Stress

Occasional stress is harmless; chronic unrelenting stress is not. High perceived stress associates with ~20% higher mortality, sustained 55+ hour work weeks raise stroke risk by a third (WHO now counts overwork as an occupational hazard), and what protects you is recovery — people with deliberate wind-down habits buffer most of the damage.

The research

  • Kivimäki & Steptoe, Nat Rev Cardiol 2018 — stress and CVD mechanisms
  • Pega et al. (WHO/ILO), Environ Int 2021 — 55+h weeks: +35% stroke, +17% IHD
  • Nielsen et al., J Aging Res 2016 — perceived stress and mortality
