Jake Gyllenhaal thinks intimacy is the "best form of self-care"

Speaking to Vanity Fair magazine, Jake said when asked what he does for wellness: "I think it's all bullsh*t if you want it to be bullsh*t, and it's not if you don't. I feel that way about pretty much everything as long as you're not hurting anyone. I believe in sweat, in whatever form.

"For me, my best form of self-care is intimacy; that makes me sweat. And then I believe in the balance of rest and exercise. It's really that simple for me."

However, the 'Prisoners' star swears by a thorough skin care regime because it's been instilled in him from a young age by his older sister Maggie Gyllenhaal.

He said: "Because I have an older sister who is an actor--and because she has taught me since I was a kid and I've looked up to her--skin care is important. People can definitely get me for that, but you'd be laughing your way to wherever. I think caring for yourself is really important, particularly nowadays as men. Being vulnerable and admitting those vulnerabilities is very, very important."

Meanwhile, Jake recently said he's desperate to be a father one day.

He said: "I do hope to be a father one day."

But, for now, he his focusing on his relationship with his two nieces - Ramona, 12, and Gloria, seven - whom Maggie has with her husband Peter Sarsgaard.

In 2017, Jake said: "My sister has raised two extraordinary daughters. They are so well-behaved and they are so thoughtful and so observant of the world around them. I'm so proud of not only them but my sister as a mother.

"When they come to me, I get two great girls, [but] at the end of the day there are times where it's not bad to hand them back."
