“Pressing the philtrum” (the groove between the nose and upper lip) is a traditional first-aid method commonly used in China to treat fainting or unconsciousness. However, modern medical research shows this practice is not scientifically supported and may even pose risks.Traditionally, it’s believed that stimulating the philtrum can “revive consciousness.” In reality, fainting is usually caused by a temporary reduction in blood flow to the brain—such as vasovagal syncope or cardiac-related syncope. The most effective response is to lay the person flat on their back, elevate their legs to promote blood return to the brain, and ensure an open airway. Pressing the philtrum does nothing to improve cerebral blood flow; instead, excessive force can cause tissue injury, skin damage, or even trigger pain-induced convulsions, potentially worsening the condition.Moreover, if fainting stems from serious conditions like arrhythmia or stroke, delaying proper medical care could be life-threatening. Therefore, in cases of fainting, one should immediately call emergency services and apply evidence-based first aid—not rely on unverified folk remedies.In summary, “pressing the philtrum” lacks scientific basis and should not be promoted as a legitimate first-aid technique. Spreading accurate emergency response knowledge is essential to truly safeguard lives.
“掐人中”是中国民间常用的一种急救方法，常被用于应对晕厥、昏迷等情况。然而，现代医学研究表明，这种做法并不科学，甚至可能带来风险。人中位于鼻唇沟的上三分之一处，传统观念认为刺激此处可以“醒神开窍”。但实际上，晕厥多由脑部暂时性供血不足引起，如血管迷走性晕厥、心源性晕厥等。此时最有效的处理方式是让患者平躺、抬高下肢，以促进血液回流至大脑，并确保呼吸道通畅。掐人中不仅无法改善脑部供血，还可能因用力过猛造成局部组织损伤、皮肤破损，甚至诱发患者因疼痛而抽搐，加重病情。此外，若晕厥由严重疾病（如心律失常、脑卒中）引起，延误正规救治可能危及生命。因此，面对晕厥，应优先拨打急救电话，采取科学的急救措施，而非依赖未经验证的传统手法。总之，“掐人中”缺乏医学依据，不应作为急救手段推广。普及正确的急救知识，才能真正保障生命安全。
