SUMMER has hit early with Queenslanders enjoying a weekend heatwave.
But while 30-degree days are perfect for getting outdoors and soaking up a few rays, keeping us safe in the sun is the focus of scientists at Queensland University of Technology.
Researchers are trialling a hi-tech UV-sensitive patch that changes colour when it comes time to reapply sunscreen. The innovation could be a lifesaver.
Queensland has a melanoma incidence rate of 71 cases per 100,000 people, vastly exceeding rates nationally and internationally.
“Despite doing their best to stay sun safe and sunburn-free, people get either the concentration or the timing wrong resulting in a damaging dose of ultraviolet radiation,” said Dr Elke Hacker, of QUT’s Institute of Health and Biomedical Innovation.
Sunscreen when applied at the correct concentration (2mg/cm2) is effective at blocking the harmful effects of ultraviolet radiation.
But the researchers found many people apply less than half the needed amount.
Dr Hacker is leading the pilot study looking at the useability of the newly developed indicator.
“As part of our study we are looking for Brisbane-based volunteers to test a patch before we undertake a larger trial to determine if it can reduce the incidence of sunburn,” Dr Hacker said.
Participants in the research study will be asked to test the patch for a seven-day period and attend two focus group sessions at the start and end of the study.
Katie Clift, from Cancer Council Queensland, said it was very important that the patches were rigorously tested and proven effective – “to ensure consumers aren’t given false confidence that they’re protected when they may not be”.
“We look forward to seeing the results of this innovative research,” Ms Clift said.
“Our climate and demographics make us uniquely vulnerable to skin cancer, necessitating ongoing vigilance in sun protection.”
Cancer Council Queensland advises Queenslanders not to rely on sunscreen alone for sun protection but adhere to the Slip Slop Slap message.
The warm and sunny spring conditions in Queensland are expected to continue until a cold front moves through the southern parts of the state on Monday.
By Tuesday Brisbane temperatures are forecast to fall back down to the mid-20s.
