IF you’re feeling a bit fragile and burnt from too much sunbathing, staying inside probably seems like the sensible option.
But can you still catch the sun’s rays through a window and can you enjoy the benefits of the sunshine while you’re stuck at work? Here’s the lowdown…

Can you get a suntan through a window?
Surprisingly, you CAN get a suntan through a window!
Most panes of glass absorb around 97 per cent of the sun’s UVB rays – the ones which cause sunburn and some skin cancers.
While the glass will absorb 37 per cent of the less harmful UVA radiation, expert Luis Villazon told Science Focus.
This is the equivalent to an SPF30 sunscreen – meaning you could still get tanned, freckled and even burnt if you sat in a sunny spot for long enough.
However, car windscreens are a little different – because they have a plastic layer between the two layers of glass, blocking all of the UVB and 80 per cent of the UVA.
This makes tanning in the car extremely unlikely. So don’t expect to get bronzed next time you have a long journey.
