Blood pressure is highest in winter, when the cold weather causes the body’s blood vessels to constrict, resulting in a relative increase in blood pressure. If you do not have hypertension, it is fine to have slightly higher blood pressure in winter. If you are a hypertensive patient, you need to pay more attention to measuring blood pressure, treating changes according to your body, and adjusting blood pressure medication appropriately to stabilize your blood pressure. Pay attention to keeping warm in winter, minimize outdoor exercise, and don’t get too emotional to avoid raising blood pressure. Patients with hypertension will have high weight, so try to control their weight, appropriate fat loss is extremely helpful in lowering blood pressure, and eating more vegetables and fruits and less greasy food can stabilize blood pressure.
