Spending some time outdoors in the sun helps you stay healthy, but it’s also important to protect your skin from burning as this can increase your risk of skin cancers.
Our bodies use the UVB rays in sunlight to make vitamin D, which is important for bone health and reduces the risk of many illnesses, including cancer. Most people can get enough exposure to UVB rays by going outside regularly, without sunscreen on, for a few minutes during the middle of the day. The amount of sun exposure you need depends on your hair and skin type. But it’s important not to stay out long enough to let your skin redden or burn.
If you are going to be out in the sun for longer than a few minutes, use a sun cream that protects against both UVA and UVB rays, with a sun protection factor (SPF) of at least 15. You should wear loose, cotton clothes that cover your body, as well as a hat. Take extra care with children.
