I have tried on occasion to work night shift. It is OK for a few weeks but within months I reach extreme exhaustion falling asleep while operating dangerous machinery, despite sleeping during the day. I experienced a similar phenomenon working on a fishing boat where I simply never adapted to sea sickness and after weeks of throwing up almost all food and fluids it took months to crawl back to activity and recover including the pneumonia induced from my immune system and homeostasis being beat down.

Human body can be really bad at adapting to unworldly environments to the point you totally break down.
