Introduction
The normal range for human blood pressure is a systolic pressure between 70–140 mmHg and a diastolic pressure between 60–80 mmHg. A blood pressure reading of 140/90 mmHg indicates hypertension. Although there is no definitive diagnostic criterion for hypotension, it is currently considered that blood pressure below 90/60 mmHg can be defined as hypotension.
According to medical definition, blood pressure refers to the force exerted by circulating blood against the walls of blood vessels—this force is known as blood pressure. So, what is the normal blood pressure range for the human body?
Normal Blood Pressure Range for Humans
The normal systolic (high) blood pressure for humans ranges between 70–140 mmHg, and diastolic (low) pressure between 60–80 mmHg is considered within the normal range. A blood pressure reading of 140/90 mmHg or higher indicates hypertension. Although there is no strict diagnostic criterion for hypotension, it is generally accepted that blood pressure below 90/60 mmHg can be classified as hypotension. It is commonly seen in thin, physically inactive young women. Isolated systolic hypertension is diagnosed when systolic pressure exceeds 140 mmHg while diastolic pressure remains below 90 mmHg—for example, a reading of 130/80 mmHg would not qualify, but sustained readings above 140/80 mmHg may indicate this condition.
Blood pressure measurements taken at home may differ from those taken in hospitals or medical facilities. Many people experience elevated blood pressure during clinical visits due to anxiety—a phenomenon known as "white coat hypertension." Therefore, the normal blood pressure value measured at home should typically be slightly lower than the standard reference range.
Human blood pressure fluctuates throughout the day, with nighttime values generally lower than daytime readings. In 24-hour ambulatory blood pressure monitoring, the normal range is slightly lower than the standard clinic-based reference range. We hope this information is helpful. Wishing you good health and happiness!
