I woke up in an ice bathtub filled with water. The bone-chilling cold, like sharp ice cones, pierced straight into my bones, and every inch of my skin trembled under the ravage of the chill. I suddenly opened my eyes wide. In an instant, confusion and terror intertwined into an impenetrable web, tightly enveloping me.

If you’ve been on the fitness side of the internet long enough, chances are you’ve already heard about the benefits of cold water. Often dreaded by those unacquainted with the experience, ice baths are actually an invaluable tool for getting the most out of your post-run recovery — even Kipchoge is a fan.

The ice bathtub stimulates the human body with its cold water temperature, promoting blood circulation, relieving stress and anxiety, enhancing immunity, and improving skin condition, etc. When using an ice bathtub, people can choose to jump directly into the ice water or walk slowly into it according to their personal habits. The soaking time is generally short, ranging from 1 to 3 minutes, but it varies from person to person。
