长期穿羽绒服盖羽绒被会诱发“羽绒肺”？专家提醒

Core Viewpoint - The rising concern over "down lung," a form of allergic pneumonia caused by inhaling down feathers and their associated proteins, has gained attention following a recent case of a man diagnosed after wearing a damaged down jacket for over 12 hours daily [2][3]. Group 1: Definition and Symptoms - "Down lung" is essentially allergic pneumonia, resulting from the inhalation of feather fibers or proteins, leading to an immune response that damages lung tissue [2][3]. - Symptoms can manifest within hours to days after exposure, including dry cough, chest tightness, and shortness of breath, which may worsen with activity [8][9]. Group 2: Risk Factors - Wearing damaged down products, particularly those with broken linings or seams, increases the risk of exposure to feather fibers [5]. - Prolonged use of down products, especially in enclosed spaces, significantly raises the cumulative exposure to feather particles [6]. - Low-quality down products, which may contain uncleaned and untreated allergens, pose a higher health risk [7]. Group 3: Prevention Strategies - Selecting high-quality down products with good anti-leak technology and dense fabric can reduce the risk of "down lung" [10]. - Proper usage includes airing and cleaning down products before use, ensuring good ventilation in living spaces, and addressing any damage promptly [10]. - Individuals with allergies or asthma should consider non-down alternatives for warmth, such as cotton or silk [10].
