Main Question or Discussion Point
Often heard that it's not good for health to work through the night and sleep in the day, is there any medical support on this issue?? Or only a belief??
Certainly working different shifts (sometimes night shifts and sometimes day shifts) can cause a number of problems. But on your specific question about working consistent night shifts, here is a good article that includes references to a number of other studies:Often heard that it's not good for health to work through the night and sleep in the day, is there any medical support on this issue??

Our bodies and brains evolved to relax and cool down after dark and to spring back into action come morning. People who work the night shift must combat their bodies’ natural rest period while trying to remain alert and high functioning. It doesn’t matter whether they get enough sleep during the daytime, she says. All the sleep in the world won’t make up for circadian misalignment.
That’s especially dangerous for people whose jobs require them to be on high alert and make split-second, life-or-death decisions during the night, such as medical personnel or police officers. It’s common for police departments, for example, to require rookies and lower-ranking officers to bear the brunt of night shifts. They’ll often work a few days during normal daytime hours, then either work an extra-long shift that carries on until the morning, or take a day off, rest, then work a full night shift.
But that seesaw scheduling approach is a doubly bad idea, says John Violanti, PhD, an organizational psychologist who was a New York state trooper for 23 years. Not only are these highly stressful, performance-draining shifts being foisted upon the least experienced officers, but the young officers aren’t given time to adjust their sleep schedules for night work. Also, many officers seek night shifts to get overtime pay, he says. According to Vila’s research, roughly 40 percent of the nation’s 861,000 police officers work more than 12 hours a day — and a similar proportion suffer from a sleep disorder such as insomnia or excessive sleepiness.
Lack of sleep and disturbed biorhythms has been linked to a whole range of diseases, even directly to death; it is not so much sleeping in the day but instead loss of homeostasis at multiple levels.Often heard that it's not good for health to work through the night and sleep in the day, is there any medical support on this issue??
