Simply put, occupational health is health in the workplace. It’s a two-way relationship – the effect of work on health, and the effect of health on work.
The effect of work on health would be things like hand-arm vibration syndrome (HAVS), noise-induced hearing loss (NIHL), asthma, eczema and dermatitis.
The effect of health on work includes things like diabetes, musculoskeletal conditions and epilepsy.
