Cindy Crawford, Halle Berry, Julianne Hough swear by this steamy wellness trend

Over the past few years, an increasing number of stars have spoken out about the health and beauty benefits that they have experienced from frequent sauna sessions. 

As the New Year dawns, here's a look at the stars who are using Hollywood's hottest self-care hack. 

In June 2024, Hough posted a video with the caption "Six Senses Sizzling Sauna Stretches" that was taken during a vacation at Ibiza's Six Senses Resort in Spain. In the clip shared on Instagram, she displayed her fit physique in a brown string bikini while showing off a series of stretching and Pilates moves. 

Contrast therapy treatment involves alternating between hot and cold temperatures to stimulate circulation and reduce inflammation. The rapid temperature changes are known to relax muscles, decrease soreness and promote overall physical and mental recovery.

"I've been doing ice baths since 2015 when I was touring the country on stage for 2.5 hrs almost every night," Hough wrote in the caption. "In 2014, I had the worst neck injury the whole tour that I just couldn't fathom the pain and pure survival mode again verses being able to fully enjoy being on stage night after night. So I committed and never looked back!"

"The amount of recovery I have spent on my body in my later years of life would've been much less if I had known about the benefits of contrast therapy earlier," she explained. 

Hough concluded her post by sharing her best tips for those who want to try contrast therapy.

"If you feel the water is hurting your toes or fingers, you can wear booties/gloves or like I do, I hold my fingers out of the water," she wrote.

"Another hint: pick a song that you LOVE that's around the length that you want to stay in so you can groove to it. My go to songs are 6's to 9's and Calm Down."

In 2015, the 59-year-old supermodel told Byrdie, "I try to go into an infrared sauna for 20 minutes at least once a week. Before I invested in my own, I just went to a local tanning salon that also had an infrared sauna - my homeopathic doctor suggested I get one because it's good for detoxing." 

"Another added benefit? Twenty minutes of uninterrupted time to read!"

In August, Crawford shared a glimpse at one of her favorite pastimes, posting a photo in which she was seen topless and makeup free while reading a book in a sauna. 

"Sauna time and a good book = perfect morning," she wrote in the caption.

"Baby hairs in the sauna," she wrote in the caption. 

Kim Kardashian celebrated her love for saunas as she posted photos of herself enjoying a session in 2023.

"It's not always rainbows and butterflies…sometimes it's rainbows and saunas," she captioned her post, adding emojis of a rainbow and a fire. 

In a post on her Goop blog, Paltrow wrote about enjoying the Clearlight Infrared Sauna that she had installed in her Montecito house. 

"We'll take an infrared heat fix anywhere we can get it," Paltrow wrote. "But having a sauna right at home is the real dream."

"I do an infrared sauna as often as I can," she added. "I walk out feeling so much more relaxed, and glowy, too."

"I love sauna-ing," Paltrow said. "And if I'm on the go, there's this infrared sauna blanket by HigherDose that is a 10 out of 10."

"You just get in it, and you sweat," she added. You can be on your phone, or you can put your arms underneath, which is what you're really supposed to do, and just chill, meditate, or listen to a podcast.

"Getting my pre-Christmas schvitz on in a miraculous @clearlightsaunas100 #healwithheat. I love this thing," she wrote in the caption.

In 2021, the wellness technology company Sun Home Saunas shared a photo of a bikini-clad Paltrow using one of their at-home saunas.

"The one and only @gwynethpaltrow enjoying her session in our Sanctuary Infrared Sauna!" the company wrote in their Instagram post. 

The 59-year-old actress shared a photo in which she was seen lying naked in a dry sauna with two towels strategically placed over her chest and lower body. 

"Embracing the healing power of the sauna and sweating out the stress this #WorldWellbeingWeek," she wrote. 

In 2023, the 47-year-old singer uploaded a carousel of images featuring herself in a white bikini with a twist tie top while at the spa. 

"Let discipline carry you when motivation won't.
