The Science
The Start of Scientific Research
What "The Iceman" Wim Hof is capable of was long viewed as scientifically impossible. That changed with the 2011 Radboud University study showing Wim could voluntarily influence his autonomic nervous system a groundbreaking result that reshaped biology textbooks and inspired countless new studies.
Key Scientific Studies
Radboud University, The Netherlands (2014)
Injected 12 Wim Hof Method practitioners with an endotoxin. Results: They could voluntarily influence their sympathetic nervous system and immune response. Anti-inflammatory mediators were 200% higher, and pro-inflammatory mediators were 50% lower.
Wayne State University, The Netherlands (2018)
Known as the "Brain Over Body" study, Wim underwent cold exposure in an fMRI & PET scanner. Result: Activation of pain suppression & well-being regions in the brain. Implications for using the method to help with multiple clinical syndromes.
