title: [The comparison of life habits and diurnal changes in subjective symptoms of fatigue in morning, intermediate and evening in young women].
abstract: This investigation was carried out to understand the mutual differences between morning (Mo.), intermediate (In.) and evening (Ev.) types in life habits and the diurnal change in incidence of subjective symptoms of fatigue. Ninety-nine female students were divided into three groups consisting of Mo., In., and Ev. types according to Horne and Ostberg's morningness-eveningness questionnaire. Also, a study of daily time allotment and a questionnaire survey of subjective symptoms of fatigue on awakening, before breakfast, before lunch, before supper and on retiring was conducted on the same subjects. Proportions of Mo,. In. and Ev. types were 18%, 70% and 12% respectively. The rising and retiring time in Ev. was about one hour later in comparison with Mo. types, and the length of sleep was not significantly different between Mo. and Ev. type. The incidence of subjective symptoms upon awakening was lowest in Mo., and became higher in In., Ev. type in that order, and subjective symptoms were lowest before lunch in Mo., and In. type, and before supper in Ev. Physical condition for muscular and mental work appeared to be best at 8:00-10:00 (Mo.), 11:00-13:00(In.) and 15:00-17:00(Ev.) respectively.
