During the reversal of seasons, will you experience the itchy eyes, stuffy and runny noses, scratchy throats, and sneezing? If so, you may suffer a seasonal allergy.
Seasonal Allergy is skin sensitivity. Anyone, no matter the gender, race, age or where you live can have seasonal allergies. Symptom may be temporary for someone, but often starts when a person is a child to last a life time. Seasonal Allergies happen in all months; spring and autumn have the most complain.The reason why is that both the two seasons are the best time for flowers, trees, grass, and weeds to pollinate in advantage of wind. The light, small pollen spread in the air triggering your immune system at any time.
Those substances trigger your body’s reaction are called allergens. Except for the pollen, there are other factors shall be blamed.
Dust is a mixture of many substances, like cotton fiber, fur, various fibers and dust mites. Among these components, dust miles has been proved that they are the most important allergens that cause allergic asthma in humans. Dust mile is a kind of microscopic animal with 8 feet. The main realms for them to live in a house are the bed membrane and inconspicuous corners; no matter where it is, dust mites can always get mixed into the dust.
2) Mold and germ
Mold is a fungus like mushrooms; and it’s made up of thread like filaments called hypha. It uses those filaments like roots to feed, extend into the our food, wall, ceiling, etc and start releasing digestive enzymes. The reason for a mold allergy is similar to germ allergy. The reason why allergic bacteria cause human allergies is that the bacteria can cause the production of histamine in the particles of mast cells and basophils in the human body. Histamine is one of the self-active substances and formed by the decarboxylation of histidine, which has a large amount in the skin, bronchial mucosa, intestinal mucosa, and nervous system. When the body is subject to physical and chemical stimulation or allergic reactions, these cells can cause degranulation, leading to the release of histamine and binding to histamine receptors to produce biological effects.
3) The change of temperature
During the reversal of seasons, temperature changes violently. In such an environment with the high temperature and humidity, the mold and germs have enough nutriment to breed rapidly. Even if the immune system is in a good state, it is impervious to the constant onslaught of mold and germs. When moisture contained in the skin will be decreased greatly.
4) Functional degeneration of skin
Along with the age, the cuticle of our skin become thinner over the years so that the skin will be sensitive to substances. Meanwhile, the degraded secretion system of skin has a lower efficiency to repair those defected cells and it takes longer time to recover itself.
