Absolutely. While it's easy for many, it can also overstimulate the nervous sustem for others. That's why good educated guidance is so necessary and why I studied to be a Wim Hof method instructor. It's necessary to know the biological background and have the experience to evaluate where your participants stand in terms of stress level and overall health.
With the Wim Hof method you consciously play with raising the stress level through breathing and cold ... and then go into the opposite with full relaxation. That interplay is called hormesis and is what makes youbso resilient and healthy. If you overstimulate your nervous system without the proper rest and calm down, you add to your stress level and can make conditions worse over time.
