熬夜为什么会爆肝？Does staying up late injure your liver?

爆肝，是指急性肝衰竭，就是说大量肝细胞被破坏，不能正常工作，失去排毒和代谢的能力。

“熬夜爆肝”只是世俗用来形容熬夜太过的夸张说词，在西医解释上并不会影响肝功能。但如果你在熬夜的过程中吃宵夜和饮酒就容易得脂肪肝。

中医子午流注里晚上11点到凌晨3am是气血必须回流肝脏得时候。如果没能在这时段入眠，头脑还很活跃，身体会察觉到这部位需要更大供应，气血会自动留到那里去维持活动，而不会回流到肝脏。这时候肝脏没有气血的濡养，长期下来会造成肝火旺和肝血不足的情况。出现情绪暴躁，干眼症，月经延后，月经量少，脾胃问题等。
