Schedule outdoor activities to avoid the hours when the sun is at its strongest – when directly overhead. Doing this can help to minimise exposure. Where possible, rearrange your day’s schedule to spend time outdoors when the sun is lower in the sky – early mornings and late afternoons (11am-3pm).

Excerpt: Don’t spend any longer in the sun than you would without sunscreen. Sunscreen should not be used as an excuse to stay out in the sun. Instead, it offers protection when exposure is unavoidable. The summer sun is most damaging to your skin in the middle of the day. Spend time in the shade between 11am and 3pm, under umbrellas, trees, canopies or indoors.
