 note = {40022531577, The purpose of this study was to explain the sleep-wake rhythm by focusing on the nighttime sleep ofpremature infants at 4 months of age. The circadian rhythm is, natural, internal process that regulates thesleep-wake cycle and the basis of lifelong autonomous activity. In this method, the activity amount wasmeasured using an actigraph, the sound pressure was measured using a micromini sound type sensor, andthe light was measured using a micromini optical sensor over a period of for 72 hours. As a result, total sleep time tended to be short, but deep sleep accounted for a relatively large amount.
It was found that when the mesor, amplitude, and acrophase, which are indicators of sleep-wake rhythm formation, were synchronizeded with the 24-hour rhythm and adjusted to the environment, there were large individual differences. Therefore, in order to support longterm development of sleep-wake rhythms, it is necessary to create a family support program that regulates daily life rhythms at home.},
