Wim Hof breathing and cold-exposure method may have benefits, study finds

Adrenaline release thought to dampen inflammation, but experts say method ‘not without risks’

Whether plunging themselves into ice baths or deliberately hyperventilating and then holding their breath, devotees of “The Iceman” Wim Hof are evangelical about the physical and mental benefits these practices bring. A new study suggests they may indeed reduce levels of inflammation in the body. However, experts stress that practising the Wim Hof method is not without risk.

Hof is a Dutch athlete, best known for record-breaking feats such as swimming under ice and running barefoot on ice and snow. More recently, he has built a business empire on the techniques he uses – which focus on a commitment mastering conscious breathing and cold exposure – with courses available around the world.
