Specifics of combining freediving with ice cold water swimming

Hi everyone. I am curious about one topic and I could not find much about it online. I am interested in freediving in very cold water and I want to learn more about the specifics of dynamic apnea under ice. There is a ton of info on dynamic apnea and on cold water swimming separately. But not much info on what exactly happens if you combine the two. Stig Severinsen is currently a world record holder for DNF in just speedos underneath ice with almost 80 m on a single breath. He is a freediver who achieved 180m DNF in regular swimming pool... So my question is... How exactly does translate regular freediving into ice cold water one? What happens to the body during breath hold in ice cold water and how does cold water affect your dynamic apnea skills? (Because this is just not a question of how long you can stay in cold water - trained cold water swimmers are able to stay in 3°C water for dozens of minutes. Does it mean if they could swim the same distance there like in a regular pool if they were also trained freedivers?) Or does the urge to breathe simply come earlier in cold water due to stress levels, some physiological phenomena or the need to supply muscles with more oxygen so that they can work in cold environment? Thanks for your insights, M.

Do you mean with or without a wet suit? I don't know about swimming in ice water bare skinned. But if you are wearing a thick enough wet suit you can freedive OK even in ice cold water. However, a thick wet suit will make buoyancy/weighting a bigger problem.
