What is rehydration clause in boxing?

A rehydration clause in boxing is a stipulation included in a fighter's contract that limits the amount of weight a fighter can gain back after weighing in for the fight. This clause is typically used to prevent fighters from gaining a significant weight advantage over their opponents by dehydrating themselves to make weight and then quickly rehydrating before the fight.

Rehydration clauses are often used in championship bouts and high-profile fights to ensure a level playing field and reduce the risk of injury to fighters. The specifics of the rehydration clause, including the maximum allowable weight gain and the time frame in which the fighter must weigh in again, are typically negotiated between the fighters, their teams, and the fight promoter.

By enforcing a rehydration clause, promoters and governing bodies aim to protect the health and safety of the fighters and maintain the integrity of the sport. This practice has become more common in recent years as extreme weight cutting has come under scrutiny for its potential dangers to fighters' health and competitive fairness.
