Long shifts are hard for nurses, especially when you reach the 8-hour mark and have multiple patients in your charge. Finishing early is not an option. Choosing the right foods to keep you fueled is one thing you can control.
This guide covers healthy snacks to keep your energy steady that you can prep the night before and eat in the seconds you get on shift.
Why does the mid-shift crash happen?
Steady energy comes down to how fast glucose enters your bloodstream.
A snack made of simple sugar, like a candy bar or a sweetened coffee, triggers a matching insulin surge, followed by an energy dip.
Whole foods work differently. When you pair a carbohydrate with fiber, healthy fats, or protein, your digestion slows, and glucose is released slowly. Eating healthy snacks keeps your energy level stable when it's hour 7 or 8 of your shift.
Nutrients that help when your body is tired
When you are running on empty, a few key nutrients do the heavy lifting, and knowing which ones makes it easier to pick the best foods for low energy and fatigue.
- Complex carbohydrates: Fuel your body, and when eaten in conjunction with fiber, they release glucose gradually instead of all at once. Choose oats, whole fruit, and vegetables.
- Iron: Carries oxygen to your cells, and low iron levels are among the most common causes of lingering fatigue. Leafy greens, pumpkin seeds, and edamame contain iron.
- Magnesium: Helps your cells produce adenosine triphosphate (ATP), the molecule that powers everything you do. Pumpkin seeds, almonds, and spinach are rich in magnesium.
- Vitamin B: Helps your body convert food into usable cellular energy. Eggs, bananas, and whole grains all supply vitamin B.
- Vitamin C: Helps your body absorb iron, and it has been linked to reduced physical fatigue. Bell peppers and citrus fruits are good sources of vitamin C.
- Potassium: Carries the electrical signals your nerves and muscles rely on, and low levels show up as weakness and cramping. Potassium is found in bananas and avocados.
- Omega fatty acids: Omega-3 fatty acids can support focus and mental stamina through the second half of a shift. Walnuts, chia seeds, and flaxseed are the best plant sources.
- Water: Many people forget about water, but even mild dehydration can feel exactly like fatigue.
Foods rich in these nutrients serve as clean, natural energy snacks that fuel your body without a sugar crash.
How to build energy that lasts
The best energy boosting snacks all follow one pattern: pair a quick-fuel food with a slow-fuel one.
Quick fuel is fruit or simple carbohydrates, which give you instant energy your body can use right away. Slow fuel is nuts, seeds, vegetables, whole grains, or protein, all of which slow digestion so the energy lasts.
Fruit paired with nuts or seeds
Fruit gives you fast, natural sugar, while adding nuts or seeds slows the release of energy and adds minerals your cells use for fuel.
The following pairings also make great quick-energy snacks for nurses who sometimes have only a minute to eat:
- Bananas with pumpkin seeds
- Medjool dates stuffed with almonds
- Pear slices with walnuts
- Sliced strawberries with sunflower seed butter
Vegetables and legumes that fuel you
Vegetables provide fiber, and legumes provide plant protein. Eaten together, they rank among the best healthy afternoon energy snacks for work when your focus starts to fade.
Here are some yummy snack examples:
- Edamame with toasted sesame seeds
- Cucumber slices with guacamole
- Mini sweet peppers with hummus
Protein snacks that hold up on shift
High-protein energy snacks keep you feeling full for longer. Eating protein can also help you stay awake on the night shift because it steadies your blood sugar for hours.
Try out these delicious high-protein snacks:
- Hard-boiled eggs with cherry tomatoes
- Chia seed pudding made with unsweetened almond or soy milk
- Homemade energy bites with rolled oats, ground flaxseed, peanut butter, and raisins
Keep a stash of high-protein snacks at your station for long stretches when a real meal isn't happening any time soon.
Prepping snacks around a 12-hour shift
Nurses need a snack in reach when a slump hits, so a little prep goes a long way. Here are some quick and easy techniques you can use to avoid a mid-shift dash to the vending machine:
- Portion bite-sized snacks into small containers, so that you can eat them in free moments during your shift.
- Keep a labeled stash in the break room fridge, or pack a small insulated bag for anything that needs to stay cold.
- Choose no-cook options like a handful of nuts or fruit so a busy morning does not derail you.
- Remember to drink water alongside your snack, because fatigue often reads as hunger when it may actually be a sign of mild dehydration.
Healthy snacks can make a difference in your shift
Nurses spend 12 hours making sure other people are fed and looked after, but it is easy to let your own eating slide to whatever is fastest.
Good nutrition is part of self-care and also provides the energy you need for good patient care.
Packing your own snacks costs you a few minutes the night before and saves you the 3 p.m. decision between a vending machine and nothing at all. It also means the food waiting for you is the food you chose, which matters during shifts when very little else is in your control.
Ultimately, this comes down to taking care of yourself. Optimize your day by giving your body fuel it can use for hours, not minutes.
