Chronotype, or an individual's preferred time of sleep and activity, is one of the major internal cues that helps to harmonise one's biological events according to its circadian timing [1]. Three major variations of chronotype exist among humans, those who prefer to wake up early and sleep early at night (known as morning types or “larks”), those who prefer late sleep at night and late waking up in the morning (referred to as evening type or “owls”) and those who remain in between (intermediate type) [1].Individual preference of sleep and activity (chronotype) might play an important role on asthma and allergic diseases in adolescents: this link underscores a potential plausible behavioural intervention for asthma and allergic diseases in young population https://bit.ly/2THta9IThe authors are grateful to the administrations of the attended schools for allowing to conduct the study, the students for participating in this study and the parents for their consent. Part of the study's results were presented in the 30th Conference of the International Society for Chronobiology, held in Warsaw, Poland, on 2–5 July 2019. ER -
