Grant Denyer, an Australian television and radio presenter, suffered a medical emergency during an episode of The Amazing Race Australia: Celebrity Edition. He collapsed after completing a dance challenge with his wife Chezzi in the humid Indian heat and was taken to an air-conditioned room where he lay on his side on the floor, his face worryingly pale. He displayed symptoms such as dehydration, disorientation, paleness, and low blood pressure, which raised concerns about his health and well-being. Grant Denyer was sick for seven weeks after the incident and was completely bedridden during that time.
