The sun produces different types of energy
- Visible light – which we can see as sunlight
- Infrared radiation – which we feel as heat
- UV radiation – which we cannot see or feel
It doesn’t matter how hot it is outside, being sun safe is all about the UV radiation level. UV radiation is often confused with infrared radiation.
But there are important differences:
- The temperature does not affect UV radiation levels.
- If the UV level is over 3, it can damage your skin.
- We can’t see or feel UV radiation and it can still be high (and cause damage) on an overcast, cloudy, windy, or cool day – not just scorching ones.
Remember:
- Overexposure to UV is the main cause of skin cancer. The skin can be damaged in as little as 15 minutes on a fine January day.
- Skin cancer is Australia's most prevalent cancer, but it is also one of the most preventable.
- All sunscreens available in Australia are approved by the TGA (Therapeutic Goods Association) and go through stringent tests, so find one that suits you.
- If you have any concerns or questions, please contact your doctor.
The UV Index is a tool you can use to protect yourself from UV radiation and is available through the SunSmart App.
The UV Index divides UV radiation levels into:
- Low (1-2)
- Moderate (3-5)
- High (6-7)
- Very high (8-10)
- Extreme (11 and above)
If the UV index is going to be above 3, you need to follow the Cancer Council’s advice.
Slip on covering clothing
Choose clothing that covers as much skin as possible, for example, collared shirts with long sleeves.
Slop on SPF 30 (or higher) broad-spectrum, water-resistant sunscreen
Apply a generous amount of sunscreen to clean, dry skin at least 20 minutes before you go outside. The average-sized adult needs a teaspoon of sunscreen for their head and neck, each limb, and the front and back of the body. Reapply every two hours or after swimming or excessive sweating.
Slap on a hat
Choose, a broad-brimmed, legionnaire or bucket style hat. Caps and visors do not provide enough protection.
Seek shade
Shade reduces UV radiation, but it can still reach you via reflection, so shade by itself won’t give you enough protection.
Slide on some sunglasses
Choose close-fitting wraparound sunglasses that meet the Australian Standard AS/NSZ 1067.
And finally:
Keep an eye on your skin
Did you know? At least 2 in 3 Australians will be diagnosed with skin cancer before the age of 70
Check your skin regularly for any new spots or changes in shape, colour, or size of existing spots. If you notice anything unusual, see your doctor as soon as possible. Most skin cancer can be successfully treated if it is found early.
