为什么不能用手摸脸

手是我们日常生活中最常用的工具之一，我们几乎无时无刻不在使用手来完成各种任务。然而，有一项习惯可能会对我们的健康造成潜在的威胁：用手触摸脸部。尽管这看起来是一个无害的动作，但事实上，手接触到的表面可能携带病菌和细菌，这可能导致感染和疾病的传播。

Firstly, our hands come into contact with numerous surfaces throughout the day, including doorknobs, handrails, and electronic devices. These surfaces can harbor germs and bacteria, some of which can cause illnesses such as the common cold, flu, or even more severe diseases like COVID-19. When we touch our face with contaminated hands, these pathogens can easily enter our body through the eyes, nose, or mouth, increasing the risk of infection.

其次，手可能沾染许多来源于外界的污垢和化学物质。在我们的生活中，我们接触到的物品往往充满了细菌、灰尘、污垢以及其他有害物质。将这些物质带到脸上可能引发过敏反应、皮肤炎症甚至严重的皮肤感染。此外，手上的化学物质，如清洁剂和洗涤剂，可能对皮肤造成刺激和伤害。

Secondly, our hands can become contaminated with dirt and chemicals from various external sources. The objects we come into contact with in our daily lives are often filled with bacteria, dust, grime, and other harmful substances. Bringing these substances to our face can trigger allergic reactions, skin inflammation, or even severe infections. Moreover, chemicals present on our hands, such as cleaning agents and detergents, can cause irritation and damage to the skin.

此外，手还可以通过摩擦引起肌肤的刺激和压力。频繁触碰脸部会对皮肤造成摩擦，而这种摩擦可能导致不同程度的不适感、疼痛以及皮肤损伤。对于那些已经有皮肤问题的人来说，比如青春痘或皮肤敏感者，用手触摸脸部会加重这些问题并延长愈合时间。

Furthermore, the act of touching our face with our hands can cause irritation and pressure on the skin through friction. Frequent contact with the face can lead to varying degrees of discomfort, pain, and skin damage due to this friction. For individuals who already have existing skin issues, such as acne or sensitive skin, touching the face with hands can exacerbate these problems and prolong the healing process.

因此，我们应该养成避免用手触摸脸部的良好习惯。要保持手部清洁，经常洗手或使用免洗洗手液可以有效地去除病菌和细菌。同时，我们可以尝试其他方法来解决脸部的不适感，如使用纸巾或柔软的面纱轻轻擦拭脸部，或使用工具来完成脸部护理程序。

Therefore, it is essential for us to develop the habit of avoiding touching our faces with our hands. Keeping our hands clean by washing them frequently or using hand sanitizers can effectively remove germs and bacteria. Additionally, we can explore alternative methods to address any discomfort on our face, such as gently wiping the face with tissues or soft veils, or using tools to conduct facial care routines.

在日常生活中，避免用手触摸脸部可能需要一些时间和努力，但这是值得的，因为这能够降低感染疾病和皮肤问题的风险。通过养成良好的卫生习惯，我们可以保护自己的健康，同时也为身边的人提供更安全的环境。

In our daily lives, avoiding touching our faces with our hands may require some time and effort, but it is worthwhile as it reduces the risk of contracting illnesses and skin issues. By cultivating good hygiene habits, we can protect our health and contribute to creating a safer environment for those around us.
