High blood pressure is often called the silent killer — and for good reason. It produces no symptoms. You can feel completely fine while it quietly damages your heart, brain, kidneys, and arteries. And after 60, it becomes dramatically more common and dramatically more consequential.
Roughly 70% of adults over 65 have high blood pressure. Yet despite being so prevalent and so well understood, it remains poorly controlled in a significant proportion of older adults — often because of outdated beliefs about what numbers are acceptable, confusion about medications, or simply not knowing what lifestyle changes actually move the needle.
This article covers what you actually need to know: what your numbers mean, what the current evidence says about target levels for older adults, and what you can realistically do — both with and without medication — to protect yourself.
Understanding Your Numbers
Blood pressure is expressed as two numbers. The top number — systolic pressure — measures the force your heart exerts when it beats and pushes blood through your arteries. The bottom number — diastolic pressure — measures the pressure in your arteries between beats, when your heart is at rest.
For most adults, the current guideline threshold for high blood pressure (hypertension) is 130/80 mmHg or above. This was lowered from the previous threshold of 140/90 in 2017 by the American College of Cardiology, based on strong evidence that even modestly elevated pressures significantly increase cardiovascular risk over time.
For older adults, the picture is somewhat more nuanced. Very aggressive blood pressure lowering in frail elderly patients can cause problems — including dizziness, falls, and reduced blood flow to organs that depend on adequate pressure to function. The current consensus for adults over 80 is generally a target of below 150/90, though this varies significantly based on individual health status and should be discussed with your own physician.
"For most adults in their 60s and 70s who are otherwise healthy, a blood pressure target of below 130/80 is appropriate and beneficial. The evidence for treating to this level is strong. Don't let anyone tell you that 140 or 150 systolic is 'fine for your age.'"

Why Blood Pressure Rises With Age
As we age, the large arteries that carry blood away from the heart naturally become stiffer and less elastic. This is partly due to the accumulation of calcium deposits and changes in the structural proteins — collagen and elastin — that give arteries their flexibility. Stiffer arteries mean higher pressure is required to push blood through them, which is why systolic pressure tends to rise with age even in otherwise healthy people.
Other contributing factors include declining kidney function (the kidneys play a major role in regulating blood pressure), changes in the nervous system that controls blood vessel tone, increased salt sensitivity with age, and the cumulative effects of lifestyle factors — excess weight, physical inactivity, high sodium intake, alcohol, and chronic stress — that may have been building for decades.
The Lifestyle Changes That Actually Make a Difference
Medication is often necessary to control blood pressure, and there's no shame in that. But lifestyle changes are not just a nice supplement to medication — they are genuinely powerful interventions in their own right, and they work even in people who are already on blood pressure medication.
Reduce sodium intake. The evidence connecting high sodium intake to elevated blood pressure is overwhelming. The average adult consumes far more sodium than they realise — most of it not from the salt shaker but from processed foods, restaurant meals, bread, canned goods, and condiments. Reducing sodium intake to below 1,500mg per day produces clinically meaningful blood pressure reductions in most older adults.
Follow the DASH diet. The Dietary Approaches to Stop Hypertension diet is one of the most rigorously studied dietary interventions in medicine. It emphasises vegetables, fruits, whole grains, lean proteins, and low-fat dairy while reducing saturated fat, red meat, and sweets. Studies consistently show it lowers systolic blood pressure by 8–14 mmHg — comparable to some medications.
Exercise regularly. Aerobic exercise — walking, swimming, cycling — lowers blood pressure by improving the elasticity of blood vessels and reducing the resistance blood faces as it flows through the circulatory system. Even modest amounts help. A meta-analysis of 391 studies found that exercise reduces systolic blood pressure by an average of 4–9 mmHg — significant reductions for most people.
Limit alcohol. Even moderate alcohol consumption raises blood pressure. The relationship is dose-dependent: the more you drink, the higher your blood pressure. Limiting intake to no more than one standard drink per day for women and two for men is the current recommendation, though lower is better if blood pressure control is a concern.
Manage weight. Each kilogram of excess weight raises blood pressure by approximately 1 mmHg. Even modest weight loss — 5 to 10% of body weight — produces meaningful blood pressure reductions in overweight individuals.
Manage stress. Chronic psychological stress activates the sympathetic nervous system, which constricts blood vessels and raises heart rate and blood pressure. Over time, this sustained activation contributes to structural changes in the cardiovascular system. Regular relaxation practices — whether meditation, deep breathing, yoga, or simply regular time in nature — have measurable effects on blood pressure.
A Note on Home Monitoring
If you have high blood pressure or are at risk, buying a reliable home blood pressure monitor is one of the most useful health investments you can make. Blood pressure measured at home, away from the anxiety of a clinical setting, is often more representative of your true average than readings taken at the doctor's office.
Check your blood pressure at the same time each day — ideally morning and evening — after sitting quietly for five minutes. Keep a log to share with your doctor. Consistent home monitoring gives you and your physician far better information to work with than occasional clinic readings.
"Controlled blood pressure is one of the most powerful things you can do for long-term brain health, kidney health, and cardiovascular health. It's genuinely worth taking seriously."
The Bottom Line
High blood pressure after 60 is common, but it is not inevitable and it is not something to accept passively. The combination of appropriate medication when needed and meaningful lifestyle modification can bring blood pressure to safe levels in the vast majority of people — and the long-term benefits for heart, brain, and kidney health are substantial.
Know your numbers. If they're elevated, take it seriously. Talk to your doctor about your target, and be proactive about both lifestyle changes and medication management. This is one area where getting it right genuinely adds years to your life — and life to your years.
