Rafael Nadal took freezing cold shower 45 minutes before every match of his career

Twenty two-time Grand Slam champion Rafael Nadal, who played his last tennis match on Tuesday, took freezing cold shower 45 minutes before every match of his career. "It's the point before the point of no return. Under the cold shower, I enter a new space in which I feel my power and resilience grow," the 38-year-old stated in his autobiography.
