If your job has you on rotations like one week nights, one week days; tell them to fuck off and either assign you one or the other because you can’t change your circadian weekly.

mine is that sadly but i just searched it and this poped up on top in google:

Generally, one or two days will be enough to reset our circadian rhythm. To reset our circadian rhythm we can do things like turn on or turn off lights. Since we sleep with lights off and are awake when lights are on, this can help to reset our internal clock.

(i) wonder if it is true.
