This document discusses shift work sleep disorder (SWSD) and jobs that can negatively impact sleep. It notes that many modern jobs have the potential to disrupt sleep and cause issues like stress, fatigue, depression, and insomnia. The document will identify solutions over the next few weeks for surviving jobs that contribute to SWSD, such as air traffic controllers, pilots, nurses, doctors, and others who work shifts or long hours. The overall goal is to provide recommendations for maintaining healthy sleep schedules despite challenging work conditions.
