A groundbreaking study on temperature and public health in Cabo Verde has found that nighttime heatwaves are the most significant threat to public health in the archipelago. According to Giseila Garcia, an epidemiologist at the National Institute of Public Health (INSP), the study shows that heatwaves in Cabo Verde occur more frequently at night, contrary to the public's perception that daytime exposure to the sun is the greatest risk.
The study, conducted in partnership with the National Institute of Meteorology and Geophysics (INMG) and funded by Luxembourgish Cooperation, analyzed six municipalities in Cabo Verde: São Vicente, Sal, Praia, Ribeira Brava, Fogo, and Brava. The research, prepared in 2024 and implemented in January 2025, highlights the impact of excessive heat on the health of the population, particularly in respiratory diseases, and exacerbating dermatological and chronic conditions.
The study's findings have enabled Cabo Verde to define its own specific parameters for determining and classifying heatwaves in the country. This development is crucial in mitigating the effects of climate change on health. According to Garcia, the heat excess affects the health of the population transversely, with a primary impact on respiratory diseases, and also aggravates dermatological and chronic pathologies.
To address the risks associated with heatwaves, authorities are designing an early warning system based on two fronts: installing thermal sensors on the island of Brava and officially publishing the data. The system aims to provide continuous collection of meteorological and health data in the long term. The publication of official data on heatwaves defined for the country in the Official Bulletin is the next step.
The research has significant implications for public health policy in Cabo Verde. By understanding the country's specific heatwave patterns, authorities can develop targeted interventions to reduce the risks associated with heat-related illnesses. The study's findings also underscore the need for increased awareness and education on the risks of nighttime heatwaves.
The partnership between INSP and INMG has been instrumental in advancing the understanding of the relationship between temperature and public health in Cabo Verde. The study's results are expected to inform policy decisions and guide the development of effective strategies to mitigate the impacts of climate change on health.
The implementation of the early warning system and the publication of heatwave data are critical steps towards reducing the health risks associated with nighttime heatwaves in Cabo Verde. The study's findings and recommendations are expected to contribute to improved public health outcomes and enhanced resilience to climate-related hazards in the archipelago.
Key points
- Nighttime heatwaves pose a greater threat to public health in Cabo Verde than daytime heat exposure.
- The study analyzed six municipalities in Cabo Verde and defined specific parameters for determining and classifying heatwaves in the country.
- Authorities are designing an early warning system, including thermal sensors and official publication of data, to mitigate the effects of heatwaves on health.
