The human body in the nap after the shock, emotional excitement or stress, may cause a transient increase in blood pressure, which is a normal physiological phenomenon, most patients will be emotionally stable after the blood pressure returned to normal. If the patient’s blood pressure is measured 3 times on a non-same day after a nap, and the diastolic blood pressure exceeds 90mmHg, and/or the systolic blood pressure exceeds 140mmHg, it is mostly considered to be caused by high blood pressure.
