Where to cold plunge in Chelsea

Cold-water evangelists are easy to spot. Mention sleep, stress, ageing or a fairly ordinary Tuesday and, somewhere before the wine arrives, you will be hearing about dopamine, immunity and Andrew Huberman — Stanford neurobiologist, podcaster and high priest of the protocol of deliberate discomfort. The longer-serving converts will add Wim Hof, the Dutchman known as the Iceman, who was sitting in ice long before anyone made a podcast about it. Chelsea has joined the congregation: there is cryotherapy at KXU on Pavilion Road, an eight-person plunge at Third Space Chelsea, four ice baths at ONE LDN in Fulham, and Third Space Battersea will have two new baths filled and ready for Contrast Therapy by December.

If you are cold-curious rather than cold-converted, there are several levels of commitment within reach of Sloane Street. Here’s where to find them, the reasons to take the plunge, and the rules from the people who wrote them.

The post-plunge buzz is not in your head, or rather it is, chemically. In the study everyone quotes, young men sat in 14°C water and their dopamine rose by 250 per cent and noradrenaline, the alertness chemical, by 530 per cent. They sat there for an hour, which nobody recommends and nobody in Chelsea has time for. A short plunge sets off the same chemistry: Huberman puts it at one to three minutes in water cold enough to make you want to get out, for a lift in mood and focus that lasts hours.

The longer payoff is the one the converts talk about most: resilience, the idea that a small, chosen dose of discomfort each morning makes the day’s unchosen ones easier to meet. Chris Ballard, the Sports Illustrated writer who took up ice swimming for his book The Plunge and ended up swimming for the US at the world championships, notes that five days of exposure is enough to halve the gasp: the body learns fast. What kept him going was simpler. “When you’re in that cold water,” he says, “you’re really only present in that moment.”

The lift comes first and the calm comes later. A 2025 review of 11 trials found that stress levels fell about 12 hours after a cold dip, so a morning plunge pays out at bedtime, and that sleep and quality of life improved with it.

Then there is the claim every convert makes sooner or later: they never catch colds any more. The best evidence for it is Dutch. When 3,018 people in the Netherlands ended their daily shower with 30 to 90 seconds of cold for a month, they took 29 per cent fewer sick days than people who stayed warm. And in a 2014 study, researchers at Radboud University taught 12 healthy men Hof’s method of breathing, meditation and ice baths for ten days, then gave them, and 12 untrained men, a small dose of bacterial toxin that mimics an infection. The trained group produced more of the body’s own anti-inflammatory chemicals, and produced them faster: evidence that a system long assumed to run on autopilot could be steered. Hof’s followers have been quoting it ever since.

If your week has padel, intervals or a long run in it, cold water is on your side, and the sooner the better. A 2022 review of 52 trials found that after hard, fast exercise, people who got into cold water were less sore the next day, felt more recovered and had their spring back sooner than people who simply lay down; the follow-up found it beat the warm bath, the gentle cool-down and hot-and-cold for easing soreness.

Weights are the exception. A strength session leaves the muscle fibres with tiny tears that knit back slightly thicker over the next day or two, and very cold water straight afterwards muffles that repair: a 2024 review found that plunging immediately after lifting blunted muscle growth. If muscle growth is the aim, Huberman suggests waiting six to eight hours between the weights and the water, or plunging before you train instead.

You can start tonight. The Dutch cold-showerers found 30 seconds worked as well as 90, and the benefit they mentioned most was energy, with many comparing it to caffeine. It takes less time than deciding against it.

The face dunk is the trend’s domestic edition: a bowl of iced water, a held breath, face in. The calm the converts swear by has real physiology behind it. Cold water on the face, with the breath held, sets off the diving reflex, the body’s built-in brake, which slows the heart almost at once. It’s why a bowl of iced water has become the fix for a racing mind before a big meeting.

Women get the benefits on easier terms. Dr Stacy Sims, the exercise physiologist whose work on female athletes is the standard reference, points out that women cool faster than men, so the plunge does its work sooner: around 14–15°C for two to five minutes, rather than the near-freezing endurance test of the Instagram ice bath. One footnote: only one of the 11 trials in the 2025 cold-water review included women.

The best evidence came from women who didn’t wait for the trials. When a UCL team asked 1,114 cold-water swimmers what the habit did for them, the 785 going through the menopause were emphatic: less anxiety for nearly half, fewer mood swings for a third, fewer hot flushes for three in ten. Many said the company on the beach mattered as much as the cold.

And the cold needn’t be a plunge at all. Craig Heller, Stanford biology professor and a world authority on how the body regulates heat, put a class of first-year women, none of them athletes, through press-ups: ten sets to failure, with their palms cooled for three minutes between sets. The palms, like the soles and upper face, carry blood vessels that shed heat unusually well, so cooling them let the muscles keep going. Over the study, some built up to more than 800 press-ups in a session, and their only complaint was that they’d all had to buy sleeveless dresses for the formal. Heller tested women on purpose, because everyone assumed the effect ran on testosterone. It didn’t.

KXU
What: The cold without the water

Address: 241 Pavilion Road, SW1X 0BP

Third Space Chelsea
What: The plunge with a full contrast circuit
The vibe: A marble-tiled wet spa just off the King’s Road, with a Finnish sauna, steam room and a plunge at 8–10°C wide enough for eight, so the bracing is done in company. Cowshed in the changing rooms for afterwards.
Address: 19 Mallord Street, SW3 6AP

Third Space Battersea
What: The plunge with a power station attached
The vibe: Reclaimed brick, a 20-metre pool and a sunken Finnish sauna in the shadow of the chimneys. From December, Battersea Studios two minutes away adds two ice baths and a dry sauna for 17.
Address: Ground Floor, Prospect Way, Battersea Power Station, SW11 8BH

ONE LDN

How much. About 11 minutes of cold a week in short dips, and 57 minutes of sauna in sessions of 10 to 15, spread over two or three visits. Longer isn’t better. The figures come from Susanna Søberg, the Danish scientist whose study of Copenhagen winter swimmers Huberman built his protocol around.

How cold. Cold enough that you want to get out, but can stay safely for the time you planned. For beginners, Huberman suggests around 13–16°C, working down from there. Women: stay at 14–15°C, says Dr Stacy Sims.

Set the timer, then obey it. Decide your time before you get in. The dopamine makes you overestimate yourself, so when the timer goes, get out. Andrew Huberman.

No breathwork in the water. Wim Hof’s breathing exercises are for the sofa, never the plunge: his own safety guidance warns against doing them before or during swimming or bathing, which is also why Huberman says no deliberate hyperventilation before you get in.

End on cold. After the sauna, finish in the plunge so your body has to warm itself back up. Huberman calls it the Søberg principle.

Don’t flail. According to Heller, if you sit still, a thin layer of water next to your skin warms up and works like a blanket. If you thrash about, you keep replacing it with cold water. 

Cool the hands, not the neck. The body sheds heat through the palms, soles and upper face. An ice pack on the neck is, in Heller’s words, like putting a wet flannel over your thermostat: you feel cooler while your core stays hot. Cool rather than icy, or the vessels clamp shut.

Plunge before a hot run. Heller says a few minutes of cold before a long run in the heat gives the body more room to absorb it, so you reach the sweat point later.

Not alone, feet first, and check with your doctor. Cold water makes the heart work harder and sets off an involuntary gasp, which is why the RNLI treats anything under 15°C with respect: have someone with you the first time, and lower yourself in rather than jumping. 

Wim Hof’s own safety guidance says not to practise while pregnant and to see a doctor first if you have a heart condition; the same applies to uncontrolled high blood pressure, Raynaud’s and cold urticaria.
