Howdy All! Mark has been writing a lot lately about using cold water for numerous primal benefits such as fat loss, exercise recovery, and increasing metabolism through brown adipose tissue (BAT).

Here are some links to Mark's previous blogs on the topics:

Cold Water Therapy | Mark's Daily Apple

How to Conduct a Personal Experiment: Cold Water Plunges | Mark's Daily Apple

Dear Mark: Leptin Resets, Cold Thermogenesis, and Safe Starches? | Mark's Daily Apple

Is Brown Fat Good For You? | Mark's Daily Apple

There are other 'guru's' touting the benefits of cold water, let's leave them out of this and focus on tearing into what Mark Sisson is finding. His latest challenge on self-experimentation is a great place to start this thread, maybe his next book will use our data!
