Health & shift-work desk

Evidence-led writing for shift workers. We cite NHS, WHO, CDC/NIOSH, and occupational sleep medicine sources in each guide and avoid sensational claims.

Treat off days as sleep infrastructure

Four-day blocks can compress sleep debt; four days off look generous on paper but often fill with childcare, appointments, and travel. If you spend the entire off block in sleep catch-up mode, you return to work already depleted — pace recovery deliberately.

Social jet lag on days off

Sleeping in extremely late every off day then snapping to early starts mimics jet lag. A gentler slope — moving wake times by 60–90 minutes per day — is often easier on digestion and mood than a single heroic reset.

The day before you go back on

Bank sleep where you can, pre-pack meals, and avoid alcohol as a “wind down” shortcut. ShiftCoach reminders can be tuned to your block calendar so cues match your real return day, not a generic weekday.

Frequently asked questions

Should I flip to “day person” on every off block?
Some social alignment helps relationships, but violent flips can leave you more tired at work. Many 4-on-4-off crews benefit from a hybrid: partial day alignment on one off pair, stronger sleep protection before returning to block start.
