Sanjay Gupta: 我个人减少了淋浴的频率,几乎不使用洗发水,只用清水洗脸。我认为这有助于我开始新的一天,这是一种日常的仪式感。 James Hamblin: 通过研究,我发现我们日常的个人卫生习惯中,大部分是文化和个人偏好,而非实际的健康益处。市面上很多清洁产品夸大其健康益处,我们对不使用这些产品的人存在偏见。其实,除了洗手和清理体液外,大多数清洁产品只是为了让人看起来、感觉和闻起来更好,这是一种社会规范。过度清洁会破坏皮肤微生物群,然后我们又试图通过益生菌等产品来补充它,这是一种不必要的循环。热水澡和清洁剂会暂时破坏皮肤微生物群,这可能会加剧炎症性疾病。除非是手术等特殊情况,否则抗菌肥皂的效用不大。无菌和卫生经常被混用,但它们并非一回事。卫生有助于去除可见的污垢,例如通过洗手去除喷嚏或咳嗽后残留在手上的粘液。人们对清洁的观念存在很多误区,因为这方面仍然比较私密,存在很多污名化。如果感觉良好且不冒犯他人,那么可以减少清洁的频率和程度。改变卫生习惯应该循序渐进,而不是突然改变。剧烈运动后需要清洗掉汗水和污垢,但通常清水就足够了。肥皂的主要作用是去除难以用水冲洗掉的污垢。总的来说,我不建议大家减少淋浴次数,而是希望大家能够更理性地看待清洁行为,根据自身情况选择合适的清洁方式。市面上很多清洁产品夸大其健康益处,人们应该根据自身情况选择清洁方式。如果某种清洁方式让你感觉良好,那么就坚持下去;如果觉得繁琐或无效,可以尝试减少清洁频率和程度。新年计划不应总是增加更多的事情,有时减少一些事情反而更好。

Chapters
Dr. Sanjay Gupta and Dr. James Hamblin discuss the cultural aspects of showering habits and the science behind the skin microbiome. They question the necessity of daily showering with soap and shampoo, considering whether it is mostly cultural preference or actual health benefit.
  • Daily showering is largely a cultural and personal preference, not necessarily a health requirement.
  • The skin microbiome is affected by frequent showering, potentially disrupting its balance and leading to skin issues.
  • Excessive showering might remove essential oils from the skin, which is detrimental to its health.
