Last month, Dillon raced to his third career win at the NASCAR race in Texas. In a post-race Zoom call after the win, the driver recalled experiencing dehydration.

“I got a couple IVs in me, feeling great. I felt great once I kind of got in air conditioner. I was wanting to come back out because it stinks to win the race and you’re falling out,” Dillon said when finally on his postrace Zoom call. “But I gave it all. I left it all out there. At least I can say that, and left it all on the track.”
