McLaren driver Kevin Magnussen reportedly required treatment on his back due to an overheating seat in the Singapore Grand Prix on Sunday.
The 21-year-old earned a point by finishing in 10th place under the floodlights, but suffered some problems in the process.
According to BBC Sport, the Dane left the race relatively unhurt, but his back was seen to by a doctor due to the heat and his mouth was also burned after his drinks bottle boiled.
"It was hot," Magnussen is quoted as saying. "Really tough. I never experienced anything like this in racing. I couldn't drink water, and the seat was very hot. I still feel dehydrated. I lost a lot of water."
The Formula 1 driver played down concerns by tweeting that reports of burns were "a bit exaggerated, I was just hot and sweaty! #notdead."
Lewis Hamilton overtook Mercedes teammate Nico Rosberg in the driver rankings by winning yesterday's race in Singapore.
