Breathing. We all do it. Yet we never talk about how to breathe. Wim Hof—The Iceman—is changing that. And he’s showing people how it is possible to improve your immune system, increase your energy levels, improve your physical and mental health, and even control your body’s temperature just through your breathing. The method is based on Wim Hof’s many years of training in the natural environment. For a long time, he has tested his body's limits by exposing himself to increasingly extreme challenges. An important discovery made during this process was his ability to control his bodily functions in a way that science had not deemed possible. For example, anyone can lift their right hand and scratch their nose with their index finger, but no one can fight bacteria that have been injected into their arm. Hof can do that. He can influence and control his autonomic nervous system. The autonomic nervous system regulates human functions such as body temperature, heart rate, blood pressure and breathing, and determines whether blood vessels should dilate or contract. In other words, the biological functions that happen in your body automatically. For a better understanding of the WIM HOF method, please read the summary below
