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.
If I have the time and energy, I will exercise before going into work to experience daylight and work off some stress. The day after my last night shift, I will try to short sleep and wake up after only a few hours to make the most out of my day and get back on a normal schedule. I also try to go to bed early that night to catch up on sleep. Napping also helps out.
