50%1 of children in the UK now have some form of allergic condition. Why is this figure so high? It would seem that the rise in allergic sufferers could stem from a number of contributing factors.
With European children spending at least 90% of their lives indoors, the indoor environment is probably more important than other geographic and outdoor environmental factors. Many modern homes are built with economy in mind and are therefore effectively sealed off with little or no ventilation. This can lead to high levels of humidity and consequently an increased growth of allergens such as mould and dust mites both of which are associated with having a powerful effect on atopic children, along with exposure to tobacco smoke during pregnancy and early childhood.2
