OBJECTIVE: We aim to verify the effectiveness of mindful breathing exercises using a tablet device.
METHODS: In total, 18 nursing students, aged 18-22 years, were randomly assigned and divided equally into mindfulness (Mi) and nonmindfulness (nMi) implementation groups using tablet devices. During the 9-day experimental period, cardiac potentials were measured on days 1, 5, and 9. In each sleep stage (sleep with sympathetic nerve dominance, shallow sleep with parasympathetic nerve dominance, and deep sleep with parasympathetic nerve dominance), low frequency (LF) value, high frequency (HF) value, and LF/HF ratios obtained from the cardiac potentials were evaluated.
RESULTS: On day 5, a significant correlation was observed between sleep duration and each sleep stage in both groups. In comparison to each experimental day, the LF and LF/HF ratios of the Mi group were significantly higher on day 1 than on days 5 and 10. LF and HF values in the nMi group were significantly higher on day 1 than on day 5.
CONCLUSIONS: The correlation between sleep duration and each sleep stage on day 5 suggested that sleep homeostasis in both groups was activated on day 5, resulting in similar changes in sleep stages. During the experimental period, the cardiac potentials in the nMi group showed a wide range of fluctuations, whereas the LF values and LF/HF ratio in the Mi group showed a decreasing trend over time. This finding suggests that implementing mindful breathing exercises using a tablet device may suppress sympathetic activity during sleep.

目的:我们旨在验证使用平板设备进行正念呼吸练习的有效性。
方法:总共,18名护理学生,18-22岁,被随机分配,并使用平板设备平均分为正念(Mi)和非正念(nMi)实施组。在为期9天的实验期间,在第1,5和9天测量心脏电位.在每个睡眠阶段(交感神经优势睡眠,浅睡眠与副交感神经优势,和具有副交感神经优势的深度睡眠),低频(LF)值,高频(HF)值,评估从心脏电位获得的LF/HF比率。
结果:在第5天,两组的睡眠持续时间与每个睡眠阶段之间均观察到显着相关性。与每个实验日相比,Mi组的LF和LF/HF比率在第1天明显高于第5天和第10天。nMi组的LF和HF值在第1天明显高于第5天。
结论:第5天的睡眠持续时间与每个睡眠阶段之间的相关性表明,两组的睡眠稳态在第5天都被激活,导致睡眠阶段的相似变化。在实验期间,nMi组的心脏电位显示出广泛的波动,而Mi组的LF值和LF/HF比值随时间呈下降趋势。这一发现表明,使用平板设备实施正念呼吸练习可以抑制睡眠期间的交感神经活动。
