Relationship of chronotype to sleep pattern in a cohort of college students during work days and vacation days.

To study whether the chronotype is linked with the sleep characteristics among college going students assessed during college days and vacation days, adult female students at undergraduate level were asked to answer the Hindi/English version of the Munich Chronotype Questionnaire (MCTQ), fill a sleep log, and drinking and feeding logs for three weeks covering college and vacation days. Based on chronotype categorization as morning type, intermediate type and evening type, sleep onset and offset times, sleep duration and mid-sleep times for each group were compared, separately for college and vacation days. Results indicate that the sleep duration of the morning types was significantly longer than the evening types, both, during college and vacation days. Similarly, the sleep onset and sleep offset times were significantly earlier in the morning types than the evening type students. During the vacation days, the individuals exhibited longer sleep duration with delayed mid-sleep times. Further there was no significant difference among the chronotypes regarding their feeding and drinking frequency per cent during the college and the vacation days. It is suggested that the students should be made aware of their chronotype, so that they can utilize their time optimally, and develop a schedule more suitable to their natural needs.
