It is almost unthinkable for Americans not to shower daily. They would be as baffled by the idea of topping and tailing at the sink as they are by the thought of drying your laundry on a clothesline.
Eczema is on the rise everywhere: the NHS in 2009 said 40% over the previous five years. Some studies have blamed it on central heating, carpeting and especially bath gels and lotions.
'whereas we used to bathe only once or twice a week, we are now showering or bathing at least once a day. That in itself is not a problem. However, the nation's increased desire for cleanliness has been mirrored by an equal rise in the use of bubble baths and shower gels. Over the past 20 years, spending on such products has almost doubled in high street stores.
Crucially, both gels and bubble baths often contain chemicals that are now known to trigger eczema. 'Skin cells have various fats on their surface that help them retain water,' said Cork. 'Surfactants in gels and bubble baths can break these fats down and disrupt the cells' water content. They shrivel up - producing eczema's symptoms.'
Similarly, baby wipes have largely replaced the use of cotton wool and water. These too can 'contain crude surfactants and perfumes' which can 'decrease the integrity' of the skin, state the researchers. Again, the end result is eczema.
In addition, the increase in central heating, double glazing and carpeting has produced warmer, more comfortable homes - both for humans and for dust mites. 'Dust mites thrive in carpets in warm houses,' said Cork.
'That can cause problems for asthma sufferers, of course but it also poses problems for those prone to eczema. Dust mites secrete toxins that have much the same effect that surfactants in bubble baths can have. They disrupt skin cells' water content.'
Even cats - whose ownership has doubled in Britain over the past three decades - are involved, say the group. Their fur provides homes for mites, while they also produce chemicals that can trigger eczema.'

Hurrah for good old soap!!
I doubt people are coming after me with pitchforks for allegedly insulting them for their washing habits.
