Despite the political debates, scientists are overwhelmingly confident that the fossil fuels we are putting in our atmosphere are causing global climate change. You’ve probably heard about the rising temperatures and falling pH of the ocean, but you might not be aware that climate change is also affecting us directly by changing the relationship between the sun and our skin.
In Australia in recent decades, anomalously warm months have occurred more often than anomalously cold months. Many heat-related records were broken in the summer of 2013-15 and in the year of 2013, including Australia’s hottest day, week, month and year averaged across Australia. Extreme summer temperatures during 2014- 15 were unlikely to have been caused by natural variability alone, and such temperatures are now five times more likely due to the enhanced greenhouse effect. Since 2001, the number of extreme heat records in Australia has outnumbered extreme cool records by almost 3 to 1 for daytime maximum temperatures and almost 5 to 1 for night-time minimum temperatures. Heat waves have increased in duration, frequency, and intensity in many parts of the country.
Scientists have found that elevated temperatures may also increase the risk of skin cancers, so the combined effects of climate change spell disaster for our skin. “Statistics show one in three Australian’s will develop skin cancer each year, and one person dies nearly every hour in this country from melanoma,”
Skin cancers occur because UV rays induce changes at the DNA level. While most cells that are damaged undergo programmed cell death, called apoptosis, sometimes the changes disrupt this innate protective mechanism, leading to cells whose growth goes unchecked. They continue to multiply when they shouldn’t, creating tumors that can grow and spread if not caught quickly enough. Melanoma is by far the worst type of skin cancer. Though it accounts for less than 5 percent of cases, it is responsible for three-quarters of skin cancer related deaths. More than 60,000 people worldwide die from melanoma every year.
Sun damage is one of the most prominent signs of ageing. Let’s face it, we all care about ageing! Billions of dollars are spent every year trying to counteract the sun’s negative effects. In the dermis, UV radiation breaks down the collagen that gives skin healthy elasticity. Over time, the loss of collagen leads to wrinkles and sagging skin.
The Key is to protect your skin from sun damage,
“UV exposure increases by about 33 percent for every 20 percent ozone layer loss and this means UV protection is absolutely crucial here in Sydney Australia,” says Jacqueline who is the Owner and senior therapist at http://inskinmedispa.com.au/ Neutral bay
“Being sun smart and limiting UV exposure when you’re young will dramatically improve the appearance of your skin over time. Simple measures can be taken to incorporate sun protection into your daily routine” she
recommends SPF 30 DNA Renewal by Dr Moy everyday.
The sun does not care what you are doing—gardening, walking on Balmoral beach or catching the ferry to Manly. The key is to stay protected, no matter the season.
How would the sun see you??!
