The sun: what almost no one tells you
Putting on sun cream isn't the hard part. The hard part is using enough of it, and putting it on again.
Almost everyone buys the right cream and uses it wrong. It's nobody's fault: the instructions come in tiny print and talk about milligrams per square centimetre.
Translated: an adult body needs around six tablespoons of cream. That's a lot more than most of us put on. Use half that, and an SPF 50 behaves like an SPF 20.
Second point: you reapply it. Every two hours, and always after a swim, even if the bottle says water-resistant. Resistant doesn't mean permanent.
Third, and this is the one that changes things most: clothing protects better than any cream. A sarong thrown over your shoulders covers your back without forcing you out of the sun. A dry, tightly woven t-shirt blocks more than a high factor applied badly, and you never have to reapply it.
And the midday-to-four window is still the midday-to-four window. Shade during those hours isn't giving up on the day; it's what lets you last through the rest of it.
