Bottas, 33, prepared for Sunday’s race by sitting in a sauna naked except for a reindeer hat.
The Alfa Romeo driver shared a video on Instagram in which he set the temperature to 100 degrees Celsius and poured water on the coals.
The Finnish star also wrote: “Some call it a warm-up workout, but for others it’s just a daily ritual.”
Bottas has enjoyed a new lease of life since moving from Mercedes to Alfa Romeo earlier this year.

“I just couldn’t understand and accept the fact that in these two years I couldn’t beat Lewis.
