The 38-year-old athlete said it's a key part of his longevity routine as he keeps playing at a high level. Emerging research on saunas suggests that Steph Curry says his most important recovery tool isn't a fancy supplement or stretch. When he wraps up a tough workout or intense game, his first stop is the sauna. At 38 years old, on his feet all day running up and down the court, a recovery routine isn't optional. "It's so easy to just skip and be like, 'I'll be fine tomorrow,'" the NBA superstar told Business Insider, but he never does. The sauna, he said, is one of the most essential.
