Internal Medicine

Shift work sleep disorder (SWSD) is a circadian rhythm condition that causes excessive fatigue, insomnia, and difficulty concentrating in people who work non-traditional hours. Left untreated, it can impact heart health, mood, and job performance.

Common treatments include:

Improving sleep hygiene (dark, quiet sleep environment)
Light therapy to reset your internal clock
Melatonin or prescription medications
Strategic napping and caffeine timing

If you're constantly exhausted, struggling to sleep, or unsure whether your symptoms point to SWSD or something else, don't guess. Understanding the root cause is the first step to feeling better—and the sooner you identify it, the sooner you can act. Take a free, instant, online symptom check to clarify what may be going on and confidently plan your next steps.
