Social Jetlag- An Exhausting Condition in 21^st Century – A Conceptual Framework

Our lives are regulated by three types of clocks: the social clock, which schedules our interactions with others (local time); the biological clock, which manages our body’s functions (circadian time); and the solar clock, which dictates natural light and darkness. When these clocks are out of sync, our risk of developing certain diseases increases. The term ’social jetlag’ measures the disparity between local time and circadian time.
