Fifty shades of grey...bed sheets. 

At least, it seems that's what Dakota Johnson is into after she recently revealed why getting a good night's sleep is essential for her mental health.

"I'm not functional if I get less than 10," she told WSJ. Magazine in an interview published Dec. 11 for its My Monday Mornings series. "I can easily go 14 hours."

So, how does the Madame Web actress get so much sleep? "I don't have a regular [wake-up] time," she noted. "It depends on what's happening in my life. If I'm not working, if I have a day off on a Monday, then I will sleep as long as I can."

As Dakota put it, "Sleep is my number one priority in life."

The Fifty Shades of Grey alum is also consistent with her wellness routine, which helps her relax and recharge before bedtime.

"I meditate every day, twice a day," she revealed. "I do transcendental meditation. I've been really into breathwork recently and that's been helping me a lot with anxiety."

Another self-care practice she swears by? "I will get in a bathtub at any moment," Dakota shared, "any time of the day. If in the middle of the day, I'm like, 'Oh God, what is this world?' I'll get in the bathtub. I find water really grounding."

Although the 34-year-old—who is the daughter of Melanie Griffith and Don Johnson—has a solid wellness routine, there are moments when she's not in the best headspace.

In fact, she recently shared insight into how her longtime boyfriend Chris Martin has helped her get out of a funk.

"A few weeks ago, I was having a low day," the actress said at the 2023 Hope for Depression Research Foundation luncheon, per Hello. "And my partner said to me, 'Are you really struggling?' and I said 'No?'"

"And he said, 'Baby, you are wearing a Cats T-shirt.' As in Cats the music," Dakota continued. "So it turns out, I really was struggling. But that moment lifted me up and pulled me out of it." 

Finding the humor in those situations also lifts her spirits.

"Most of the time as you can probably tell, I speak about depression or anxiety in a very self-deprecating way," she continued. "Perhaps, I sometimes find it easier to look it in the eyes if I mask it in comedy...Because, sometimes if I don't laugh, I will cry." 

Dakota isn't the only celebrity to speak about her mental health struggles in recent years. Keep reading to see how other A-listers have prioritized their well-being.

The "Treat You Better" singer canceled his summer tour in July, ultimately realizing after first postponing a few weeks' worth of dates that he wasn't ready yet for the demands of touring.

"After a few years off the road, I felt like I was ready to dive back in, but that decision was premature," he wrote on social media, "and unfortunately the toll of the road and the pressure has caught up to me and I've hit a breaking point. After speaking with my team and health professionals, I need to take some time to heal and take care of myself and my mental health, first and foremost." 

Fresh from repeat gold in the halfpipe at the 2022 Beijing Olympics, the athlete told E! News she was taking time off from competition to focus on her mental health—so that when it's time to start gearing up for 2026, the sight of snow doesn't make her sigh (or scream).

"It's just knowing that it could get overwhelming if I just went right back into it into another season," Kim explained. "I'm just basically being a little cautious. I'm just putting myself first and just knowing that I can't handle it right now. I'm taking some time off. I'm going on vacation. It will be good."

The Rhode skincare founder has found therapy to be helpful when it comes to keeping her head in the game, personally and professionally.  

"It's something that I felt not sure of in the beginning," the model said on her YouTube channel in honor of Mental Health Awareness Month in May. "But the more I've grown my relationship with my therapist, it has been such a game changer for me and it's a space where I feel really safe to be able to talk about what's going on in my mind, say things out loud and feel safe and not feel judged."

She also has set social media boundaries for herself, telling Harper's Bazaar in 2021 that she reserves her scrolling for non-business days. "I had to start doing this thing where I don't go on Instagram Monday through Friday," Bieber explained. "If something needs to be posted, I have somebody who I work with who runs it for me. I had to remove myself."

The American Idol judge went almost four years between album releases before dropping Witness in June 2017—and when asked what she'd been up to in the interim, she told E!'s Ryan Seacrest at the Grammys that year, "It's called taking care of your mental health."

Reflecting in 2020 on how much she needed that break, she told CBC Radio host Tom Power, "My career was on this trajectory where it was going up-up-up-up-up-up-up, and then I had the smallest shift. It wasn't that huge, maybe, from an outside perspective, but for me it was seismic. It literally kind of broke me in half. I think I had broken up with my boyfriend, who's now my baby daddy-to-be. And then I was excited about flying high off the next record and the record didn't get me high anymore…The validation didn't get me high, and so I just crashed."

But, Perry added, "It was so important for me to be broken, so that I could find my wholeness in a whole different way, and be more dimensional than just living my life like a thirsty pop star all the time."

The two-time Grand Slam champion sent shockwaves through Roland Garros when she informed French Open organizers in 2021 that, just a few months after winning the Australian Open, she wouldn't be sitting down with members of the media during the two-week event in Paris, citing the toll those encounters took on her mental health.

Her polarizing decision—the post-match press conference, win or lose, is usually part of the routine for top players and they get fined for skipping them—threatened to be the talk of the fortnight, so she ended up pulling out of the tournament entirely. But though she later acknowledged she may have handled certain things differently in hindsight, she made the decision based on how she was feeling at that moment.

"Like whatever I feel, I'll say it or do it," she told reporters before the U.S. Open last September. "I don't necessarily think that's a bad thing. I think there's a lot of things that I learned to do better. Of course, I don't feel the same situation will happen again."

If there was anything to do differently, she added, "I would say maybe think it through a bit more in the way that, like, I didn't know how big of a deal it would become."

After wrapping the role of her lifetime to date, playing Princess Anne on The Crown, Doherty said her mental health "did dip"—leading her to realize she had a different kind of work ahead of her.

"To sit in my own thoughts was a difficult process at first," she told Grazia in 2020 of experiencing such a drastic swing in her schedule, "because you tune in with where your body and your mind and your soul and your spirit are."

"Part of that process is going, 'Right, I really need to look at this, because I don't feel very happy about that,'" she concluded, "or, 'I really haven't addressed these issues that may have been there since childhood.'"

The less time spent online, the merrier for Gomez, who sought treatment for her mental health in 2016 after wrapping her Revival World Tour.

"I haven't been on the Internet in 4-and-a-half years," the Only Murders in the Building star said on Good Morning America in April. "It has changed my life completely. I am happier, I am more present, I connect more with people. I understand how powerful the Internet is, and in so many ways it's done the best things for the world. But for me, I get to my news that is actually important I get through people in my life."

Keeping her own accounts at arm's length hasn't deterred her 344 million-and-counting Instagram followers.

And who isn't (or should be) taking a break from social media at any given time? On Aug. 15, Marvel superhero Tom Holland and three-time Olympic gold medalist Gabby Douglas shared that they needed to get off the apps for their own good.

"I get caught up and I spiral when I read things about me online," Holland explained. "And ultimately, it's very detrimental to my mental state. So, I've decided to take a step back and delete the app." 

And whether their time away proves temporary or so replenishing they decide to stop scrolling long-term, they join a group that includes Cole Sprouse, Margot Robbie, Will Poulter, Ed Sheeran, Jennifer Love Hewitt, Bindi Irwin, Eva Mendes, Camila Cabello and many more who've worked digital detoxes into their wellness regimens over the years.

The tennis champion, who shared in an August 2022 essay for Vogue that she's evolving away from her sport toward other priorities, said that the key to maintaining her mental equilibrium is setting boundaries and taking time, however brief, for herself alone.

"Mental fitness for me is just really learning to shut down," Williams told Gomez in a conversation for the actress' Wondermind initiative. "And you know I did this years ago, before even mental health was a topic among everyone's mind. It was more just like, alright, I'm shutting myself down today. Just subconsciously, it was something I've always done. And so now that I know that it's so important to just put yourself first, especially mentally, I always have shut-down moments. I have serious boundaries and I don't let anyone cross those boundaries."

Easier said than done, especially now that she's a mom, so she's "still working on it," the athlete admitted.

Living so much of her life in the public eye, on purpose, D'Amelio told E! News that her professional content obligations make it all the more important that she keeps the particulars of her relationship with Noah Beck to herself.

Doing so is "much healthier for both of our mental health," she said at the opening of the Social Tourist pop-up in June. "Our relationship is better. It's just so much more fun when you're not worrying, 'Oh my god, wait. You need to like my picture right now,' or because people are saying that we hate each other because we didn't do this or whatever."

She also realized that having a super-harsh reaction to someone's random online comment tends to be an indicator that something is off with her.

"I've seen the difference from when I'm mentally healthy versus not," D'Amelio explained. "When I'm healthy, I could read a comment and it doesn't mean anything to me. But if I read a comment and it freaks me down for three days, I realize that something is going on and I need to look deeper than people are just being mean online."

"I feel like it's a lot of reflecting on yourself and thinking how you're feeling," she concluded, "and it's an important conversation we need to continue having, and it's a journey."
