Research Abstract	The purpose of this study was to clarify the relationship between lifestyle and biological rhythm in preschool-aged children. We conducted a longitudinal survey from 2007 to 2009. The result of this survey revealed that the children were going to bed and waking up approximately 30 minutes earlier than current reports. Wake-up time was significantly later in winter than in summer. The result of this survey revealed that the temperature rhythm was stable in approximately 50% of the children. We found that bedtime, wake-up time, and age in months were associated with temperature rhythm. The longitudinal survey revealed that both short- and long-term lifestyle factors exerted a strong influence on temperature rhythm at all time point.
