This study tested whether the cortisol awakening response is dependent on the transition from sleep to awakening, or alternatively, a circadian-driven process that is independent of awakening. A total of 40 participants were randomly assigned to either a total sleep deprivation or a sleep condition. Salivary cortisol was also assessed. Participants in the sleep condition demonstrated a traditional cortisol awakening response, whereas participants in the total sleep deprivation condition showed no increases in morning cortisol. These results are consistent with the notion that if circadian-driven processes are related to the cortisol awakening response, they may only be activated when awakening occurs or is anticipated.
本研究测试了皮质醇觉醒反应是取决于从睡眠到觉醒的转变，还是相反，是一个独立于觉醒的昼夜节律驱动过程。共有40名参与者被随机分配到完全睡眠剥夺组或睡眠组。同时也对唾液皮质醇进行了评估。睡眠组的参与者表现出传统的皮质醇觉醒反应，而完全睡眠剥夺组的参与者早晨皮质醇没有增加。这些结果与以下观点一致：如果昼夜节律驱动过程与皮质醇觉醒反应有关，那么它们可能只在觉醒发生或被预期时才被激活。
