Effects of light intensity and sleep stages on heart rate variability (HRV) were investigated in young healthy subjects. The low-frequency (LF)/high-frequency (HF) ratio was significantly increased by exposing either to bright lights of 10 000 lx or to extreme darkness (< 0.01 lx), while HF and LF components of HRV were not changed, when compared with those under dim light (100 lx). However, LF was significantly increased at REM sleep, when compared with that at the pre-sleep wake. In contrast, HF was increased at all stages of sleep, and the LF/HF ratio was decreased at slow wave sleep during the baseline night.
在年轻健康受试者中研究了光照强度和睡眠阶段对心率变异性（HRV）的影响。与昏暗灯光（100勒克斯）下相比，暴露于10000勒克斯的强光或极度黑暗（<0.01勒克斯）环境中时，低频（LF）/高频（HF）比值显著增加，而HRV的HF和LF成分未发生变化。然而，与睡前清醒时相比，快速眼动睡眠期LF显著增加。相反，睡眠各阶段HF均增加，且在基线夜间的慢波睡眠期LF/HF比值降低。
