注意小朋友健康 由鼻敏感做起 Take care of children’s health starting from keeping from Nasal Allergy.

「鼻敏感」是指呼吸道受到空氣中的過敏原入侵後，體內的免疫系統產生抗體抵抗外來物質，鼻粘膜因受過敏原的刺激而出現連鎖過敏反應，促使鼻腔產生發炎、鼻塞、流鼻水、嗅覺不良、呼吸不暢順、眼癢或流眼水等生理症狀。1

雖然對於3歲以下小朋友患有鼻敏感症狀的案例較少，但隨著小朋友年紀的增長，六至七歲的兒童最高有42%患有鼻敏感徵狀。嚴重的甚至會因鼻塞影響睡眠質素，令日間容易感到疲倦，難集中精神上課，有機會導致學業成績變差。而誘發鼻敏感的成因包括有花粉、塵埃、霉菌、毛質、動物的體毛和寄生於家居未褥及家具的蟎蟲等，雖然現實仍未有根治過敏的方法，但治療和預防鼻敏感還可以靠環境因素的控制。例如在潮濕日子或下雨天，使用抽濕機讓室內濕度保持於50%以下，減少塵蟎滋生的機會；採用空氣過濾器，保持空氣清新無菌；同時加強預防曱甴等昆蟲的出現，以免其排泌物成為致敏原等。

Nasal Allergy is a series of chain allergic reactions in nasal mucosa stimulated by allergens, and after the allergens in the air invade stimulus, immune system produces antibodies in response to foreign substances.

Even though the case of having nasal allergy with children under 3 years old is rare, with the growth of children, there are 42% at most of children aged 6-7 having the symptom of nasal allergy. The worst situation is that rhinobyon affects sleeping quality of children, which makes children easily feel tired in the daytime and be difficulty in concentrating on lessons so that children may decline in academic performance. Origins of nasal allergy include pollen, mould, fur and acarid parasitized in bedding and furniture, etc. Currently there is no radical treatment for allergy, but treating and preventing nasal allergy can be controlled by environment factors. For example, in humid or rainy days, you can use dehumidifier to keep humidity below 50% indoors so as to decline mites breeding; you can also use air filter to keep fresh air; and you should prevent cockroaches and other insects for fear of excrement as allergens.
