Apparently, comfort and development have a downside. At least that’s what various investigations suggest that they attribute to the comfort and good environment for many of today’s homes in the western world an increase in allergic diseases.
Allergies are a global public health problem. In fact, allergic rhinitis, which is the most frequent haunts one in ten people and it is estimated that only in the United States, more than fifty million people with this problem.
While allergic rhinitis is not a serious health condition affects the quality of life of the sufferer, causing complications such as mouth breathing, sinusitis, asthma, ear infections with hearing loss and poor performance in school life by chronic condition status.
According to allergists, this condition has increased in recent years a serious degree. One possible explanation is the degree of comfort with the social housing of a certain segment of the Western world. It appears that environmental allergens, especially house dust mites and fungi atmospheric multiply more and better in warm, comfortable homes.
Scientific definition
An allergy is a reaction of disagreement between the agency and some substances. This varies from person to person. Substances that cause allergies for an individual may not have the same effect in another. In conclusion, it is your body’s hypersensitivity to certain substances and physical agents.
The allergy manifests itself in various ways. One is the itching and hives. They are known by doctors as contact dermatitis. It is an allergy caused by direct contact with skin. The objects most common causes are: watches with bracelets plastic, metal or leather, glasses, metal buttons and elastic panties and bras. The symptoms are accompanied by itching, inflammation, similar to insect bites.
Vomiting, cramps or diarrhea, may be reactions of the organism against a type of food eaten. Foods that commonly cause this type of reaction are shrimp or prawns, spices, seafood and chocolate.
The bloodshot eyes are symptoms of allergy to substances found in the air. Lacrimal secretion is the symptom that causes inflammation of the conjunctiva. Allergy Attacks of this type occur commonly with sudden temperature changes or high levels of pollution.
Cough and shortness of breath are symptoms of respiratory allergy. It can be caused by many substances, but the most common is the dust, where the mite. This case also triggers bronchial asthma, in addition to temperature changes.
Powder, disinfectants, insecticides, perfumes are the most common causes of allergy. The constant sneezing are the body’s primary reactions against these allergens before they reach the lungs. The mucus-producing sneezing and produce allergic rhinitis.
Pollution and Allergies
Rhinitis, asthma or another allergic condition may be aggravated due to the quality of air we breathe. Since the beginning of this century, had already perceived the relationship of allergic box, however the Effective environmental control measures gained in importance only after several years. On one hand, several doctors and patients and are a little more attentive to environmental conditions, on the other, the process of increasing urbanization and industrialization contributes to the problem.
Several epidemiological studies show that the incidence of allergic problems increased in the last two or three decades and is proven that this increase is due to the constant increase in air pollution. Increased air pollution, mainly in large urban centers and highly industrialized regions contributed to the increase of respiratory diseases.
With increased environmental degradation and exposure of people in highly industrialized areas, we can note the emergence of occupational diseases as a result of direct exposure to agents pollutants. These groups are exposed to many environmental contaminants in an acute or chronic. People breathe 10 to 15 thousand liters of air per day, each liter contains several millions of particles in suspension, as well as volatile organic compounds.
To better understand the effects of pollution on respiratory diseases is necessary to understand the function of the nose in filtering and air conditioning. The air passes through the airways to be cleansed of its contaminants and conditioning, that is moistened, warmed and filtered to reach the pulmonary alveoli of purest way favoring gas exchange. When found in the nasal cavity, air is compressed air passages narrow, 2 mm.
These narrow passages not only facilitate the exchange of heat and substances, but also provide the contact of pollutants with the mucosa and local lymph organs.
In childhood and in old age
Allergies are a serious pediatric problem which seeks an explanation is hereditary, because it is transmitted from father to son in families for generations.
But while most of allergic diseases occur in childhood, not a few elderly patients with such conditions, more so today, when the longevity increase.
One of the most common allergic disorders at this stage of life are contact dermatitis, mainly caused by prolonged skin exposure to potential allergens and the elderly because the skin alterations in the per-cutaneous absorption of various allergens, which can be in cases such as the use of hair dyes, for example.
As with any chronic disease-such as allergies-compliance with treatment is essential to achieve success. The availability of drugs that do not interfere with the quality of life of patients receiving it is a key for it to comply with prescribed therapy.
The allergy most modern, which have the advantage of being used by people suffering from allergies without them alter their daily activities are a step in that direction.
To date, the allergy is characterized by having one of its major side effect of drowsiness. This made them unsuitable for the workplace, specifically in work related to automobiles, airplanes or intellectual activity, such as schooling.
