Three groups of young, normal sleepers were selected as morning types (MTs), evening types (ETs), and neither types (NTs) as determined by the Horne and Ostberg questionnaire. Sleep and rectal temperatures were recorded under three conditions: baseline nights (Cond. 1), sleep on the recovery day after 1 night of sleep deprivation (Cond. 2), and sleep on the recovery night after 1 night and 1 day of sleep deprivation (Cond. 3). During Conds. 1 and 3, when sleep schedules were self-determined, sleep structure and body temperature were similar in MTs, and ETs, and NTs. During Cond. 2, however, MTs had poorer sleep, i.e., a smaller percentage of REM sleep and more awakenings, than ETs. This difference can be related to the evolution of temperature during Cond. 2; i.e., a temperature increase in the MT and NT and a decrease in the ET.
根据霍恩和奥斯特伯格问卷，选取三组年轻的正常睡眠者，分别为早起型（MTs）、晚睡型（ETs）和中间型（NTs）。在三种条件下记录睡眠和直肠温度：基线夜晚（条件1）、睡眠剥夺1晚后的恢复日睡眠（条件2）以及睡眠剥夺1晚和1天后的恢复夜晚睡眠（条件3）。在条件1和条件3期间，当睡眠时间表由自身决定时，早起型、晚睡型和中间型的睡眠结构和体温相似。然而，在条件2期间，早起型的睡眠质量较差，即快速眼动睡眠的百分比更小，觉醒次数更多，比晚睡型差。这种差异可能与条件2期间体温的变化有关；即早起型和中间型体温升高，晚睡型体温下降。
