Abstract
To clarify the effect of cold stimulation during slow-wave sleep (SWS) on the sleep cycle, we conducted a sleep experiment. Five healthy males slept on a bedding system we developed to make the inside of bedding cooler. When the subject was sleeping deeply in the second and fourth SWS, the system cooled their bedding. When the subject's sleep condition shifted toward arousal, the cold air was stopped. As a result, all subjects' sleep stage shifted to light sleep and reached arousal. After stopping stimulation, they immediately returned to the SWS at the first stimulation. But at the second stimulation, the sleep state did not return to the SWS.
