High UV is high UV, no matter the hour, and no matter the cloud cover - it may have dissipated some from earlier in the day, but still within the timeframe for using some sort of protection: e.g. ) http://www.bom.gov.au/vic/uv/melbourne.shtml
UV forecast for the next several days is listed as 'Extreme'
Better to cover as much as possible than rely on sunscreen, too, if you'll be out for more than a short stint
Yep I've been vigorously applying sunscreen as all the TV commercials have been telling me since I was a kid...But I just got diagnosed with a major vitamin d deficiency that is causing my tiredness, poor immune system, bone aches and muscles and the list goes on...ever since exposing myself to the sun without sunscreen (sunscreen stops the body absorbing vitamin d from the sun) and taking the supplements 3 times a day I am a completely different person. Need to find a balance between protecting yourself from UV rays and still absorbing some Vitamin D...
I now check the bom site before riding the bike home for the current UV level. if it is high, i put sunscreen on. If it isn't, I let it go.
The goal posts on what's considered low changed, and it has become common (overly tested even) blood work-up these days...
Paradoxically, with one of the highest skin cancer rates in the world, Australians also have high levels of Vit D deficiency. Victoria, for example, is far enough south to make it a problem. The fairer you are, generally, the faster you'll make it, necessitating less sun exposure than those with dark skin. And through glass doesn't count. If people are worried about osteoporosis, stop sucking up calcium products until you also know what your vit D levels are like! It's also important for pain management and mental health. The list goes on and on...
There has been some interesting research out of ... I think Denmark?... on having TOO much vit D as well as too little. Bit confusing... but moderation, etc...
I'll be putting my sunscreen on before I ride home tonight.
