Loved it, but honestly the first few chapters would have sufficed. It's nice to read about other people's experiences and how it's improved their lives, but the scientific part was better. The last chapters weren't my thing at all, about the spiritual mindset. However, I'm excited to see how the cold exposure and breathing exercises will improve my health!

Wim Hof might be oversimplifying stuff by saying that every condition can be improved by using his method but at the beginning and in the end he gives disclaimers and advises consulting your GP before starting practicing.
The three pillars of his method are very simple: breathing, cold water exposure and the power of the mind. 
Breathing is the strongest life force. It's been confirmed by multiple studies that stimulating the vagus nerve by belly breathing improves anxiety and depression symptoms overtime. 
Cold/contrast showers are stimulating the cardio-vascular system and they have been around for centuries (think Roman baths). 
But I think the main takeaway from the book for me is the power of commitment and self-discipline. This third ingredient is essential to reap full benefits of the method. My experience with the method have brought me mental clarity and razor-sharp focus, which if put into good use, can bring loads of joy and fulfilment. Everything that we need is already within us.
