Occasional high blood pressure can be temporarily observed if it is not particularly high, and if it is persistently elevated it is recommended to follow medical advice. According to the diagnostic criteria of hypertension, if the systolic blood pressure is ≥140mmHg and/or the diastolic blood pressure is ≥90mmHg three times on a non-same day, it will be diagnosed as hypertension. A normal person’s blood pressure fluctuates throughout the day, is not static and will fluctuate within a reasonable range. Blood pressure is influenced by diet, exercise, and emotions. Therefore, if a normal person’s blood pressure is normal, and once in a while high blood pressure occurs, it can be temporarily observed, and if it is not particularly high, there is no need to take antihypertensive drugs. If the persistent elevation is recommended to consult a doctor in a timely manner, you can use medication under the guidance of the doctor. High blood pressure after strenuous exercise can return to normal after enough rest. Emotional fluctuations, such as nervousness, anxiety, excessive joy or sadness can also lead to a temporary increase in blood pressure, which will return to normal after emotional adjustment. Antihypertensive medication should only be taken after a diagnosis of high blood pressure has been made and prescribed by a doctor, as self-medication is likely to cause side effects.
