Singapore has been rightly focused on heat stress among outdoor workers. But, in doing so, we are overlooking a far more widespread and dangerous hazard – solar ultraviolet (UV) radiation.

According to the Singapore Cancer Registry, 4,128 skin cancer cases were diagnosed between 2019 and 2023. That is about 825 cases a year, or two or three new cases every day. More than 90 per cent are linked to UV exposure.
