Immunity is not built at the pharmacy
Every autumn, the same ritual repeats: vitamin C, zinc, echinacea, garlic. Does it help? Partly. But truly strengthening the immune system requires more than supplements — it requires a systemic regeneration of the body.
And that is exactly what the spa offers. Not a single miracle remedy, but a comprehensive environment that trains, strengthens, and calibrates the immune system.
How the immune system works (simplified)
The immune system has two main branches:
- Innate immunity — the first line of defence: skin, mucous membranes, NK cells (natural killers), phagocytes
- Adaptive immunity — specific defence: T-lymphocytes, B-lymphocytes, antibodies
Both branches need the following to function properly: sufficient sleep, low chronic stress, physical activity, clean air, and mineral nutrition. Everything the spa naturally provides.
Mineral springs and immunity
The mineral springs of Marienbad contain a spectrum of minerals and trace elements that the immune system needs:
Iron (Forest Spring, Ambrose Spring)
Iron is essential for T-lymphocyte proliferation. Iron deficiency — even subclinical — weakens the immune response. A drinking cure with iron-rich springs replenishes reserves naturally, with better bioavailability than tablets.
Magnesium (Maria Spring)
Magnesium regulates inflammatory processes. When it is deficient, levels of pro-inflammatory cytokines rise — the body enters a state of permanent low-grade inflammation that exhausts the immune system.
Bicarbonates (Cross Spring, Rudolf Spring)
Alkaline springs support the balance of the internal environment. Proper pH is crucial for the function of immune system enzymes.
Forest air: a natural immunostimulant
The Slavkov Forest surrounding Marienbad is a source of phytoncides — volatile organic compounds that trees release as a defence against pathogens. When you breathe them in, your immune system responds:
- An increase in NK cells (natural killer cells) of 40–50% after 3 days in the forest
- Elevated levels of perforin and granzymes — proteins that NK cells use to destroy infected cells
- The effect persists for 7–30 days after leaving the forest
These data come from extensive Japanese studies by Professor Qing Li of Nippon Medical School, who introduced the term shinrin-yoku (forest bathing) into medical practice.
CO₂ baths and immunity
Carbonated baths do not have a direct immunostimulatory effect, but their influence on immunity is indirect and highly significant:
- They improve circulation — immune cells reach their destination faster
- They lower blood pressure — less strain on the cardiovascular system = more resources for immunity
- They promote regeneration — the body repairs damaged cells more effectively at rest
Stress: immunity's greatest enemy
Chronic stress is demonstrably immunosuppressive. Cortisol — the stress hormone — suppresses antibody production, reduces lymphocyte counts, and slows wound healing.
A spa stay is one of the most effective ways to reduce chronic stress:
- No work obligations
- Regular daily rhythm
- Exercise in nature
- Quality nutrition
- Relaxed social interaction
When should you visit to boost immunity?
| Period | Why? |
|---|---|
| September–October | Preparation for the winter season |
| January–February | Recovery from holiday stress |
| March–April | Spring fatigue, convalescence after flu |
| After illness | Rebuilding immune reserves after infection |
| Year-round | Chronic stress, frequent illness, fatigue |
Recommended programme for strengthening immunity
- Drinking cure — 3 times daily, spring as recommended by a doctor
- Terrain therapy — 45–90 minutes daily in the forest
- Carbonated bath — every other day, 20 minutes
- Sauna — twice a week (cold exposure trains the immune system)
- Sleep — 8 hours in a quiet environment without light pollution
Ideal length of stay for measurable immune strengthening: 10–14 days.
