痘痘
熬夜自然会导致睡眠质量变差，多数会出现肾阴亏损的问题，导致阴虚（中医指精血或津液亏损的病症）火气旺盛。火热淤积在脸部，影响了皮肤腺的排泄，容易导致皮肤分泌油脂过多，吸着一些肮脏物质，没有即时清理而造成细菌滋生，加上熬夜很容易使身体体内有很大的火气，所以容易导致痘痘滋长。
熬夜不长痘痘的方法
1.建立健康良好的生活习惯。
尽量避免熬夜，早睡早起。睡觉前，用温水洗脸以及用热水泡脚。这有助于睡眠。
2.补充身体的水分
由于熬夜会使身体体内火气很大，喝水是最经济又有效的方法，也可补充体内所流失的水分。另外，也要保持室内空气通畅，并保持空气的湿度（可准备一台加湿器或一盆水），这样就不会长痘痘啦。
3. 补充维生素C
熬夜会导致皮肤的胶原蛋白流失，尽量在吃每一餐时多吃一些含有维生素C或是含有胶原蛋白的食物（如猪蹄、猪皮），以及含有维生素C的水果。这些食物都有利于皮肤恢复弹性和光泽。
Pimples
Staying up late will worsen our sleep quality. Chinese medicine believes that lack of sleep will cause problems to the kidneys, resulting in diseases related to our blood and bodily fluid. The internal heat will become more intense. This will cause excessive secretion of oil which, if not removed quickly, will cause bacteria to breed and turn into pimples.
Ways to avoid pimples when staying up late
1. Cultivate a healthy lifestyle
Go to bed early and rise early. Before going to bed, wash your face with warm water and your feet with hot water. This helps you to sleep better.
2. Supplement the body with water
Staying up late will increase the body temperature. The best way to solve this problem is to drink more water. In addition, keep the air indoors ventilated and at a suitable humidity (e.g. install a humidifier or place a basin of water). This will prevent you from getting acne!
3. Take Vitamin C
Staying up late can cause loss of collagen in your skin. Try to eat foods and fruits which contain Vitamin C or collagen. These foods can help to restore the elasticity and luster of your skin.
