How to Survive the Night Shift as a Pre-PA or PA

Maybe you are a pre-PA student whose CNA position is overnight, a PA student on a rotation with night stretches, or a practicing PA in the ER like me. Either way, these are the habits that keep me functional. While you are at work:

No caffeine past the first 2-3 hours of the shift. I know it sounds wild, but if you lean on caffeine all night you will either struggle to sleep later or crash around 4-5am.

No liquids within 4 hours before you want to sleep when you get home, so you are not waking up every hour to use the bathroom.

Lots of water leading up to that 4-hour cutoff, at least 60 oz, ideally from a large tumbler.

Snacks that keep your energy steady, like granola bars, overnight oats, bananas, berries, apples, and peanut butter. I personally do better grazing all night than eating one big meal.

Once you are home, wind down on purpose: use the bathroom one more time, shower if you need to, brush your teeth, and read for 15-30 minutes off your phone. If you take melatonin, take it now, and when the wave of sleepiness hits, go to sleep right then. Black out the room with curtains or an eye mask, and block daytime noise with ear plugs or a white noise machine.

I treat a stretch of 3-4 nights very differently than a single random night. For me, night shifts are any 8-12 hour shift starting after 5pm, whether that is 5pm-3am or a true 7p-7a. If you have the choice, it is easier to work up to the latest shift, but you may not control your own schedule, so this is easier said than done.

Say your stretch is four 9pm starts in a row. Here is roughly how I tackle it:

Day 1 (no shift): go to bed when you normally would and get a good, normal night of sleep. Let your body wake you naturally instead of forcing yourself to stay up and sleep in. I also avoid alcohol this night, since it hurts sleep quality even at a glass or two.

Day 2 (first night shift): around 4 or 5pm, take a nap, ideally 1.5 or 3 hours since a sleep cycle runs about 90 minutes. If you cannot sleep, at least rest quietly with a book or TV and no social media. Eat a full meal around 7pm and head to work.

Day 3 (second overnight): you get home around 8am, wind down, black out the room, and sleep as long as you can, which for me is about 4 hours. Wake up, eat (no caffeine yet), do your normal daytime things, then nap again around 4-5pm for 1.5-3 hours. That gets you to roughly 7-8 hours total.

Days 4 and beyond: repeat the day 3 pattern. Some people prefer to stay up in the morning and sleep one block from late morning to evening, and that works too. I just sleep poorly during the day, so the biphasic split works better for me.

On your last day of the stretch, to flip back, I typically wake up after that 4-hour block of sleep and just stay up. I will go to bed around midnight and feel pretty hungover most of that first day, but the next day I can wake up around 9am feeling much better rested and back to being a functional human. Then I rinse and repeat for the next stretch.

This approach really only works if your schedule comes in waves, like 3-4 nights on and 3-4 off. If you are doing one night on, one off, or other irregular patterns, you may have to experiment with several schedules before you find what fits your body. There is no single right answer, so give yourself grace while you figure it out. If you would rather not flip back and forth at all, some people simply embrace being a creature of the night and keep a consistent overnight schedule on their days off too.

Let's talk briefly about over-the-counter medicated sleep aids. First, a disclaimer: I usually do not use these because they make me feel like garbage. When I do, it is typically melatonin on the day after my last night working, so I can fall asleep around midnight. I do not love the grogginess many of the others cause.

Melatonin at 1-3mg is plenty, and more melatonin does not equal more sleep. Take it about an hour before you want to fall asleep, and when you feel sleepy, let yourself sleep, because if you fight it the window passes. As a side note, it can sometimes cause vivid dreams or sleep paralysis. Antihistamines are allergy medications with a sedating side effect. They help you fall asleep but often cause next-day grogginess, especially the longer-acting ones. Dimenhydrinate (Dramamine) has the shortest half-life, diphenhydramine (Benadryl) is moderate, and doxylamine (Unisom) is the longest.

Please ask your doctor before taking any of these if you are pregnant or have seizures, angle-closure glaucoma, an enlarged prostate, asthma, emphysema, or acute hepatic insufficiency.

Night shift is tough, but with the right caffeine timing, hydration habits, a dark and quiet sleep setup, and a schedule that fits your body, it becomes a lot more manageable. Experiment until you find what works for you, and protect your sleep like it is part of the job. If you are picking up overnight hours to build patient care experience, you are doing exactly the kind of work that makes a strong PA school applicant.
