overview of study of the physiotherapy efficacy of typical hot springs in Guizhou Province". The daily sleep time at night(minutes), deep sleep ratio(%), light sleep ratio(%)and rapid eye movement ratio(%)for all subjects were collected using the Huawei Honor Band 3 health bracelets. Repeated measures analysis of variance was used to compare the differences in sleep quality indicators of each group at night each week. The effect of three different hot spring bath therapies on the improvement of night sleep quality was evaluated by factor analysis. Results Hot spring bath therapy can increase night sleep time and deep sleep ratio, while reducing light sleep ratio. Compared with the first week, the night sleep time in the following three weeks significantly increased(P < 0.05), especially in the fourth week; the deep sleep ratio during the third and fourth weeks was significantly higher than during the first and second weeks(P < 0.05), but the light sleep ratio was lower than during the first and second weeks(P < 0.05). The rapid eye movement ratio did not change significantly throughout the 4 weeks(P > 0.05). Further classified according to the physiotherapy components of geological hot springs, the results showed that the water temperature type of hot springs can increase night sleep time and reduce light sleep ratio; the warm mineral type of hot springs has a certain regulatory effect on increasing night sleep time, deep sleep ratio and reducing light sleep ratio; the metasilicic acid type of hot springs can improve night sleep quality by increasing night sleep time and deep sleep ratio, while reducing light sleep ratio and rapid eye movement ratio. The factor analysis results suggest that the metasilicic acid type of hot springs is better than the water temperature type and warm mineral type of hot springs in improving night sleep quality. Conclusion Hot spring bath therapy can improve the night sleep quality for people with sleep disorders to varying degrees, and the metasilicic acid type of hot springs is relatively better than other types.
ABSTRACT
Objective To investigate the association between hot spring bathing behavior and hypertension and understand the mediation effect of sleep quality problems on the association. Methods A cross-sectional survey was conducted among adults aged 30 to 65 living and working around five hot springs in Guizhou Province, employing a self-designed questionnaire on the health status and hot spring bathing, and 3 708 qualified questionnaires were collected. Participants were divided into three groups according to their frequency of hot spring bathing: never, occasionally, and frequently. Stratified via sex and sleep quality, the binary logistic regression model was used to analyze the association between different hot spring bathing frequencies and self-reported hypertension. Results Significant difference was detected in the self-reported hypertension between groups who never bathe(13.7%), who occasional bathe(9.4%)and who frequently bathe(8.5%)among female participants(χ2=10.460, P=0.005). However, no significant difference was found among different bathing groups in males. Furthermore, multivariate analysis showed that compared with no bathing, occasional(OR=0.692)and frequent (OR=0.594)hot spring bathing were associated with lower hypertension prevalence among female population, and female groups of occasional and frequent bathing with sleep quality problems had smaller OR(OR=0.571 and 0.406, respectively). After sleep quality problems were included, hot spring bathing was still associated with lower hypertension risk, and the OR values of occasional bathing and frequent bathing groups were 0.723 and 0.611, respectively. The sleep quality problems of female population played a partial mediating role in the association between hot spring bathing and hypertension, and the relative mediating effects of occasional bathing and frequent bathing with hypertension were both statistically significant(Zm=-2.022 and -1.995, P < 0.05), which accounted for 34.34% and 30.15% of the total effects, respectively. Conclusion Regular hot spring bathing may play an auxiliary role in the prevention of hypertension, and it may provide a stronger protection for women, and especially those with sleep quality problems. Sleep quality problems may explain part of the association between hot spring bathing and hypertension in female population.
ABSTRACT
Objective To investigate the effects of hot spring baths on blood pressure, resting heart rate, cardiovascular function related indicators and physical signs in population with high-normal blood pressure. Methods Residents of typical hot spring areas in Guizhou Province were included as the subjects. According to the epidemiological survey of the research group and the physical examination results before the intervention, combined with the inclusion and exclusion criteria, a total of 217 people with high normal blood pressure were selected as the observation subjects. The intervention of hot spring baths was carried out for four weeks, once time per day, 5 times per week, for 40-50 minutes each time. After the intervention, the blood pressure, resting heart rate and serum levels of creatine kinase(CK), lactate dehydrogenase(LDH), and α-hydroxybutyrate dehydrogenase(α-HBDH)were detected, and the improvement of cardiovascular related signs(palpitation, dizziness/headache, cough/sputum and night sweats)were clinically examined. SPSS 23.0 software was used for statistical analysis. Results Paired t-test results showed that the systolic blood pressure, diastolic blood pressure and resting heart rate of 217 high normal blood pressure subjects were significantly lower after hot spring baths(P < 0.01). Further analysis revealed that the number of people with high normal blood pressure dropped from 217 to 128 after the hot spring baths. Before the intervention, 95 of the 217 people with high-normal blood pressure had resting heart rates between 80 and 90 beats/min, and 35 of them above 90 beats/min. After the intervention, the resting heart rates of those above people decreased to 68 and 14, respectively. Serum levels of cardiovascular related indicators showed that CK, LDH, and α-HBDH levels in people with high-normal blood pressure decreased to some extent after the intervention, and CK level was significantly lower than that before the intervention(P < 0.05). The results of clinical examination showed that hot spring baths had a significant improvement effect on palpitation, dizziness/headache, cough/expectoration, and night sweats in people with high-normal blood pressure. Conclusion The typical hot spring baths in Guizhou Province can reduce the blood pressure and resting heart rate in population with high-normal blood pressure, and improve the cardiovascular function related indicators and physical signs to a certain extent.
ABSTRACT
Objective To investigate hot spring bathing behavior and chronic disease prevalence of residents aged 30 to 65 in typical hot spring areas of Guizhou Province. Methods Totally 3 708 individuals between 30 and 65 in five typical hot spring areas of Guizhou Province were included in this study. Their hot spring bathing behavior and chronic disease prevalence were recorded. Unconditional logistic regression was used to analyze the association between hot spring bathing and the incidence of chronic diseases. Results 71.3% of the residents in the hot spring areas had bathed in hot springs, with the proportion higher in males than females(χ2=92.856, P < 0.001). 76.3% of people took hot spring baths fewer than or equal to 6 times per year, 30.8% of residents often chose to take hot spring baths in the evening, and 37.6% of the residents took hot spring baths for 21-40 minutes. Bathing was more common in winter. 11.5% and 17.9% of the residents added other substances and used hot spring facilities, and most of them added traditional Chinese medicine and used the sauna. 46.6% and 41.6 % of the residents took hot spring baths to relax and relieve fatigue. The self-reported prevalence rate of chronic diseases was 522.1‰, and the top five single diseases were lumbar intervertebral disc disease(119.7‰), hypertension(118.1‰), urinary calculus(77.7‰), cervical intervertebral disc disease(53.7‰)and osteogenesis(44.5‰). Compared with those who never bathed in hot springs, taking hot spring baths 7-11 times a year was negatively correlated with chronic diseases.(OR=0.551, 95%CI: 0.345-0.879). Conclusion Hot spring bathing is popular in typical hot spring areas of Guizhou Province, but its frequency is not high. The overall prevalence of chronic diseases is relatively high, and the order of most prevalent chronic diseases is different from that in other areas. Proper hot spring bathing is negatively correlated with chronic diseases.

ABSTRACT
RESUMO O estudo teve por objetivo verificar e avaliar a situação sanitária e o uso e qualidade das águas do Igarapé Santa Cruz, no município de Breves, Pará. Para obtenção dos dados, aplicou-se um questionário que abordou o uso das águas e as condições sanitárias dos moradores às margens do igarapé. Também foi realizada a coleta de água para as análises bacteriológica e dos parâmetros físico-químicos, em quatro pontos do igarapé, nos quais foram feitas duas medições para cada parâmetro a ser analisado, sendo uma na baixa-mar e outra na preamar, em agosto de 2017. Foi aplicado o teste de correlação de Pearson entre as variáveis físico-químicas e bacteriológicas, por meio do software Bioestat 5.3. Entre as 257 famílias entrevistadas, 175 (68,09%) utilizavam a água do igarapé para o uso doméstico, 106 (41,24%) afirmaram que a principal atividade de lazer das crianças é a recreação nas águas e 35 (13,62%) famílias despejam seus dejetos fecais direto no local. O valor médio de oxigênio dissolvido foi de 2 mg/L na maré baixa e de 4,1 mg/L na maré alta. Os valores médios do pH encontram-se entre 6,1 na baixa-mar e 7,0 na preamar. As médias de concentração de coliformes detectadas na baixa-mar foram de 101.809 NMP/100 mL para coliformes totais, 47.654 NMP/100 mL para coliformes termotolerantes e 24.970 NMP/100 mL para E. coli. Na preamar as médias foram de 49.639 NMP/ 100 mL para coliformes totais, 19.994 NMP/100 mL para coliformes termotolerantes e 4.462 NMP/100 mL para E. coli. Conclui-se que a população residente no Igarapé Santa Cruz vive em situação de vulnerabilidade e risco à saúde.
ABSTRACT The aim of this study was to verify and evaluate the sanitary situation and the use and quality of the waters of Santa Cruz creek, in the municipality of Breves, Pará. To obtain the data, a questionnaire was applied to the residents of the creeks waterfronts, which addressed the use of water and sanitary conditions. Water collection was also carried out for bacteriological physical-chemical parameters analysis, in four points of the creek, where two measurements were made for each parameter to be analyzed, one at low tide and one at high, in August 2017. The Pearson correlation test was applied between the physical-chemical and bacteriological variables, using the Bioestat 5.3 software. Among the 257 families interviewed, 175 (68.09%) used water from the stream for domestic use, 106 (41.24%) stated that the main leisure activity for children is recreation in the waters of the igarapé and 35 (13.62%) families dump their fecal waste directly into the stream. The mean dissolved oxygen value was 2 mg/L at low tide and 4.1 mg/L at high tide. The mean values for pH are between 6.1 at low tide and 7.0 at high tide. The mean coliform concentration detected at low tide was 101,809 NMP/100 mL for total coliforms, 47,654 NMP/100 mL for thermotolerant coliforms and 24,970 NMP/100 mL for E. coli. High tide the averages were 49,639 NMP/100 mL for total coliforms, 19,994 NMP/100 mL for thermotolerant coliforms and 4,462 NMP/100 mL for E. coli. It was concluded that the population residing near Santa Cruz creek lives in a situation of vulnerability and health risk.
ABSTRACT
Background: This study aimed to clarify the effects of bathing on cardiovascular and psychological responses during winter and summer, focusing on three different time points (immediately after entering the bathtub, during bathing, and immediately after leaving the bathtub). Methods: Ten young (29.6±1.5 years) individuals were asked to bathe for 20 min with 40°C hot water in summer and with 42°C hot water in winter. The room temperature and humidity in winter were 20.1°C and 56.7%, while those in summer were 27.0°C and 58.3%, respectively. Tympanic temperature (Tty) was measured using a thermistor thermometer; systolic blood pressure (SBP) and diastolic blood pressures (DBP) and heart rate (HR) were measured using an auto-sphygmomanometer, and double product (DP) was calculated using the value of HR multiplied by SBP value. Subjective thermal and comfortable sensations were evaluated using a seven-point rating scale. Results: Results showed a significant increases in SBP values in both seasons immediately after bathing. In winter, DP increased significantly after bathing. Meanwhile, no significant differences were observed in all parameters immediately after bathing between winter and summer. On the contraly, significant differences were observed in Tty, HR, and DP value between winter and summer during bathing. HR and DP values in winter were significantly lower than those in summer immediately after leaving the bathtub. A relationship between thermal sensation and comfortable sensation was observed in both seasons, but the strength of the relationship was more relevant in summer than in winter. Conclusion: The effects of bathing in 42°C hot water on the cardiovascular system in winter are greater than those in 40°C hot water in summer. The high temperature of the bath water may not produce as much discomfort during winter than that during summer, therefore bathing time may be longer.
ABSTRACT
The aim in this literature review was (1) to explore the physiologically and psychologically therapeutic benefits of forest bathing on adults suffering from pre-hypertension or hypertension, and (2) to identify the type, duration, and frequency of an effective forest bathing intervention in the management of pre-hypertension and hypertension, so as to provide directions for future interventions or research. The electronic databases PubMed, Cochrane Library, CINAHL, PsyINFO, and the China Academic Journals (CAJ) offered through the Full-text Database (CNKI) were searched for relevant studies published from the inception of the databases to April 2019. Of the 364 articles that were identified, 14 met the criteria for inclusion in this review. The synthesis of the findings in the included studies revealed that forest bathing interventions were effective at reducing blood pressure, lowering pulse rate, increasing the power of heart rate variability (HRV), improving cardiac-pulmonary parameters, and metabolic function, inducing a positive mood, reducing anxiety levels, and improving the quality of life of pre-hypertensive or hypertensive participants. Forest walking and forest therapy programs were the two most effective forest bathing interventions. Studies reported that practicing a single forest walking or forest therapy program can produce short-term physiological and psychological benefits. It is concluded that forest bathing, particularly forest walking and therapy, has physiologically and psychologically relaxing effects on middle-aged and elderly people with pre-hypertension and hypertension.
