I read on https://en.wikipedia.org/w/index.php?title=Sun_protective_clothing&oldid=930941768: A relatively new rating designation for sun protective textiles and clothing is UPF (Ultraviole...
Many outdoor clothing items advertise themselves with a UPF (Ultraviolet protection factor) of 30 or even 50. How does that compare with a normal cotton T-Shirt or a pair of jeans? Do I have to use...
My optometrist assures me that all polarized prescription lens will now also assure 100% UV protection. Is this true and if not how can I insure that I’m getting optimum UV protection from new pre...
TL;DR What are some reasonable (ie: safe, portable, reusable) ways to start a fire with a magnifying glass without damaging my eyes from staring at the focused sunlight? Background I recently st...
With sunblock it's relatively easy to know what to look for in terms of SPF, UV types etc, however with eco-friendly ones that aim to not put chemicals back in the ocean (used by surfers, swimmers,...
I am going to South East Asia for quite some time, and was looking for appropriate clothing. Quite a few websites recommend linen clothes, and almost all of them recommend UV protective gear due to...
When I am going swimming in the pool my skin gets tanned due to sun. Which SPF value is suitable for my purpose? Should I go for some specific ingredient, so that the lotion won't dissolve in wa...
What is SPF in sunscreen creams? I go to 2500m-4000m altitude. What should I use? And I've heard that SPF more than 55 is not for men. Does more SPF mean more sun protection?
Snow blindness, also known as photokeratitis, is predominately caused by the sun's reflection off of snow. If one is caught out in the wild, ill prepared for snow, what could one find in a tempera...
I need clothing for kayaking in the summer. I already have the "heavyweight" equipment - thick neoprene longjohn and a whitewater cag. But for places where I need less protection from cold and inju...
I normally use weather.gov and/or weather.com for weather forecasts. Neither provides UVI (or at least I can't find it). Also, I rarely go outdoors, so I don't have an intuitive sense of when I get...
From my experience, any tent gets hot when in plain sunlight, so I wouldn't stay in it (and can't imagine why anyone would) + I'd rather be outside my tent when the weather's nice. I don't really...
In addition to sunglasses, you can get clear safety glasses that claim "Blocks 99.9% of harmful UV rays". The advantage of clear safety glasses is that they can be worn both during dusk and after d...
I'll be backpacking Europe in the winter (snow and rain) and parts of my trip will be outdoors, such as hiking in Dolomites, Italy. For purposes of packing light and risk of losing expensive gear, ...
As I understand it, you can't combine multiple suncreens to combine their SPF values. This makes sense as they all work on the same concepts and your skin can't simply "hold more" because it's two...
I read in an old tourist guide (from the beginning of the 20th century) that during mountain walks on sunny days one should wear a red headscarf or a hat with red lining to avoid heat stroke, becau...
Will regular polarized sunglasses protect me against snow blindness? And if not what type of glasses/goggles will protect me?
My eyes are sensitive and tending towards cataracts. I'm told to avoid the Sun's UV, but many polarized sunspecs don't mention UV. I'd appreciate it if someone knows the answer.
I have noticed that most sunglasses leave quite a bit of gap on the side and only cover the "front" of the eyes. Does this give adequate UV protection, or are these types of sunglasses mostly "fash...
What level of UV protection is recommended for glacier travel? For example, I have sunglasses which says 40% UV layer. Will this be ok for glacier trekking, or do I need glasses with higher level o...
I have trouble seeing distant things and have myopia. Thus I prefer glasses with my prescription number (which is both cylindrical and spherical). I want protection from UV rays as I am going to sp...
I sat for 45 minutes last summer in the hot sun (100°F/38°C). I was pinned in on the bleachers so I wasn't able to get up and move. I could feel the sun burning through my pants. Now I have everyda...
Often, while hiking, my companions and I treat the very early/late sun as being less harmful (as far as skin cancer and UV radiation are concerned). For example, we might not apply sunscreen immedi...
When skiing, if the weather is good, I often come back with a better tan than if I have been at the beach. Obviously with altitude, there is less blocking of UV rays by the atmosphere. But how muc...
What should I look for in a suntan lotion for a nude camping trip? I don't know what to look for when it goes on the whole body. Are there any ingredients that I should watch out for?
All over the internet it says that sunscreen does not work all day, but does not say anything about why. Why does sunscreen not work all day? Does the matrials get destroyed by the UV rays? Or is...
Is it a viable practice to not wear a shirt, as long as you smear your body with sunscreen, if you plan to go hiking for hours (assuming reapplication)? Or is it advised to wear a shirt at all time...
I have a damaged pupil that stays partially dilated. And regular polarized sunglasses which I am wearing over the regular glasses aren't working better than my prescription sunglasses. I have a new...
With SPF 30 sunscreen, I am usually protected for an entire day and wont be getting more than a little darker. Now, I am getting low on SPF 30 cream but I have a large supply of SPF 15. Can I just ...
