Cold weather and a sudden drop in temperature can cause a heart attack, according to new research. Doctors say that every temperature difference of five degrees Celsius on any given day increases the risk of a heart attack by about five percent.
Although it is not entirely clear why this happens, Professor Hedwig Anderson from the University of Michigan says that, although the body has efficient systems of reaction to temperature changes, accelerated and extreme fluctuations cause stress to all systems, which contributes to the appearance of health problems, writes the Daily Mail.
Doctors warn that in cold weather the blood thickens, which causes an increase in pressure.
The research results state that temperature differences of more than 25 degrees Celsius carry the greatest risk of a heart attack, while changes of 10 to 25 degrees on a smaller scale are dangerous for the heart.
The effects are greater if extreme temperature fluctuations occur when the days are already warm, reports B92.
