Spa treatment for the respiratory tract — an autumn cure guide to Mariánské Lázně

When breathing becomes a treatment

Most guests come to Mariánské Lázně for their backs, their joints or their metabolism. Yet the respiratory tract has been part of the town's healing repertoire from the beginning — it forms an officially recognised indication group of its own. Spa treatment for the respiratory tract here rests on a combination that is hard to assemble anywhere else: a mineral water suited to inhalation, naturally occurring carbon dioxide, peat, and a climate that counts as a healing resource in its own right.

Autumn may be the best time of year for this particular cure. The pollen season is winding down, the town quietens after the summer, and the air in this forest-ringed valley has the damp freshness that mucous membranes dried out by air conditioning and the start of the heating season are crying out for. If you are weighing up an autumn stay, this is its healthiest version.

A climate with a certificate

Mariánské Lázně sits at roughly 630 metres above sea level, in a basin enclosed by the woods of the Slavkovský les protected landscape area. The submontane climate here is described as tonic: it gently stimulates and hardens the body without exhausting it. For the airways, what matters most is what the valley lacks — dust, smog and the hot, dry summer air of the lowlands.

Since 2023 this has been official. The town was granted the status of a climatic spa, the sixth in the Czech Republic and the second in the Karlovy Vary region. It followed air-quality measurements by the Czech Hydrometeorological Institute, which ran at regular intervals throughout the year from May 2021; according to the town, the recorded values fell well below the limits set by Czech legislation. It is the combination of mineral waters, peat, natural spring gas and certified air that makes climate therapy here rather more than a walk in the woods.

The Forest Spring, and why it is the one you inhale

Of the town's forty-plus springs, one holds a special place where breathing is concerned: the Forest Spring (Lesní pramen). Its water is heavily saturated with carbon dioxide and rich in bicarbonate and sodium — the components balneology has long associated with loosening mucus and helping mucous membranes recover. According to the analysis published by the town's official tourism portal, the water contains 2,960 mg/l of carbon dioxide, 1,352 mg/l of bicarbonate and 549 mg/l of sodium, with total mineralisation of around 2,752 mg/l.

The spring is used for drinking cures, for gargling and — the point here — for inhalation, chiefly in disorders of the upper respiratory tract and the digestive system. Its neoclassical pavilion stands away from the main promenade, by the Třebízský brook in the wooded part of the spa district; the walk out to it is a small terrain cure in itself. One caveat about the pavilion: according to the town portal it is currently temporarily closed, while the original outflow of the spring stays freely accessible. Check the current position before you set off.

Forest Spring water is also piped directly into several spa houses — among them the Nové Lázně and Pacifik hotels of the Ensana group — so inhalations and drinking cures do not end when the pavilion closes. The full profile of the spring, and where to find it, is in the Forest Spring entry.

What a cure actually consists of

A respiratory cure is not a single treatment but a composed daily routine. What goes into it is decided by the spa physician at the entry examination, on the basis of diagnosis, age and any accompanying conditions — so what follows is a map of the possibilities, not a prescription.

• Mineral water inhalation. The foundation. Finely atomised Forest Spring water moistens the mucous membranes and is traditionally used to loosen secretions; a systematic review of 27 studies reports better nasal patency and mucociliary transport after mineral water inhalation, while pointing to the low quality of the studies (Fontana et al., 2025, Int J Biometeorol). Two sessions a day are typical.
• Breathing rehabilitation. Individual and group physiotherapy focused on breathing patterns: prolonged exhalation, diaphragmatic breathing, coughing technique. This is the part of the cure you take home permanently.
• Carbon dioxide baths and dry gas applications. Carbon dioxide absorbed through the skin dilates the small vessels and increases blood flow in the skin (Pagourelias et al., 2011, Int J Biometeorol); in Mariánské Lázně it comes from a local source. For respiratory diagnoses it is a supplementary treatment, and the physician decides whether to include it.
• Drinking cure. Supplementary, according to diagnosis. One rule admits no exceptions: which spring, how much and when is always set individually by a doctor. Our drinking cure guide explains how that works in practice.
• Climate therapy and terrain cure. Guided walks at a defined pace and gradient — precisely what the historic network of promenade paths was built for. In COPD, supervised walking is a well-documented form of training: in a multicentre randomised trial of 143 patients it improved quality of life and endurance walking after 8–10 weeks (Wootton et al., 2014, Eur Respir J) — though that was an outpatient programme, not a spa stay.
• Supporting treatments. Depending on your condition, these may include massage, a salt cave (there is one at the Hvězda hotel) or relaxation techniques that help with breathlessness and tension.

Who the treatment is for

Czech spa medicine works from an indication list forming part of Decree No. 2/2015 Coll. on the professional criteria for spa rehabilitation care (most recently amended by Decree No. 586/2025 Coll.). Respiratory disorders make up indication group V.

For adults, the Mariánské Lázně medical spa company lists in particular:

• chronic inflammations of the airways
• bronchial asthma
• allergic rhinitis
• conditions following surgery of the lower respiratory tract
• COPD and states after pneumonia, including the after-effects of COVID-19

Exactly which diagnoses qualify, the admission conditions, the length of stay and whether a cure can be repeated are all governed by the current wording of the indication list, and the referral is issued by the treating physician. The indication list groups these diagnoses as follows:

Non-tuberculous diseases of the respiratory system

Diagnoses in this indication group

• Conditions after surgery of the upper and lower respiratory tract, not concerning conditions after surgery of tonsils, adenoid vegetations and the nasal septum

• Conditions after lung transplantation

• Damage of the larynx and vocal cords due to vocal overload

• Conditions after phonosurgery treatment

• Conditions after complicated pneumonia

• Bronchiectasis

• Recurring inflammations of the lower respiratory tract and chronic inflammations of the respiratory system as an occupational illness according to separate legal enactments

• Asthma bronchiale

• Chronic obstructive pulmonary disease

• Interstitial lung fibrosis of any aetiology under systematic care

• Consequences of toxic gases, smoke, corrosive vapours and irritant dusts to the upper and lower respiratory tract

Whether a stay is appropriate is for your doctor to judge; most international guests arrange the stay privately. Full list of indications and contraindications

That route applies to patients within the Czech public system; international guests usually come as self-payers, receiving the same treatments without the referral procedure and able to book shorter preventive or convalescent stays. If your aim after a serious respiratory illness is chiefly to rebuild strength, see our article on post-COVID rehabilitation.

There are contraindications too — acute infectious illness, active malignancy, pregnancy or an inability to manage daily self-care. That assessment belongs with a doctor, not a search engine.

Why autumn in particular

An autumn date has concrete advantages for the airways.

The pollen recedes. The grass season ends in summer, but mugwort and ragweed flower into October. It is October when airborne pollen drops away markedly — so a patient with an allergic component can take the cure at a moment when their mucous membranes are not fighting an allergen at the same time. If mugwort affects you, discuss the timing with your doctor; for some, the second half of October is ideal.

The heating season begins. Dry air in overheated flats and offices is one of the year's least forgiving combinations for the upper airways. Two or three weeks in cool, moist air, inhaling twice a day, is good preparation for winter.

The town settles. After August the festival crowds leave and the spa returns to the pace people come here for: no queues at the springs, room on the promenade, treatments easier to schedule.

The forest is at its best. Damp, cool, resinous air after autumn rain is ideal for breathing exercises outdoors — and the beech and maple stands above the colonnade turn an ordinary terrain cure into something worth looking at.

Length of stay, and what to expect

For stays covered by Czech public health insurance, the length is set by the indication list according to the diagnosis: for asthma and COPD (V/5) it is 28 days of comprehensive care or 21 days of contributory care, and for states after complicated pneumonia (V/3) 21 days. Self-paying guests most often choose two to three weeks, agreed with the spa physician; anything shorter works as prevention or convalescence rather than treatment. The effect of the inhalations and breathing exercises accumulates — the first subjective relief, easier expectoration, a clearer nose or calmer breathing at night, does not as a rule arrive on the very first day but over the course of the first week, once the body has settled into the rhythm.

What to expect from the cure as a whole is suggested by a German study: a three-week programme of outdoor breathing exercises twice a day under medical supervision, at an altitude of around 700 metres, improved the mean FEV1 of 678 patients with asthma and COPD from 71 to 78 % of the predicted value (Müller et al., 2018, Eur J Integr Med). The study had no control group, so the effect of the climate cannot be separated from that of the exercise and supervision — but it shows what such a regime can achieve.

Keep expectations realistic. A cure does not replace prescribed medication, and it will not cure a chronic condition. Its aims are to calm the mucous membranes, open the airways, train a workable breathing technique, and send you home in better condition; any adjustment to your medication is a decision for your own treating physician. With chronic diagnoses the benefit is counted in months, which is why the cure is repeated for many indications.

An autumn diary: what is on in town

Treatments take up the morning; the afternoon is yours. The autumn programme is busier than you might expect:

• 17–20 September 2026 — the Marienbad Autumn international folklore festival, with ensembles from Italy, Poland and Slovakia; opening at the Chopin House, gala concert at the Municipal Theatre.
• 7–20 September 2026 — European Heritage Days, this year on the theme of endangered monuments, opening buildings that are closed for the rest of the year.
• September — the traditional mushroom exhibition drawn from the spa forests, and a food festival on the colonnade.
• October — the spa apple festival in the town centre.
• until 31 October — the Singing Fountain plays on every odd hour from 7 a.m., with illuminated evening performances at 9 and 10 p.m. Then it falls silent until spring.

Colonnade concerts by the West Bohemian Symphony Orchestra run right through the season — the pleasantest way to spend an hour outdoors without walking a single kilometre.

Before you pack

Bring layers: mornings in the valley are misty and cold, afternoons can be fifteen degrees and sunny. Add a waterproof jacket and shoes that cope with forest paths after rain, and a flask, because drinking after inhalations is part of the routine. Above all, bring recent reports from your GP or specialist — without them the spa physician cannot build a treatment plan that genuinely matches your condition.

Mariánské Lázně in autumn offers something no other season provides: quiet, clean air and time. For the respiratory tract, that is a combination no pharmacy stocks.
