What is sunburn?
What causes sunburn?
Sunburn is caused by an excess of UV radiation as a result of over-exposure to sunlight, in other words, exposing your skin to the sun for too long.
How to prevent sunburn?
- Keep out of the sun during the hottest times of the day (usually 11h00 - 15h00)
- Limit the amount of exposure to the sun, especially in children and people with fair and sensitive skin
- Always wear a hat and protective clothing when exposed to the sun, particularly when participating in any outdoor sport activities
- Use a sunscreen on your body and face that contains a with high SPF (sun protection factor) and reapply often after swimming, sweating or towel-drying
What are the symptoms of sunburn?
The symptoms of sunburn demonstrate red or bright, pink skin that is painful, inflamed and hot to the touch. Sunburned skin may blister, peel or even become 2nd degree burns.
Dangers of over exposure to UV Radiation from the Sun
- An excess of UV radiation can be life-threatening in extreme cases. Primarily non-malignant skin tumours can develop from sunburn, which may, in rare cases, eventually become malignant.
- Solar keratosis or sun damage, where the skin becomes hard white and produces crusts and hard flaky lesions are another risk of sunburn. Solar keratoses are pre-cancerous (pre-malignant), which means they have a potential to turn into skin cancers called squamous cell carcinomas. Squamous cell carcinomas can be fatal in some cases. The exact risk of a solar keratosis turning into a skin cancer is not known.
- Sunburn and the increase in melanin production are triggered by direct DNA damage. When the skin cells' DNA is overly damaged by UV radiation, type I cell-death is triggered and the skin is replaced.
