What Happened to Yang Jian Bing
Yang's death followed a pattern familiar to anyone who has covered weight cutting in combat sports: a fighter using dehydration, not fat loss, to make a contracted weight limit, then attempting to rehydrate in the roughly 24 to 36 hours before competing. Severe dehydration can strain the cardiovascular and renal systems enough to become life-threatening, and in Yang's case it did. ONE Championship's response was not cosmetic. Within a short period, the promotion built a mandatory hydration check directly into its weigh-in process.
