Understanding Blood Pressure — What Every Australian Over 60 Should Know

Blood pressure is one of the most commonly discussed health numbers in medicine — and one of the least well understood by the people it affects most. For Australians over 60, understanding blood pressure, what the numbers actually mean, and how to manage it effectively is genuinely one of the most important health investments available. Here’s a plain English guide to everything you need to know.

What Is Blood Pressure?

Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps it around your body. It’s measured in millimetres of mercury — mmHg — and recorded as two numbers:

Systolic pressure — the top number — measures the pressure in your arteries when your heart beats and pumps blood.

Diastolic pressure — the bottom number — measures the pressure in your arteries between beats, when your heart is resting.

A reading is written as systolic over diastolic — for example, 120/80 mmHg — and both numbers matter.

What Do the Numbers Actually Mean?

Reading	Category	What it means
Below 120/80	Normal	Healthy range
120-129/below 80	Elevated	Worth monitoring
130-139/80-89	High — Stage 1	Lifestyle changes recommended
140+/90+	High — Stage 2	Medical treatment likely needed
Below 90/60	Low	May cause dizziness or fainting

For most adults over 60, a target blood pressure of below 130/80 is generally recommended, though your GP will advise on your individual target based on your overall health picture.

Why Blood Pressure Matters More After 60

Blood pressure naturally tends to rise with age as arteries gradually stiffen and lose some of their flexibility. This makes hypertension — consistently high blood pressure — increasingly common after 60, and increasingly important to manage.

What high blood pressure can cause if left unmanaged:

• Heart attack
• Stroke — one of the leading causes of disability in older Australians
• Heart failure
• Kidney damage
• Vision loss
• Cognitive decline and increased dementia risk

The particularly concerning aspect of high blood pressure is that it typically produces no symptoms — it is often called the “silent killer” precisely because most people with hypertension feel completely well right up until a serious event occurs. This is why regular monitoring matters so much.

What Causes High Blood Pressure?

For most people, high blood pressure develops gradually over time without a single identifiable cause — this is called primary or essential hypertension. Several factors increase the risk:

• Age — blood pressure tends to rise naturally with age
• Family history — genetics play a significant role
• Being overweight or obese
• Physical inactivity
• A diet high in salt
• Excessive alcohol consumption
• Smoking
• Chronic stress
• Certain medications — including some common pain relievers and cold and flu medications

In some cases high blood pressure has an identifiable underlying cause — such as kidney disease or a hormonal condition — and treating that cause can resolve the blood pressure issue directly.

How Is Blood Pressure Measured?

Blood pressure is measured using a device called a sphygmomanometer — either manually by a healthcare professional or automatically using a home monitoring device.

At a GP appointment: A single reading at the GP is useful but not always definitive — blood pressure can temporarily rise due to the anxiety of a medical appointment, a phenomenon known as white coat hypertension. Most GPs take multiple readings over time before diagnosing hypertension.

At home: Home blood pressure monitors are widely available, easy to use, and genuinely valuable for tracking blood pressure patterns over time. As I explore in the best technology for Australians over 60 — home health monitoring devices have become significantly more accessible and user friendly in recent years.

When measuring at home:

• Sit quietly for five minutes before measuring
• Sit with your back supported and feet flat on the floor
• Rest your arm on a flat surface at heart level
• Take two or three readings one to two minutes apart and average them
• Measure at the same time each day — morning and evening if possible
• Keep a record to share with your GP

How to Lower Blood Pressure Without Medication

For many people, particularly those with elevated or Stage 1 hypertension, lifestyle changes can meaningfully reduce blood pressure without medication.

Diet: Reducing salt intake is one of the single most effective dietary changes — most Australians consume far more sodium than recommended, largely through processed foods. The DASH diet — Dietary Approaches to Stop Hypertension — is specifically designed to reduce blood pressure through food choices, emphasising vegetables, fruits, whole grains, and lean protein while reducing saturated fat and sodium.

Physical activity: Regular moderate exercise — such as brisk walking for 30 minutes most days — is one of the most consistently effective lifestyle interventions for reducing blood pressure. As I wrote in the best low impact exercises for Australians over 60 — regular movement benefits health in ways that go far beyond weight management alone.

Weight management: Even modest weight loss — five to ten percent of body weight — can produce meaningful reductions in blood pressure for those who are overweight.

Limiting alcohol: Reducing alcohol intake to within recommended guidelines — no more than two standard drinks per day — can meaningfully reduce blood pressure.

Quitting smoking: Smoking raises blood pressure and damages blood vessels — quitting is one of the most impactful single health decisions available.

Managing stress: Chronic stress contributes to elevated blood pressure. Stress management strategies — whether mindfulness, regular physical activity, adequate sleep, or social connection — support blood pressure management alongside their other wellbeing benefits.

Limiting caffeine: While the relationship between caffeine and blood pressure is complex and varies between individuals, reducing high caffeine intake is worth discussing with your GP if blood pressure management is a priority.

Blood Pressure Medications

When lifestyle changes aren’t sufficient to bring blood pressure to a safe level, medication is often recommended. Several classes of blood pressure medication are commonly used, and finding the right medication or combination of medications sometimes takes time and adjustment.

Common types include:

• ACE inhibitors
• Angiotensin receptor blockers
• Calcium channel blockers
• Diuretics — sometimes called water pills
• Beta blockers

If you’re prescribed blood pressure medication, taking it consistently as directed is genuinely important — stopping suddenly or missing doses can cause significant blood pressure fluctuations. If you’re experiencing side effects, speak with your GP about alternatives rather than stopping medication independently.

Low Blood Pressure — Worth Knowing About Too

While high blood pressure receives the most attention, low blood pressure — hypotension — is also worth understanding, particularly for older adults.

Orthostatic hypotension — a sudden drop in blood pressure when standing up — is particularly common after 60 and can cause dizziness and falls. Standing up slowly from a seated or lying position significantly reduces this risk.

If you regularly feel dizzy when standing, mention this to your GP — it’s worth investigating and managing rather than accepting as normal.

When to See Your GP

See your GP if:

• You haven’t had your blood pressure checked in the past 12 months
• You have a family history of high blood pressure, heart disease, or stroke
• You’re experiencing regular headaches, dizziness, or visual disturbances
• Your home blood pressure readings are consistently above 140/90
• You’re on blood pressure medication and experiencing side effects

Regular blood pressure monitoring should be a routine part of every Australian over 60’s healthcare — not something that only happens when symptoms appear.

The Bottom Line

Blood pressure management is one of the most impactful things an Australian over 60 can do for their long term health. It’s largely silent, largely preventable, and largely manageable with the right combination of lifestyle choices and medical support.

Get it checked. Monitor it at home. Make the lifestyle changes that genuinely help. And work with your GP to find the right approach for your individual situation.

The effort is genuinely worth it.
