One of the misconceptions: allergic rhinitis is just a bit painful when it strikes, afterwards it is still the same as a healthy person, it does not matter whether it is treated or not. This is undesirable and even very dangerous. Medical statistics show that a large proportion of patients without active treatment will suffer from allergic rhinitis, exudative otitis media, bronchial asthma and, in serious cases, life-threatening conditions. Therefore, active treatment is necessary, and the World Health Organization has put forward the leading idea of preventive treatment for the disease, which means that prevention is the main focus to prevent attacks. Myth No. 2: Allergy is a sign of a stronger immune system. There has never been a single academic report about allergic people having higher resistance to viruses or bacteria than normal people. What we have seen is that when the flu is prevalent, the incidence of allergic people is not at all lower than that of the normal people. Therefore, allergy is actually a pathological immune enhancement. Myth No. 3: Allergens such as pollen, willow, dust, etc. are induced by direct contact with the nasal cavity, conjunctiva, and trachea. Allergens are contacted by the body, and the body’s immune system activates mast cells, basophils and releases allergic mediators – histamine, slow-reacting substances into the blood, through the blood and conjunctiva, skin mucosa, airways combined with the outbreak of allergies. Myth No. 4: Allergy drugs have immediate effect, just use them when you are sick. Most of the anti-allergy drugs with immediate effect are antihistamines and hormones, which not only cause drowsiness and fatigue, but also damage to the liver and kidneys, while hormones may lead to obesity, infection, pigmentation and other problems. In addition, most of these anti-allergy drugs are effective when used, but once they are discontinued, they relapse and the symptoms are even worse. Myth No. 5: Allergies are not inherited. The Hopkins School of Medicine reported that when both parents have allergies, 70% of their children can acquire allergies; if the mother alone is allergic, the children have a 50% chance of inheritance; if the father alone is allergic, the children have a 30% chance of inheritance; but there are also allergies that appear within the range of brothers, sisters, grandparents, uncles, parents, and cousins. Studies have also shown that hereditary allergic reactions often occur not only in one organ, but in multiple tissues and organs at the same time or in succession. Thus, at different ages, various different allergic reactions can occur, for example, eczema, asthmatic bronchitis, or recurrent diarrhea due to milk allergy can occur in newborns and infants; then allergic cough, allergic asthma, and allergic rhinitis can occur after the age of three: and then allergic purpura can occur before and after school. However, people with allergies in the family do not necessarily develop the same symptoms or the same allergic diseases, and even people with allergies can not develop any symptoms or never develop allergic diseases in their lifetime without encountering a certain number of allergens. However, children with a family history of allergic diseases have relatively more severe symptoms and are more difficult to treat.
