Now admittedly I’ve been winter swimming in icy waters in Scandinavia since I was 3 years old (voluntarily following my mom in the ocean, mind you). I’ve always been keen on the benefits of cold-and-heat alternating therapies and how it can tone our vagus nerve and thereby help alleviate stress and build resilience.
However, right now this cold therapy trend is getting out of control.
This trend is being pushed by influencers with no health education or people without an understanding of the nervous system - yes, even researches focusing on one aspect only i.e. how cold therapy can change our fat tissue. However, this is ONLY one aspect of how cold therapy is affecting us. We need to understand the bigger picture of how something is affecting us LONG-TERM and our body as a whole, before we dive in. Most importantly we need to understand how our own nervous system is wired and what therapies is best matched to that. Too many lack the understanding of doing things in short bursts or in moderation to stress the body short-term in order to build resilience long-term - instead they are pushing the body beyond capacity, staying in ice water for 5-20 minutes with the mantra “more is better” or just being solely focused on changing fat tissue without understanding what large doses of adrenaline release does to the nervous system.
