What is Normal Blood Pressure by Age?

Blood pressure refers to the force at which blood pushes against the walls of your arteries. Maintaining healthy blood pressure is essential, as abnormal blood pressure levels can lead to various health issues such as stroke, heart attack, and kidney failure.

This article will explore the normal blood pressure ranges by age, discuss different blood pressure categories, and provide tips to maintain optimal blood pressure levels.

Blood Pressure Categories and Their Numerical Values

In general, blood pressure is expressed in millimeters of mercury (mm Hg) and is primarily recorded as two numbers: systolic (top number) and diastolic (bottom number).

In simpler terms, systolic pressure represents the force of blood in the arteries when the heart beats. Diastolic pressure measures the force when the heart is at rest between beats.

According to the recommendation of the American Heart Association, blood pressure can be classified into the following categories:

NormalLess than 120Less than 80
Elevated120–129Less than 80
High Blood Pressure (Stage 1)130–13980–89
High Blood Pressure (Stage 2)140 or higher90 or higher
Hypertensive CrisisHigher than 180Higher than 120

Blood Pressure Ranges by Age

Generally, blood pressure levels can vary depending on a person’s age, as the elasticity of blood vessels changes over time.

The following chart, as provided by The University of Iowa Stead Family Children’s Hospital and Baptist Health, illustrates the average normal blood pressure ranges by age:

Age GroupSystolic RangeDiastolic Range
Newborns (up to 1 month)60–90 mm Hg20–60 mm Hg
Infants87–105 mm Hg53–66 mm Hg
Toddlers95–105 mm Hg53–66 mm Hg
Preschoolers95–110 mm Hg56–70 mm Hg
School-aged children97–112 mm Hg57–71 mm Hg
Adolescents112–128 mm Hg66–80 mm Hg

Adult Blood Pressure Averages by Age and Gender

Age & GenderAverage Blood Pressure
Women (18-39)110/68 mm Hg
Men (18-39)119/70 mm Hg
Women (40-59)122/74 mm Hg
Men (40-59)124/77 mm Hg
Women (60+)139/68 mm Hg
Men (60+)133/69 mm Hg

Please note that these are average values, and individual blood pressure levels may vary. Consult a healthcare professional for personalized advice.

Precautions and Preventative Measures

To maintain healthy blood pressure levels, you should:

  1. Monitor regularly: Regularly check your blood pressure to detect any changes.
  2. Exercise: Engage in physical activity to strengthen your heart.
  3. Eat well: Consume a balanced diet rich in fruits, vegetables, and whole grains.
  4. Limit salt: Reduce your sodium intake to avoid raising blood pressure.
  5. Manage stress: Practice relaxation techniques to keep stress levels under control.

Frequently Asked Questions about Blood Pressure

What is the difference between systolic and diastolic blood pressure?

Systolic blood pressure refers to the highest pressure when your heart is beating and pumping blood, while diastolic blood pressure is the lowest pressure when your heart is at rest between beats. Both values are essential in determining your overall blood pressure health.

How often should I check my blood pressure?

You should consult your healthcare provider for personalized recommendations on how often to check your blood pressure. Generally, if you have normal blood pressure, you might be advised to check it once every two years. However, if you have high blood pressure or other health concerns, you may need to monitor it more frequently.

Can I have symptoms of high or low blood pressure?

High blood pressure (hypertension) often has no visible symptoms, which is why it’s known as a “silent killer.” On the other hand, low blood pressure (hypotension) can cause symptoms like dizziness, fainting, and fatigue. If you experience these symptoms, consult your healthcare provider for further evaluation.

How can I lower my high blood pressure?

To lower high blood pressure, you can make lifestyle changes, such as exercising regularly, eating a balanced diet, limiting sodium intake, managing stress, and avoiding tobacco. In some cases, your healthcare provider may prescribe medication to help lower your blood pressure.

Can blood pressure fluctuate throughout the day?

Yes, blood pressure can fluctuate throughout the day due to various factors, including physical activity, stress, and caffeine intake. It’s essential to measure your blood pressure at the same time each day and under similar conditions to ensure accurate readings.
