Brief Summary
-----------------
Studies have shown that schedules that most disrupt the normal circadian rhythm have the most harmful consequences. Firefighters positive for a sleep disorder have a higher risk of depression and anxiety; they report more traffic accidents, falling asleep during driving, and worth health felt.

This activity is responsible of a worth quality of sleep that could induce a lower effectiveness of emergency response. The consequences of this schedules on sleep and health of French firemen have never been studied.
