Fig. 1From: Circadian phase advances in children during camping life according to the natural light-dark cycleOverview of the experimental protocol with data obtained by actigraphy. Data obtained in 2017 for a participant’s activity and light exposure measured by a wrist activity monitor with a light sensor (MotionWatch 8). Black ticks denote activity and yellow ticks denote light exposure. The vertical axis shows the number of days in the camping program session and the horizontal axis shows the time of day. PreCamp-DLMO assessment was performed on the first day of the camping program both in the earlier wake time (EW) condition and the synchronized wake time (SW) condition. Camp-DLMO assessment was performed on the 11th day of the camping program in the EW condition and on the 14th day of the camping program in the SW conditionBack to article page
