A new research has put light on the fact that the chances of suffering from heart attack in cold weather are more. The study, which has been published online by the British Medical Journal, says that every 1C reduction in temperature is associated with 200 extra heart attacks across the UK.
Cold weather affects people who fall in the age group of 75 to 84 and who have a previous history of heart disease. Less susceptible people are the ones who are taking aspirin. The rise in temperature does not boost the risk of heart attacks, as per the study.
Data for as much as 84,010 hospital admissions for heart attacks in England and Wales were analyzed by the team from the London School of Hygiene and Tropical Medicine. Researcher Krishnan Bhaskaran and colleagues took some factors into account while concluding the results, including air pollution, flu rates, seasonal patterns and long-term trends.
It was found by the researchers that a 1C drop in the average daily temperature led to a collective 2% rise in the risk of heart attacks for 28 days.
Mr. Bhaskaran said, "We found no increased risk of heart attacks during higher temperatures, possibly because the temperature in the UK is rarely very high in global terms”.
