I describe mechanisms by which deliberate cold exposure can enhance mental health, physical health, and performance. I detail specific protocols to safely engage in deliberate cold exposure, including minimal exposure times, time-of-day effects, determining optimal temperatures, recovery, mindset, and movement during cold exposure. I discuss how cold exposure can be used to safely stress the body to improve attention, mood, and cognitive focus and boost metabolism and reduce inflammation. Also, I explain how cold exposure on specific regions of the body (called glabrous skin surfaces) can be leveraged to enhance endurance and weight training and increase work output.
