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.

Mechanisms: sleep, timing, and appetite

Short sleep and circadian disruption are associated with altered hunger hormones and more opportunistic eating — especially ultra-processed snacks when tired. That is biology interacting with environment, not moral failure.

Food environment on site

Vending-heavy sites tilt choices. Where you can, bring balanced meals with protein and fibre; where you cannot, even predictable meal times help regulate appetite signals.

Sustainable habits over perfection

ShiftCoach’s meal timing features are built for irregular clocks — small repeatable wins beat crash diets that collapse on overtime weeks.

Frequently asked questions

Is weight gain inevitable on nights?
No. Risk rises on average in population studies, but individual trajectories vary. Sleep improvement, meal timing, movement, and stress management all influence outcomes — as does access to healthy food at work, which is often a systems issue, not willpower.
