These are the main allergens inside the house; - dandruff (flakes) of animals and hair of cats, house mice and dogs. Mice are a significant source of allergens, especially for urban children; - mushrooms; cockroaches (they are a major source of asthma and can reduce lung function even in people without a history of asthma).
Some research suggests that early exposure to some of these allergens, including dust mites and pets, may actually prevent children from developing allergies. - Hidden protection against allergens. People who already have pets and are not allergic to them are likely to have a low risk of developing such allergies in the future.
This is why children who have contact with dogs or cats during their first year of life have a much lower risk of not only allergies, but also asthma (however, this does not protect them from other allergens - in particular, from dust mites and cockroaches) .
Bathing animals once a week can reduce allergens. Dry shampoos remove allergens from the skin and fur of cats and dogs and are easier to use than wet shampoos. - Limit exposure to cigarette and other smoke. Parents who smoke and have allergic children should stop smoking. Studies show that exposure to second-hand smoke in the home increases the risk of asthma and related attacks in children.
