Learn how and why you should protect yourself and your family from UV exposure
UV damage and impact
UV radiation can cause sunburn. Repeated sunburns can cause lasting skin damage. People exposed to UV radiation over many years can suffer irreparable damage, such as:
- skin cancer – severe UV damage to skin cells can result in red, scaly skin lesions (sometimes known as 'sunspots'). Over time, skin cancers may develop from the damaged cells. The face and scalp are the most common affected areas.
- eye damage – UV can harm unprotected eyes over many years. It can cause growth of tissue and blood vessels in the inner corners of the eyes and cataracts in the eye's lens.
- premature ageing – UV exposure can destroy the elasticity that gives skin its youthful appearance. The face, forearms and backs of the hands are the most common affected areas.
We need vitamin D, however, for good health and to keep bones and muscles strong. Sensible sun protection does not put people at risk of vitamin D deficiency.
5 ways to protect against UV
Cancer Council Australia recommends 5 steps to protect against UV damage when the UV Index is 3 or above:
- Slip on sun-protective clothing – clothing can be a great barrier between the sun's UV and your skin.
- Slop on sunscreen – sunscreen should be considered the last line of defence. No sunscreen blocks 100% of UV radiation.
- Slap on a hat – look for a hat with a tight weave and broad brim that provides good shade for your face, head, neck and ears.
- Seek shade – either natural, built or portable.
- Slide on sunglasses – choose a close-fitting, wrap-around style of sunglasses.
