Why Does My Blood Pressure Rise in Cold Weather?

high blood pressure in cold weather

Cold weather impacts your heart health in many ways. While the link between cold weather and an increased risk of heart attack has been widely documented, a lesser known risk associated with the cold is a rise in blood pressure. This is something individuals with high blood pressure must be acutely aware of, since it may impact the way you manage your condition.

Studies have demonstrated that a 1.8°F drop in average daily outdoor temperature is associated with a 0.26 mmHG increase in systolic blood pressure. For individuals with heart disease, the increase in blood pressure is even more pronounced.

How Does Cold Weather Impact Blood Pressure?

When the outdoor temperature is very cold, it causes your blood vessels to constrict. This increases the force required to push blood through your narrowed veins and arteries, which elevates your blood pressure.

Other potential reasons why your blood pressure rises in cold weather include:

If your blood pressure is typically in the normal range, this temporary increase due to the cold weather is most likely not a cause for concern. However, if you struggle with high blood pressure, this increase can increase your risk of heart attack and stroke.

A study conducted in France found a 10% increase in high blood pressure readings in winter compared to summer for individuals over the age of 65. Moreover, people over the age of 80 exhibited the highest elevations in blood pressure during winter.

For this reason, it’s critical for seniors to bundle up when going out in extremely cold weather. In addition, it’s important to be on the lookout for warning signs of a potential cardiac incident, such as shortness of breath and chest tightness, when engaging in strenuous physical activity in the cold.
