Australian actor Cate Blanchett revealed she's a fan of a good old fashioned colonic cleanse.

"I think it's good every now and then to have a colonic," she told Yahoo Beauty. "Not every day, but every now and again, because it's super hydrating."

Her other wellness tips include "don't drink, don't smoke" and get plenty of sleep.

The 46-year-old also talked about her disdain for social media.

"The like and the dislike is just totally primary schoolyard. I cannot for the life of me work out why adults are participating in that s**t," said Blanchett.

She said it's "pathetic" when people take selfies and worry about what other people think of them.

"I just can't handle it. Of course you want people to go see the films that you make, of course you want them to enjoy them. But I'm not out there saying, 'Do they like the way I look? Do they like that look on the red carpet?' You have to say, 'This is what I'm doing right now,"' she said.

Blanchett is not on social media, for better or worse.

"I probably do miss out on a lot of stuff - I probably go to less parties than I would like," she said.

Her film Carol will premiere in Australia at the Adelaide Film Festival on October 18 and in New Zealand next year on February 11 .
