There is a relationship between weather and blood pressure levels, but weather is not a determining factor in blood pressure. Blood pressure is a fluctuating process that is influenced by mood, activity, coffee or tea, weather, and medications. Changes in the weather can lead to different levels of temperature, and the resulting constriction of blood vessels can lead to higher blood pressure, while the diastole of blood vessels can lead to lower blood pressure. Weather, however, is not an absolute factor in causing abnormal blood pressure and is often not life-threatening. For patients with high blood pressure measurements, they should be retested several times, maintain a low-salt, low-fat, low-cholesterol diet, and keep up with moderate exercise. If necessary, take antihypertensive drugs (e.g. nifedipine, etc.) as prescribed by the doctor to maintain stable blood pressure. For patients with high blood pressure measured several times, they should consult the hospital in time and standardize the diagnosis and treatment under the doctor’s guidance, so as to avoid delaying the condition.
