cold plunges — 60 days in, here is what actually changed

3 min at 50f, 4x per week. what changed: morning energy noticeably higher, less afternoon crash, mood more stable. what didn't change: weight, sleep onset, resting HR in any meaningful way. the hype is real but narrower than influencers claim. it's a mood + energy tool. the fat loss stuff is overstated imo.
