Common manifestations of allergy include asthma, allergic rhinitis, atopic dermatitis, and food allergy. Subjects with allergic diseases are usually atopic,and develop sensitization to common allergens. Having said that atopy is only one part of the oh so very complex allergy spectrum.



The disease course of asthma is influenced heavily by the home environment and the exposure to multiple potentially harmful compounds may begin prenatally and continue through childhood. Observational studies have suggested that an intense exposure to a particular allergen, during pregnancy could increase the risk of offspring being sensitized to that allergen and having allergic asthma. It is now known that allergens can pass through the placenta and sensitize the foetus.

Solutions for these exposures are available and should be actively sought out by all.Knowledge gaps exist, in particular concerning the development of the complex nervous system of a child in the milieu of multiple exposures

Examples of harmful home exposures include lead, which can be a particularly harmful neurotoxin along with other neurotoxins,such as pesticides, which work by poisoning household pests and affect similar metabolic pathways in children. The quality of air and the presence of mold, ETS, and pet dander in the home contribute to or detract from the health of a child.

Homes contain a myriad of products, chemicals, and objects that offer exposure hazards to children. The 5 categories of substances most frequently involved in paediatric exposures are cosmetics and personal care products, cleaning substances, analgesics, foreign bodies, and topical agents. So as a parent you should make a conscious effort in knowing what it is exactly you are bringing in to your home and making sure your child is safe. A note should be made here about a common indoor work activity for youth across many industries which is cleaning and use of cleaning products. Acute exposures to disinfectants and sanitizers usually involve inflammation, oedema, and burns not to mention the development of respiratory problems and increasing chances of developing cancers.

Target your focus on primary prevention. So instead of filling your home with anti this and anti that medications(secondary preventions by treating the symptoms)simply avoid exposing yourself and loved ones to agents that are suspected or known to be harmful. Remember brand loyalty kills and you do not need to be rich in order to be smart and stay healthy.
