Effect of Winter on Hypertension

Can Cold Weather or Seasonal Changes in weather impact Blood Pressure?

Blood pressure is usually higher in the winter and lower in the summer, which means that low temperatures restrict your blood vessels, which increases blood pressure because more pressure is required to force blood through your narrowed veins and arteries.


In addition to cold weather, blood pressure may also be impacted by a sudden change in weather patterns, such as a weather front or a storm. A person’s body and blood vessels may react to abrupt changes in humidity, atmospheric pressure, or wind in much the same way it reacts to cold. These weather-related changes in blood pressure are more common in people age 65 and older. Dropping temperatures in winter may cause an unhealthy rise in high blood pressure in elderly people.


In cold weather, a survival mechanism in humans and other mammals restricts blood vessels to maintain heat and body temperature. However, with less room for blood movement, the risk of fatal heart attack and stroke, which peaks in winter, increases.


High Blood Pressure and It’s Effects

High blood pressure is associated with an increased risk of cardiovascular disease and death and is responsible for approximately 8 thousand deaths every year worldwide. Blood pressure shows a seasonal variation in winter months with a tendency to increase. Vitamin D deficiency is more common during months when there is no UVB radiation from the sun and high blood pressure is associated with vitamin D.


Why your blood pressure can spike when it’s cold outdoors?

Blood pressure, which is the force of blood pushing against your artery walls, normally rises and falls throughout the day, according to the Centers for Disease Control and Prevention (CDC).

However, if it remains elevated for a long period of time, it can lead to heart damage, increased risk of stroke and other health issues, the CDC reported.

In 1961, researcher Geoffrey Rose studied seasonal variations in blood pressure and found that cold weather can increase a person’s blood pressure.
