Methods: A total of 20 midwives and public health nurses were selected as participants. Teaching materials and anonymous self-administered questionnaires were distributed, and the participants were asked to view the teaching materials and fill in the questionnaires. Retrieval was done by mail. The teaching materials included digital content, such as videos, sounds, and characters, which incorporated dangerous situations, preventions, and innovations in ablution and bathing procedures. The analysis was conducted by simple tabulation for each survey item. The free description was coded to preserve anonymity. This study was conducted with the approval of the Research Ethics Review Board of the authors’ affiliated university. Results: The teaching materials were found to be appropriate in terms of suitability to purpose, degree of difficulty of content, ease of viewing the videos, validity of time, appropriateness of expression, and usability. Conclusions: Ablution teaching materials that are used at the present time do not focus on dangers, and to date, no resources on bathing have been used as teaching materials. The created teaching materials in this study can be viewed multiple times, and mothers and family members who are unfamiliar with ablution and bathing can acquire knowledge regarding dangers and danger prevention. The addition of specific preventive measures and countermeasures for the occurrence of danger, along with practice, would result in the development of further appropriate teaching materials to reduce danger and alleviate anxiety.展开更多

Methods Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10. One group was sent on a two-night trip to a broad-leaved evergreen forest, and the other was sent to a city area. Serum cytokine levels reflecting inflammatory and stress response, indicators reflecting oxidative stress, the distribution of leukocyte subsets, and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments. A profile of mood states (POMS) evaluation was used to assess changes in mood states. Results No significant differences in the baseline values of the indicators were observed between the two groups before the experiment. Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level, as evidenced by decreased malondialdehyde, interleukin-6, and tumor necrosis factor a levels compared with the urban group. Serum cortisol levels were also lower than in the urban group. Notably, the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment. The POMS evaluation showed that after exposure to the forest environment, subjects had lower scores in the negative subscales, and the score for vigor was increased. Conclusion Forest bathing is beneficial to human health, perhaps through preventive effects related to several pathological factors.展开更多

We had earlier demonstrated that a 4-day forest bathing trip can provide an adjunctive therapeutic influence on patients with CHF. To further investigate the duration of the impact and the optimal frequency of forest bathing trips in patients with CHF, we recruited those subjects who had experienced the first forest bathing trip again after 4 weeks and randomly categorized them into two groups, namely, the urban control group (city) and the forest bathing group (forest). After a second 4-day forest bathing trip, we observed a steady decline in the brain natriuretic peptide levels, a biomarker of heart failure, and an attenuated inflammatory response as well as oxidative stress. Thus, this exploratory study demonstrated the additive benefits of twice forest bathing trips in elderly patients with CHF, which could further pave the way for analyzing the effects of such interventions in CVDs.展开更多

This study investigated the chronic mental health effects of BB, maintaining warmth using an insulating sheet and sleeping bag after bathtub bathing (BBW), and bathtub bathing with herbal extracts (BBH) in healthy young adults. The study involved healthy young adults who habitually showered, as opposed to bathing. In the first experiment, 18 participants were randomly assigned to either the BB or BBW groups for 14 consecutive nights. After a 2-week washout period, the participants were asked to switch their bathing styles (a cross-over design). In the second experiment, 20 participants were randomly assigned to the BB or BBH group. The herbal extracts for the BBH group contained angelicae radix, aurantii nobilis pericarpium, chamomile, and zingiberis rhizoma. After a 2-week washout period, these participants also switched to the other bathing style. The participants’ mental conditions pre- and post-intervention were assessed using the Profile of Mood States-Brief Form questionnaire, Japanese version, and were statistically analyzed. The participants’ Anger-Hostility score converged to an average (50 points) in the post-BBW and post-BBH participants, and there were no significant differences in BB. The Confusion change rate was significantly different in the first experiment (BB versus BBW). The Depression-Dejection and Fatigue change rates were significantly different in the second experiment (BB versus BBH). Our findings suggest that changing bathing style from showering to BBW or BBH improves the POMS Anger-Hostility scores of healthy young adults.展开更多

The predominant causes of death in such cases are cardiovascular events and drowning. Blood pressure changes induced by water pressure and high temperature during bathing may be an important cause of these accidents. Therefore, we investigated the changes in blood pressure, heart rate, and oxygen saturation (SpO2) before and after bathing in elderly Japanese individuals. Methods: Forty-eight elderly (average age, 86.4 ± 7.5 years) persons were enrolled in this study. Results: Changes in systolic blood pressure after bathing correlated negatively with baseline blood pressure before bathing, and participants with baseline systolic blood pressures of <125 mmHg experienced a greater elevation in blood pressure while bathing. Pulse rate was significantly increased after bathing, and the change in pulse rate correlated negatively with the baseline values. SpO2 did not differ significantly during bathing, but changes in SpO2 correlated negatively with baseline values. Lean participants showed a more marked elevation of SpO2, and those with hypertension showed reduced SpO2. Conclusion: These data suggest that the disabled elderly with low blood pressure experience trends in cardiovascular response during bathing which differ from those of young persons.展开更多

Using healthy volunteers, we assessed body temperature (core and cutaneous), red blood cells, white blood cells (WBCs), venous blood gas parameters (PO2, SO2, PCO2, TCO2, HCO3, and pH), weight loss (which may indicate sweat volume), and the time until sweating before and after bathing. We simultaneously conducted a double-blind clinical trial using a bath additive group and a control group to investigate the effect of a bath additive on the same parameters. We found that bathing increased the core and cutaneous body temperature, as well as PO2, SO2, and blood pH. All of the subjects also showed increases in heart rate and weight loss (sweat volume). After bathing, the number and ratio of granulocytes increased while the number and ratio of lymphocytes decreased. These results tended to be emphasized in the bath additive group;however, significant between-group differences were not detected. Our results indicated that bathing improved blood circulation and had a modulatory effect on the autonomic nervous system. This suggested that traditional Japanese style bathing might contribute to good health and longevity;however, additional larger-scale studies were needed to confirm or refute this conclusion.展开更多

Descriptive statistical analysis was performed for each category surveyed. Inferential statistics were used to compare the dangerous incidents experienced with regard to differences between primi/multipara and the presence/absence of guidance concerning such incidents. This study was approved by the research ethics committees of the affiliated university. <strong>Results:</strong> 60.0% of mothers and families experienced dangers while washing their infant in a baby tub or similar apparatus (ablution), and 64.9% did while bathing their infant in the normal bath. For ablution, the most common dangers were, in order, nearly dropping the infant in the water and nearly getting soap suds in the mouth. For bathing, these were nearly getting soap suds in the mouth, near submersion of the face, and nearly dropping the infant in the water. The percentage of mothers and families who did not receive instruction regarding potential dangers and their prevention was 55.9% for ablution and 81.8% for bathing. <strong>Conclusion:</strong> This study revealed the dangers experienced by mothers and families of infants aged 3 - 4 months in Japan during ablution and bathing. Further consideration into the prevention of these dangers is necessary.展开更多

As a secondary objective, differences in skin surface temperature and subjective comfort for hot towel application on the back and dry towel wiping alone were evaluated. For the first objective, hot towels were applied on the lower back of 20 healthy adults, for different duration (10, 15, and 20 s), with a 10-s duration found to be the most effective. For the second objective, we compared bed bathing with hot towel application to dry wiping alone, n 21 healthy adult participants. A 10-s hot towel application increased the surface temperature of the skin (+0.5℃) and provided a perceived sensation of warmth and comfort. In contrast, dry wiping significantly decreased the surface skin temperature (-0.8℃). In conclusion, hot towel application increased skin surface temperature and improved subjective warmth and comfort during bed bathing.展开更多

We obtain a general solution and analyze the asymptotic quantum states. We find that most of these asymptotic states can be genuinely entangled depending upon the parameters of the channel, memory parameter, and the parameters of the initial states. We study Greenberger–Horne–Zeilinger(GHZ) states and W states, mixed with white noise,and determine the conditions for them to be genuinely entangled at infinity. We find that for these mixtures, it is possible to start with a bi-separable state(with a specific mixture of white noise) and end with genuine entangled states. However, the memory parameter μ must be very high. We find that in contrast to the two-qubit case, none of the three-qubit asymptotic states for n → ∞ are genuinely entangled.展开更多

Besides its linear coupling with a harmonic bath modelling the dissipation, we suppose that it is coupled with an oscillator with an interaction of the form s 2 x 2 . In our study, we integrate over the bath and the oscillator, extract the corresponding influence functionals and then solve the system’s sign problem. We apply the theory to the case of a double well and study the time evolution of the expectation value of the position.展开更多

文摘Frequent bathtub bathing (BB) improves the mental health of middle-aged and older Japanese in-dividuals. This study investigated the chronic mental health effects of BB, maintaining warmth using an insulating sheet and sleeping bag after bathtub bathing (BBW), and bathtub bathing with herbal extracts (BBH) in healthy young adults. The study involved healthy young adults who habitually showered, as opposed to bathing. In the first experiment, 18 participants were randomly assigned to either the BB or BBW groups for 14 consecutive nights. After a 2-week washout period, the participants were asked to switch their bathing styles (a cross-over design).

The herbal extracts for the BBH group contained angelicae radix, aurantii nobilis pericarpium, chamomile, and zingiberis rhizoma. After a 2-week washout period, these participants also switched to the other bathing style. The participants’ mental conditions pre- and post-intervention were assessed using the Profile of Mood States-Brief Form questionnaire, Japanese version, and were statistically analyzed. The participants’ Anger-Hostility score converged to an average (50 points) in the post-BBW and post-BBH participants, and there were no significant differences in BB. The Confusion change rate was significantly different in the first experiment (BB versus BBW). The Depression-Dejection and Fatigue change rates were significantly different in the second experiment (BB versus BBH). Our findings suggest that changing bathing style from showering to BBW or BBH improves the POMS Anger-Hostility scores of healthy young adults.
文摘Aims: Bathing in deep, Japanese-style bathtubs is associated with high rates of sudden death in the elderly in Japan. The predominant causes of death in such cases are cardiovascular events and drowning. Blood pressure changes induced by water pressure and high temperature during bathing may be an important cause of these accidents. Therefore, we investigated the changes in blood pressure, heart rate, and oxygen saturation (SpO2) before and after bathing in elderly Japanese individuals. Methods: Forty-eight elderly (average age, 86.4 ± 7.5 years) persons were enrolled in this study. Results: Changes in systolic blood pressure after bathing correlated negatively with baseline blood pressure before bathing, and participants with baseline systolic blood pressures of <125 mmHg experienced a greater elevation in blood pressure while bathing. Pulse rate was significantly increased after bathing, and the change in pulse rate correlated negatively with the baseline values. SpO2 did not differ significantly during bathing, but changes in SpO2 correlated negatively with baseline values. Lean participants showed a more marked elevation of SpO2, and those with hypertension showed reduced SpO2. Conclusion: These data suggest that the disabled elderly with low blood pressure experience trends in cardiovascular response during bathing which differ from those of young persons.
文摘The objective of this study was to determine how traditional Japanese style bathing could promote good health. Using healthy volunteers, we assessed body temperature (core and cutaneous), red blood cells, white blood cells (WBCs), venous blood gas parameters (PO2, SO2, PCO2, TCO2, HCO3, and pH), weight loss (which may indicate sweat volume), and the time until sweating before and after bathing. We simultaneously conducted a double-blind clinical trial using a bath additive group and a control group to investigate the effect of a bath additive on the same parameters. We found that bathing increased the core and cutaneous body temperature, as well as PO2, SO2, and blood pH. All of the subjects also showed increases in heart rate and weight loss (sweat volume).

文摘The purpose of this study was to determine the most effective duration of hot towel application during bed bathing, based on temporal changes in skin surface temperature, towel temperature, and subjective comfort. As a secondary objective, differences in skin surface temperature and subjective comfort for hot towel application on the back and dry towel wiping alone were evaluated. For the first objective, hot towels were applied on the lower back of 20 healthy adults, for different duration (10, 15, and 20 s), with a 10-s duration found to be the most effective. For the second objective, we compared bed bathing with hot towel application to dry wiping alone, n 21 healthy adult participants. A 10-s hot towel application increased the surface temperature of the skin (+0.5℃) and provided a perceived sensation of warmth and comfort. In contrast, dry wiping significantly decreased the surface skin temperature (-0.8℃). In conclusion, hot towel application increased skin surface temperature and improved subjective warmth and comfort during bed bathing.

文摘Objective:To examine the efficacy and safety of bathing therapy with Taohong Siwu Decoction(桃红四物汤,TSD) in the treatment of early-stage,mild-moderate diffuse cutaneous systemic sclerosis(dc SSc).Methods:This randomized,placebo-controlled trial enrolled 148 men and women(18–60 years) with dc SSc(disease duration 12 months) and baseline modified Rodnan skin score(MRSS) 10.Patients were randomized into a TSD group(71 cases bathing with TSD plus oral prednisone) or control group(71 cases bathing with placebo plus oral prednisone).Bathing(40 ℃,30 min) of the upper and lower limbs was carried out once daily for 12 consecutive weeks.The primary outcome measure was MRSS;secondary outcomes were Raynaud's phenomenon(RP) score,quality of life(QOL),physician visual analogue scale(VAS),patient VAS,percent predicted diffusing capacity for carbon monoxide(DLCO),percent predicted forced vital capacity(FVC),erythrocyte sedimentation rate(ESR),C-reactive protein(CRP) level and overall treatment effect.Results:The final analysis included 135 patients(control group,68 cases;TSD group,67 cases).Primary and secondary outcome measures after 2 weeks of treatment showed no improvement(versus baseline) in both groups,with no differences between groups.At 12 weeks,QOL,physician VAS,patient VAS,ESR and CRP were improved in both groups,but MRSS and RP score were improved only in the TSD group(all P〈0.05).MRSS,RP score,QOL,physician VAS,patient VAS,ESR and CRP differed significantly between groups(all P〈0.05).Meanwhile,the overall treatment effect was significantly higher in the TSD group than in the control group(P〈0.05).Adverse events in the two groups were similar(P〉0.05).Conclusions:Bathing with TSD plus oral prednisone achieves better outcomes than oral prednisone alone in patients with dcS Sc and is not associated with serious adverse events.
文摘We study genuine entanglement among three qubits undergoing a noisy process that includes dissipation, squeezing,and decoherence. We obtain a general solution and analyze the asymptotic quantum states. We find that most of these asymptotic states can be genuinely entangled depending upon the parameters of the channel, memory parameter, and the parameters of the initial states. We study Greenberger–Horne–Zeilinger(GHZ) states and W states, mixed with white noise,and determine the conditions for them to be genuinely entangled at infinity. We find that for these mixtures, it is possible to start with a bi-separable state(with a specific mixture of white noise) and end with genuine entangled states. However, the memory parameter μ must be very high. We find that in contrast to the two-qubit case, none of the three-qubit asymptotic states for n → ∞ are genuinely entangled.
文摘We study the dynamics of a quantum dissipative system. Besides its linear coupling with a harmonic bath modelling the dissipation, we suppose that it is coupled with an oscillator with an interaction of the form s 2 x 2 . In our study, we integrate over the bath and the oscillator, extract the corresponding influence functionals and then solve the system’s sign problem. We apply the theory to the case of a double well and study the time evolution of the expectation value of the position.
文摘Bathing is a major type of disability among older adults.While studies on bath-ing difficulties have recently started to go beyond the limitations of the human body to examine bathroom amenities;researchers have rarely considered the environment beyond the bathroom.This study explored the regional disparities in bathing disabil-ity among older adults in China.Using data from the Chinese Longitudinal Healthy Longevity Survey from 1998 to 2018,random-effects logistic regressions were per-formed to examine how bathing difficulties differed across regions among older adults in China.We found that older adults residing in the northern regions were significantly more likely to experience bathing disability compared to those from the South after controlling for confounding variables.Women and the oldest-old were also the most likely to experience bathing disabilities.Within the Northern regions itself,individuals from the Northeast stood out for having the highest likelihood of experiencing bathing disability.Interestingly,this regional disparity only existed for bathing disability and not the other Activities of Daily Living(ADL)items.It is concluded that the large regional disparity could be due to both climate differences and uneven economic development across the different regions in China.As bath-ing is a highly environment-dependent activity,this study highlights the potential for policy interventions to reduce the prevalence of bathing disability among older adults through improving the bathing environment.Additionally,we aim to put forth the notion that disability research should move towards analyses of specific disabil-ity items rather than an undifferentiated ADL index.
