A recent study has revealed a significant link between rising temperatures and cardiovascular disease, warning that heart-related health issues could double or even triple in the next 25 years if climate trends persist.
Published in the European Heart Journal, the study analysed data from the Australian Burden of Disease Database spanning from 2003 to 2018. Researchers found that extreme heat was responsible for the loss of 49,483 years of healthy life annually due to heart disease. The findings suggest that the impact of extreme weather conditions is likely to increase dramatically in the coming decades.
How hot weather affects the heart
Professor Peng Bi from the University of Adelaide explained in the report that the human heart must work harder in hot weather to regulate body temperature, placing additional strain on the cardiovascular system. This can be particularly dangerous for individuals with pre-existing heart conditions.
The study estimated that 7.3 percent of the total burden of cardiovascular disease and related deaths could be linked to extreme weather conditions. Projections based on climate models indicate that this number could double or even triple by 2050, depending on greenhouse gas emission levels outlined by the Intergovernmental Panel on Climate Change (IPCC).

A groundbreaking global study
Lead researcher Jingwen Liu, also from the University of Adelaide, emphasized the global relevance of the study. While the research focused on Australia, similar associations between high temperatures and cardiovascular risk have been observed worldwide.
“Our study is the first of its kind globally, providing a comprehensive analysis that can help shape future climate adaptation and mitigation strategies,” Liu stated.
Solutions to reduce the health impact of heat
The study also highlighted the potential for reducing the health risks of extreme heat through adaptive strategies. Researchers stressed the importance of proactive measures, including:
- Urban cooling initiatives, such as increased green spaces and reflective surfaces.
- Public health campaigns to raise awareness about heat-related cardiovascular risks.
- Improved emergency response plans for extreme weather events.
Professor Bi urged governments and health authorities to invest in adaptation and mitigation strategies to protect vulnerable populations from the growing threat of climate-related heart disease.
