Core Body Temperature Wim during World Record

Updated: Mar 23


In 2009 Wim conducted a World Record attempt on Regis and Kelly ABC TV Show, sitting in a bucket of ice. During this attempt, the core temperature was recorded by Granis Stewart, RN, using Vital Sense monitor capsule swallowed by Wim Hof prior to ice immersion, of the Feinstein Institute of Medical Research. The result was remarkable and apparently contradicted the medical assumptions about possible control of core temperature.


As dr. Kevin Kamler of the Feinstein Institute of Medical Research stated:

Standard medical dogma states that once your core temperature falls below 90 degrees, you stop shivering — a process that generates heat...[and] if a source of external heat is not provided, your body temperature will continue to spiral downward and you will eventually die of hypothermia."


Wim, however, proved modern science wrong, as his temperature lowered to 88 degrees, coming back got 94 degrees, without any external heat source!


This was truly remarkable and showed, according to Dr. Kamler, that modern research does not properly understands this.


Wim's temperature during the attempt:

98.6 - with clothes on

Just before they began pouring the ice in the chamber: 98.16

15 minutes after ice immersion began: 96.36

30 mins after ice immersion began: 97.44

45 mins after............................... 95.07

52 mins after............................... 93.74

56 mins after............................... 88.79

65 mins after............................... 89.94

75 mins after............................... 88.08

(oral temp at same time was 92.7) 90 mins after............................... 93.38 95 mins after............................... 94.10 100 mins after............................. 94.10 One minute before breaking his world record of 1 hour 43 minutes: 92.71


This shows us that Science is a great indicator of what is possible, but not a determinator of what is possible.
