Welcome to my Lab. On our quest of #forgingtheshield, you will often find ideas inspired by nature. This time I want to point you towards ‘the cold’. Exposure to cold offers many possibilities to #forgetheshield and improve your immunity. But why is that so and how does it work?
Based on solid scientific research, cold exposure is an effective tool against localized inflammation such as an aching knee, and works by fighting inflammatory markers overall. It possibly ‘trains’ the vagus nerve, helps with fat conversion from (bad) white fat to (good) brown fat – the expression “freezing your a** off” is true! In addition, exposure to cold trains the body’s capabilities of maintaining homeostasis. What’s more, it also affects insulin response.
White fat is the major source of obesity/inactivity-related inflammation and permanently increased inflammatory markers are a main contributor to an ineffective shield. While improved capability of maintaining homeostasis might be a superpower during a cytokine storm, and if you are serious about #forgingtheshield, then you should probably try getting in touch with the cold.
So what are the options? In terms of getting in touch with cold, there are many variations to choose from: cold showers, cold water swimming, an icebath or a visit to a nearby Cryo chamber. During winter time, you can take a shiver walk outdoors – dressed in the bare minimum cover according to social standards, skiing in your underwear, and so on.
There are still many people saying “Thanks, but no thanks!” to this powerful force, but exposing your body to the cold is probably one of the most indisputably effective biohacks I know.
If you’re not keen to ‘dive in’ or ‘take the plunge’ right away, start small with intermittent hot/cold showers – doing 30 seconds hot, 15 cold, 20 hot, 10 cold, for 2-3 minutes does the trick to get accustomed to this ancient strategy.
