It has been shown that when heating energy prices rise, the number of people suffering from cardiovascular disease (CVD) increases. This suggests that trying to save on heating costs is highly likely to lead to stroke or myocardial infarction.
The latest issue of the international academic journal ‘Environmental Research’ published a study on ‘Changes in the association between cold and cardiovascular disease due to changes in natural gas prices.’
Professor Hyeong-Jin Yoon of the Department of Human Systems medicine at seoul National University College of Medicine, Professor Gyeong-Nam Kim of the Department of Preventive Medicine at Yonsei University College of Medicine, Soo-Hwan Kim of the Department of Information and Statistics at Gyeongsang National University, and Yu-Jin park, a data scientist at Kangbuk Samsung Hospital, jointly participated in the study.
The researchers analyzed data on 5,958,617 cases of cardiovascular disease hospitalization and death that occurred in 16 cities and provinces across the contry from January 2012 to February 2017.
In particular,we focused on the correlation between changes in the price of natural gas,the country’s main heating energy,and the occurrence of cardiovascular disease.
As an inevitable result, during the period when natural gas prices were increasing (January 2012 to December 2014), cardiovascular disease hospitalizations were 1.71 times higher than during the period when natural gas prices were decreasing (January 2015 to February 2017). .
The research team analyzed that this may be because households reduced their heating use during times of rising energy prices.
Cardiovascular disease is greatly affected by temperature. Blood vessels react sensitively when the temperature suddenly drops or when the daily temperature difference is large. Every time the temperature drops by 1 degree, systolic blood pressure increases by 1.3 mmHg and diastolic blood pressure increases by 0.6 mmHg, putting a strain on the heart.
Therefore, diseases such as stroke and myocardial infarction occur frequently in winter. in particular, the risk increases if you are elderly or have underlying diseases such as high blood pressure, diabetes, or dyslipidemia.
Although the link between low ambient temperatures and cardiovascular disease is well known, the impact of winter energy prices has been less well known.
“Our findings suggest that cold weather increases the risk of cardiovascular disease, which can be alleviated with adequate heating,” the research team said. “Policies on energy prices should take into account the impact on the public.”
