A real life experiment in Germany on steel workers proved that workers got more and better rest resulting in improved productivity when the early risers were assigned the day shifts and the late owls assigned the late shifts. The work schedule aligned with the internal biological clock resulting in a beneficial situation overall. Seeking to remedy the problem is the Southwest Airlines which allows pilots to choose between morning and evening flight schedules. Countries like Canada are relooking at the school timings of children. Child development experts have renewed the call to delay the school starting hours to ensure that students get sufficient sleep.
At a time when schools are becoming increasingly competitive by offering different curricula with the choice of a wide range of subjects and courses, and a spectrum of co-curricular and sports activities, extending the option of flexible timings based on their chronotype within the ambit of curriculum requirements would certainly go a long way in providing alternate solutions to synchronize with the biological clock. The least that schools can do is formulate school timings after considering the biological and physiological sleep regimen of students.
