[Climate change and type I allergies at the workplace].

The consequences of climate change, the increasing frequency, duration and intensity of extreme events such as excessive drought, heat waves, large-scale forest fires, heavy rainfall and associated flooding also affect workers' conditions in the workplace in many ways. Allergic diseases of the respiratory tract and skin due to workplace exposure can also arise or be influenced by direct and indirect consequences of climate change. This affects outdoor workers not only through increased exposure to pollen allergens, but also through climate-related increases in typical workplace allergens. As an indirect effect of climate change, manufacturing processes and exposure at workplaces are changing, which can also cause new sensitization and allergies. Lifestyle changes, which are primarily intended to contribute to climate protection and sustainability, can also lead to new or changed products and thus to changed manufacturing processes and exposures in the workplace, so this should also be considered an indirect effect of climate change on the health of workers. The emergence of new occupational sources of sensitization due to new or changed allergen exposures must be considered in the context of occupational health and safety and requires proactive measures to protect workers.
