Can you tan at 9am?
Can you get a tan at 9am ? Either time will work, but for humans, it seems that early morning tanning is better than late afternoon. This is because of the body’s circadian rhythms and how they react to sun exposure.
Why is Australian 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.
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).
Is the sun stronger in New Zealand than Australia?
Answer; the sun strength in the Southern Hemisphere is far stronger than our Northern neighbors. There are three scientific reasons for this: there is less ozone in New Zealand to block UV rays. the earth’s orbit takes us closer to the sun during the southern summer than during the northern summer.
Is early morning sun harmful?

Does morning sun damage skin?
Exposure to ultraviolet (UV) radiation in the morning may be less harmful to your skin than tanning in the afternoon, new research suggests.
What does UV Index 13 mean?
UVI 1-2 is low, which generally means it’s safe to be outdoors unprotected. To illustrate, today in Cairns the period when sun protection was needed was 8.10am to 4.10 pm, with a UV Index peak of 13 and extreme levels between about 10am and 2pm.

What is a bad UV index?
A UV Index reading of 0 to 2 means low danger from the sun’s UV rays for the average person. 3 to 5 means a moderate risk of harm from unprotected sun exposure. 6 to 7 means a high risk of harm.
