RR-interval and eight types of mood level were recorded for 48 h from 40 normal male subjects. Sympathovagal balance was evaluated by calculating the normalized high-frequency power (HFnu) of RR-interval variability. The mean mood levels during 6 h before bedtime and the mean HFnu during 3 h after bedtime were compared. The data were normalized individually and the differences from the first night (Deltamood and DeltaHFnu) were taken. The correlation coefficient between Deltadepression and DeltaHFnu was -0.53, and that between Deltaworry and DeltaHFnu was -0.44. This implies that both daily depression and worry shift toward sympathetic dominance during subsequent sleep.
记录了40名正常男性受试者48小时的RR间期和八种情绪水平。通过计算RR间期变异性的标准化高频功率（HFnu）来评估交感迷走神经平衡。比较了睡前6小时的平均情绪水平和睡后3小时的平均HFnu。数据分别进行标准化，并计算与第一晚的差异（Δ情绪和ΔHFnu）。Δ抑郁与ΔHFnu之间的相关系数为-0.53，Δ担忧与ΔHFnu之间的相关系数为-0.44。这意味着在随后的睡眠中，日常的抑郁和担忧都向交感神经占优势转变。
