Why you should stick to your biological clock Circadian rhythms are not only involved in regulating sleep. Eating behavior, blood pressure, body temperature, metabolic rate, hormone levels, including those responsible for sleep, also fall under the control of the biological clock.
If, say, a lark changes comfortable conditions for him to the opposite - begins to wake up late and fall asleep late -
not only his nervous system, but also all other organs and systems will adjust to the new regime
It is the same with the antipode of the lark, the owl. A person with this chronotype can accustom himself to go to bed and get up early, but the body will still require a natural routine.
As a result, at the slightest loosening, he will return to the former regime.
So, it is better to refuse to work in the day shift, just as a lark - in the night shift.
