Jallima1108, there does seem to be evidence that some Australians (especially fair skinned people) are now deficient in Vitamin D due to people becoming so much more careful of sun exposure but it does not appear to be related to the increase in allergies. We are all now so careful of children with sunscreen, sun protective clothing at the beach and wide brimmed hats whenever the kids go out in the sun in summer. We all know it is necessary but it has become such a palaver to get a bunch of (often reluctant) kids all wearing their rashies (UV protective swimming gear), all creamed up and hats on just to to play in the sand and splash in the water.
Being of the generation that used to sunbake (such an accurate description!) marinating in baby oil we have certainly changed our habits. These days with changes in the ozone layer the Ozzie sun really, really burns; it is now so much fiercer than any of us oldies remember. I really notice the difference in the European sun, it just seems so gentle in comparison.
Seem to have digressed a bit from cleanliness to allergies to sun screening. ?
