Sitting in an ice bathtub for 3 minutes a day, 5 days every week, is an unconventional remedy that the no-nonsense Holby Metropolis character, Dr Jac Naylor, is unlikely to have endorsed.
However actress Rosie Marcel, who performed the guts surgeon within the fashionable BBC drama for 16 years, is a devotee of the freezing dips to deal with the ache attributable to her uncommon autoimmune situation.
‘I’m going numb once I’m within the ice bathtub – however you shortly get used to it,’ says Rosie, 46, who lives in Hertfordshire together with her husband, Ben, 41, who owns a fitness center, and their daughter, Beau, eight.
‘After I get out of the ice bathtub my pores and skin’s shiny pink. However then the endorphins and dopamine kick in – and I really feel unimaginable.’
Rosie takes ice baths to ease the signs of Behcet’s illness, an agonising immune situation that causes painful pink lumps all around the physique.

Behcet’s syndrome, as it is also recognized, is attributable to an over-reaction of the immune system, regarded as resulting from a mixture of genetic, immune and environmental components. In addition to swollen lumps, signs can embrace painful mouth and genital ulcers, stiff and painful joints, eye irritation (leading to pink eyes and blurred imaginative and prescient) and hypersensitive pores and skin.
Remedies embrace steroids, immunosuppressants and biologic medicine (constituted of human or animal proteins, which cut back irritation), to ease signs.
In Rosie’s case it causes outbreaks of ‘painful laborious, pink lumps’ throughout her legs, ‘ranging in dimension from a 5p piece to a tennis ball’ in addition to ‘a great deal of mouth ulcers’.
First identified with the situation in her 20s, she had been taking immuno- suppressants for almost 20 years, however with side-effects equivalent to an elevated danger of infections (Rosie says she was continually in poor health), she determined to check out ice baths after studying in regards to the potential advantages on social media.
Historically used for hundreds of years in Scandinavia and Russia for his or her ‘therapeutic’ properties, ice baths have turn into a social media pattern, popularised by Wim Hof, an endurance athlete who as soon as held the Guinness world document for swimming beneath ice.

Ice baths – actually bathtubs filled with icy water starting from 0c to 15c – can be found in gyms and spas, however can be purchased for dwelling use. Some folks resort to filling wheelie bins with ice, in accordance with social media websites.
However whereas ice-bathing could promote emotions of elation and wellbeing, can it actually profit your well being? And what in regards to the dangers?
The scientific proof for his or her advantages is way from conclusive.
Definitely, in relation to muscle restoration, the case is stronger, and elite athletes equivalent to runners and footballers have lengthy used cold-water immersion remedy (together with ice baths and cold-water swimming) after intense coaching periods – it helps ease muscle irritation.
A evaluate of 17 trials (through which the water temperature was 15c or decrease) by the celebrated Cochrane group concluded that the apply did cut back muscle soreness — however stated extra analysis was wanted as to its security.
One other, more moderen, evaluate revealed final yr within the journal Sports activities Drugs, discovered cold-water immersion remedy was efficient after high-intensity interval coaching (HIIT) amongst folks deemed bodily lively or concerned in sport. These utilizing it reported higher muscle energy and fewer soreness 24 hours after exercising than those that simply rested. Researchers famous that colder temperatures after HIIT could be more practical at eradicating the enzyme creatine kinase, a marker of irritation.
Past muscle restore, a 2022 evaluate of 194 research of cold-water swimmers, ice swimmers and ice-bath customers discovered they skilled a spread of well being advantages together with potential weight reduction, discount of blood fat and higher management of blood sugar ranges.
The researchers urged one motive for this could be as a result of chilly water prompts the physique’s shops of ‘good’ brown fats, which burns power within the type of fats to maintain the physique heat, and helps regulate blood sugar and fats metabolism. (Against this, white fats, which makes up the best proportion of fats in your physique, shops power as fats.)
One of many evaluate’s authors, Professor James Mercer from the College of the Arctic Circle in Troms, Norway, instructed Good Well being that it was laborious to attract particular conclusions as there was a lot variability between the research.
Though the folks he meets who use cold-water remedy all ‘swear by’ its advantages, he provides: ‘The jury remains to be out by way of the science behind cold-water immersion and extra high-quality analysis research are wanted’.
Any well being advantages could stem from the physique’s response to the chilly, explains Dr Mark Harper, a marketing consultant anaesthetist at Brighton and Sussex NHS Belief, and the writer of Chill: The Chilly Water Swim Remedy.
He says: ‘What occurs initially is that your physique tries to guard itself towards the chilly, so all of the blood vessels supplying the pores and skin, shut up, and the physique as a substitute concentrates on offering heat blood to the very important organs.’
He provides that irritation ranges drop over time because the physique adapts to cold-water immersion remedy.
Individually, cold-water swimming is being trialled as a possible remedy for melancholy.
Led by Dr Harper, the research – which is beneath means at Portsmouth College – will examine out of doors swimming with commonplace remedy for melancholy in 400 volunteers over two years.
The outcomes of the research, which is being funded by the Nationwide Institute for Well being and Care Analysis, the analysis funding arm of the NHS, are anticipated in 2026.
Though the precise mechanism shouldn’t be but clearly understood, cold-water remedy does appear to set off a rise in white blood cells, a part of the immune system, explains Professor Mercer, who has studied temperature regulation within the human physique for 50 years.

Dr Fadi Jouhra, a marketing consultant heart specialist at St George’s College Hospital and the Harley Road Clinic in London, says the very fact cold-water immersion stimulates manufacturing of immune cells – notably interleukin-6, B and T cells – may assist with auto-inflammatory circumstances, equivalent to Behcet’s, by decreasing irritation.
Though he stresses there are at present no trials to help this, and he cannot but advocate it primarily based on the science, he provides: ‘Behcet’s is a really troublesome situation to deal with, so if you will get reduction on this means, it could be price a attempt if you haven’t any coronary heart circumstances.’ (It’s because the guts could battle to deal with the sudden improve in blood strain and coronary heart fee attributable to cold-water immersion.)
Rosie began having chilly showers final yr after Holby Metropolis ended. She was so happy with the outcomes, she purchased an ice bathtub. ‘I would say ice baths improved my Behcet’s signs by 95 per cent,’ she says.
‘Possibly it is partly the placebo impact, however I am so significantly better. Now if I get any lumps on my arms or legs, they’re smaller and go away round 75 per cent faster than they did earlier than.
‘I am additionally considerably more healthy – I get the occasional chilly, but it surely by no means lasts lengthy.’
However specialists agree it is too early to advocate cold-water remedy, and there are potential dangers.
Dr Heather Massey, a senior lecturer in sport well being and train science at Portsmouth College, says that though some folks could expertise well being advantages from cold-water immersion, ‘the extent of proof is not ample to advocate it’.
The downsides embrace ‘very painful, chilly, numb and swollen palms and toes’, and worse – ‘folks have had cardiac arrests going into chilly water in addition to strokes. Normally these involved had an underlying coronary heart or different medical situation, and whereas some could pay attention to their situation, others could not’.
Dr Massey advises checking your well being standing with a physician earlier than attempting an ice bathtub.
Having one other individual available whenever you experiment with cold-water immersion could also be a good suggestion if you happen to really feel uncertain, ‘in order that if you happen to get into issue, there are folks available to help you’.
