To examine if real-world stress affects the restorative function of sleep in daily life, we studied the impact of college examinations on cardiorespiratory resting function during sleep. In healthy college students, at 1 week before, the day before, and the first day of semester-end examinations pulse wave signal during sleep at their own residences was measured continuously with a wristband-shaped wireless transdermal photoelectric sensor. The cardiorespiratory resting function was assessed quantitatively as the power of a high-frequency component of pulse rate variability, a surrogate measure of respiratory sinus arrhythmia. Changes in anxiety were also evaluated with a state anxiety questionnaire. On the day before the examinations, compared with 1 week before, the score of state anxiety increased and the HF component of pulse rate variability decreased. Among college students, anxiety about college examinations may be accompanied by suppression of the cardiorespiratory resting function during sleep.
为了研究现实生活中的压力是否会影响日常生活中睡眠的恢复功能，我们研究了大学考试对睡眠期间心肺静息功能的影响。在健康的大学生中，在学期末考试前1周、前一天和第一天，使用腕带式无线透皮光电传感器在他们自己家中连续测量睡眠期间的脉搏波信号。心肺静息功能通过脉搏率变异性高频成分的功率进行定量评估，这是呼吸性窦性心律失常的替代指标。还使用状态焦虑问卷评估焦虑的变化。在考试前一天，与前1周相比，状态焦虑得分增加，脉搏率变异性的高频成分降低。在大学生中，对大学考试的焦虑可能伴随着睡眠期间心肺静息功能的抑制。
