Cold exposure refers to the practice of exposing the body to cold temperatures, which can occur through activities like cold showers, ice baths, or spending time in cold environments. This exposure can stimulate various physiological responses, including increased circulation and enhanced metabolism. Many people engage in cold exposure for potential health benefits, such as improved immune function and reduced inflammation. Some proponents, like Wim Hof, advocate for its use in combination with breathing techniques to promote mental clarity and resilience. However, it's essential to approach cold exposure safely to avoid risks like hypothermia.
