The cold exposure movement refers to the practice of deliberately exposing oneself to cold temperatures as a form of physical and mental challenge. This can be done through methods like cold showers, ice baths, or spending time in cold environments. The idea is that this intermittent challenge can have various health benefits. For instance, even 20 seconds of immersion in 49-degree Fahrenheit water can lead to long-lasting increases in epinephrine, also known as adrenaline, and potentially other neuromodulators and neurochemicals.
However, it's important to approach cold exposure responsibly. If you're feeling good, you can do your deliberate cold exposure and not worry too much about warming up immediately afterwards. But if you're not feeling well, it's best to avoid stressful challenges like cold exposure.
In terms of building resilience, it's beneficial to vary your cold exposure practices. You can adjust the duration and temperature, and even set mental "walls" to overcome during each session. This can help you build mental toughness and resilience over time.
