Introduction
Normal blood pressure values are systolic 100–120 mmHg and diastolic 60–80 mmHg. A blood pressure reading of 140/80 mmHg indicates high blood pressure if measured at least twice on separate, non-consecutive days during rest. However, if elevated blood pressure occurs only once or occasionally, it generally does not indicate hypertension; this may be due to mental stress or emotional excitement causing sympathetic nervous system activation, which typically resolves after rest.
Whether a blood pressure of 140/80 mmHg is high generally requires analysis based on specific circumstances. The detailed analysis is as follows:
1. High
Normal blood pressure values are between 100–120 mmHg for systolic pressure and 60–80 mmHg for diastolic pressure. If a blood pressure reading of 140/80 mmHg is obtained from at least two measurements taken on different days under resting conditions, this indicates relatively high blood pressure, as 140/80 mmHg exceeds the normal range.
2. Not high
If the reading of 140/80 mmHg occurs only once or occasionally, it usually does not indicate high blood pressure. It may result from factors such as mental stress, emotional excitement, or adverse visual stimuli causing sympathetic nervous system activation, which typically resolves after a short period of rest.
In daily life, actively maintaining a healthy body weight, avoiding long-term high-salt diets and excessive alcohol consumption, and undergoing regular health check-ups are generally helpful in controlling risk factors and preventing the development of hypertension.
