One of my friends applies sunscreen to her skin even when she is at home all the day! She thinks there are UV rays even inside our homes since most the apartment windows are not UV blocking.

How serious should we take her?

Does she wear a tin foil hat too?

I also HAVE to use suncreen inside. You can certainly still burn inside, there are 3 types of UV rays and one at least goes through glass, car windows and inside houses, unless they are tinted.

Also people forget that although glass cuts some of the rays, usually in hot climes the windows are open, flyscreen cuts nothing.

Tinting, blockout, sunblock are a unfortunate part of life for me, however the bonus is I look a lot younger than aussies the same age

But are you lithe and trim? Or are you a true Tesco middle-aged type with collapsed arches and scuffed heels?

I bet you're a hoot at parties too.

Something tells me she is. Old Jad's alright I reckon. Maybe inclined to worry...I always imagine her as a younger, nicer Mrs Bouquet (in terms of being English that is, not for being a snob) and spending all her life in Tesco. Not a true Little Englander, even if some of her tastes are Little Englander.

"Most glass absorbs the short wavelength UV (UV-C 190 - 280 nm and UV-B
280 - 320 nm), but transmits the longer UV-A (320 - 400 nm) radiation.
The UV-B is the erythemal region that causes sunburn and skin cancer,
but the UV-A can also cause sunburn and tanning".

Do what the Missus does - uses moisturiser after morning shower with inbuilt block.

UV-B doesn't go through glass. UV-A does.

UV like all light rays travels in straight lines so if you are inside but in the sun then UV-A is still hitting you. If you are out of the sun then you are being hit by reflections. The amount of energy being reflected will depend on the surface but for most things will be small. If you can see the sun reflecting off the surface of a pool then it'll be high but not as high as in direct light.

Personally unless you are inside in direct sunlight then I wouldn't bother with sunscreen.

Even when you are not under direct sunlight passing through windows? Like when you are sitting on the dining table having lunch while you are 5 meters away from the windows?

I always thought it was necessary when you are near the windows.


P.S.

Thank you MartinLuther. You fade my concern since we have never used sunscreen inside home.

Can't answer your question but I will award you the prize of "Poster who starts the most bizarre threads. 2010".... even though its still early in the year I can't see you being caught.

And the bit I found is that A can cause burning. But it is the B which is particularly damaging.

In her tin foil hat and sunscreen.....

Guaranteed to be the main topic of conversation rather than the centre of it

I guess it depends on how your house is built and how you live in it (not as daft as it appears). We don't get any direct sunlight in our house, the overhangs are wide enough all round to prevent it. However if you're in a house with no overhang and no nearby trees and you have desks, tables etc close to windows that you're sat at working during the day then there's far more likelihood of burning inside.

No way!! I integrated and am now a real aussie beauty , barrel shaped, beer belly, bare feet are black and heels thick with an inch of dry skin, skin like the hide of an old croc, baggy cotton shorts and a tank top, bare feet, and in winter I go to work in flannel pj's

Actually I became really serious about skin cancer, rays etc after a couple of y close calls with the deadly type of 'innocent' looking moles. On fair people they can show up as nothing more than a tiny lump of white skin, not even mole looking. People are looking for black, brown and red moles, not a tiny bit of raised white skin

You do all the sunsmart stuff outside, then wonder 'why" did this happen, of course your totally ignoring the radiation thats getting you inside, in the car, the 5 mins in the garden, others on here have said they can get burnt in qld pegging out the washing, thats a 10 minute job.

Don't forget to apply before you have a bath, those pesky rays get trapped in the bathwater (not forgetting they have spent all that time unprotected in a dam).

The concentrations are off the scale by the time you dip your toe in.

A full scuba suit is the only way to be sure.

HTH!

MartinLuther

That's what happens when you drive for a long time. The arm in the sun starts burning and the other is okay.
