Salt Mine Sanctuary - 18th June 2021

130 metres beneath the ground in a former salt mine in southern Poland, fitness classes are taking place. The caves, both a draw for tourists and a health resort, have been providing salt therapy to patients with pulmonary issues for almost 200 years.

This therapeutic environment is being used to help those suffering the lingering effects of Covid-19, or long Covid. Centre doctor Magdalena Ramatowska talks through the location's benefits.

Magdalena Ramatowska: "Here, above all, the air is pure, without allergens. This environment is excellent for the respiratory tract. There is high humidity, very few draughts and a richness of saline aerosol that acts against inflammation and the spread of bacteria."

Visitors descend into the former mine chamber by lift in small groups. After a thorough assessment, doctors and physiotherapists allocate activities. These vary from dance classes and cardio equipment to breathing games blowing bubbles.

Doctors have identified over 50 distinct physical and psychological ailments present in Covid-19 sufferers. These range from muscle and joint pain, difficulties with balance and coordination to loss of memory and concentration.

The international scientific community remains divided on the benefits of salt therapy. Although many believe it's merely a placebo, physiotherapist Agata Kita notices massive improvements in those that come to the centre.

Agata Kita: Nevertheless, patients who have had Covid can return to a very good state of health. On average, their physical test results improve by 60 to 80 percent."

Recovering Covid patients are referred to the resort by Poland's public healthcare system, which funds three week stays. The centre also welcomes private customers.

Lucyna Szulc, hospitalised and placed on a ventilator for 20 days, feels she is benefiting from her stay.

Lucyna Szulc: "When I came out of the hospital, I had very weak breathing. Now I feel better. I also feel that my physical condition is improving."
