Struggling to Sleep as a Shift Worker? Here's How to Cope

If you're a shift worker grappling with sleep issues, you're not alone. Studies have revealed that over a quarter of people who work non-standard hours suffer from Shift Work Sleep Disorder (SWSD), characterized by chronic issues staying awake during work hours and sleeping during desired ones.

The importance of securing adequate sleep extends beyond personal health and job performance. It also plays a crucial role in road safety, as nightshift workers face a higher risk of drowsy driving-related car accidents. However, strategies do exist to help you get a good rest, regardless of your work schedule.

Understanding Shift Work and Circadian Rhythms

Non-traditional work hours, such as night shifts, early morning shifts, or afternoon/evening shifts, are common among 15-30% of the workforce. As society increasingly relies on industries operating around the clock, the challenge arises when these schedules disrupt your circadian rhythm, the body's internal 24-hour sleep-wake cycle.

Catherine McCall, a sleep physician and assistant professor of Psychiatry and Behavioral Sciences at the UW School of Medicine, notes that our society would not function without a significant proportion of the workforce engaged in shift work. However, this can be challenging when your work schedule conflicts with your body's natural rhythm, leading to sleep problems.

The circadian rhythm is composed of countless biological clocks located in every cell in the body, coordinated by a master clock in the brain called the suprachiasmatic nucleus. This clock synchronizes with the day-night cycle by receiving cues from the outside world such as light exposure, food intake, exercise, and temperature. When these cues are disrupted by shift work, it can be difficult to realign the rhythm.

Impact of SWSD on Health and Safety

The misalignment between a person's circadian rhythm and work schedule can result in feelings of drowsiness during work hours. In addition, the homeostatic sleep pressure, or the pressure to sleep that builds as we stay awake, also intensifies the longer we're awake, reaching a peak during night shifts.

At the same time, the circadian alerting signal fades, and the brain increases melatonin production, contributing to increased drowsiness. This can be particularly dangerous when operating machinery or driving a vehicle. To make matters worse, when you get home after your night shift, your body may already have initiated the process of promoting wakefulness, making it difficult to fall asleep.

Chronic sleep problems related to SWSD can lead to a range of health issues, from hypertension and cancer to dementia and mental health disorders such as depression and anxiety.

Strategies to Overcome SWSD

While the best approach to avoiding SWSD-related health issues is to avoid shift work, albeit unrealistic for many, there are strategies to help you stay alert at work and sleep well when you get home.

Napping and Caffeine

Taking scheduled naps and caffeine intake can help combat the homeostatic sleep pressure and promote alertness during work hours. A short (15-minute) nap before a night shift can help reduce sleep pressure, while consuming caffeine during the first part of a shift can lessen homeostatic pressure. However, it's essential to avoid caffeine consumption in the eight hours leading up to your intended sleep time to avoid sleep disturbances.

Managing Light Exposure

In addition to managing sleep pressure, adjusting your circadian rhythm through light cues can help synchronize your internal clock with your work schedule. This involves getting light during the beginning of a shift and reducing light exposure at the end. If it's still light before work, spending time in sunlight or using a light therapy lamp at work can help regulate the body's clock. Conversely, wearing sunglasses and avoiding direct sunlight on your way home, coupled with dimming household lights and using blackout curtains or a sleep mask when preparing for bed, can help initiate sleep.

Melatonin, Routine, and Environment

Supplementing with melatonin, a hormone that promotes sleep, can also help regulate sleep patterns. A low (1-3 milligram) melatonin supplement can help promote sleep, but it's important to research trustworthy brands, avoid potential drug interactions, and be cautious to prevent overdosing, which can lead to side effects such as headaches, excessive sleepiness, trouble breathing, and vomiting.

Establishing a bedtime routine that includes activities such as reading, journaling, or listening to relaxing music can help signal to the brain that it's time to sleep. Creating a sleep-conducive environment by using white noise machines, earplugs, blackout curtains, or a sleep mask can also help eliminate distractions and promote sleep.

Adjusting Your Sleep Schedule

Through consistent application of these strategies, it's possible to shift your circadian rhythm to better align with your work schedule. However, the degree of adjustment and its sustainability depends on factors such as the timing, frequency, and consistency of shift changes, and any underlying health conditions or medications.

Conclusion

Managing sleep issues related to shift work requires a combination of behavioral, environmental, and lifestyle approaches. By employing strategies such as optimal light exposure, consistent sleep schedules, strategic caffeine and nap timing, creating a sleep-conducive environment, maintaining good sleep hygiene, and gradual adjustments to sleep patterns, shift workers can better manage sleep disruptions and maintain their health and performance.

1. The chronic issues with staying awake during work hours and sleeping during desired ones, known as Shift Work Sleep Disorder (SWSD), are not only detrimental to a shift worker's personal mental health, but they also pose a risk to the safety of the workplace-wellness environment, especially when it comes to operating machinery or driving a vehicle.
2. In addition to long-term health issues like hypertension, cancer, dementia, and mental health disorders such as depression and anxiety, SWSD can significantly impact health-and-wellness, leading to increased drowsiness during work hours due to the misalignment between a person's circadian rhythm and work schedule.
3. To cope with sleep problems associated with shift work and maintain overall well-being, strategies such as scheduled napping, caffeine intake management, light exposure adjustments, melatonin supplementation, and consistent bedtime routines can help shift the circadian rhythm to better align with the work schedule, promote alertness during work hours, and facilitate sleep when desired.
