I imagine most people can adjust to whatever time fits their needs (jobs), although it takes awhile. I seem to recall studies of folks in those “habitat” facilities where they couldn’t tell what time it was or see the sun. Some interesting stuff came out of it - but I can’t remember now!

My wife was just in the ICU for two weeks. And there is a thing called ICU Psychosis which does that. The last three days she was indeed losing her mind. Still after being out five days later she is having issues at night while trying to sleep. Crazy livid dreams, people talking to her who are not there when she is awake, Etc.

What's difficult is switching around too often. At the mine where I used to work, the operations people (haul truck drivers and such) had to work a horrendous combination of day shifts and night shifts, the exact details of which I have forgotten. A shift was 12 hours, from 6:00 to 6:00, and over 21 days a driver would work a total of 7 days and 7 nights, switching back and forth twice. Then he or she would get 7 days off before starting the four-week cycle over.
I don't think I could have kept that up for very long, but there were some workers who did it for decades.
