Police & Emergency Services Health
Health advice for police officers, PCSOs, and emergency service workers on rotating shift patterns.
UK police officers typically work a 4-on-4-off pattern, rotating between days and nights. It's one of the most disruptive patterns for your body clock — just as you adjust to nights, you flip back to days. Add in the physical demands, high-stress incidents, and the need to maintain operational fitness, and looking after your health becomes critical. This page is built for officers and emergency service workers.
Common Challenges
- 4-on-4-off rotations flip between days and nights, preventing circadian adaptation
- The transition from night shifts back to days is the hardest period for recovery
- Operational fitness standards require consistent training despite irregular hours
- High-adrenaline incidents make it difficult to wind down and sleep after shifts
- Canteen food and meal deals are often the only options during shifts
- Mental health impact of traumatic incidents compounds physical fatigue
Quick Tips
On the transition day from nights back to days, take a short nap (90 minutes) after your last night shift, then force yourself to stay up until a normal bedtime
Use the anchor sleep method — keep a consistent 4-hour sleep block (e.g. 23:00–03:00) regardless of your shift pattern
Train on your days off, not before or after shifts. Your body needs the recovery time
Prep meals in bulk on your 4 days off. You've got the time — use it
If you attend a traumatic incident, talk to someone. The Police Federation and Oscar Kilo offer confidential support
