Cold Open Water Acclimation
Cold open water acclimation builds tolerance to cool race venues through gradual exposure, safe buddies, and exit plans—not one shocking plunge.
Cold open water acclimation is gradually adapting to cool lakes or oceans so race-day shock does not spike heart rate, breath hold, or panic. Short entries, exhale-focused warm-ups, and building duration over weeks beat one heroic plunge.
Neoprene caps, ear plugs, and a calm exit plan matter as much as yardage. Never practice alone in deep water; know hypothermia signs and when to abort.
Post-swim rewarming with dry layers beats hot showers immediately if afterdrop is a concern.
