Ice Mile Dilemmas – IX – Safety Is Everything

The Average Person? As a responsible extreme cold water swimming promoting organisation, it’s frustrating that the IISA doesn’t seem to appreciate its responsibility in promoting safety and reducing risk. The three-article critique on the IISA rules comprehensively illustrate many of the inherent problems, omissions and contradictions. The concerns of my correspondents and myself with Ice…

Cold Water Acclimatization

This post was a companion to HABITUATION, both of which I wrote in early 2010. Since I revisited and largely rewrote that as Cold Water Habituation, my plan was to do the same in this post also. Acclimatization (acclimatisation for those of us who forego the use of the z)  is a different factor to habituation. While…

Cold water immersion and cold-shock, the first three minutes

I’d hazard a reasonable guess that what puts people off real cold water swimming is not what I write so much about, that is, hypothermia and cold exposure over long periods. Instead I’d postulate that it is the thoughts and fear of the initial cold shock and of the difficulty and pain involved with immersing…

Comments on Diana Nyad’s Heat Drip device

(To be clear, other than that, I have had no contact with Diana Nyad and don’t know her).…

Introducing a precise open water swimming temperature scale

Next year’s Cork Distance Week will have a record number of attendees, many from outside Ireland. Some will be coming nervous or terrified about the potential temperatures especially if they heard any of 2011′s details. They need a scale of reference for that fear and we need a common terminology! Steve Munatones on Daily News…

Long Duration Exposure Effects of Cold Water

This is quite simple but if you really understand it, it explains a lot of other things. We’ve briefly covered the various stages of hypothermia. For regular cold water swimming, the important thing here is that as temperature decreases blood-flow changes. Blood circulation from the extremities to the core decreases, in order to protect the…

La Jolla Bay and a hypothermia tale

I’ve surfed in San Diego and swam in La Jolla Bay, in San Diego, a couple of times, last time in middle 2008. La Jolla particularly was a great swimming experience for a cold water swimmer like. On friday nights all the local triathletes, including some the of the world’s top professionals, swim from La…
