Thirty Minutes in the Sauna and the Gap Before the Weigh-In: A Lesson from the 2026 Asian Games

At three in the afternoon on September 20, in the medical zone of the Aichi-Nagoya athletes' village, a Nepali athlete walked past the sauna and heard heavy breathing inside. He opened the door. On the wooden bench, a young man sat slumped, skin grey, lips cracked, both hands cramped. According to accounts recorded afterwards, he had lost consciousness for a moment and only came round when someone called his name. Games medical staff attended, took him to hospital and ran a blood test. By evening, his name had been struck from the men's under-77 kg draw of the "traditional MMA" event at the 2026 Asian Games.

The man was Sanyal, an Indian MMA fighter. That morning he had been matched against Bahrain's Mukhammad Nabiev in the quarterfinal, scheduled for the evening. He had a first-round bye. At any tournament, a bye is a gift: one fewer fight, more recovery time, an extra light session. Here, it turned into a countdown clock.

Weight in combat sports is a hidden rule that spectators rarely see. People remember the finishing blow, the bell, the medal. They do not remember how long a fighter sat in the bathroom the night before, how many times he spat into a plastic bottle to measure the water leaving his body. For anyone who has followed a national squad through a full season, this is the darkest part of the trade. A fighter's real battle sometimes does not happen on the mat, but in the sauna — and that is a fight with no referee.

The mechanism is simple enough to be dismissed. Under 77 kg means that on the scale, the body must sit at that mark. But between weigh-in and fight there is a window, usually hours to more than a day, for the athlete to eat and drink back up. The deeper a fighter goes below the permitted threshold, the heavier the real weight he carries into the cage against opponents in the same class. That logic creates a bad incentive: cut as much as possible, so long as you can still stand on the scale.

Sanyal chose the fastest route to that mark in a single night: restricting food and fluids, then roughly thirty minutes in the sauna. The result was dizziness, vertigo, muscle cramps, then loss of consciousness. This is the classic chain of acute dehydration: blood volume drops, thermoregulation fails, electrolytes fall out of balance. The body was not "weak" because the athlete was poorly conditioned. The body responded exactly as it is wired to respond.

The prevalence figures for this method are not small. A survey published by the International Society of Sports Nutrition in 2026 found that 79 percent of surveyed fighters restricted fluids to make weight, and 51 percent used sauna as their main tool. In other words, this is not the deviant behaviour of one individual. It is an occupational custom institutionalised by silence.

The same data points to something more worrying: after rapid weight loss, blood creatinine and urea markers often rise. That matters because the Indian delegation's medical team gave Sanyal a preventive blood test and the initial result showed no significant abnormalities. But one draw does not close the file. Dehydration-related kidney stress can appear later, after the body has rehydrated. A "normal" result in the first hour is not a safety certificate for the hours that follow.

At 61, after more than forty years holding a pen, I have learned that reading an event means reading its timeline. Sanyal did not fail in a takedown. He was not knocked out. He lost at the preparation stage — the stage spectators do not pay to watch, and the stage nobody wants to report. Every season has its own heartbeat; you only have to listen carefully. The heartbeat in Aichi-Nagoya those days was not coming from the cage.

There is a detail easily missed. The first-round bye looked like an advantage for Sanyal, but it locked him into a fixed deadline. Had he fought in the first round, he would have been forced onto the scale earlier, and his body would have had more time to recover before the quarterfinal. With the bye, he kept a single day to finish the cut. A physical advantage became time pressure.

That leads to an occupational question rarely raised: does Sanyal actually belong at under 77 kg? When a fighter must push his body to the point of unconsciousness to make a class, his natural frame may well sit one division up. Water cutting is not a neutral tactical skill; it is a gamble on body structure. The winner of that gamble carries a few kilos of real weight into the fight. The loser loses the bout before it begins.

To be clear: the record does not state Sanyal's age, his competitive record, how many bouts he has had, or whether he habitually cuts to 77 kg. There is no data on his style or Nabiev's. Any assessment of in-cage strength would therefore be speculation. The only variable with live data is the weight-cutting behaviour — and that is also the only thing that decided the outcome.

The Indian delegation also hit logistical trouble: the athlete's name was missing from the accommodation system, travel stretched beyond ten hours, and food was lacking before the cut began. Care is needed here. There is no medical evidence that the logistics directly caused the incident; the confirmed causal chain is restricted food and fluids plus sauna, leading to the symptoms. But under-fuelling and fatigue beforehand reduce stored glycogen and baseline hydration, making the same cut more dangerous than it would be in a normal camp. That is a contributing factor, not a proven cause.

The most thought-provoking part lies in governance. Current rules police the endpoint — the number on the scale — not the process of getting there. Fighters are free to do anything to their bodies in the twenty-four hours before weigh-in, provided the needle lands right. The system only punishes those who miss weight. It does not punish those who make weight in the most dangerous way. A rulebook that checks only the result and ignores the route hands a reward to the riskiest behaviour.

At major professional organisations, another approach has been tried: testing urine hydration immediately before weigh-in, and banning sauna and steam rooms outright during the cut. Unfortunately, the record does not say which weigh-in format this Games' MMA event used: same-day, day-before, or with hydration testing. That detail is decisive, because it separates a rule that permits the behaviour from a rule that failed to prevent it.

There is a gap in how the event was told. The Indian Olympic Committee's official statement described it more mildly: cramps and body aches. The sourced account in the Indian Express confirmed the athlete lost consciousness. Two ways of describing the same afternoon. That gap is not trivial, because the severity published shapes how seriously the combat sports community treats the issue. People remember the finish; I remember the sigh behind a closed door.

The easiest reaction is to blame the fighter. He was reckless, he lacked discipline, he hurt himself. That view fails because it ignores the incentive structure. When an entire reward system encourages deep cuts, an individual cutting deep is not anomalous — it is rational behaviour inside a badly designed game. Sanyal phoned the president of the Indian MMA Federation before being hospitalised. He did not hide. He looked for someone accountable.

It is also worth remembering that the withdrawal decision, taken after discussion with his coach, was the correct protective act. A fighter who is medically unfit stepping onto the mat is not an image of iron will. It is medical risk legitimised. Seen that way, being struck from the quarterfinal was not a failure; it was the only moment that day his body was listened to. The arena had no crowd applauding, but I still heard the applause of a man who did not give up.

There is one more layer rarely mentioned. Widely circulated stories of extreme water cutting can normalise the very behaviour at lower levels: amateur gyms, youth squads, where medical supervision is far thinner than at a professional promotion. I live in Nha Trang, where small traditional martial arts schools operate, where boxing gyms run at night, where fifteen- and sixteen-year-olds cut weight for the first time with nobody telling them which threshold is dangerous. The quiet star of Nha Trang never goes out, and I still believe that. But a star only shines while it still has enough water to burn.

What I want to see after Aichi-Nagoya is not a wave of outrage that fades. I want national federations to start asking questions about their own weight-management policy: how many days before a bout fluids are restricted, who supervises, and who has the authority to cancel an entry on medical grounds. I write slowly because I want to remember for a long time, like the man keeping time for the whole field. And there are heartbeats that, once stopped, no season can bring back.
