Heatwaves have a significant impact on public health as they can lead to increased mortality. The most vulnerable groups include elderly individuals and patients with chronic conditions such as cardiovascular diseases, respiratory illnesses, mental disorders, diabetes, and obesity. An analysis of the association between heatwaves and increased or decreased mortality (time series from 2020 to 2022) was conducted based on diagnoses (all causes, cardiovascular diseases), gender, and age group (all age groups and those aged 75 and older).

In the period 2002-2023, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics. 

The level of air pollution with ozone has exceeded the target value for protecting human health in recent years at some urban background monitoring stations (Koper, Nova Gorica Grčna) and at the higher-altitude monitoring station Otlica. The long-term health protection goals have been exceeded at all monitoring stations. The warning value has also been exceeded in recent years only in the Primorska region and at higher altitudes, such as Otlica.

In 2022, 75% of energy supply in Slovenia was available to end-users, marking the highest level observed in the period. This percentage is largely influenced by the efficiency of electricity and heat production. In thermoelectric power plants and combined heat and power plants, almost half of the input energy was lost in 2022. Compared to the EU-27 countries, Slovenia ranked in the lower third. Electricity production from combined heat and power plants accounted for just over 6% of total production in Slovenia in 2021, with this share declining in recent years.

Foodborne infections remain a significant public health concern in Slovenia and globally. In 2023, the incidence of these infections in Slovenia decreased by 7% compared to 2022, with viral intestinal infections being the most common. Among bacterial pathogens, Campylobacter, Clostridioides difficile, Salmonella, and pathogenic E. coli are predominant. The World Health Organization estimates that at least one in ten people worldwide contracts a foodborne infection each year, representing a substantial burden on public health.
