Many factors such as lifestyle, exercise, food and fluids that we take, but also by climate changes affect the results of blood pressure measurements.
Can cold weather and climate changes affect blood pressure?
Generally blood pressure is higher in the winter. That’s because low temperatures narrows the blood vessels that results in necessity of a greater load on the heart to pump the blood through the veins and arteries which causes the increase of the blood pressure.
Sudden weather changes also affect blood pressure. The body – and the blood vessels in it – may react to abrupt changes in humidity, atmospheric pressure, cloud cover or strong wind in much the same way it reacts to cold. Such weather-related variations in blood pressure readings are more common in people aged 65 and older.
Weight gain and decreased physical activity in winter periods are other reasons for increasing of blood pressure related to seasonality. If you have high blood pressure already, continue to monitor your blood pressure readings as the seasons change. Consult with your doctor if there are some difference in readings. He may recommend you to change the dose of your blood pressure medication or replace it with another medication. Don’t make any changes to your medications without talking to your doctor.
