In this episode, we are joined by the founding members of Apex Cool Labs, Ariel Paul and Evy Lyons to discuss their new palm cooling device “The Narwhal”. Ariel and Evy share their inspiration for creating Apex Cool Labs, how they first connected over a Tweet, all the prototypes and testing they went through to get to their final product. They also discuss how your core body temperature and local muscle temperatures affect performance, why palm cooling is such an effective tool, how to use palm cooling for downregulation at the end of your workout and to reduce delayed-onset muscle soreness, and the optimal temperature for palm cooling to see results.
