Answer 1

Your biorhythm is determined by the sleep hormones and wakefulness hormones which are determined by the amount of blue light your skin and eyes absorb.

Basically during daytime your body makes you wakeful and when the sun is gone it will make you sleepy. If you sleep outside of your biorhythm during daytime you‘re fighting against your wakefulness hormones and sleep worse.
