Lifestyle
Where you live and in what conditions has great
influence on your chances of developing an allergy. If you live in
a warm, fairly damp house, you create an agreeable climate for
house dust mites, increasing the odds of an allergic reaction.
Of course, smoking is known to be detrimental to our health. If you are allergy-prone, you had better consider giving up smoking, as smoking is often the last straw. It accelerates the development of allergic reactions, partly because it makes the airways more sensitive to allergens. Also avoid second-hand smoke (passive smoking).
