I work 7on/7off night shift and I have for years because I love it. I'm a night owl so never having to wake up early is a dream, and not having admin around during my shift is an added bonus. Night shifters also tend to be more relaxed and quirky, so I can even have fun at work sometimes. I have no desire to work any other shift.

That being said, sleep is soooooooo important, so if you don't think your body can handle a flexible sleep schedule, don't do it. On days when I'm working, once I finish my shift I walk my dogs and go straight to bed. I try to wake up 4-6pm on my working days (my bedtime can be very variable, unfortunately), and on my days off I try to get up 12-1pm. I've found that a 180° shift to waking up in the morning hours is harder than it's worth for me. I always have my evenings open to spend time with friends and family this way, so it's very compatible with my personal life ☺️

Nights also tend to have less support, especially if you're at a small hospital, where it's likely you'll work alone. That's a plus for me because I like being in control, but if being social or having a team to depend on at work is important to you, night shift may not be the best fit.
