Sun Safety Introduction The sun’s ultraviolet (UV) radiation is the major cause of skin cancer. Australia has some of the highest UV levels in the world: in fact UV radiation is strong enough to cause sunburn in just 11 minutes on a fine January day In Australia, every year: skin cancers account for 80% of all newly diagnosed cancers. two in three Australians will be diagnosed with skin cancer by the time they are 70. Australia has one of the highest incidences of skin cancer in the world, at nearly four times the rates in Canada, the US and the UK. melanoma is the most common cancer in people aged 15-44 years GPs in Australia have over 1 million patient consultations per year for skin cancer. http://www.sunsmart.com.au/uv-sun-protection watch advertisement.

What is UV? Ultraviolet (UV) radiation is a type of radiation that is produced by the sun and some artificial sources, such as solariums. The sun’s UV radiation is the major cause of sunburn, premature ageing, eye damage and skin damage leading to skin cancer. However, it is also the best natural source of vitamin D. Vitamin D is important for bone health because it helps absorb calcium (milk, yogurt, cheese) It also plays a role in: Supporting growth and maintenance of the skeleton Regulating calcium levels in the blood

The UV Index The World Health Organization's Global Solar UV index measures levels of UV radiation on a scale from 0 (Low) to 11+ (Extreme). Sun Smart recommends the use of sun protection whenever the UV levels are 3 (Moderate) or higher. There is a huge variation in UV levels across Australia and UV levels can vary across the day. The UV level is affected by a number of factors including the time of day, time of year, cloud cover, altitude, proximity to the equator, scattering and reflection. UV cannot be seen or felt. It is not like the sun’s light which we see, or the sun’s warmth (infrared radiation) which we feel. Because we can’t sense UV radiation, we won’t know that it has damaged our skin until it is already too late.
