I doubt it would have the same result in a warmblooded animal like humans, because only superficial cells would actually reach the effective temperature.

From the article:

By genetically boosting CAT–4 levels in the worms' muscles, the team was able to extend their lifespan even at normal or warmer temperatures, suggesting it's possible to reproduce some benefits of the cold without lowering body temperature.

"We were genuinely surprised to find the supplementation significantly extended lifespan, even at standard and warmer temperatures..."
