title: Comparison of sleep/wake habits of university students with or without a habit of self-awakening.
abstract: Several studies have reported that some people have the ability to awaken from sleep without using external means. This ability is called 'self-awakening'. The present study investigated the sleep/wake habits of university students with or without a habit of self-awakening. Of the 643 university students, 66 students (10.3%) habitually self-awakened in daily life. In comparison with those who did not self-awaken (n = 577, 89.7%), self-awakening students went to bed and woke up approximately 30 min earlier, felt better when they woke up in the morning, and dozed off less in the daytime. Moreover, self-awakening students showed a higher morningness score.
