Billie recently revealed her top self-care tip. "Listening to your gut is a big one—I know it's not a physical self-care thing, but it's a very important one," she told Harper's Bazaar. "And also, it goes into physical things, like if your gut is telling you to do your face routine right now, then do it. For me, my self-care rituals make me feel so much better. I mean, even yesterday I was really tired and sleepy and felt gross, and I took a shower, did my whole hair and face routines, and I just felt happy after. And it just really made me feel really good. So I would say trust your gut and take care of your body, and it'll make you feel better."

Billie recently revealed that exercise helps get her body prepared to perform "I have been working on my bones and my body for the last — since [getting injured] really," she told Apple Music , referencing spraining her ankle during a show in Milan. "And more seriously for the last, like, four months, I've been like completely changing the way that my life is involving fitness. Like I'm a gym rat now, like when…did that happen? I don't know but it did," she continued. She added that exercise "changed her life" physically and mentally. "I know that's something a lot of people do, but that was not a thing I did. And it's become such an incredibly huge part of my life and it makes me feel so much better as a person and the way that I can move on stage now, I feel so much better."

Eilish also understands the importance of sleep. "It makes the day so much longer," she told Vogue. If she can't sleep, she uses a meditation app. What are the health benefits of sleep? According to the Sleep Foundation, getting enough z's is a mood booster, promotes heart health, regulates blood sugar, improves mental function, restores your immune system, helps relieve stress, and aids in weight loss. 

Billie decided to go vegan in 2014. "There were a lot of reasons," she wrote in a 2018 Tumblr post about why she decided to go meat-free. "I love animals and I just think there's no point in creating something out of an animal when the animal is already there. Leave animals alone. Damn. Also, I'm lactose intolerant and dairy is horrible for your skin and my skin is VERY aware of that."

On the Youtube series Vogue Beauty Secrets Eilish revealed that she used to aggressively wash her face "like a dude," confessing, "I used to wash my face so violently. A friend commented on it one time and she was like 'why are you so rough with your face?'." She has sinced changed her technique. "[You] don't have to do that," she said. "Be gentle, gentle." She also explained that temperature is key. "Don't use warm water, don't use hot water, use cold water," she added.
