Summary
The observed global climate change is an indisputable cause of the increased frequency of extreme weather events and related natural disasters. This phenomenon is observed all over the world including Poland. Moreover, Polish citizens as tourists are also exposed to climate phenomena that do not occur in our climate zone. Extreme weather events and related disasters can have a significant impact on people with allergic diseases, including asthma. These effects may be associated with the exposure to air pollution, allergens, and specific microclimate conditions. Under the auspices of the Polish Society of Allergology, experts in the field of environmental allergy prepared a statement on climate changes, natural disasters and allergy and asthma to reduce the risk of adverse health events provoked by climate and weather factors. The guidelines contain the description of the factors related to climate changes and natural disasters affecting the course of allergic diseases, the specific microclimate conditions and the recommendations of the Polish Society of Allergology for vulnerable population, patients suffering from asthma and allergy diseases, allergologists and authorities in the event of climate and weather hazards.

Relevance
The formulation and dissemination of prevention recommendations based on the state of the art at the state level, taking into account local populations particularly exposed to health risks, is highly advisable. Allergologists should know which populations are most vulnerable to the harmful health effects of inhalation exposure to particulate matter (children, the elderly, people with chronic respiratory diseases - asthma, emphysema, bronchitis and chronic cardiovascular diseases).
People living close to sources of dust emissions, in the event of higher levels of emissions, should stay indoors and avoid inhaling fumes and dust.
Asthmatic patients should be informed of the potential negative effects of exposure to very cold air, which may require modification of doses of anti-asthma medication. These patients should avoid exposure to extremely cold temperatures that shorten the duration of outdoor activity, particularly intense exercise.
