A Night Nurse's Guide to Sleeping During the Day

Shift workers have a forty percent higher risk of sleep disorders. I talked to one who figured it out.

Her name is Jen. Not the same Jen from before — a new Jen. She's been a night nurse at St. Joseph's in Denver for eleven years. She works three twelve-hour shifts a week, 7 PM to 7 AM. She has two kids, a husband who travels for work, and a dog who doesn't understand why she sleeps during the day. When I asked her how she manages, she laughed and said "barely."

I spent an hour on the phone with Jen, picking her brain about how she sleeps during the day. Because most advice about sleep assumes you sleep at night. Blackout curtains? Sure. White noise? Fine. But what about the garbage truck that comes at 10 AM? What about the neighbor mowing his lawn at 2 PM? What about your kids coming home from school at 3:30? Night shift sleep is a whole different beast.

Jen told me she tried everything in her first two years. Melatonin. Prescription sleep aids. Eye masks that left marks on her face. Earplugs that hurt her ears. She tried sleeping right after work — from 8 AM to 2 PM. She tried splitting her sleep into two chunks — a nap after work and another before her shift. She tried blacking out her bedroom windows with aluminum foil — her husband called it the "serial killer look." Nothing worked perfectly. But over time, she built a system.

Here's Jen's system. After her shift ends at 7 AM, she stays awake until 9 AM. She does not go straight to bed. She says going to bed immediately after a night shift is a trap. Your body is still revved up from work, and the sunlight tells your brain "be awake." So she treats 7 to 9 AM as her "wind-down." She eats a small meal — not heavy — takes a warm shower, and reads something boring on her phone — no social media, just a novel or a news article. Then at 9 AM, she puts on her blackout mask — she found one that doesn't hurt her ears — turns on her white noise machine — set to "heavy rain" — and gets into bed.

She sleeps from 9 AM to 1 PM. That's four hours. Then she wakes up, eats lunch, takes care of her kids, does errands. Then she takes a second nap from 4 PM to 6 PM. Two hours. Total sleep: six hours. Not great, but she says it's enough. She tried sleeping a single block of six to seven hours during the day, but she always woke up groggy because she was interrupting her deep sleep. Splitting it into two blocks worked better — one block for deep sleep — the morning block — and one for REM — the afternoon block.

I asked Jen about naps. She said the afternoon nap is crucial. Without it, she crashes around 10 PM during her shift. But the timing has to be perfect. Too early, and she's not tired. Too late, and she can't fall asleep after her shift. She uses a nap planner to figure out the window.

She told me she uses the nap planner in "shift worker mode" — a setting that accounts for reversed circadian rhythms. It recommends a ninety-minute nap on her first day off to help reset, and twenty-minute naps during her shift if she has a break. She said the twenty-minute naps on shift are "the only thing keeping me from losing my mind at 4 AM."

Jen also tracks her sleep debt religiously. Because night shift debt accumulates faster than day shift debt. Your body is fighting its natural rhythm, so every hour of lost sleep feels like two.

She aims to keep her weekly debt under five hours. When it creeps up, she uses her days off to pay it down — not by sleeping twelve hours straight, but by adding an extra hour to her morning sleep block and taking a longer afternoon nap. She says "if I let my debt get above ten hours, I become a different person. A mean person."

One of the hardest things for night shift workers is social pressure. Friends and family don't understand why you can't go to lunch at noon. Jen said she lost friends early on because she kept saying no to daytime events. Now she's upfront: "I sleep from 9 AM to 1 PM and again from 4 PM to 6 PM. Don't call me between those hours. Don't text me. I will not respond." She said it felt rude at first, but now her friends respect it. The ones who didn't? She doesn't talk to them anymore.

I asked Jen about caffeine. She said she drinks coffee at the start of her shift — around 7 PM — and again at midnight. No caffeine after 3 AM. She learned that caffeine after 3 AM messes up her morning sleep. Even if she falls asleep at 9 AM, the quality is terrible. So she switches to water or herbal tea after 3 AM. She said "it's not fun, but neither is being a zombie."

Another client I worked with, a night security guard named Derek, had a different approach. He slept a single block from 10 AM to 5 PM — seven hours. He said it worked for him because he kept his bedroom completely dark — plywood over the windows, not kidding — and used a sunrise alarm to wake up gently. But he didn't have kids or a dog. His only distraction was his girlfriend, who worked days and was quiet when she came home. Jen, with two kids, couldn't do that. So her split schedule was better for her.

The lesson: there's no one right way to sleep during the day. You have to experiment. But the principles are the same: total darkness, cool temperature, white noise, consistent schedule, and strategic use of naps.

I also want to talk about transitioning between night shifts and days off. This is where most night workers struggle. On her first day off, Jen doesn't try to flip back to a day schedule. She sleeps her normal morning block — 9 AM to 1 PM — then takes a short nap — twenty minutes — around 5 PM, then goes to bed at a normal night time — say, 10 PM. That resets her for the next day. If she tried to stay awake all day after her last night shift, she'd be miserable and her sleep would be fragmented.

For night workers who travel or have irregular schedules, the jet lag adjustor can be helpful even if you're not flying. It helps with resetting your circadian rhythm after a stretch of night shifts.

Jen uses the adjustor in reverse — she inputs her night shift schedule as if she's traveling to a different time zone. It gives her a light exposure plan: when to seek bright light — during her shift, to stay alert — and when to avoid light — after her shift, to promote sleep. She said it was "weirdly effective."

If you're a night worker, here's my advice based on Jen and Derek and a dozen others I've coached. First, accept that you will never feel as rested as a day worker. That's just reality. Your body isn't designed for this. But you can get close. Second, prioritize your sleep like it's medicine. Because it is. Third, don't be polite about your boundaries. Your sleep is not negotiable. If someone calls you during your sleep window, don't answer. If they get mad, explain once. If they still get mad, that's their problem.

Jen told me something at the end of our call that stuck with me. She said "I used to feel guilty about sleeping during the day. Like I was lazy. Then I realized I work harder in twelve hours than most people work in three days. I earned this sleep." She's right.

P.S. Jen sent me a photo of her bedroom setup. Blackout curtains, a white noise machine, a fan, and a sign on her door that says "NIGHT NURSE SLEEPING — DO NOT DISTURB OR I WILL CRY." I respect her honesty.
