Irish actor Colin Farrell has found a hot new obsession - saunas.

The Total Recall star, who has battled abuse issues in the past, is now clean and sober and reveals steam rooms have become a new addiction.

He tells U.S. talk show host Ellen DeGeneres, "I love sweating... I do fancy the Turkish, Russian bath house... the 10th street baths in the East Village in New York about seven, eight years ago, I started shvitzing and sweating and I've loved it ever since.

"It sweats out the toxins... It feels kind of primal as well in a world that moves so fast and is so about technology. It is something that's ancient and that has stood the test of time and if kind of feels that way."
