Hi! As heatwave scorches Europe, the second problem I’m a little afraid of (especially as someone without any melanin in my skin) is the sun. I’ve seen someone mentioning a sun shirt but trying to find real information online is very confusing, especially with EU in mind ( I see US has something called UPF) and if you are not looking for ads. Maybe someone knows something about it?
Heat and UV are correlated but weakly. It’s entirely possible that an early spring day with cool temperature and light breeze has a higher UV levels than a cloudy day with 35°.
You don’t need specific SPF clothing to get protection.
This has a good discussion about spf clothing. https://www.nytimes.com/wirecutter/reviews/best-sun-protection-clothing/
My personal preference is to seek shade and wear sunscreen when it’s intolerably warm, rather than to add tight weave clothing, but to each their own.
i thought UV rays generally are strongest when the sun is directly overhead, like at noon in june (in the northern hemisphere)
