Psychophysiological research on stress-induced sleep bruxism in children

我们采用睡前心理任务，对睡眠质量和心率变异性(HRV)进行采样，研究交感神经活性升高对睡眠后继和睡眠磨牙症的影响。在清醒状态和睡眠状态下，任务夜的交感神经活动均高于无任务夜。目前的研究经验表明，儿童整夜睡眠质量和应激性睡眠磨牙症可能会受到睡前1小时用明亮灯光进行的一些刺激活动的影响。

We investigated the effect of elevated sympathetic nerve activity on following sleep and sleep bruxism using the psychological tasks just before bedtime with sampling sleep quality and heart rate variability (HRV). Sympathetic nerve activities which evaluated with HRV were higher for the Task night than for the No-task night during both the waking state and the sleeping state. The present study empirically indicated that all-night sleep quality and stress-induced sleep bruxism in children can be affected by some exciting activities with bright lights 1-hour before bedtime.
