Is working the Night Shift bad for your health?

hi Doc. Since May 10, 2017, I’ve started working on a night shift, sitting all the day long, from 8-5. I don’t smoke nor drink. I also sleep at least 8 hrs a day. My friends keep on telling me my kind of work could give me several health complications. They say that the body repairs itself (including the vital organs) during the wee hours of the day and I’m supposed to be resting during those hours, and not working. Is there any truth to this? What should I do to keep myself healthy while working on a night shift?
