Overview
Your blood pressure needs regular monitoring because it functions similarly to car tire pressure checks for maintaining safe operations and preventing future breakdowns. The correct blood pressure targets for your age group remain unclear to many people. The following guide explains which blood pressure readings are considered healthy for people at different ages.Why Tracking Blood Pressure Matters
Your blood pressure functions as a fundamental indicator which shows your blood circulation health status. Your doctor together with you will detect potential changes through blood pressure monitoring. Early detection of rising blood pressure enables you to start lifestyle changes before the condition develops into a severe issue. Your doctor uses this method to protect your future health while lowering your chances of experiencing heart attacks and strokes.How Blood Pressure Is Measured
The blood pressure measurement process involves placing a cuff placement around the upper arm followed by inflation and then deflation while taking the reading. The procedure delivers fast results through a painless process.Understanding “mmHg” (Millimetres of Mercury)
- The mmHg measurement in your test results represents "millimetres of mercury." The medical field uses this measurement standard for pressure assessment.
- The blood pressure measurement system used mercury as its pressure indicator during past medical practices.
- The medical term "mmHg" should not concern you because doctors throughout Australia and worldwide use this standard measurement.
Blood Pressure Range & What It Means
The Heart Foundation of Australia provides this table which explains blood pressure readings for adult patients.| Blood Pressure Category | Systolic (Top Number) | Diastolic (Bottom Number) | What It Means |
| Low Blood Pressure | Below 90 | Below 60 | Often harmless if asymptomatic, but can cause dizziness or fainting. |
| Ideal / Normal | Below 120 | Below 80 | The gold standard — maintain these habits. |
| Elevated | 120–129 | Below 80 | Early warning. Lifestyle changes are recommended. |
| High (Hypertension) – Stage 1 | 130–139 | 80–89 | Mild hypertension. Requires monitoring and a management plan. |
| High (Hypertension) – Stage 2 | 140 or higher | 90 or higher | Significant hypertension. Usually needs medication plus lifestyle changes. |
Significance of Blood Pressure Numbers
When measuring blood pressure two numbers are provided: systolic and diastolic pressures. The systolic pressure represents the force exerted on artery walls when the heart contracts and pumps blood. On the other hand, diastolic pressure indicates the force between heartbeats when the heart refills with blood. A normal blood pressure reading is 120/80 mmHg. Therefore 120 signifies pressure during a contraction, while 80 reflects pressure during moments of rest, for your heart. It’s possible to experience health issues in young adulthood. Maintaining a healthy blood pressure level is crucial for reducing the risk of various conditions including:- Heart disease – High blood pressure exerts strain on the heart and causes damage to blood vessels over time. This can result in blockages, blood clots, heart attacks, strokes and other complications.
- Stroke – Uncontrolled hypertension weakens blood vessels in the brain increasing the likelihood of strokes. Managing blood pressure effectively helps lower this risk.
- Kidney problems – The kidneys function as filters in our bodies. High blood pressure can gradually harm these organs, potentially leading to impaired kidney function or even kidney failure.
- Vision loss – High blood pressure affects the blood vessels in the retina causing damage that can result in vision problems or even blindness.
- Cognitive problems – Research suggests that high blood pressure during midlife may be associated with dementia and cognitive decline in life.
Calculate Your Blood Pressure
The machine performs all blood pressure calculations without requiring your manual intervention. The main requirement for accurate results involves obtaining proper measurements.- Sit Down: Rest quietly for 5 minutes before measuring.
- Get Comfortable: Sit with your back supported, feet flat on the floor, and arm supported at heart level.
- Use the Cuff: Ensure the cuff is the right size and placed on bare skin as instructed.
- Take the Reading: Stay still and quiet while the machine inflates and deflates.
- Repeat: For accuracy, take 2-3 readings a minute apart and average the results.

Ideal Blood Pressure by Age
The standard blood pressure target for most adults should be below 120/80 mmHg but the following chart provides specific recommendations based on age.| Age Group | Ideal Blood Pressure (mmHg) | What to Watch For |
| 18–39 Years | 110–120 / 70–80 | This is the foundation phase. Build strong habits: reduce salt, stay active, avoid weight gain. |
| 40–64 Years | ≈120 / 80 | Blood pressure naturally creeps up. Regular checks are essential to catch early hypertension. |
| 65+ Years | ≈130 / 80 | Slightly higher targets may be acceptable, but require closer GP monitoring to avoid complications. |
Why blood pressure changes with age:
Blood pressure levels change throughout different stages of life because of natural changes in artery stiffness. The arteries lose their ability to stretch properly during each heartbeat and become more rigid which results in increased blood pressure inside the arteries. The process of monitoring becomes essential because we advance through different stages of life.Factors That Increase Your Risk of Hypertension
- Excess weight: Carrying extra weight puts strain on your system. Achieving and maintaining a healthy weight is essential for keeping your blood pressure in the healthy range.
- Maintaining a healthy diet: Maintaining a healthy diet plays a role in preventing hypertension. It is important to avoid processed foods and excessive sodium while ensuring you include a variety of vegetables, fruits and whole grains in your meals.
- Exercise: An inactive lifestyle directly contributes to high blood pressure. Engaging in activity and exercise is essential for maintaining optimal blood pressure levels.
- Smoking & Alcohol: Both smoking and alcohol consumption can cause spikes in blood pressure as well as long term effects. Taking steps to quit smoking and limiting alcohol intake can significantly lower the risk of developing hypertension.
- Chronic Stress: Chronic stress can lead to increased blood pressure due to the tension and constriction of blood vessels. Managing stress effectively is key in mitigating this risk factor.
- Family History: A family history of hypertension increases the likelihood of developing high blood pressure. It is important to be aware of your family’s history as it can help determine your risk factors.
- Underlying Conditions: Certain underlying conditions such as diabetes, kidney disease and sleep apnoea are associated with an increased likelihood of developing blood pressure. Identifying and managing these conditions appropriately is important for maintaining health.
Healthy Habits
- Follow a heart eating plan that includes an abundance of vegetables fruits, lean proteins, whole grains, healthy fats and oils. Limiting sodium intake, sugar consumption, alcohol consumption and processed food consumptions recommended.
- Engage in regular exercise by aiming for 150 minutes per week of moderate activities, like brisk walking, swimming, cycling or light strength training. These activities promote heart health. Keep your blood vessels functioning optimally.
- Maintaining a weight is important. Calculate your BMI to determine the weight range, for your height. By following a diet and engaging in exercise you can achieve effective weight management.
- Finding ways to manage stress is crucial. Consider activities such as yoga, mindfulness exercises, massage therapy, spending time in nature, nurturing relationships or even seeking therapy. These outlets for stress relief contribute to maintaining blood pressure.
- Monitoring your blood pressure at home is a practice. Investing in a home blood pressure monitor allows you to track your levels twice a month. This way you can detect any changes on. Take appropriate measures.
- It’s advisable to limit alcohol consumption and avoid smoking. Both of these habits not only have impacts on overall health but also directly elevate blood pressure levels. If quitting smoking is challenging there are aids that can assist with smoking cessation.
- Certain supplements may support blood pressure levels well. Consult with your doctor about incorporating magnesium, potassium, coenzyme Q10 and omega 3s into your diet.
- Knowing your family history is important when it comes to heart disease prevention and monitoring. If heart conditions run in your family, collaborate closely with your doctor to develop a prevention plan.
When to See a Doctor
Your GP needs to see you when:- Your blood pressure readings stay in the 'Elevated' or 'High' category.
- Your family history shows high blood pressure or heart disease.
- You experience ongoing headaches together with dizziness and vision problems.

What time of day should I measure my blood pressure?
The most suitable time for blood pressure measurement occurs during morning hours before food consumption and medication intake and before evening time. You should avoid caffeine and exercise and smoking for at least thirty minutes before taking your blood pressure reading.What’s considered dangerously high blood pressure reading?
A blood pressure reading of 180/120 mmHg or higher indicates a hypertensive crisis which requires immediate medical assistance.What’s considered low blood pressure?
A blood pressure reading below 90/60 mmHg is considered low but only becomes problematic when it causes dizziness or fainting or vision problems.Natural methods exist to help people lower their blood pressure levels.
Yes. Many people achieve significant blood pressure reduction through lifestyle changes which include salt reduction and increased vegetable consumption and regular exercise and weight management. However, if natural methods are not effective, they will require medical management to reduce their risk of high blood pressure.Does temperature affect blood pressure?
Yes. The hot Australian summer weather causes blood vessels to expand which results in lower blood pressure readings. The body responds to cold temperatures by narrowing blood vessels which leads to increased blood pressure.What is the best diet to maintain healthy blood pressure?
The DASH (Dietary Approach to Stop Hypertension) diet stands as the recommended eating plan for people who want to control their blood pressure. The diet requires you to consume fresh whole foods while reducing your intake of processed foods and saturated fats and salt. The DASH diet follows a traditional Australian eating pattern which focuses on vegetables and reduces salt content in meat products.Feeling sick and unsure why? Speak with a GP online in 15 minutes.
