The Seawater Cure: How the French Slim Down
A food-and-wine writer from the U.S. describes his annual pilgrimage to the Normandy Coast for thalassotherapy—a round of treatments that’s proven to be an antidote for his occupational overindulgence.

AS A food-and-travel writer who lives in France, I face occupational hazards other people might envy: Think white Burgundies, foie gras, butter, cream and the world’s best cheeses. It’s a constant battle to avoid ending up with the silhouette of a pear.
That’s why in the years since I moved to Paris in 1986, I’ve become a fan of thalassotherapy, taking dozens of “cures” at some of the 50-odd thalassotherapy centres along the Atlantic and Mediterranean littorals of France. The word derives from the Greek words “thalassa” (sea) and “therapeia” (to nurse or cure) and refers to a series of treatments—heated seawater baths, stimulating jet showers and seaweed wraps—and exercise such as aqua gym (in-water calisthenics).
While these cures alleviate the fatigue and sluggishness I feel after months of late-night dinners and deadline pressure, I’ve found that a weeklong thalassotherapy circuit that includes low-calorie meals also contributes to a healthier, slimmer, better-toned me. Apparently, Plato believed “the sea cures all human ailments,” but my goal is simply to retreat, relax and, at the end, be able to tighten my belt to its customary notch.
A thalassotherapy experience can be completed in as little time as a weekend, but a typical stay lasts 5-7 days. A 6-day signature cure with room and board and four treatments a day costs about $1,580 at Thalazur in Cabourg, a well-mannered Belle Époque seaside resort in Normandy. It was there I booked my most recent extended cure in February, 2020.
I’d heard of Cabourg as a favourite escape of Marcel Proust, who stayed at the Grand Hôtel and, by his account, would gaze at the flinty waves of the English Channel while enjoying his favourite sole Normande (sole poached in cider with a rich cream sauce garnished with button mushrooms, shrimp and mussels).
The centre is a brisk 10-minute walk from the heart of Cabourg with its fan-shaped street plan spreading out from the casino and the Grand Hôtel. Even if my low-calorie regimen barred me from indulging in sole Normande, I never felt gastronomically deprived as I enjoyed a healthy menu with tasty choices such as freshly shucked Norman oysters and steamed salmon with spinach.
My pleasantly monastic existence found me donning a terry cloth bathrobe and slippers every morning and reporting for my daily program of five treatments. Administered by cheerful spa attendants in individual white-tiled spa cabins, these averaged 25 minutes each. While the seaweed jet baths were blissfully relaxing, the high-velocity jet showers, an attempt to pummel the cellulite out of you and improve circulation, were more of a “grin and bear it” prospect.
I can’t pretend I loved the wraps either: Slathered in puréed seaweed, swathed in huge sheets of plastic film and then covered with a heated blanket, I felt like I was being mummified. This detoxification process promises to rid you of “water weight,” and your parched skin receives a good dose of seaweed’s moisturising oligo elements, but I inevitably developed an itch somewhere I couldn’t scratch. Still, when the slick plastic was stripped away and I could shower, I felt hugely invigorated.
More alarming, I also endured cryotherapy. The attendants locked me in a capsule of dry air cooled to -230 degrees Fahrenheit for three minutes, an experience meant to improve circulation and increase production of cortisol, collagen, endorphins and adrenaline. The adrenaline rush, at least, was real; it was a profound relief to exit my capsule after being subjected to a blast of Arctic chill while wearing nothing more than black paper spa panties.
These morning regimens induced a languorous exhaustion, so I inevitably followed up the light lunch with a nap in the afternoon. Then, refreshed, I took long walks on the beach or bicycled along the promenade in front of the hotel.
Memories of my stay—and the 7 pounds I dropped there—prompted me to test the waters again last winter. I booked a 1-night, 2-day weekend sampler at the Thalazur in Port Camargue on the Mediterranean, an hour from my house.
This centre was smaller but also had lovely sea-views, plus my stylish sea-shack style room came with a large private balcony. The three treatments a day were excellent, too; the cost, about $178, was worth it for the belt-tightening.
When, on the Monday after my return home, I went to the single-window post office in my village, the post mistress raised her eyebrows theatrically. “Bonjour!” she said with a grin. “What happened!? You look great!” I went for a weekend of thalassotherapy, I told her. “Ah, voilà! La Thalasso fait toujours du bien,” she purred.
She was right, of course. I look forward to a week-long saltwater wallow this winter, maybe in Bandol with its views of the Mediterranean, or at the elegant new Relais Thalasso in the seaside town of Pornichet on the sunny Atlantic coast in the Loire region. Unlike at other centers, where you traipse about between treatments, the Relais Thalasso crew stash you in a spacious private suite with a comfy lounge area, the better to nap before another go-round.
Water, Water, Everywhere
France pioneered thalassotherapy but you can find excellent centers in other countries, too
La Perla, Spain
For the uninitiated, La Perla, a stylish centre in San Sebastián in the Spanish Basque Country, is a great place to sample thalassotherapy before committing to a full-on cure. Originally established by Spain’s Queen Maria Cristina, when she was queen from 1829-1833, at the royal family’s summer house here, the spa was rebuilt in 1912 on a site overlooking La Concha, a crescent-shaped beach. A 5-hour day pass gives you access to a hydrotherapy pool, water beds, marine steam baths and an in-water exercise circuit. Another option includes a massage and lunch in the spa’s restaurant overlooking the sea. From $49 for a 5-hour day pass.
Vilalara Longevity Thalassa and Medical Spa, Portugal
Vilalara Longevity Thalassa and Medical Spa in Lagoa, a city in Algarve, Portugal’s southernmost region, is set in lush gardens overlooking the Atlantic. It has two seawater pools, 20 treatment cabins and a variety of cures, including a 5-night detoxification program with 2 thalassotherapy sessions per night, lymphatic drainage massages, access to thalasso pools and a consultation with a nutritionist to personalise a tasty low-calorie meal plan or a liquid diet of anti-inflammatory shakes, juices and soups. From about $3,899.
Divani Apollon Palace and Thalasso, Greece
Situated on the Athenian Riviera, this world-class spa in the Divani Apollon Palace and Thalasso outside of Athens boasts the largest thalassotherapy pool in Greece with 16 different water jet areas in its expanse. The X factor at this family-run beach-front property with 25 treatment rooms is its healthy low-calorie menu created by the hotel’s chef and in-house dietician. Appetising proof that shedding pounds needn’t mean privation: the zucchini-crust Greek pizza with anthotryo (fresh cheese), cherry tomatoes, oregano and EVOO. From about $1,747 for a 3-day stay.

Sydney Children’s Hospitals Foundation CEO Kristina Keneally says Australia’s culture of large-scale philanthropy is becoming more sophisticated as Gold Dinner raises $75.5 million for children’s health, research and innovation.

Australia’s wealthiest donors are becoming more strategic, more ambitious and increasingly focused on creating measurable impact, according to Sydney Children’s Hospitals Foundation chief executive Kristina Keneally.
Speaking after the 2026 Gold Dinner, held last week in Sydney, Keneally said Australia was experiencing a significant shift in how major philanthropy is viewed, with large-scale giving increasingly part of conversations about leadership, legacy and social impact.
The annual Gold Dinner, now in its 29th year, brought together some of the country’s most influential business leaders, philanthropists and cultural figures, raising $75.5 million and counting in support of the Sydney Children’s Hospitals Network.
While the event has become one of Australia’s most prestigious fundraising gatherings, Keneally said its significance extends far beyond a single evening.
“Gold Dinner, the flagship event of Sydney Children’s Hospitals Foundation, represents far more than a single evening. It is a powerful demonstration of what a committed community can achieve together over 12 months,” she said.
“The strength of that community, and the trust built over nearly three decades, means people return not just for the event, but for the impact they know it delivers.”
A NEW ERA OF PHILANTHROPY
Large-scale philanthropy has long been a feature of American society, where charitable foundations and major donors often play a prominent role in funding medical research, education and social programs.
Keneally believes Australia is moving in a similar direction.
“Australia is building a stronger culture of large-scale philanthropy, but it is still evolving compared to the United States, where giving at scale is more deeply embedded and widely recognised,” she said.
She said the country’s philanthropic landscape was becoming more sophisticated as successful business leaders increasingly sought opportunities to create meaningful change through their giving.
“In Australia, while generosity has always been strong, large-scale giving has historically been less visible, but that is changing rapidly as more leaders embrace philanthropy as a powerful way to drive meaningful outcomes.”
According to Keneally, events such as the Gold Dinner are helping reshape public perceptions of philanthropy by demonstrating the tangible outcomes that major donations can achieve.
“Gold Dinner is helping to reshape how philanthropy is perceived in Australia, making it more visible, more aspirational and more connected to real-world outcomes,” she said.
WHERE THE MONEY GOES
The funds raised through Gold Dinner support clinical care, research and innovation across the Sydney Children’s Hospitals Network.
Over the past 12 months, more than $75.5 million has been raised to help fund advanced medical equipment, innovative care models and world-leading medical research. Areas of focus include precision medicine and early diagnosis, where emerging technologies are already changing how childhood illnesses are detected and treated.
Keneally said the impact is felt directly by children and families facing some of the most difficult moments of their lives.
“For children and families, this translates into very real and immediate impact. It means faster diagnoses, earlier access to life-saving treatments, and care that is more personalised and effective,” she said.
“It also ensures hospitals are equipped not just to respond to illness, but to reimagine what care can look like, giving children the best possible chance not only to survive, but to live full, healthy lives.”
BUSINESS LEADERS BACKING CHANGE
One of the defining characteristics of Gold Dinner is the calibre of its supporters.
The event has evolved into a meeting point for influential leaders from business, culture and philanthropy, many of whom see charitable giving as an extension of their professional and personal legacy.
“It speaks to a community that is not only generous, but increasingly ambitious in how it gives, combining influence, expertise and purpose to achieve outcomes at scale,” Keneally said.
Among the major supporters of this year’s event were Presenting Partner, John-Paul Nassif Foundation; Major Partners, ABC Bullion, Shaw and Partners Financial Services and One Circular Quay by Lendlease; and Premier Partner, Range Rover, whose ongoing support reflects a shared philosophy of legacy and long-term impact.
The evening also featured performances, premium hospitality experiences and fundraising initiatives designed to encourage further support for children’s health services and research.
LOOKING BEYOND NEW HOSPITALS
With major new children’s hospital developments at Randwick and Westmead progressing, Keneally said the focus is increasingly turning towards what comes next.
“The long-term vision is to ensure every child has access to world-leading healthcare, care that continues to evolve through innovation, research and global collaboration,” she said.
The foundation’s future priorities include accelerating medical discovery, expanding access to cutting-edge treatments and helping position New South Wales as a global leader in children’s health.
Keneally said the Gold Dinner remains central to achieving those ambitions because it does more than raise money.
“Gold Dinner is critical to making that vision possible. It not only provides significant funding, but also unites a powerful network of supporters who are driving the future of philanthropy in Australia,” she said.
As Australia’s culture of philanthropy continues to mature, Keneally believes that the network will play an increasingly important role in shaping the future of healthcare for generations to come.
“The result is a community that is helping to shape the future of paediatric care, not just for today’s patients, but for generations to come.”
