What does high blood pressure in the morning mean?

Blood pressure fluctuates naturally throughout the day and tends to increase around the time a person wakes up. However, for many people, blood pressure may be abnormally high in the mornings. Doctors refer to this as morning hypertension. Careful monitoring of blood pressure can alert people to instances of morning hypertension. Healthful lifestyle behaviors and prompt medical treatment may help prevent heart attack, stroke, and other complications of hypertension.
