In the latest research more than 100,000 patients were analyzed from seven European countries. Research results stated that heart attack risks increases in cold weather than that in hot weather.

Science Daily reported “Researchers observed higher levels of cardiovascular risk factors (Blood pressure, cholesterol and waist circumference) in winter while lower in summer.”

It was also observed that deaths due to cardiovascular diseases were higher in winter and lower in summer.

Levels of Blood pressure, cholesterol, glucose, body mass index and waist circumference were highest during winter (January and February) and lowest in summer (June to August)

The results were presented at the Congress of the European Society of Cardiology. Studies were made in seven different countries.

Research was conducted on 107,090 subjects aged 35-80 years. From which 21,128 subjects were from Belgium, 15,664 from Denmark, 1,626 from France, 18,370 from Italy, 25,532 from Norway, 9,359 from Russia and 15,411 from Switzerland.

In cold weather due to lower environmental temperature, heart has to work harder to maintain body heat. As a result blood pressure rises and so the heart rate increases. Furthermore, blood vessels dilate and blood pressure raises more as there is less room for blood to pass through.

A person suffering from cardiovascular disease, hypertension, or diabetes should take precautionary measures during shoveling snow or winter season.
