Shift work sleep disorder (SWSD) is a chronic condition that affects people who work outside the hours of 6 am and 7 pm, including fixed and rotating shifts. It is a circadian rhythm sleep disorder characterized by insomnia, excessive sleepiness, or both, resulting from a misalignment between an individual's body clock and their work schedule. The disorder can lead to significant sleep loss, with the average person losing one to four hours of sleep per night, and it can have a negative impact on their health, well-being, and safety. While it is not considered a permanent disorder, it can be long-term and interfere with an individual's life, and it often goes undiagnosed.

What You'll Learn
Shift work disorder is a chronic condition
Shift work disorder (SWSD) is a chronic condition that affects people who work outside the hours of 6 am and 7 pm, including fixed and rotating shifts. It is a type of circadian rhythm sleep disorder, which means that it is caused by a misalignment between an individual's body and their circadian rhythms, also known as their "biological clock," which regulate the sleep-wake cycle. This misalignment can lead to insomnia, or difficulty falling and/or staying asleep, and excessive sleepiness during the day. The average person with SWSD loses one to four hours of sleep per night, which can have significant impacts on their health, well-being, and safety.
The symptoms of SWSD can vary depending on the individual's specific shift. For example, those who work early morning shifts may experience different symptoms than those who work night shifts. Additionally, environmental factors such as marriage, family, and social pressures can contribute to sleep loss for those with SWSD. Overall, SWSD is estimated to affect 10-40% of shift workers, and it can have serious consequences if left untreated.
The chronic nature of SWSD means that it is a long-term condition that can interfere with an individual's life. The disorder can impact an individual's ability to fall asleep and maintain sleep, leading to chronic sleep deprivation. This can result in decreased alertness and increased risk of accidents, such as falling asleep while driving. Additionally, SWSD has been associated with various health risks, including decreased bone mineral density, increased risk of fractures, low fertility, and issues during pregnancy.
To diagnose SWSD, a doctor will use specific criteria, such as the International Classification of Sleep Disorders or the Diagnostic and Statistical Manual of Mental Disorders. They will ask questions about sleep patterns, disturbances, and the type of shift worked. They may also request a sleep diary and information about medical history and medications. It is important to rule out other sleep disorders or underlying conditions that may be causing the symptoms. Treatment for SWSD may include lifestyle changes, sleep aids, and behavioural or pharmacological therapy.
While SWSD is a chronic condition, there are ways to manage the symptoms and improve sleep quality. These include maintaining a regular sleep schedule, taking breaks between shifts, limiting caffeine intake, and creating a dark and quiet environment for sleep. Additionally, employers can implement measures to help keep their workers safe, such as keeping the workplace cool and bright to increase alertness.

Circadian rhythm disruption
Circadian rhythm, or our "biological clock", is a 24-hour cycle that regulates our sleepiness and wakefulness at set times throughout the day. Our circadian rhythm is largely guided by natural light and darkness. During the day, our retinas perceive sunlight and signal the brain to release hormones like cortisol that keep us feeling alert and energized. As the sun sets and light fades, our brain produces melatonin, which induces sleepiness and relaxation.
Shift work sleep disorder (SWSD) is a circadian rhythm sleep disorder that affects people who work non-traditional hours, including night, early morning, and rotating shifts. The disorder causes insomnia when workers attempt to sleep and/or excessive sleepiness while they are at work. The specific symptoms of insomnia and sleepiness depend on the shift worked. For example, workers who clock in between 4 a.m. and 7 a.m. often have trouble falling asleep, while those with evening shifts tend to wake up during the night. The average person with SWSD loses one to four hours of sleep per night.
The non-traditional work schedule can disrupt a person's circadian rhythm, causing a misalignment between the body and the circadian rhythms that regulate the sleep-wake cycle. This can lead to significant issues with falling asleep, staying asleep, and unwanted sleepiness. SWSD is a chronic, or long-term, condition that can negatively impact a person's everyday life. It can also lead to major health concerns, including obesity, metabolic syndrome, type II diabetes, gastrointestinal dysfunction, compromised immune function, cardiovascular disease, excessive sleepiness, mood and social disorders, and increased cancer risk.
While SWSD is a chronic condition, it is not necessarily permanent. Lifestyle changes, light therapy, and/or medication can help treat the disorder. Additionally, SWSD can resolve with a consistent night shift schedule or by moving to a daytime shift. Some recommended lifestyle changes include keeping a regular sleep schedule, wearing sunglasses when leaving work to minimize sun exposure, taking naps when possible, limiting caffeine intake before bedtime, maintaining a healthy diet, and creating a dark and quiet environment for sleeping.

Diagnosis and treatment
Shift work sleep disorder (SWSD) is a condition that primarily affects people who work night, early morning, or rotating shifts. It is characterised by excessive sleepiness, lack of refreshing sleep, and drowsiness. These symptoms can affect both work and leisure time.
To receive a diagnosis of SWSD, patients should report symptoms for at least one month, although some sources suggest three months, despite attempts to get enough sleep each day. Doctors will likely ask a series of questions about sleep patterns and disturbances, the type of shift worked, medical history, and any current medications. They may also ask for a sleep diary covering at least seven days. Additional tests may be carried out to rule out other underlying illnesses or conditions.
There are ways to lessen the effects of SWSD, including various lifestyle changes. These include keeping a regular sleep schedule, taking 48 hours off after a series of shifts, wearing sunglasses when leaving work to minimise sun exposure, taking naps when possible, limiting caffeine intake, maintaining a healthy diet, using heavy shades to create a dark environment, and reducing noise and household chores during sleep hours.
If behavioural changes are unsuccessful, doctors can prescribe sleep aids and/or stimulants. A visit to a sleep clinic may also be useful.

Health risks and negative consequences
Shift work sleep disorder (SWSD) is a chronic condition that can have serious health risks and negative consequences if left untreated. It primarily affects people who work outside the hours of 6 am and 7 pm, including fixed and rotating shifts. The disorder is characterised by excessive sleepiness, lack of refreshing sleep, and drowsiness, which can impact both work and leisure time. Here are some of the potential health risks and negative consequences associated with SWSD:
Sleep Deprivation and Insomnia: SWSD can lead to significant sleep loss, with the average person losing one to four hours of sleep per night. This can result in insomnia, which is characterised by persistent difficulty with sleep onset, duration, and quality. Insomnia can have a negative impact on overall health and well-being, leading to fatigue, reduced alertness, and impaired concentration.
Accident Risk: The fatigue and reduced alertness associated with SWSD can increase the risk of accidents, both in the workplace and during the commute. Individuals with SWSD are at a higher risk of committing errors or being involved in workplace accidents, and they are also more susceptible to vehicular accidents due to drowsy driving.
Health Problems: Sleep loss and chronic sleep deprivation can worsen underlying health issues, including gastrointestinal, metabolic, reproductive, and cardiovascular problems. SWSD has also been linked to an increased risk of cancer. Older workers and female workers are at a higher risk of experiencing sleep deprivation and its associated health consequences.
Mood and Mental Health Issues: SWSD can cause mood problems, including irritability, impatience, and difficulty coping with problems or conflicts. It can lead to social withdrawal and a decreased desire for social engagement with coworkers, friends, and family members. People with SWSD are at a higher risk of developing depression compared to those without the disorder.
Substance Abuse and Poor Diet: Many individuals with SWSD may turn to self-medication with alcohol or drugs to improve their sleep. Studies have also linked SWSD with unhealthy eating habits, which can further contribute to overall health deterioration.
It is important to note that not everyone who works non-traditional shifts will experience SWSD, and some individuals may naturally adapt to these schedules without developing the disorder. However, for those who do experience SWSD, seeking treatment and making lifestyle changes are crucial for managing the condition and preventing potential health risks and negative consequences.

Lifestyle changes and sleep aids
Shift work sleep disorder (SWSD) is a chronic condition that affects people who work non-traditional hours, such as night, early morning, split, or rotating shifts. It is caused by a disruption to the body's internal circadian rhythm, resulting in insomnia, excessive sleepiness, and sleep disturbances. While there is no cure for SWSD, the condition can be managed through lifestyle changes and sleep aids.
Lifestyle Changes
- Maintaining a regular sleep schedule, even on days off, is crucial for those with SWSD. This includes taking 48 hours off after a series of shifts to recover.
- Avoiding exposure to sunlight on the way home from work and wearing sunglasses can help prevent activating the "daytime" clock.
- Taking naps when possible can help reduce sleep deprivation.
- Limiting caffeine intake, especially after a certain time of day, is important to promote better sleep.
- A healthy diet rich in fruits and vegetables can improve overall health and sleep quality.
- Creating a dark environment with heavy shades or curtains can improve sleep quality during the day.
- Reducing noise and distractions from family or roommates can help create a peaceful sleep environment.
- Avoiding a long commute can help maximize sleep time and reduce drowsiness.
- Maintaining nightly rituals before bed, even during the daytime, can signal to the body that it's time to wind down.
- Limiting the number of night shifts in a row and avoiding frequently rotating shifts can help reduce sleep disruption.
- Keeping the workplace brightly lit can promote alertness during night shifts.
Sleep Aids
- Melatonin supplements are considered safe and can improve sleep quality.
- Hypnotics and sedatives, such as zolpidem (Ambien) and eszopiclone (Lunesta), can be prescribed for short-term use.
- Modafinil (Provigil) is a wake-promoting drug that can improve sleep and reduce morning sleepiness.
- Stimulant medications, such as Nuvigil, can help relieve sleepiness during work hours.
- Sleep aids like Sonata and certain antidepressants or benzodiazepines may also be prescribed to aid with falling asleep.
