A Night Nurse. Why?

I have been a night NICU nurse off and on for the last 3 years. Currently I am working nights, meaning I work from 6:30 pm to 7am the next morning. I think it's hard for the day working world to totally grasp this life unless you've experienced it. I think there is everything stacking up AGAINST working the night shift compared to the alternative. It is difficult to sleep during the day, it's difficult staying up all night, your temperature shifts at certain hours, your food usually doesn't digest well, it's extremely hard not to gain weight, most night shift workers have health issues, your first day off really isn't a day off because of the fatigue, you can't sleep well during the night on your nights off, etc. I could go on and on. BUT... there is a comfort doing the work I do in the middle of the night. There is a calmness and serenity being with a patient without all the hustle and bustle of the day's business as usual. Maybe it is more of the ambiance for me. The softer lighting to help a baby establish their days and nights, or the quieter room to hold a baby and talk to them in. Sometimes I can't believe I actually get paid to do what I do compared to other nursing positions. I choose to work nights because it helps me to be the type of NICU nurse that I want to be. I realize I won't be able to do this forever. But for now I cherish the night work.
