Collapsed in sauna after weight cut: A costly lesson at Asian Games 2026

Around 9 p.m. on September 19, 2026, at the Aichi-Nagoya athletes' village, Indian MMA fighter Sanyal collapsed after a roughly 30-minute sauna session used for an overnight weight cut. A Nepal athlete helped him, medical staff arrived, and Sanyal was hospitalised. He was later ruled unfit and withdrew from the under-77kg quarterfinal, giving Bahrain's Mukhammad Nabiev a walkover at the Asian Games 2026. According to the Indian Express, Sanyal had a first-round bye and was scheduled to face Nabiev on the evening of September 20. To make 77kg, he restricted food and fluid, then used a sauna for about 30 minutes. He experienced dizziness, vertigo, cramps and loss of consciousness. An initial blood test showed no significant abnormalities, but the IOA's cautious public statement described only cramps and body aches, while sourced reporting confirmed the fighter had fainted. The incident fits the physiology of acute dehydration: reduced blood volume, dropping blood pressure, electrolyte disruption, cramping and syncope. The article cites ISSN 2026 data showing 79% of combat athletes restrict fluids to cut weight and 51% use saunas. PubMed research cited in the story also notes that creatinine and urea markers often rise after rapid weight loss, sometimes later than initial tests. Sanyal discussed the situation with his coach and withdrew. Travel of more than 10 hours, lack of food and an accommodation-system problem are described as contributing stressors, not medically proven causes. The bigger governance question is whether the Games weigh-in process includes hydration testing or only a scale reading. The lesson is clear: weight cutting is not just an athlete's private ritual, it is a medical protocol, a tactical variable and a governance issue.
