Shift Work Sleep Disorder: Causes and Symptoms

Shift Work Sleep Disorder (SWSD) is a type of circadian rhythm sleep disorder that affects individuals who work nontraditional hours, such as overnight, early morning, or rotating shifts, instead of the conventional 9 a.m. to 5 p.m. schedule. Circadian rhythms are the body’s natural processes that regulate physical, mental, and behavioral changes within a 24-hour cycle, primarily responding to light and dark cues. Shift work disrupts these rhythms, leading to difficulties in maintaining regular sleep patterns and resulting in various health and performance issues.

Causes of Shift Work Sleep Disorder (SWSD)

Regular Work Hours

Shifts that aren’t the norm, like night shifts, rotating shifts, or early morning shifts, mess up the body’s normal circadian rhythm.

Circadian Rhythm Disruption

This happens when the body’s internal clock is not in sync with the outside world, making it hard to maintain normal sleep-wake cycles.

Environmental Factors

Being around light at night and dark during the day can make the body’s internal clock even less accurate.

Social Factors

Problems with family and social events can make it harder to sleep and make you feel more stressed.

Symptoms of Shift Work Sleep Disorder (SWSD)

Insomnia 

When you have trouble going or staying asleep, which makes your sleep less restful.

Extraordinary Sleepiness

Feeling sleepy and tired all the time, especially during work shifts.

Problems with Focusing

Less alertness and worse cognitive function, which affect safety and job success.

Mood changes

Physical symptoms

SWSD can significantly impact overall health, job performance, and quality of life, making it essential to address and manage it effectively.
