I’ve spent a lot of time researching this topic, and here’s what I found.
As a teacher, I don’t experience shift work firsthand. But my partner is a nurse. I’ve seen up close the impact of three-shift rotation on sleep and health. And teaching circadian rhythms in Earth science class has helped me understand just how hard a battle shift workers fight. [1]
Why Shift Work Damages Health
