It’s well known that only mad dogs and English(people) go out in the midday sun. Those who live in hot countries learned long ago to seek shade when the day is at its hottest. Traditional wisdom did not need to wait for scientists to warn that exposing skin to the blazing sun can cause skin cancer. Go see how the Tuareg people dress to deal with the desert heat. Only the English insist on lying on their back in full sun, until their skin has turned dark purple. Seek shade. Be sensible. Stay safe.
