Abstract
It is one of the fundamental role of nursing to ensure that a person get adequate high quality sleep. Though the relationship between individual variation in illunminance preference during the hypnagogic stage and the quality of sleep has not been sufficiently clarified, it is essential evidence for environmental coordination during sleep onset.
In this study, the influence of individual variations in illuminance preference during hypnagogic stage on physiological function was analyzed and subjective evaluation tests were performed. Electroencephalogram and heart rate variability were used as indicators of physiological function, and the subjective evaluation was conducted by questionnaire.
Under favored illuminance conditions, deep sleep was achieved at an earlier stage, showed an increase in parasympathetic activity, and subjective evaluation revealed that sleep was easily achieved. In conclusion, the results of our study provided fundamental evidence for environmental coordination at the time of sleep onset.
