People who work outside all day for many years, like gardeners or road workers, are much more likely to get a type of skin cancer called SCC than people who work inside, because of all the sun they’re exposed to.

Even among people doing the same outdoor job, some get way more sun than others—so some are much more likely to get skin cancer, depending on how they work and whether they use shade or sunscreen.

The safety limit for sun exposure at work is too low—many outdoor workers in Lisbon get 3–4 times more sun in a day than the current safety rule allows.

Wearing a sun exposure meter on the arm gives a much better idea of how much sun a worker gets than guessing based on their job title, making it a better tool to protect them from skin cancer.

Being in the sun a lot over your whole life — not just on vacations — makes you much more likely to get SCC, a type of skin cancer.
