Is warm or cold weather good for the heart?

Question

I read that people in northern countries have more heart disease. Does cold weather really influence the cardiovascular system, and, if so, how?

Answer 1

Moderate weather is better. In cold countries due to the change in life style, stress, alcoholism, pork, smoking, etc. are the main causes of CVS diseases.
At the same time cold weather results in vasoconstriction, and during cold spell coronaries are influenced.

Answer 2

Maybe it has nothing to do with the cold.

Perhaps their diet relies more on meat since they can't grow food in the cold weather.

Thus, they have a fattier diet.

The only way I know cold affects blood vessels is by causing the ones nearer the skin to close off so that heat is not lost.

I don't think the weather itself can affect the cardiovascular system, but it can be stressful for a person

Answer 3

Yes cold weather do give little more contraction to all blood vessels and in a way to coronary artery also which supplies the blood to heart !And that way low blood supply will precipitate heart attack over and above they have geniytically small diameter vessels! Not only that they have to take high caloric fatty food for their energy and no much vegetarian is food available they have to depend on animal food which again will rise in their cholesterol and make artery small on deposition of this fatty layer inside it causing again low supply of blood !Always YouRsmE

Answer 4

In colder weather the heart has to work harder. As you breathe your body prewarms the incoming air and to do this it must pump more blood to the head. Many doctors tell their heart patients to move to warmer areas.
