Read: In the summer, many people will start to catch a cold, if they are not careful. This time don't think it's a simple cold, maybe it's not a cold, maybe it's a pollen allergy, for some people, pollen allergy is still very common.

Mainly uncomfortable nose, but there is still a difference with a cold.

1, pollen allergy in children have three main manifestations: one is "pollen allergic rhinitis", itchy nose, sneezing, sneezing, nose clogging, breathlessness and so on.

2, "pollen allergic asthma", manifested as paroxysmal cough, dyspnea, white foamy mucus, sudden asthma attacks and gradual weight, and after the good and normal people.

3, "pollen allergic conjunctivitis", manifested as itchy eyes, eyelid swelling, and often accompanied by watery or purulent mucus discharge.

4, hay fever, also known as chilblain fever, manifested as a runny nose, sneezing, itchy nose and eyes, as well as coughing and other symptoms. There are three main manifestations of pollen allergy in children: first, "pollen allergic", itchy nose, sneezing, runny nose, blocked nose, breathlessness, etc.; second, "pollen allergic", manifested by paroxysmal cough, dyspnea, white foamy mucus.

5, sudden asthma attacks and gradual weight, after the good and normal people; third, "pollen allergic", manifested in children's eyes itchy, eyelid swelling, and often accompanied by watery or purulent mucus secretion. Children's "pollen allergy" often occurs after 2 to 3 years old.

6, pollen allergic conjunctivitis. This is characterized by itchy eyes, swollen eyelids, and watery or purulent mucus discharge.

Difference between pollen allergy and cold

The same is uncomfortable nose, but will not be accompanied by headache and fever.

1. Consider the timing. Colds usually occur in winter and show symptoms a few days after exposure to the virus. Seasonal allergies such as sneezing, nasal congestion, and itchy eyes, on the other hand, show up immediately after exposure to pollen and usually occur in the spring, summer, or fall. If symptoms tend to appear at the same time of year, it's likely to be seasonal allergies, not a cold.

2. The color of the nasal discharge also provides a clue. When a patient's nasal discharge is green or yellow in color, it is considered a cold. Seasonal allergies usually produce clear-colored nasal discharge, even though a sinus infection may confuse the difference between the two. Sometimes allergy sufferers with sinus infections also have yellow nasal discharge.

3, hay fever performance looks like a cold, a cold in addition to runny nose, sneezing, nasal congestion, there may be a little headache, sore throat or fever, but generally do not appear itchy nose, itchy eyes, red eyes, itchy ears, etc., so "itchy" is one of the best ways to distinguish between colds and hay fever. Suggestion: We suggest you to eat less food that is easy to catch fire and drink more water to enhance your ability to resist diseases. Try to avoid contact with allergens.

4, pollen allergy on the one hand, because of the improvement of people's standard of living, in the diet intake of a large number of eggs, meat products and other high-protein, high-calorie diet, the result is that the body's ability to produce antibodies hyperactivity, and therefore meet the pollen and other antigens, it will be more prone to metamorphic reactions. On the other hand, because of atmospheric pollution, water pollution and the massive application of food additives, resulting in human exposure to more antigenic substances, prompting the occurrence of allergic diseases in humans.

5, cold is a variety of factors that lead to a reduction in the whole body or respiratory tract local defense function, such as cold, rain, sudden changes in climate, excessive fatigue, etc. can be made to have existed in the upper respiratory tract or from the outside invasion of the rapid reproduction of viruses or bacteria, thus inducing the disease.

1, avoid pollen is difficult to avoid allergens, it is best to live indoors during the onset of the season, close the doors and windows in order to reduce the entry of outdoor allergenic pollen. If you have air conditioning, you can also achieve this purpose. As far as possible, do not go to the field. If you are allergic to vegetables and fruits, you should avoid eating those allergic plant foods.

2, the application of anti-inflammatory agents If the diagnosis has been confirmed, anti-inflammatory agents should be applied before the arrival of the pollen season, such as local topical corticosteroid Eloxanol ointment, etc., manifested as nasal allergy symptoms of nasal hormones or sodium cromoglycate, accompanied by asthma, can be inhaled through the mouth of the hormone or sodium cromoglycate in order to prevent.

3, change and wash clothes: every time you come home to change the clothes, because the clothes are always inevitably stained with some pollen. If you walk around in them, it's easy to get pollen in the air, which can trigger pollen allergies.

4, not in the outdoor drying clothes: because the air contains pollen, if we dry clothes in the outdoor, it is easy to pollen. Especially those who have planted flowers inside the compound, drying clothes should be far away.
