«Extreme temperatures during hot or cold spells may increase the risk of premature death from heart disease," - according to a new Australian study.The risk of death from cardiovascular diseases is higher during heat than during the cold weather, according to the study, which was published on September 18 in the journal «Circulation: Cardiovascular Quality and Outcomes»."The new data are important in the light of climate change and the growing obesity in humans," - said the lead researcher Kenro Juan School of Public Health and Institute of Health and Biomedical Innovation Technology, the University of Queensland in Brisbane, Australia."With the increasing levels of obesity and related diseases, including diabetes, more people will be vulnerable to extreme temperatures," - says K. Huang in a journal news release."This may lead to an increase in disease future burden of extreme temperatures."

The researchers found that within 72 years by 1 million. People were killed by one person per day due to heart disease.The risk of premature death from heart disease was highest when the heat lasted for two or more days.Previous studies have shown that extreme temperatures can cause changes in blood pressure, blood viscosity, cholesterol and heart rate - according to the press release.Study co-author Adrian Barnett, associate professor of biostatistics at the University said, - "The researchers have a theory about why the death rate during the heat higher than the death rate during the severe cold.""We suspect that people receive protection measures during prolonged cold weather, which may explain why we have not found the risk of cardiovascular death during the cold weather," - said Barnett.
Although the study found an association between ambient temperature and heart disease-related fatalities, it does not establish a causal link.
