The hazard
A tired worker reacts slower, misses hazards and makes more mistakes, often without noticing. Fatigue builds up from long shifts, night work, heat, hard physical work, stress and too many short nights in a row. Around equipment, heights or traffic, one slow reaction can be enough to get someone hurt.
The action
Only sleep can make up for lost sleep, and the loss adds up over several short nights. Keep a regular sleep schedule, make your room dark, quiet and cool, and put the phone away before bed. If you work nights, block out daylight and protect your sleep time like an appointment. Caffeine can hide tiredness for a while, but it does not replace sleep.
