Shift work eating tips:Whole grain, carbohydrate-based and low-fat foods tend to make us sleepy, which makes them an excellent choice for a meal before bed. Protein-rich foods keep us alert, which makes them a good choice for meals and snacks eaten during an evening or night shift.
While shifts vary according to a healthcare facility or hospital, the typical night shift is between the hours of 11:00 p.m. and 7:00 a.m. Some nurses may start a shift as early as 8:00 p.m. At the end of a night shift, nurses return home where they usually rest and rejuvenate in the early hours of the day.
