海豹突击队员告诉你，为何要用冷水沐浴

Cold water will wake you up, without a doubt, and it will keep you awake.

冰水可以唤醒你，毫无疑问，它会让你清醒。

But it has more health benefits than anything else. In SEAL training you spend a lot of time in cold water and there’s actually some science to the madness of putting us in cold water. One, the reason professional athletes do it all the time after a workout is it increases recovery. It vasoconstricts the entire body, squeezing out all of that lactic acid so that you can feel good to go the next day and be ready for the next day training.

但它比其他任何东西都更有益于健康。在海豹训练中，你会花很多时间在冷水中，事实上，让我们泡在冷水中，是有一些科学道理的。第一，职业运动员在锻炼后都会这样做的原因是它加快了身体的恢复。它会收缩整个身体，挤压出所有的乳酸，这样你第二天就能感觉良好，为来日的训练做好准备。

That cold water is therapy. Even though it was torture, it’s therapy so that it keeps you healthy, keeps your joints and inflammation down, vasoconstricts everything down and allows you to keep moving forward, hopefully without any more injury.

冷水就是一种治疗。尽管它有点折磨人，但这种治疗能让你保持健康，保护关节，减少炎症，血管收缩，让你继续前行，不再受更多的伤害。
