While most NASCAR drivers are wilting under brutal summer heat, Ricky Stenhouse Jr. is thriving. The Mississippi native believes his childhood in the humid South gave him an edge that’s paying off when cockpit temperatures soar and other drivers struggle to stay sharp.
The extreme heat continues to test NASCAR drivers across summer race weekends. While many drivers battle exhaustion and dehydration during long, caution-free runs, Stenhouse claims he is largely unfazed by the heat.
Why Does Ricky Stenhouse Jr. Skip Cooling Suits When Others Can’t Survive Without Them?
With more and more NASCAR drivers expressing concern over the sport’s physical demands, especially with cool suits not being enough at times, Stenhouse is leaning into the heat. In fact, he even welcomes it.
In a recent post on X, Stenhouse revealed that he has chosen to ditch cooling suits altogether, citing reliability issues. “This is why I don’t wear one,” he said. “They break more than they work. Hot water on you is no good.”

“I think for me it was growing up in hot and humid Mississippi,” Stenhouse explained on SiriusXM Radio. “I love the heat and I hate being cold, so it’s just been who I am for a long time.”
How Does Stenhouse Jr. Train His Body for Extreme Heat?
Growing up in Olive Branch, Mississippi, and early exposure to Southern humidity gave Stenhouse an edge. His childhood helped train him for what has become one of NASCAR’s most underrated challenges: surviving the heat inside the car without cooling suits.
Stenhouse added, “I will say, being gone from Mississippi and then going back in the summer a couple of times, it is hotter than I remember. So maybe that really did play a factor into me liking the heat.”
While other drivers mainly rely on technology and climate-controlled training to prepare for the soaring temperatures in the cockpit, Stenhouse takes a different approach.
“I do sauna training as well,” he said. “I work out in my gym with no AC two or three days a week. So I do things that help with being in the car when it’s hot and humid.”
NASCAR drivers wear cooling suits as part of their safety equipment. These suits are designed to help regulate their body temperature while behind the wheel during the scorching hot summer races. The suits normally consist of a shirt with tubes that circulate cold liquid, helping to keep the driver cool. Hence the name, ‘cool shirt’.
As cockpit temperatures continue to rise and driver fatigue becomes a growing concern, Stenhouse’s conditioning strategy stands out. While others struggle with the heat, Stenhouse’s comfort in hot conditions is both a personal trait and a strategic advantage in a sport where endurance is sometimes overlooked.
As the calendar moves into more high-temperature summer races ahead and questions around the effectiveness of cooling suits continue, Stenhouse’s ability to stay sharp in extreme conditions puts him in a unique position during a grueling NASCAR summer.
