Rising temperatures in the Netherlands pose growing health risks
The Dutch public health system is experiencing significant effects from climate change, with rising temperatures, increased UV radiation, and the spread of infectious diseases already taking a measurable toll, according to a report published Monday by the National Institute for Public Health and the Environment (RIVM).
"Climate change is already worsening health outcomes in the Netherlands," the report states. "This is evident across multiple health areas, including mortality, respiratory illnesses, infectious diseases, and mental health."
The report examines the health impacts of climate change between 1991 and 2020. It identifies extreme heat, worsening air quality, prolonged allergy seasons, and the increased spread of diseases as key risks for Dutch residents. The findings, based on 30 years of data, indicate that these trends are likely to intensify in the coming years.
The strongest evidence of climate change’s health impact comes from an increase in heat-related deaths. The RIVM report found that higher average temperatures and longer, hotter heatwaves now contribute to an average of 250 additional deaths per year in the Netherlands. Warm days with temperatures above 20 degrees and prolonged heatwaves have become more frequent, exacerbating health risks, particularly for vulnerable populations.
Climate change has worsened air quality and allergy-related health problems, according to the report. Hot and dry weather conditions are often accompanied by elevated levels of pollen and ozone, also known as summer smog, which can cause respiratory issues, particularly among individuals with pre-existing conditions such as asthma or chronic obstructive pulmonary disease (COPD).
The growing season for plants is also lasting longer, resulting in higher concentrations of pollen in the air over extended periods. This has led to an increase in hay fever cases, with more people developing allergic symptoms or experiencing more severe reactions.
The report also highlights a concerning rise in UV radiation exposure, attributed to longer hours of sunshine, fewer clouds, and an increase in outdoor activities during warmer weather. Prolonged UV exposure significantly raises the risk of skin cancer. The RIVM noted that preventive measures such as sun protection and public awareness campaigns are crucial to mitigate these risks.
Infections
Certain infectious diseases are also becoming more prevalent due to climate change, the RIVM found. Legionnaires' disease, caused by the Legionella bacteria, is one such example. The bacteria thrive in warm water and can be inhaled through mist, such as during heavy rainfall following warm and dry periods.
Ticks, which carry Lyme disease, are now active for longer periods throughout the year as winters become milder. This extended period of tick activity increases the risk of tick-borne illnesses.
The report also cites mental health as an emerging area of concern linked to climate change. The increasing threat of extreme weather events and the stress of dealing with these changes can negatively impact mental well-being. Individuals affected by severe weather or who experience prolonged uncertainty may develop anxiety, depression, or other mental health conditions.
Nonetheless, the RIVM emphasized the need for further research to better understand the long-term health consequences of climate change and to develop effective policy measures.
