Health care workers (HCWs) experience abounding physical and mental exhaustion mandating a deliverable solution for their mental health care. Kriya yoga (KY) includes several relaxation techniques and offers a stress-alleviating experience. The objective signature of KY benefits needs to be investigated.
To study the effects of KY practice on brain oscillations and perceived stress in health care providers.
This prospective interventional study was conducted during coronavirus disease 2019 pandemic. HCWs were enrolled to the intervention group (IG) and control group (CG) after obtaining an informed consent. IG visited the yoga center for learning the KY technique. Electroencephalogram (EEG) was recorded in both the groups, at baseline, and at the end of 6 weeks in the EEG Laboratory. Perceived stress scale (PSS) scores and participants' subjective response to KY practice were also collected. Paired -test and independent -test were used for statistical comparison wherever applicable.
Age and baseline EEG powers among the IG and CG (N = 25) were statistically comparable. Absolute power analysis revealed a statistically significant increase in alpha and delta powers after 6 weeks of KY practice. The PSS scores revealed a statistically significant decrease in perceived stress after KY practice. Furthermore, 83% of the participants reported the subjective calming effects of KY practice.
KY practice ensues relaxing effects on the brain, as evident from the EEG absolute power analysis, PSS scores, and participants' subjective response. As KY is a brief technique, it may be encouraged during short break session among the HCWs for promotive health.
医护人员身心疲惫不堪，需要为他们的心理健康提供切实可行的解决方案。克里亚瑜伽（KY）包含多种放松技巧，能带来减轻压力的体验。KY益处的客观特征有待研究。
研究练习KY对医护人员大脑振荡和感知压力的影响。
这项前瞻性干预研究在2019年冠状病毒病大流行期间进行。在获得知情同意后，医护人员被纳入干预组（IG）和对照组（CG）。IG组前往瑜伽中心学习KY技巧。两组均在基线时以及在脑电图实验室6周结束时记录脑电图（EEG）。还收集了感知压力量表（PSS）得分以及参与者对KY练习的主观反应。在适用的情况下，使用配对检验和独立检验进行统计比较。
IG组和CG组（N = 25）的年龄和基线EEG功率在统计学上具有可比性。绝对功率分析显示，KY练习6周后，α和δ功率有统计学意义的增加。PSS得分显示，KY练习后感知压力有统计学意义的降低。此外，83%的参与者报告了KY练习的主观平静效果。
从脑电图绝对功率分析、PSS得分和参与者的主观反应可以明显看出，KY练习对大脑有放松作用。由于KY是一种简短的技巧，在医护人员的短暂休息期间可以鼓励练习以促进健康。
