Sleeping Like a Boss Night Shift Workers Share Their Secrets

Heading to work after the sun sets has become common in the U.S., but what does that mean for the health of night shift workers? According to the U.S. Census Bureau, an estimated 11.4% to 14% of American workers perform their jobs on a “non-standard schedule,” meaning they don’t work in the daytime and may not have predictable work hours. So, what’s the scoop on the effects of working the night shift?

Night shift work, as defined by the National Institutes of Health, disrupts the body’s natural circadian rhythm – its internal clock that regulates sleep patterns. This 24-hour cycle is highly influenced by light exposure and darkness. In the morning, when we’re exposed to natural light, our bodies receive a wake-up call. As the evening approaches and the sun sets, melatonin, a hormone that promotes sleep, kicks in. Disruptions to this delicate rhythm can lead to a whole host of issues, including sleep problems, mood irregularities, drowsiness, and slower cognitive processing.

But that’s not all! Chinese researchers report that night shift workers are at a higher risk for heart attack and diabetes. A poor diet could be partly to blame. An Australian study found that shift workers on rotating schedules are at higher risk for diabetes due to their frequent meals and excessive snacking. If that’s not enough, there’s even something called “shift work sleep disorder” to contend with. So, what’s a night shift worker to do?

Let’s start with the most important action: setting aside enough time for quality sleep. According to Professor Emerson M. Wickwire, PhD, from the University of Maryland School of Medicine, 7 to 8 hours of uninterrupted rest is a must. But it’s not just about the quantity of sleep; it’s also about using daylight to your advantage.

A study review conducted by Korean researchers found that light therapy is the most effective way for shift workers to sleep longer, as it can adjust the body’s circadian phase. So, bring out the light box! Exposing yourself to sunlight upon waking can also help regulate your body’s rhythm. If you find yourself going to bed while it’s still light out, don’t fret. Embrace the power of blackout curtains and a sleep mask.

But hey, this advice isn’t just for night shift workers. Even those working regular daytime hours can benefit from optimizing their sleep. There will be days when a full night’s rest seems impossible, but fear not. Day workers have their own tips and tricks for maximizing sleep around the clock.

Let Yourself Feel Tired

Josh Hinton, a U.S. merchant mariner, suggests embracing fatigue and being patient with the process of adjusting your sleep schedule. He should know, having worked as a night cook on a ship. Your body won’t immediately switch, so try to sleep more during the day and less at night.

Use Reverse Sleep Hygiene

Hinton also suggests flipping the script on sleep hygiene. Instead of stopping caffeine intake at noon, indulge in a cup of joe in the evening, but aim to cut it off by midnight. It’s all about recalibrating.

Try the Dark Glasses Trick

Valerie Sinady, a night nurse practitioner, has a brilliant suggestion: wear really dark sunglasses when you’re getting off work. Darkness acts as a signal to fall asleep, and these safety glasses used for welding can be a cost-effective solution.

Nap Strategically

Carlos da Silva, a physician assistant with experience working on extended shifts, recommends integrating strategic naps into your day. Even if you can’t consistently get a full night’s sleep, a well-positioned nap can help keep you alert and ready for shut-eye when you finally get home. And for those times when you need to stay up later than usual, a “coffee nap” might just do the trick. A study from the University of South Australia found that drinking 200 milligrams of caffeine and then taking a 30-minute nap increased alertness upon waking.

Keep Regular Mealtimes

Debbie Gerken, a certified registered nurse, suggests maintaining consistency in your meal schedule. Try having breakfast when you get home from work to keep your digestive patterns aligned with your off days. And don’t forget, certain foods can actually promote sleep. Malted milk, fatty fish, tart cherries, and kiwi are all sleep-friendly options worth considering.

Create the Right Sleep Environment

Amy Karim, an MRI technologist and night shift worker, has mastered the art of sleep setup. A dark, cool, and quiet room is crucial. Earplugs and a white noise machine can help create the perfect atmosphere for quality rest. Just be cautious with melatonin supplements, as higher doses may actually disrupt sleep.

And remember, timing is everything. Gradually shifting your sleep schedule by going to bed and waking up slightly earlier each day can help you ease into your desired sleep routine. Before bed, engage in calming activities like reading, deep breathing, or meditation to set the stage for a restful slumber.

Phew! That’s a lot of information to absorb. But sleep is important, folks, so it’s worth exploring these strategies to improve the quality of your rest. If you’re still struggling with sleep woes, don’t hesitate to seek professional advice from your doctor.
