Switzerland has a well-developed health system and, apart from the best-known ones such as cancer and diabetes, has no major diseases to fight. The population does not suffer from obesity or excessive alcohol or tobacco consumption. This leads to an average lifespan of 83 years.
However, a large number of respiratory diseases are affected. The chronic predisposition leads among other things to premature death (about 60 years old) in about 50% of the population.*

Due to asthma (a subcategory of respiratory diseases), which can also be caused by late detection of allergies, I came to hay fever or pollen allergy. About 20%** of the Swiss population suffers from this disorder especially in spring. In general, allergies occur more and more frequently, which is due to the too clean environment and therefore too few resistances in the body, as well as a more aggressive pollen composition from the surrounding areas.
