| Research Abstract |
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.
