Shift work can be brutal, but it doesn't have to be. Welcome to a healthy shift. My name is Roger Sutherland, certified nutritionist, veteran law enforcement officer, and 24-7 shift worker for almost four decades. Through this podcast, I aim to educate shift workers using evidence-based methods to not only survive the rigors of shift work, but thrive. My goal is to empower shift workers to improve their health and well-being so they have more energy to do the things they love. Enjoy today's show. You've just worked all night and you are exhausted. You've been thinking about your bed for hours. Eyes hanging out of your head. You're just wondering if you can go on. You drive home, you're telling yourself that the second your head hits the pillow, you're going to be fast asleep and it will all be over. Then you get home, you get into bed, and suddenly you can't sleep. Or maybe you do fall asleep because you're exhausted. But three or four hours later, your eyes open. You look at the clock. Oh my God. You're still exhausted and you desperately want to go back to sleep. But your body's got other ideas. How to sleep after night shift. Or why can't I sleep after night shift? How to sleep during the day? Who's asked yourself those questions? Or even how to get a better sleep when you're working nights?

The Daytime Sleep Struggle

SPEAKER_00 1:41

If that's you, this episode is for you. Because there is something every night shift worker needs to understand. Being exhausted does not automatically mean that your body is ready for a good quality sleep. And once you understand why, you can start doing something about it. Welcome to a healthy shift. My name is Roger Sutherland. I'm a night shift and sleep specialist, also a veteran 24-7 shift worker of over 40 years. And I help shift workers and 24-7 organizations to better understand the impact of working against their human biology. Today we're talking about one of the biggest problems facing night shift workers. How do you actually sleep after night shift? And why is sleep after night shift so difficult? So let's start with the most important point. First of all, you are trying to sleep at the wrong biological time. And that is the reality of night shift. Humans are naturally a diurnal species. We are biologically designed to be awake and active during the day and asleep at night. Now, I know what some people will say, oh, but I'm a night owl. Now, I personally have always been better at night. I preferred working nights. And yeah, of course, there are differences between individuals. Some people naturally prefer earlier sleep and wake times, and others prefer later sleep and wake times. We call this your chronotype. But being a night owl does not suddenly make you a nocturnal animal. Your body still responds to the 24-hour light and dark cycle, and you still have a circadian rhythm. That biological clock that just keeps ticking away. You still have those biological processes that change across the day and the night. And when you finish the night shift and try and sleep during the day, you're literally working against those processes. And this is why daytime sleep is often shorter and more fragmented than normal nighttime sleep. It's not simply that you're bad at sleeping, it's because your biology and your work schedule are in conflict. So let's talk about sleep pressure

Sleep Pressure Versus Body Clock

SPEAKER_00 4:02

and your body clock. To understand how to sleep better after night shift, I want to explain two things. Sleep pressure and your circadian rhythm. Let's keep this incredibly simple. The longer you're awake, the more pressure that builds for you to sleep. I want you to think of it like filling a bucket. The longer you're awake, the fuller that bucket becomes. By the time you finish a 12-hour night shift, you may have been awake for a very long time. So your sleep pressure is high, and that's why you feel exhausted. But there is another system working at the same time, and this is your circadian rhythm. It's your internal biological clock. As morning arrives and the sun comes up, your circadian system begins to promote wakefulness, and your body starts receiving signals that say, hello, it's daytime, time to be awake, time to be active. So now we have two competing systems. Your sleep pressure is saying, we need to get to bed and sleep, and your circadian rhythm is saying, hello, wake up. And this helps to explain one of the strangest experiences of the night shift: that you can feel absolutely exhausted and still struggle to sleep. So what's the biggest mistake that night shift workers make? One of the biggest mistakes that night shift workers make is believing that sleep starts when they get into bed. And it doesn't. Your sleep after night shift is influenced by what happened before you get anywhere near that bed. Think about your final few hours at work. How much caffeine have you consumed? What have you eaten? How much artificial light have you been exposed to? How stressful was the end of your shift? What happened on your drive home? Was the sun up? What did you do when you walk through the front door? Because all of these things matter. Because you can't spend the entire night telling your body to stay awake and alert and then expect it to just immediately switch off because you've closed the bedroom door. Your body just doesn't work like that. And you need to create a transition. And I call this building the runway to sleep. And the better you become at creating that runway, the better the chance you give yourself of sleeping after night shift. Now we have to talk about caffeine because caffeine and night shift are almost inseparable. Relax. I'm not taking your caffeine off you. I understand we need it. I understand why we need it. You're tired. You need to concentrate. You've got responsibilities. You might be a nurse looking after patients. You could be driving vehicles, you could be driving emergency vehicles, operating equipment, making critical decisions. So you have to have caffeine. There

Building A Runway To Sleep

SPEAKER_00 7:03

may be another one. Then someone does a coffee run at 2 a.m. and you think, why not? I could really use it. The problem is that caffeine has a long half-life. And that means hours after drinking it, a significant amount can still be circulating in your system. So if you're drinking coffee late in your night shift, that caffeine may still be affecting you when you're trying to sleep. And here is the important part you can still fall asleep. And people often say to me, Roger, caffeine doesn't affect me. I can just drink an espresso and go straight to sleep. Falling asleep is not the only issue. Caffeine can still affect the quality and the structure of your sleep. So one of the first questions I ask night shift workers struggling with sleep is, When do you finish your last caffeine? What rules have you got in place around that? And how much caffeine do you actually drink? When do you drink it? Because timing matters. And let's not forget those Coke Zeros, 40 milligrams

Caffeine Timing And Sleep Quality

SPEAKER_00 8:07

of caffeine. Coca-Cola, 40 milligrams of caffeine. As a general principle, I want night shift workers thinking about using caffeine strategically. Of course, you need it. So use it earlier in the shift, but not continually drinking it throughout the night just to drag yourself to the finish line. It's important. It's another one of those percenters that kills us. We need to manage our light. We need to talk about light. Light is the strongest signal to your biological clock. And this creates a major challenge for the night shift worker. You've been awake all through the darkness. You finish work at seven o'clock and you walk outside and the sun is up and you're driving home. And you are exposed to bright morning light. And what signal does that send to your brain? Hello, it's wake up time. Be alert, it's daytime. And when you arrive at home and say, right, now let's go to sleep, conflicting signals. This is why understanding light exposure is so important for the night shift worker. Now, I want to be careful here because I see far too much generic advice telling every night shift worker to do exactly the same thing: wear dark glasses, avoid all light, block everything. But your light strategy really does depend on context, and everyone's different. Are you going to be working another night or night shift tonight? Are you finishing your final night shift? Are you trying to move back onto a daytime schedule? What does your roster look like? What time do you need to wake up? And this is why I constantly come back to the same point. Generic tips are not enough. You need your own strategy that matches your roster. But if your goal is to sleep soon after getting home from night shift, you need to think about reducing the signals that are telling your body to wake up. Remember, I'll say this over and over again.

Light Exposure And Your Roster

SPEAKER_00 10:12

Your body is literally responding to the data that you're giving it. Now, your post-night shift routine really matters. What do you do when you get home from night shift? Because this matters a lot more than most shift workers realize. Do you get home and then just do a quick bit of housework? Do you scroll through your phone? Do you flick on the TV to relax? Do you start answering emails? Do you have yourself a large meal or a meal? Do you sit on a social media for an hour? Or do you have a repeatable routine that tells your body, working day over, we're preparing for sleep? Now your routine does not need to be complicated. In fact, I would argue it's actually simpler. The simpler it is, the better. Because the more you have to think about it, the more stress you create, the harder it is to sleep. You get home, reduce the stimulation, you keep your environment calm and dark, you follow the same sequence of behaviors, you have yourself a hot shower, you get into bed, and you do yourself some gentle breathing. You might read a book, just read. Prepare the bedroom, then you go to sleep. The actual routine may look different for different people, but what matters is repetition. Because your brain learns patterns. And if you repeatedly follow the same behaviors before sleep, those behaviors can become signals. Work is finished, the day is over, it's time to sleep. So, what do we do about eating after night shift? Because this is another big one. Should you eat before sleeping after

Post-Shift Routine That Works

SPEAKER_00 11:55

night shift? And the answer is it depends. Now I know that's not the answer that people want, because people want a simple yes or no. But your hunger, food intake during the shift, health needs, and sleep timing, it all matters. What I don't recommend is finishing night shift and eating an enormous meal immediately before going to bed. You have worked all night. Your body is tired, your digestive system has its own biological rhythms. And now, if you give it a huge amount of food to process while you're trying to sleep, this may not help. But I also don't want someone lying in bed genuinely hungry and unable to sleep because they're thinking about food. So this is where understanding your nutrient timing across the entire shift becomes important. What you do at 7 a.m. is often influenced by what you did at midnight. Again, you need to stop looking at individual behaviors in isolation because the whole system matters. Let's talk about the bedroom. Because your bedroom needs to become a sleep cave. If you work night shift, your bedroom is the most important environment of your life. Because daytime sleep is already extremely difficult. You do not need your environment making it harder for you to sleep. Your bedroom, stand at the door and look in. It needs to be

Food Timing Before Day Sleep

SPEAKER_00 13:22

dark. Now, how dark? I'll tell you, lie in your normal sleeping position, hold your arm out at full length, turn your hand to face you. If you can see your hand, it's not dark enough. That is literally a simple rule. Hold your hand at arm's length, and if you can see it, it's not dark enough to sleep. It needs to be cool. It needs to be quiet and it needs to be comfortable. It needs to be uncluttered. Now, when I say dark, I mean dark. Not, oh, I've got curtains, but there's a bit of light coming in, you know, through the sides. Dark. Blackout blinds. The eye mask. Life changing. So totally underestimated. And people say, oh no, I don't like it. What have you tried? Have you tried a good one? Because when you try a good one and you get used to it, you've got to persevere with it like everything else. And then it just changes your life. Then there's the noise. While you're sleeping, the rest of the world is awake and going about

Turn Your Bedroom Into A Sleep Cave

SPEAKER_00 14:30

its business. The neighbour's got to mow the lawn. The delivery drivers are knocking on doors, dogs are barking, kids are playing, phones are ringing. You probably need sleep buds or earbuds. Something that plays white noise. Now you might think, oh, I find that annoying. But your brain actually likes it. It focuses on it and you don't hear the heater kicking in and out, the hot water service clicking on and off, the fridge cutting in and out. You don't hear those things because your brain focuses on that white noise. Get used to it. Sleep buds. Or some other strategy to reduce the unpredictable environmental noise. And your phone, it's got to be on do not disturb. There is nothing more important. Your sleep after night shift has got to be protected. You wouldn't repeatedly wake someone at 2 a.m. expect them to function well the next day. Yet night shift workers are expected to tolerate interruptions to daytime sleepers, so it just doesn't matter. And it does. So protect your sleep opportunity. And I'll give you another tip, and this is probably the most important. Don't chase the perfect sleep. That creates sleep anxiety. And this is something that I see and hear a lot of. You know you need to sleep. You know you've got another night shift coming. You look at the clock, you calculate how many hours you've got left. If I fall asleep now, I can get seven hours, 20 minutes later. Now I can get six hours and 40 minutes. Oh, oh, now it's six hours and 20 minutes. And suddenly you're stressed out about not sleeping. And that makes sleeping harder. I'd really like you to understand something. You can't force yourself to sleep. You've got to create the environment for sleep. And when you do that, you manage your environment, you manage your caffeine, you manage light, you can create a wind-down routine, you can use relaxation and breath work, but you can't command your brain to become unconscious. So stop chasing that perfect sleep. Just focus on creating the best possible sleep opportunity. That is what you can control. And then your body will take care of the rest. I promise you it will. Now, what if you wake up after about four hours? And this is one of the most common frustrations for night shift workers. You fall asleep, four hours later, wide awake. What happened? Remember what we talked about earlier. Your sleep pressure that helped you fall asleep. But as you sleep, that pressure is reduced, the bucket empties. Meanwhile, your circadian system is promoting daytime wakefulness. So as your sleep pressure decreases, staying asleep becomes more difficult. And this is another reason that daytime sleeper can be shorter

Stop Sleep Anxiety And Clock Watching

SPEAKER_00 17:14

than nighttime sleep. So what can you do? First of all, we don't panic, we just accept it for what it is. Don't immediately start catastrophizing about how terrible tonight's shift is going to be. And don't lie in bed getting increasingly frustrated for hours. Now, depending on your roster and circumstances, you may use another sleep opportunity or a strategic nap before your next shift. Again, context matters. But the important thing is understanding why this happens. Your body isn't failing you, it is actually responding to powerful biological signals. So let's go through a simple system for sleeping after night shift. Let's make it practical. If you want to get better sleep after night shift, I want you to think about five things. And write them down. Number one, you've got to manage caffeine strategically. Think about when you need caffeine rather than continually drinking it through the night. I have a rule at 12 o'clock. If you're on day shift, cut your caffeine at 12. If you're on night shift, cut your caffeine at 12. The

Why You Wake After Four Hours

SPEAKER_00 18:19

difference that that makes is a simple principle and it will change your life. It'll make such a big difference for you. Number two, you must manage your light exposure. Understand, light is sending the most powerful timing signal to your biological clock. It must be pitch black. I spoke about the hand before. Keep that in mind. Number three, create that runway to sleep. Stop expecting your body to go from highly alert and stimulated to a sleep in five minutes. Build yourself a repeatable post-night shift routine. Number four, protect your bedroom. Dark, cool, quiet, comfortable. And number five, stop chasing the perfect sleep. Remember, if you create the best possible conditions, you are giving your body the best opportunity and it will take care of the rest. But there's one more thing, and it may be the most

Five-Step System For Better Sleep

SPEAKER_00 19:25

important. Consistency always beats perfection. While night shift workers often want the perfect routine, the perfect supplement, the perfect sleep schedule, the perfect dancer, I'm gonna be clear, it doesn't exist. Because your roster changes, your responsibilities change, your family life changes. Things happen. What matters is creating systems that you can actually repeat. So if your sleep routine is complicated, that you can only follow it on the perfect day, it's not a very good system. I'd rather you have a simple five-step post-night shift routine that you can follow consistently than 25 different sleep acts that you use occasionally. Your body loves rhythm. Your body loves predictable signals, your body loves consistency. And while shift work will always create challenges for your circadian rhythm, we can work to reduce the biological chaos. So where do I start today? So if you're listening to this and you're thinking, Rog, I'm doing everything wrong. Don't try and fix everything today. Just choose one thing. Let's put a rule in place about caffeine. Finish it at midnight. Finish it at midday. And just drink water. Just choose one thing. Look at your caffeine. Look at your bedroom. Look at your post-night shift routine. Look at your light pressure. Choose the biggest problem, the one thing that you think could actually be causing the most grief. Is it light? Is it your bedroom? Is it heat? What

Consistency Beats Perfection

SPEAKER_00 21:02

is it? Caffeine. Start there. Because one of the biggest mistakes I see shift workers make is trying to completely overhaul their whole life overnight. You've got enough on your plate. That won't work. It's got to be small behaviors repeated consistently. And that is how we build a system that works. So how do you sleep after night shift? So start by understanding that being tired and being biologically ready for sleep are not the same thing. Your sleep pressure matters, your circadian rhythm matters. Caffeine matters, light matters, food timing matters, your environment matters, and your routine matters. And the goal is not to find another random sleep hate. The goal is to understand your biology and build a repeatable system around your shift working life. In relation to the eye mask and in relation to the sleep buds, or I can talk about the gummies, the sleep gummies. On my website, link in the show notes, a healthyshift.com. If you go up to resources at the top of the page and then you go to recommended products, there is a list with the earbuds, the sleep mask, the gummies, the mattress, the mattress topper, all of those products that will help you to sleep. That list has been put together to help you, the shift worker, who are combating everything that I've listed above there. They will help you. I have used them, I still use them, they've been tested, I endorse them. There's many products that don't make that page, but those ones have because they work. If you found this episode because you search for how to sleep after night shift, why you can't sleep after night shift, or how to get a better daytime sleep, I honestly hope it's helped you to understand what is actually going on. And more importantly, I want you to know how you can go about fixing that. So if you know another nurse or a paramedic, police officer, firefighter, dispatcher, call taker, or a night shift worker who finishes work completely exhausted but still struggles to sleep, can you do me a favor?
