The Winter Can Trigger A Heart Attack

The Winter Can Trigger A Heart Attack


Cold temperatures cause arteries to tighten, restricting blood flow and reducing the oxygen supply to the heart, all of which can set the stage for a heart attack. "In cold weather, there is more oxygen demand by the heart because it is working harder to do the work and maintain body heat," so your heart rate and blood pressure may increase. The cold can also cause changes to your blood that may increase the risk of developing blood clots, which could lead to a heart attack or stroke. Cold weather can put a lot of stress on the body and affect your heart in a number of ways. Lower temperatures can cause blood vessels to narrow. This means that your heart must work harder to move blood throughout the body. Cold weather can also affect your heart by increasing your blood pressure and heart rate.
