If your doctor told you to get your blood pressure down to 120 over 80, they weren’t wrong to say it. But after 60, chasing that exact number can, in some cases, do more harm than good. The number itself isn’t flawed — the problem is how broadly it’s been applied, often to people it was never actually tested on.
This isn’t an argument against treatment or medication. It’s about understanding where that widely-cited target came from, what changes in the body after 60 that makes a uniform number risky for some people, and what a more personalized target can look like depending on your age and health profile. (Based on the insights of Dr. Jason Collins)
Key Takeaways
- The 120/80 target came from studies on younger, healthier adults — not the typical person managing multiple conditions after 60.
- Aggressive blood pressure lowering in older adults is linked to more falls, dizziness, and kidney strain in real-world use.
- Cardiologists increasingly recommend a personalized target based on age, health conditions, and symptoms rather than one number for everyone.
- Symptoms like dizziness on standing, brain fog, and unusual fatigue can signal that a current blood pressure target is set too low for your body.
Where the 120/80 Target Actually Came From
For decades, researchers observed that adults with blood pressure around 120 over 80 tended to have fewer heart attacks and strokes, and that observation became the standard target. But most of the early studies behind that number were conducted on younger adults with healthy kidneys, healthy brains, and few or no other medications — not on someone in their late 60s or 70s managing two or three conditions and taking several prescriptions daily. The number isn’t wrong; it’s simply being generalized to a population it wasn’t originally built around.
What Happens to Your Arteries and Brain After 60
Arteries stiffen with age — think of the difference between a new, flexible rubber hose and one that’s spent a decade in the sun. Stiffer arteries mean the heart has to work harder to move blood, and the brain, kidneys, and heart gradually come to depend on a slightly higher baseline pressure to function normally. When blood pressure is pushed aggressively toward 120, some older adults can’t compensate, leading to dizziness, brain fog, fatigue, and unsteadiness.
This matters because falls in older adults are rarely minor. A 2019 review published in the Journal of the American Geriatric Society found that aggressive blood pressure lowering in older adults significantly increases the risk of falls and fall-related injuries — a risk that’s easy to overlook when the only thing being measured is the number on the cuff.
The Fine Print in the Major Blood Pressure Trials
The 2015 SPRINT trial, which studied over 9,000 adults averaging 68 years old, found that a target below 120 systolic reduced heart attacks and cardiovascular deaths compared to a target below 140. That finding pushed many physicians toward more aggressive targets in older patients. But the trial excluded anyone with diabetes, a prior stroke, dementia, advanced kidney disease, or significant frailty — meaning the participants were among the healthiest and most resilient older adults, not necessarily representative of the average person over 60.
Even within that healthier group, the lower target came with more dizziness, more fainting, more kidney problems, and more drops in blood pressure upon standing. A follow-up 2021 trial in China, the STEP trial, involving over 8,500 adults aged 60 to 80, found a similar pattern: real cardiovascular benefit from lower targets, alongside real side effects in everyday patients.
Finding Your Personal Blood Pressure Target
Many cardiologists now use a framework built around three broad profiles for older adults:
Profile one — ages 60 to 79, physically active, mostly independent, without major conditions like kidney disease or dementia, and without dizziness on standing. A target below 130 over 80 is generally appropriate, with meaningful cardiovascular benefit and relatively low side-effect risk.
Profile two — ages 60 to 79, but managing multiple conditions such as diabetes or kidney issues, or taking three or more medications, and sometimes feeling lightheaded. A target of 130 to 140 systolic is often considered safer; the 2021 American College of Cardiology guidelines note that more aggressive targets in this group can cause more harm than benefit.
Profile three — age 80 or older. Research generally supports a systolic target between 130 and 150, depending on day-to-day symptoms. Adults who comfortably sit at 120 without dizziness or fatigue may tolerate additional protection, but those who feel unsteady or foggy are often better served by the higher range.
Signs Your Current Target May Be Too Aggressive
Several everyday symptoms can indicate that a blood pressure target is set lower than the body can comfortably tolerate: dizziness on standing (especially in the morning), persistent brain fog, unusual tiredness despite adequate sleep, a sense of unsteadiness while walking, readings that regularly dip below 100 systolic, and muscle cramps or electrolyte imbalances, which can occur with certain diuretic medications. None of these are something to dismiss as “just getting older” — they’re worth discussing with a physician.
What to Do Before Your Next Doctor’s Appointment
Three practical steps can make a real difference in that conversation. First, identify which of the three profiles best matches your current life — not how active you were a decade ago. Second, track how you feel alongside your blood pressure readings for a week; a log showing real-world symptoms is often more informative to a doctor than a single reading taken in an exam room. Third, ask a specific question: “Given my age, my conditions, and the symptoms I’ve been tracking, what is my personalized blood pressure target?” That question shifts the conversation from a generic guideline to a target built around the individual.

Frequently Asked Questions
Does this mean I should stop trying to lower my blood pressure?
No. Blood pressure medication and management still meaningfully reduce cardiovascular risk. The point isn’t to avoid treatment — it’s to make sure the specific target you’re aiming for actually fits your age, health conditions, and how you feel day to day.
Should I adjust my medication on my own based on this information?
No — never change or stop a blood pressure medication without consulting your doctor first. This article is meant to help you have a more informed conversation with your physician, not to replace their guidance.
What if my doctor disagrees with these profiles?
Your doctor knows your full medical history and may have specific reasons for your current target. These profiles are a general framework increasingly used in cardiology, not a replacement for individualized medical judgment — bring up the conversation, but trust your physician’s assessment of your specific situation.
How long should I track my symptoms before bringing them to my doctor?
About a week is usually enough to show a meaningful pattern between your readings and how you feel, though if you experience concerning symptoms like fainting or severe dizziness, don’t wait — contact your doctor right away.
Quick Start Checklist
- ☐ Identify which of the three age/health profiles matches your life today
- ☐ Track your blood pressure readings daily for 7 days
- ☐ Log how you feel (dizzy, foggy, tired, fine) alongside each reading
- ☐ Note any readings that dip below 100 systolic
- ☐ Watch for muscle cramps or signs of electrolyte imbalance
- ☐ Write down your specific question for your doctor in advance
- ☐ Ask: “What is my personalized blood pressure target?” at your next visit

Blood pressure targets should always be determined individually with a licensed physician, taking into account your full medical history, current medications, and symptoms. Never adjust or stop a blood pressure medication without first consulting your doctor. If you experience chest pain, sudden severe dizziness, fainting, or signs of stroke, seek emergency medical attention immediately.
