2026年9月，科学领域流言榜针对八大常见健康与生活谣言进行了集中辟谣1。
关于病毒防护和疾病预防的谣言首当其冲。诺如病毒作为无包膜病毒，对酒精具有较强耐受性，酒精免洗洗手液无法有效杀灭它，饭前便后应当用肥皂配合流动水洗手才是正确做法1。感染诺如病毒后，症状消失需要等待72小时后方可返校上岗1。此外，换季输液并不能预防脑梗，因为输液无法将已形成的动脉粥样硬化斑块"冲走"，盲目输液反而会增加药物过敏、静脉炎、感染等风险1。
在食品安全方面，螃蟹激素催肥的说法站不住脚——螃蟹内分泌系统与人类差异极大，人用激素既不能被其识别利用，反而可能干扰其生理节律1。景区湖盐块更不能直接食用，这类盐块未经加工检测，除了氯化钠外通常含有氯化镁、硫酸镁、泥沙等杂质1。
在急救和用药方面，海姆立克法并非万能首选，它仅适用于清醒的重度气道异物梗阻患者。清醒成人和1岁以上儿童应先进行5次背部拍击，再进行5次腹部冲击，两者交替进行；1岁以下婴儿则采用5次背部拍击加5次胸部冲击，不能进行腹部冲击1。漏服药物后是否能补服取决于距下次服药的时间，临近下次服药时应跳过漏服，绝不能自行加倍，否则易导致血药浓度骤升和中毒1。
此外，正常衰老导致的偶尔忘记细节与阿尔茨海默病存在明显区别，后者表现为近期记忆明显受损、刚说过的事转眼就忘1。
A September 2026 science myth-busting report has debunked eight prevalent health and lifestyle misconceptions through scientific evidence 1.
The report clarifies that norovirus is a non-enveloped virus exhibiting strong resistance to alcohol, making alcohol-based hand sanitizers ineffective at eliminating it 1. Proper hand hygiene requires washing with soap and running water before meals and after using the restroom 1. Additionally, individuals infected with norovirus should not return to school or work until 72 hours after symptoms resolve 1.
The report addresses several other widespread myths. Regarding crabs and growth-promoting hormones, the report notes that crabs' endocrine systems differ drastically from humans, meaning hormones used on humans cannot be recognized or utilized by crabs and may instead disrupt their physiological rhythms 1. Lake salt blocks found in scenic areas contain untreated minerals including magnesium chloride, magnesium sulfate, and sediment alongside sodium chloride, making them unsuitable for direct consumption as table salt 1.
On emergency response techniques, the Heimlich maneuver applies only to conscious patients experiencing severe airway obstruction 1. The proper protocol for conscious adults and children over one year old involves performing five back blows followed by five abdominal thrusts, alternating between the two 1. For infants under one year, the recommended approach consists of five back blows combined with five chest thrusts, as abdominal thrusts are contraindicated 1.
The report further clarifies that seasonal intravenous infusions cannot flush away already-formed arterial plaque, and unnecessary infusions increase risks of allergic reactions, phlebitis, and infection 1. When medication doses are missed, whether to supplement depends on the time until the next scheduled dose—if the next dose is imminent, the missed dose should be skipped rather than doubled, as doubling can cause blood drug concentrations to spike and potentially lead to toxicity 1. Finally, the report distinguishes Alzheimer's disease-related memory loss, characterized by significant impairment of recent memory where recently discussed information is immediately forgotten, from normal age-related memory decline, which typically involves occasional lapses in minor details 1.
