Up to one fifth of the population suffers from allergies to be treated by medications. However, medical drugs need not be the only solution, because speleotherapy appears a very good alternative – the method using the properties of the caves, in particular the underground aerosol. The cave environment is virtually not replaceable in an artificial way, since it is dust-free, allergen-free, and its relative humidity approaches 100 per cent. The Jasovská jaskyňa cave currently serves as one of three caves in the country for the treatment of respiratory tract diseases.

In addition, it is also a true witness of the history – the story has it that the cave was discovered by one of the monks of the Premonstratesian Order based in Jasov, with the first written mention of its existence dating back to 12th century. The cave is associated with a number of archaeological finds, from which it is clear that it was inhabited in the Neolithic period; some of the findings even point to a possible short-term settlements in the Paleolithic period. We may find inscriptions and drawings on the cave walls; for example, there is an extremely valuable inscription of the year 1452, which records the victory of the troops of Ján Jiskra of Brandýs at the battle of Lučenec, and it is the oldest documented inscription in the Slovak caves. In the Dome of Bats we may find the date of 1576.

One of the three Slovak caves used for the treatment of airways by inhalation of the cave aerosol.

Several parts of the cave are adorned by a rich sinter filling, sinter "waterfalls" or drums would also attract attention. Experts discovered up to 19 species of bats in the cave that assemble there especially in the winter. The Jasovská jaskyňa cave is one of the most important wintering areas of the Greater Horseshoe Bat in Slovakia. The length of accessible section of the cave is 550 metres, the tour would take about 45 minutes. Visitors would for sure feel it in their legs, since they are to climb 314 stair steps. The temperature of the cave varies between 8.8° C and 9.4° C, with the relative humidity ranging between 90 percent and 98 percent.
