He established the Guinness World Record by covering his body in frozen ice for one hour and nearly 14 minutes. Three years later, he broke own record by staying in an ice bath for a total of one hour and fifty-three minutes.
Hof has set the world record for longest time in direct, full-body contact with ice a total of 16 times, including 1 hour, 42 minutes and 22 seconds on 23 January 2009; 1 hour, 44 minutes in January 2010; and 1 hour 53 minutes and 2 seconds in 2013. This was surpassed in 2014 by Songhao Jin of China, with a time of 1 hour, 53 minutes and 10 seconds; and surpassed in 2019 by Josef Köberl of Austria, with a time of 2 hours, 8 minutes and 47 seconds.
When exposed to cold, the human body can increase heat production by shivering, or non-shivering process known as thermogenesis in which BAT, also known as brown fat, converts chemical energy to heat. Mild cold exposure is known to increase BAT activity. A group of scientists in the Netherlands wondered whether frequent exposure to extreme cold, as practiced in the Wim Hof Method, would have comparable effects. The Hof brothers are identical twins, but unlike Wim, Andre has a sedentary lifestyle without exposure to extreme cold. The scientists had them practice Wim’s breathing exercises and then exposed them to the lowest temperature that would not induce shivering. They concluded that, “No significant differences were found between the two subjects, indicating that a lifestyle with frequent exposures to extreme cold does not seem to affect BAT activity and CIT.” Both had rises of 40% of their metabolic rates over the resting rate, compared to a maximum of 30% observed in young adults. However, their brown fat percentage – while high for their age – was not enough to account for all of the increase. The rest was due to their vigorous breathing, which increased the metabolic activity in their respiratory muscles. The researchers cautions that the “results must be interpreted with caution given the low subject number and the fact that both participants practised the g-Tummo like breathing technique.”
