The Wim Hof Method comprises three components: breathing exercises, training your mindset and concentration, and gradual exposure to the cold. For my trial, I focused mainly on the breathing exercises (though did dabble with the cold exposure).
Research shows exercise can ease things like panic attacks or mood and sleep disorders, and a recent study in the journal Lancet Psychiatry found that popular team sports may have a slight edge over the other forms of physical activity.
The breath is the foundation of every mindfulness practice, and it is also the foundation of life. Establishing a relationship with your breath, especially while pregnant, will have lasting effects for you and the child you are bringing into the world.
