Consider this your SPF bible.
Is physical SPF more effective than chemical" What does ?reef safe? even mean" As we stare down the barrel of another long, hot Australian summer, the conversation around sun protection has never been more complicated. We ask the experts to help sort the fact from fiction. 
 

 
When is it safe to go in the sun" 
Ask most Australians and they?ll tell you the same thing: a day at the beach is a day well spent. For Heather Walker, Chair of the Skin Cancer Committee at the Cancer Council, one of her biggest challenges is educating the public that it?s UV radiation that causes sunburn and skin cancer, not heat ? meaning, you can get just as sunburnt on a cloudy day. When the UV is three or higher, you need to take precautions. ?UV starts to peak across the country around mid-August,? Walker explains. ?In some states, like Queensland, it?s high all year round.? The Cancer Council?s SunSpart app is a free tool to accurately gauge UV levels. According to Walker, there is a ?guilt-free? time to enjoy the sun. ?UV tends to peak in the middle of the day, [but] heat tends to peak well into the afternoon.? Late afternoon, early evening ? i.e. the hottest part of the day ? is when you?re least likely to get burnt. ?If it?s a clear day and the heat has continued to rise up until 6pm in the evening  ? actually, the UV is down and you don?t need to worry about getting sunburnt.?
