With the arrival of spring, when nature comes alive, many are anticipating the appearance of Allergy or hay fever. More than 39% of the population suffer from allergies and this figure is increasing. Sick children and adults.
English physician John Bostock first described hay fever in 1819, and detailed symptoms of seasonal allergies, who watched at home. He believed that these symptoms are causing the new-mown hay, and this condition was called hay fever. But later it turned out that allergic reaction is triggered by many kinds of pollen.
Why are allergic to pollen? Tiny pollen into the nose, it settles on the sticky mucosa. From there she moved to the nasopharynx, then she or be swallowed or removed when sneezing – in the body there is no problem.
However, pollen can sometimes cause a reaction of the immune system in people with allergies. Pollen contains protein molecules, and the immune system reacts to a protein as a risk. So the body starts to happen a defensive reaction: mast cells release histamine in large quantities. Histamine dilates blood vessels, they lose density and they become a liquid rich in immune cells that the average person help the body to get rid of the infection. But in the body of a person suffering from an Allergy, pollen is called a false alarm, triggering immune cells to reject foreign substances, even if they are a danger. The result is irritation of the nasal mucosa, runny nose, swelling of tissues, watery eyes.
Why today many people suffer from hay fever? Spanish doctors put forward two versions. The first version – the diesel engines. Particles generated by the combustion of diesel fuel, stimulate an allergic reaction. Allergists say that in industrialized countries, most often in large cities, up to 20% of the population suffer from hay fever.
The second version – the excess of hygiene. Man is born in a sterile environment, sterile eating food, making vaccinations against various diseases, and it is ill – just takes antibiotics. So, for the development of Allergy our immune system becomes fertile ground.
