Foods stay frozen longer if the freezer remains unopened, is full, is in a cool place and is well insulated. Usually food in a loaded freezer will stay frozen for two to four days, depending on its size. A half-filled freezer will keep food frozen only about 24 hours. Cover the freezer with blankets, keeping them away from the compressor, to help hold the cold.
Anxiety and depression indices also point to the likelihood of an adverse effect on mental health from shift work and long working hours. Nevertheless it must be remembered that, by and large, shift workers are a self selected population.
Not surprisingly, night shift workers often struggle with feelings of drowsiness and making the right food choices can help. Protein foods like tuna, eggs, string cheese, cottage cheese, peanut butter, turkey, and tofu can help increase alertness and focus, so try to incorporate these into your meals and snacks.
