Why is the Australian sun so dangerous?

As the ozone layer depletes, the atmosphere loses its protective filter and more of the dangerous UV radiation reaches the surface of our planet. … The problem with Australia is that the continent receives higher UV radiation levels than Europe.

Which country has the harshest sun?

New Zealand now has the highest rate of melanoma skin cancer in the world – eclipsing Australia as the most dangerous place to be exposed to the sun. New research published in the Journal of Investigative Dermatology has found New Zealand has 50 cases of melanoma per 100,000 people, compared with Australia’s 48.

Why is Australia skin cancer rate so high?

Australia has one of the highest rates of skin cancer in the world. Anyone can be at risk of developing skin cancer, though the risk increases as you get older. The majority of skin cancers in Australia are caused by exposure to UV radiation in sunlight.

What part of the sun is the most dangerous?

Lastly, UVC radiation, which has the shortest wavelengths between 290 and 100 nm, and hence the highest energy, is the most harmful of the three radiations. Luckily this radiation is blocked almost completely by the ozone layer.

Why is the sun so dangerous?

The sun radiates light to the earth, and part of that light consists of invisible UV rays. When these rays reach the skin, they cause tanning, burning, and other skin damage. UVA rays cause skin aging and wrinkling and contribute to skin cancer, such as melanoma (the most dangerous form of skin cancer).

Why is Australia’s sun so strong?

During summer, the Earth’s orbit brings Australia closer to the sun (as compared to Europe during its summer), resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans.

Is the sun stronger in New Zealand than Australia?

In terms of energy, the sun is stronger in Australia due to it being closer to the equator. But in terms of UV light which causes sunburn, it is stronger in New Zealand due to a thinner ozone layer, and less pollution (clearer air).

What is the biggest cancer killer in Australia?

In 2020, lung cancer is estimated to be the leading cause of cancer related death, followed by colorectal cancer. 5-year relative survival was 69% for all cancers combined in 2012–2016.

Why is there no ozone layer in Australia?

The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).

Which cancer kills the most in Australia?

As of 2018, lung cancer remains the leading cause of cancer death in Australia. According to Cancer Australia, it is the fifth most common diagnosed cancer in Australia behind breast, prostate, colorectal and skin cancers.

What is the safest time to be in the sun?

To protect against damage from the sun’s rays, it is important to avoid the sun between 10 a.m. and 4 p.m., when the sun’s rays are strongest; to wear protective clothing; and to use a sunscreen with an SPF of 15 or higher.

Is the sun stronger now than before?

According to Scripps Atmospheric Scientist Ray Weiss the answer is no, even though it feels that way. He says it’s not that the sun is stronger, but rather the ozone layer is thinner meaning more UV rays are coming through.

What time is Sun strongest?

Time of day: UV rays are strongest in the middle of the day, between 10 am and 4 pm. Season of the year: UV rays are stronger during spring and summer months. This is less of a factor near the equator.

What are the 5 S’s for sun safety?

A good rule of thumb for skin cancer prevention is following the 5 S’s: “Slip, Slop, Slap, Seek, Slide.” The campaign, a cornerstone of Nevada Cancer Coalition’s Sun Smart Nevada program, encourages people to: Slip on a long-sleeved shirt or sun protective clothing.

Can you kill the sun?

There are only two (currently) conceivable ways we might destroy the sun: Remove enough hydrogen from the sun so that there is no longer enough gravitational pressure to generate fusion add its core. Add enough material to the sun so that it explodes in a supernova.

Summary: New research suggests that the timing of exposure to UV rays — early in the morning or later in the afternoon — can influence the onset of skin cancer.
