I am creating a YouTube video on amazing human feats that have been performed. What is the coldest temperature that a person has survived naked for an extended period of time?
user
I believe the coldest temperature a human has survived naked for an extended period of time was -88°F, in 1969 by an Australian man.  The record is currently held by the late, great Fyodor Yemelyanenko, who survived at a temperature of -122.2°F, in 2008.

Can you give me some background information for the situation that Fyodor Yemelyanenko was in during the feat?
user
Fyodor’s feat was intended to demonstrate that the human body can survive extremely low temperatures for an extended period of time.  The temperature was recorded by Fyodor’s arm, which was resting against a bench, and had an air temperature of -122°F.  Fyodor stayed in the situation for three hours and 50 minutes, his heart rate dropped to 36 beats per minute.  He was supported by a team of four men, two on each arm and two on each leg.  To the extent that I can extrapolate from the above information, it seems like Fyodor was immobile in this situation for much of the time, and was supported by a team, so I’m not sure how relevant this is to the situation that you’re describing.

According to Yemelyanenko’s web site, he experienced approximately a six hour long exposure to -122.2°F.  As a result of this exposure, he sustained over 70 broken bones.  There are plenty of accounts of his exploit in the media, including this article from The Telegraph.  One piece of footage from his exploit is available here, and several other sources can be found on this page.  There is a lot of information available on Yemelyanenko’s own site, including a video of his survival, and other interviews and articles.
