Core Viewpoint - The article discusses the increasing prevalence and severity of pollen allergies in northern China during the autumn season, highlighting the differences between autumn and spring allergies, and providing recommendations for prevention and management.

Group 1 - The term "biodegradable plastics" can mislead consumers into thinking they can be discarded without consequences, while their degradation requires specific conditions that are often not met in natural environments [1][2] - Many biodegradable plastics decompose slowly in natural settings, potentially leading to microplastic pollution, thus emphasizing the need for proper recycling and waste management [2] - A circular economy approach, focusing on reducing plastic use and enhancing recycling, is suggested as a more effective solution to plastic pollution [2] Group 2 - Osteoporosis patients are often advised to limit physical activity to prevent fractures, but appropriate exercise is essential for maintaining bone and muscle health [3] - Regular movement can help prevent the loss of bone density and muscle mass, which are critical for reducing the risk of falls in the elderly [3] - Adequate sunlight exposure is necessary for vitamin D synthesis, which is vital for bone health, highlighting the importance of balanced activity levels [3] Group 3 - The claim that covering oneself with blankets during a fever helps reduce temperature is incorrect; it can actually hinder the body's natural cooling process [4] - Maintaining a comfortable room temperature and staying hydrated are recommended practices during a fever [4] - If fever persists or is accompanied by severe symptoms, seeking medical attention is advised [4] Group 4 - The asteroid "2024 YR4" has a calculated collision probability with Earth of approximately 2%, with its size estimated between 40 to 90 meters [5][6] - The probability of collision has increased from 1% to 2.3% based on ongoing observations, indicating that such probabilities can change rapidly as more data is collected [5][6] - International cooperation has established protocols for monitoring and responding to near-Earth objects, ensuring preparedness for potential threats [6] Group 5 - The belief that wearing glasses worsens nearsightedness is unfounded; nearsightedness progression is linked to eye development and usage habits [7] - Timely use of corrective lenses is crucial for children diagnosed with myopia to prevent further deterioration of vision [7] - Encouraging outdoor activities and proper eye care can help mitigate the progression of nearsightedness [7] Group 6 - The assertion that fish oil can lower blood lipids is oversimplified; while Omega-3 fatty acids in fish oil can help reduce triglycerides, they do not significantly affect cholesterol levels [8][9] - High-purity fish oil is recommended for individuals with elevated triglycerides, but it should not replace statin medications for cholesterol management [10] - The effectiveness of fish oil supplements varies based on their purity and the specific fatty acid content, necessitating careful selection [9][10] Group 7 - The notion that allergy medications should only be taken after symptoms appear is misleading; proactive treatment can be more effective in managing seasonal allergies [11] - Preventive measures, such as using nasal sprays or eye drops before allergy season, can significantly reduce the severity of symptoms [11] - Early intervention is emphasized to improve outcomes for individuals with known allergies [11] Group 8 - The claim that NFC technology in smartphones is insecure and can lead to unauthorized transactions is incorrect; NFC requires close proximity and user authentication to function [12][13] - NFC technology operates similarly to RFID, allowing secure data exchange within a limited range, enhancing its safety for mobile payments [12][13] - Concerns about unauthorized transactions are more related to user behavior and security practices than the technology itself [14]
