Researchers warn of rising heart disease risk due to hot weather in coming decades

A study published in the European Heart Journal on Monday has revealed a concerning connection between hot weather and cardiovascular disease in Australia, highlighting the significant health toll of extreme temperatures. Researchers found that nearly 50,000 years of healthy life are lost annually due to heart disease linked to hot weather. The report warns that if current climate trends continue, the impact of weather-related cardiovascular issues could double or even triple within the next 25 years. The study, which used data from the Australian Burden of Disease Database covering the period from 2003 to 2018, found that 7.3% of the total burden of cardiovascular disease could be attributed to extreme heat. Lead author Jingwen Liu from the University of Adelaide stated that this is the "first study of its kind globally" and highlighted the relevance of these findings for planning future climate change adaptation strategies. Professor Peng Bi, a co-author of the study, explained the physiological strain caused by high temperatures: “When the weather is hot, our hearts must work harder to help us cool down. This added pressure can be dangerous, especially for people with cardiovascular disease.” The researchers stress the importance of urgent investment in urban cooling solutions, public health campaigns, and improved emergency responses to mitigate the health risks of extreme heat.
