Some brief daily exposure to the summer sun helps us make vitamin D - but over exposure can be damaging. The sun produces visible and invisible light. Exposure to the invisible kind, ultraviolet A and ultraviolet B (UVA and UVB), is never safe and is responsible for skin cancers, cataracts, sunburn and premature skin ageing. While UV ray intensity tends to be highest in the summer, UV radiation can damage the body any time of year, even when it's cloudy.
The answer? For adults and children over 6 months old, experts recommend sunglasses, covering up with clothes, and a generous and regular application of sunscreen with a UVA and UVB sun protection factor (SPF) of at least 15. Babies under 6 months old should be kept out of direct sunlight.
