Sunburn – skin that is red, hot and sore – may result from too much exposure to the sun. The most obvious thing to do is to get out of the sun, but it is also valuable to cool the skin using a damp towel or in the shower, and by applying aftersun products. Dehydration is a real risk, and can be averted by drinking plenty of water. Taking painkillers such as ibuprofen and paracetamol can ease any discomfort. Blisters and peeling skin should be left well alone, but someone who is feeling very unwell should seek medical attention.

Sun safety

Sunscreen is a must, and customers should be advised to use products with a high sun protection factor (SPF) and a UVA star rating of at least four. It can be tempting to use sunscreens that have been kept from previous holidays, but counsel customers on the importance of checking the expiry date and discarding anything that smells or feels funny or has been open for more than a couple of years. Check that people understand how much to apply: for adults, this is around two tablespoons to cover the entire body including the face, neck and ears, as well as the head for individuals with thinning or no hair. Sunscreen should be reapplied liberally and frequently, including after being in water, towel drying or sweating, and should be applied twice before going outside if someone is going to be out in the sun for long enough that they might burn. Other protective measures that should be taken include covering up with suitable clothing and sunglasses, and spending time in the shade, particularly during the middle of the day when the sun is at its strongest.
