Blood Pressure Swings and Weather Change
Blood pressure can change with the weather, particularly with temperature. Cold tends to narrow blood vessels, and seasonal changes in activity, food, and daily routines may also matter. A storm forecast cannot tell you what your blood pressure is doing: use a suitable blood pressure monitor and discuss a sustained change with your clinician.
If you notice blood pressure weather patterns, start by making the measurements comparable. Record the readings, measurement conditions, and symptoms before deciding that the weather explains them. Keep taking prescribed medicines unless your care team tells you to change them.
