To determine whether restorative yoga is an effective method for relieving occupational stress among female nurses working the night shift in Japan.
From July 2017 to May 2018, 20 female nurses aged in their 20s to 30s who were working the night shift at a university hospital participated in a randomized crossover trial, consisting of a 1-hour guided group yoga session followed by 4 weeks of at-home practice and 4 weeks of usual stress relief methods. The level of stress was assessed by the Brief Job Stress Questionnaire of the Ministry of Health, Labour and Welfare before and after performing restorative yoga. Descriptive statistics were calculated and data were analyzed by Student's t test, one-way analysis of variance (with repeated measures), or Bonferroni's multiple comparison test.
Vital signs showed no significant differences from before to after the group yoga session, and there was no change of weight after 4 weeks of at-home practice. The mean questionnaire score for "psychological and physical stress reactions" was significantly reduced after the group yoga session. In addition, the mean score was significantly lower after 4 weeks of at-home practice than before or after group yoga, or after 4 weeks of the usual stress relief methods.
These findings suggest that restorative yoga may be effective for alleviating occupational stress among female nurses working the night shift.
探究修复瑜伽是否为一种缓解日本女性夜间倒班护士职业压力的有效方法。
2017 年 7 月至 2018 年 5 月，20 名年龄在 20 多岁至 30 多岁之间、在大学医院上夜班的女性护士参与了一项随机交叉试验，包括 1 小时的小组引导瑜伽课程，以及 4 周的家庭练习和 4 周的常规减压方法。在进行修复瑜伽前后，使用厚生劳动省的《简要工作压力问卷》评估压力水平。计算描述性统计数据，并通过学生 t 检验、单向方差分析（重复测量）或 Bonferroni 多重比较检验进行数据分析。
小组瑜伽课后的生命体征与课前相比无显著差异，家庭练习 4 周后体重无变化。小组瑜伽课后，“心理和生理应激反应”的问卷平均评分显著降低。此外，家庭练习 4 周后的评分明显低于小组瑜伽课前或课后，以及常规减压方法 4 周后。
这些发现表明，修复瑜伽可能有助于缓解夜间倒班的女性护士的职业压力。
