The commute is often far more accessible, the pay is sometimes better, and night workers have more time during the day to run errands and do other things. As with everything, though, there are downsides, too. The most significant disadvantage to working the night shift is its negative effect on workers’ natural sleep cycles. Night shift sleep disorders – significantly shift work sleep disorder (SWSD) – are detrimental to individual health and can cause long-lasting effects.

What is a Shift Work Sleep Disorder?

People who work nights may experience several sleep problems due to their unconventional work schedules.

Night-shift sleep disorders may include insomnia or narcolepsy. Insomnia is when an individual has difficulty falling or staying asleep for long periods. On the other hand, narcolepsy is a condition that results in the afflicted person falling asleep suddenly at unpredictable times due to extreme sleepiness.

However, both conditions are merely symptoms of a more significant and overarching problem.

According to a random study involving 1163 participants:

“The prevalence of sleep work disorder was 32.1% among night workers and 10.1% in day workers.” And of those participants, Severe Shift Work Disorder “(SSWD) was present in 9.1% of night workers and 1.3% of day workers.” (source: NIH)

Furthermore, that same study found that:

The prevalence of insomnia and/or sleepiness was 32% in permanent night workers, 26% in rotating shift workers and 18% in day workers.”

However, a more extensive recent study suggests this problem may be far more prevalent than we had previously thought. Five studies were included in this analysis of 10,141 participants.

That study found that “The prevalence of insomnia in shift workers ranged from 12.8% to 76.4%, higher than estimated for the general population. Moreover, a higher prevalence was observed among women and singles, and there was no signi?cant variation with age and profession.”

While many of us could benefit from more sleep and better quality sleep, it’s undeniable that shift work sleep disorder is a far greater concern for those of you working night shifts or rotating shifts. SWSDs can also be referred to as night shift sleep disorder and night shift fatigue syndrome; they are all interchangeable.

What are the Symptoms of Shift Work Sleep Disorder?

Night workers and rotating shift workers experience many symptoms like insomnia and narcolepsy; between 25-30% of workers report these symptoms. If left unchecked and untreated, these symptoms can lead to a shift work sleep disorder diagnosis down the road.

Even workers who get enough hours of sleep can suffer fWoman with shift work sleep disorderrom these symptoms and this disorder. Our internal clocks are programmed for us to sleep at night. When we get the bulk of our rest during daytime hours, our bodies will try to wake us up repeatedly.

Why are we programmed this way? Shift work sleep disorder results from a mismatch between your internal clock and the external environment. Each of these affects both the duration of your sleep and the timing.

Historically, humans have risen with the sun and slept just after the sun had set. The visual cue from sunlight sets the schedule for our internal clock during a 24-hour day. And it’s only recently in our human history that working outside these daytime hours has become much more common.

Insomnia and extreme tiredness are not the only shift work sleep disorder symptoms.

People who suffer from SWSD are perpetually tired. They are sleepy whether they are working or at home. Often, they will feel exhausted even after sleeping for seven to nine solid hours. Even when they do sleep, the sleep they get does not feel energizing or refreshing. And good sleep isn’t something you can bank for a later time; it must be had each night.

Over time, people suffering from shift work sleep disorder will develop an extreme lack of energy and likely have difficulty concentrating on anything for a long time. These feelings can lead to depression or anger issues.

However, it’s not just those who suffer from SWSD who are affected. Many people find that their exhaustion and attitude hurt their relationships with others.

The symptoms of shift work sleep disorder will only increase if left unaddressed. Excessive tiredness and the symptoms it creates build up and get worse over time. While this may not sound like a huge problem, sleep is vital to life, like food, air, and water.

If you work an unnatural shift and have the following symptoms, you may be suffering from shift work sleep disorder:

  • Insomnia
  • Hypersomnia: excessive sleepiness at unwanted times
  • Decreased alertness
  • Lack of energy
  • Irritability and mood swings
  • Headaches
  • Difficulty concentrating
  • Always looking sleepy
  • Poor work performance
  • Memory issues
  • Struggling to stay awake
  • Falling asleep while driving

As many shift workers are employed in factories, imagine how decreased alertness can affect your job and safety.

If you have any of the above symptoms and feel you might have an SWSD, you should immediately talk to your healthcare provider. Remember, you can’t put sleep in the bank, and you cannot make it up later.

What are the Consequences of Shift Work Sleep Disorder?

High-quality sleep is as essential to your health as eating and exercising. Everyone is guilty of getting too little rest now and then, but skipping out on adequate shuteye regularly can result in long-term health problems.

Ongoing lack of sleep can lead to obesity, heart disease, kidney disease, high blood pressure, stroke, diabetes, and depression. Sleep boosts our immune systems and promotes overall mental well-being. Some people who experience long-term sleep issues turn to drugs or alcohol for relief, which can lead to addiction.

Furthermore, operating on too little sleep can be dangerous, especially if you have a high-pressure job that includes operating heavy machinery or saving lives in the medical field.

People who experience extreme drowsiness sometimes fall asleep for a few seconds without even knowing it, and in some professions, a few seconds can result in injury or even death.

Some researchers even believe sleepiness may have led to numerous significant catastrophes in contemporary world history, including the Chornobyl disaster, a nuclear power plant disaster in Pennsylvania, and Exxon’s massive Alaskan oil spill.

How to Diagnose Shift Work Sleep Disorder

Do you have this feeling?

The criteria for a diagnosis of an SWSD are:

  • It would be best to have insomnia symptoms when trying to sleep and/or suffer from excessive sleepiness while you wake.
  • You must be getting less sleep than is normal (7-8 hours are ideal) due to a work schedule that interferes with your internal clock and sleep schedule. Losing as many as four hours of sleep per night is typical.
  • You must suffer from symptoms consistent with your work schedule for three months or longer.
  • Your symptoms should not be attributed to a medical condition, medication side effects, poor sleep practices, or drug or alcohol abuse.

If you recognize any of the above in your sleep history, the first step is to schedule an appointment with your healthcare provider. At your appointment, your doctor will ask you many questions about your sleep patterns, sleep issues, work schedule, medical history, and medications.

A physical exam is the first step, but you’ll also be asked to keep a sleep diary for a few weeks. You may even be asked to conduct an actigraphy test at home.

An actigraphy test is non-invasive and painless. You wear an ankle or wrist monitor for a couple of weeks that will measure several critical metrics and help inform your physician’s diagnosis.

If your sleep diary and an actigraphy test indicate a disturbed sleep pattern, your doctor will diagnose you with an SWSD. However, additional tests like polysomnography (sleep study) or MSLT could be required if signs are inconclusive. They will want to rule out the possibility that another condition is responsible for your sleep issues.

These methods will help your doctor determine whether you suffer from shift work sleep disorder or some other night shift sleep issue. Then, they can choose a course of action to help them get better rest moving forward.

And while it’s not relevant to this guide, there are many types of sleep disorders you don’t want to confuse with an SWSD.

Causes of Shift Work Sleep Disorders

  2. Medical, like asthma
  3. Environmental, like drugs or alcohol
  4. Psychological, like anxiety or depression
  5. Night shifts or rotating, as you know
  6. Medications, as these affect people differently
  7. Genetics, like narcolepsy
  8. Age

  3. Do not nap during your waking time.
  4. Do not smoke cigarettes or ingest any nicotine.
  5. Do not watch the clock and put pressure on yourself.
  6. Sleep in a quiet, calm, and dark bedroom.
  7. Develop a consistent sleep schedule for waking and sleeping.

Also, noises from your devices or blinking lights will disrupt your sleep. And if using one of these devices before bedtime, your mind may be too stimulated to fall asleep.

If removing your electronic devices is problematic, you can turn off the wifi and the machines.
