Regular seasonal changes or sudden climatic variations can lead to hypertension.

Blood pressure is the force exerted by the blood as it circulates through the blood vessels and arteries, as the heart contracts or relaxes.

There are various risk factors for hypertension or high blood pressure, including age, family history, overweight, lack of physical activity, tobacco and alcohol consumption, among others.

But, have you thought about the influence of weather changes on your blood pressure? In these days of intense cold in the mornings and nights, it is advisable to take care of the low temperatures and pay attention to our pressure.

"Generally, the blood pressure it's highest in the winter and lowest in the summer, ”explained Dr. Sheldon G. Sheps, an expert in hypertension and peripheral vascular disease at Mayo Clinic. "This is because low temperatures cause narrowing of blood vessels, which increases blood pressure because more pressure is needed to circulate blood through the veins and arteries that were narrowed," he clarified.

In addition to cold weather, a sudden change in weather patterns, for example a weather front or a storm, can affect blood pressure. "The body and blood vessels can react to abrupt changes in humidity, atmospheric pressure, cloudiness or wind in much the same way that they react to cold." The expert highlighted that these variations in blood pressure that are related to the weather are more frequent in people over 65 years of age, for which he called for redoubled vigilance of grandparents in the face of these phenomena.

Other seasonal causes of increased blood pressure include weight gain and decreased physical activity during winter. People who have already been diagnosed with high blood pressure should keep monitoring the measurements when the seasons change and visit their doctor regularly, who may recommend changing the dose of their medicine or taking a new one.

Remember to always consult your doctor and do not make any changes to your medications on your own. Always ask your questions about how the weather affects your blood pressure.

Keeping your immune system strong requires balance, leading a healthy lifestyle with a balanced diet, the least processed possible and exercising regularly with a regular intake and enough water per day!
