Take the Plunge

Cold exposure can significantly increase the production of norepinephrine in the body, with a consistent increase of 200-300% that does not diminish over time. The colder the temperature, the more pronounced the body’s response to the increase in norepinephrine production. In fact, a 20-30 second immersion in near freezing water can elicit the same level of increase as a 6 hour walk in 60°F weather.
