Design outcomes

Primary

Measure	Time frame
standard partial regression coefficients of both homeostatic sleep function and circadian rhythms on sleep onset timing	—

Secondary

Measure	Time frame
Sleep parameters (total sleep time, total time of each sleep stage, sleep latency, number of awakening, wake time after sleep onset, number of sleep stage transitions, number of sleep cycles, EEG power spectrum density) Subjective sleepiness Subjective sleep quality Correlation of sleep homeostasis function and circadian rhythm function with age Phase angle between melatonin onset time and sleep time Relationship between sleepiness and thermoregulatory changes in each age Habitual sleep parameters	—
