Be Sun Smart
You cannot feel or see UV (Ultraviolet radiation). We can see the sun's light and we can feel the sun's warmth (the infrared radiation). Our senses don't pick up on UV radiation and this is why it is so damaging.
Right across Australia this UV radiation varies, it being determined by the time of day, time of year, the weather including cloud cover, how close to the equator the position is and other considerable scientific factors.
