I am writing the "Liver Health" module, the topic is sauna and I wanted to share few thoughts on this. Let's go back in time :) Growing up, sauna was not a wellness tool. It was just life. Every single night without fail, we had a sauna, 100-120 C degrees! We sat, we sweated, we forgot about the day. We talked, we let the body relax and we wound down. That was how the day officially ended. And in winter, we would run from the steaming hot sauna straight to the frozen lake, jump through the hole cut in the ice, completely naked, then run back in. It was glorious and completely normal to us. That is where my relationship with sauna started. And it has never changed. I genuinely believe traditional sauna is one of the most powerful health and wellness tools available to us. The heat, the sweat, the cardiovascular response, the nervous system reset, the sleep that follows. There is nothing quite like it. And decades of serious research backs this up. Studies following thousands of people over 20 plus years show significant reductions in cardiovascular disease, dementia, respiratory conditions and overall mortality. This is not trend wellness. This is a thousands of years old practice with real evidence behind it. And then there is infrared....... I'll be honest. I can't get on board with it and here's why. Infrared feels to me like a modern, convenient, slightly sterile version of sauna that arrived with very big marketing claims and very little actual research to back them up. I am not convinced about the exposure to the frequencies either. The studies on traditional sauna have been building for decades. The infrared research is thin, recent, and in some areas raises more questions than it answers. My concerns around infrared come down to a few things. Near infrared has been linked to cataract development with repeated exposure, there are open questions around how it interacts with cells that already have some damage, and sitting centimetres away from heating panels multiple times a week for years raises EMF questions that nobody has properly answered yet. Not proven harmful, but not proven safe either and that gap is enough for me.
