專業解析

Cold allergy, medically termed ascold urticaria, refers to a hypersensitivity disorder in which the skin exhibits abnormal reactions to cold stimuli. Patients may develop localized or systemic symptoms such as redness, itching, hives, or angioedema upon exposure to cold air, water, or objects. In severe cases, systemic reactions like hypotension or anaphylaxis may occur.

This condition is classified as a physical urticaria and involves mast cell activation triggered by cold, leading to histamine release. Diagnosis typically involves a cold stimulation test (e.g., placing an ice cube on the skin for 5–15 minutes). Management strategies include antihistamines, avoidance of cold exposure, and carrying emergency epinephrine for high-risk individuals.

網絡擴展解釋

冷覺過敏（又稱冷過敏症）指個體對寒冷刺激産生異常生理反應的臨床症狀，屬于變态反應性疾病的一種。以下是詳細解釋：

一、定義與機制冷覺過敏是皮膚或黏膜接觸低溫環境（如冷空氣、冷水）後，機體免疫系統産生過度反應的現象。其核心特征為對寒冷刺激的敏感性顯著高于常人，可能伴隨多系統症狀。

二、發病原因

遺傳因素：家族病史或基因突變可能增加患病風險。
免疫異常：肥大細胞釋放組胺等炎性介質，引發過敏反應。
環境誘因：長期暴露于寒冷環境或突然接觸冷刺激。

三、典型症狀

皮膚症狀：瘙癢、紅腫、風團（荨麻疹樣皮疹），嚴重時出現水疱或脫屑。
呼吸道症狀：打噴嚏、鼻塞、流涕，甚至呼吸困難或哮喘發作。
全身症狀：頭痛、關節疼痛，極少數可能引發過敏性休克。

四、應對與預防

防護措施：寒冷天氣穿戴保暖衣物，避免直接接觸冷空氣或冷水。
醫療幹預：抗組胺藥物緩解症狀，嚴重者需進行脫敏治療。
增強體質：適度鍛煉可提高對寒冷刺激的耐受性。

注：冷覺過敏需與普通冷敏感區分，後者僅表現為正常溫度感知，而前者伴隨病理性免疫反應。若症狀反複出現，建議及時就醫進行過敏原檢測。
