MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Chronotypes are a result of how the circadian clock embeds itself into the 24h light-dark cycle, producing earlier and later individuals ("larks and owls") with regards to rhythms in physiology, cognition and behavior, including sleep.
It can be beneficial for health and safety to sync forced wake times (work, school) with individual chronotypes, thereby reducing the misalignment between sleep, circadian rhythms and external demands.
To better inform potential interventions such as tailored work schedules, more information is needed about the prevalence of different chronotypes and how chronotype differs by age and sex.
To the best of our knowledge, this is the first large-scale and nationally representative study of chronotypes in the US.
