(M26) Any advice on getting really tired after cold plunge? I’ve been plunging for a few years now. Inconsistent though, I’ll not plunge for a few months then will for months. I just upgraded to white wolf barrel (they absolutely killed it), and plan on being more consistent. I’ve experienced both extreme tiredness, like fighting the urge to take a nap, as well as a nice energized feeling after. Trying to better understand the science/biology behind the tiredness and if it fades after a week/weeks of consistent use (I want to feel energized). Any tips/tricks appreciated!
