What the Numbers Mean
A blood pressure reading consists of two numbers expressed in millimeters of mercury (mmHg). The first, or systolic value, captures peak arterial pressure during a heartbeat. The second, or diastolic value, reflects pressure between beats. Understanding both matters, especially as you age.
| Normal blood pressure target | Below 120/80 mmHg (American Heart Association) |
| Stage 1 hypertension range | 130–139/80–89 mmHg (2017 ACC/AHA Guidelines) |
| Stage 2 hypertension range | 140/90 mmHg or higher (2017 ACC/AHA Guidelines) |
| Hypertension prevalence in adults 60+ | Approximately 70% (CDC National Center for Health Statistics) |
| Recommended home measurement frequency | Twice daily, same times each day (American Heart Association) |
| Readings before logging an average | At least 2–3 readings per session (American Heart Association home monitoring guidance) |
For most adults, clinicians use a standard framework:
- Normal: Below 120/80 mmHg
- Elevated: 120–129 systolic, and below 80 diastolic
- Stage 1 Hypertension: 130–139/80–89 mmHg
- Stage 2 Hypertension: 140/90 mmHg or higher
- Hypertensive Crisis: Above 180/120 mmHg — requires immediate medical attention
In older adults, isolated systolic hypertension — where systolic is elevated but diastolic is normal or low — is particularly common due to age-related arterial stiffening. This is addressed in more detail in our decade-by-decade healthy aging overview.
Systolic pressure
The top number in a blood pressure reading. It measures the force your heart exerts on artery walls each time it beats. Elevated systolic pressure is particularly significant in older adults.
Diastolic pressure
The bottom number in a blood pressure reading. It reflects arterial pressure between heartbeats, when the heart is at rest. Isolated low diastolic pressure in seniors may also warrant monitoring.
Hypertension
Clinically elevated blood pressure, generally defined as readings consistently at or above 130/80 mmHg under American Heart Association guidelines. It is a major modifiable risk factor for heart disease and stroke.
Orthostatic hypotension
A sudden drop in blood pressure when standing up from a seated or lying position. It is more common in older adults and can cause dizziness or fainting. A healthcare provider should evaluate persistent episodes.
White coat hypertension
Elevated blood pressure readings that occur only in clinical settings, likely due to anxiety, while home readings remain normal. It can complicate diagnosis and should be discussed with a clinician.
Pulse pressure
The numerical difference between systolic and diastolic readings. A widening pulse pressure with age often reflects increased arterial stiffness and may be clinically relevant.
How Blood Pressure Changes With Age and Why It Matters
Blood vessels naturally lose some elasticity over time, which tends to push systolic readings upward. This is why hypertension affects an estimated 70% of Americans aged 60 and older, according to CDC data. The condition often develops gradually without noticeable symptoms, which is why regular monitoring is considered an important part of routine care.
~70%
Adults over 60 with hypertension
According to CDC National Center for Health Statistics data, roughly 70% of Americans aged 60 and older have high blood pressure.
130/80
mmHg threshold for hypertension diagnosis
The 2017 ACC/AHA guidelines set this as the clinical threshold for hypertension, lowering the previous 140/90 benchmark.

U.S. adults with uncontrolled high blood pressure
CDC estimates suggest a substantial proportion of people with hypertension do not have it adequately controlled.
Age-related changes also increase the risk of orthostatic hypotension — a sudden drop in pressure when standing. This can contribute to falls, a leading cause of injury among older adults. Certain medications, including some used to treat hypertension itself, may increase this risk. Always raise concerns about dizziness with your healthcare provider rather than adjusting medications independently.
Blood pressure does not exist in isolation. Conditions such as type 2 diabetes can compound cardiovascular risk, which is why coordinated management matters. See Living Well With Type 2 Diabetes After 60 for context on managing multiple conditions in later life.

Monitoring at Home: How to Get Accurate Readings
Home Readings Are Not a Substitute for Clinical Care
Home blood pressure monitors can be a valuable tool for tracking trends, but they do not replace regular clinical assessments. Readings taken at home should be shared with your healthcare provider, who can interpret them in the context of your full health history, medications, and risk factors. If you experience very high readings, chest pain, or sudden severe headache, seek emergency care immediately.
Home monitoring can help identify patterns that a single office visit may miss — including white coat hypertension or readings that fluctuate throughout the day. To obtain reliable measurements:
- Rest quietly for at least five minutes before measuring.
- Sit with your back supported, feet flat on the floor, and arm at heart level.
- Avoid caffeine, exercise, and smoking for 30 minutes beforehand.
- Take two or three readings, one minute apart, and record the average.
- Measure at the same times each day — typically morning and evening.
- Bring your log or device to all clinical appointments.
Upper-arm cuff monitors are generally more accurate than wrist models. Ask your healthcare provider to validate your home device against an in-office reading to confirm calibration.
Blood pressure readings are one of several screenings worth discussing regularly with your doctor. Annual Health Checks Worth Prioritising After Age 65 outlines the full range of assessments commonly recommended for adults over 65.
Lifestyle Factors That Influence Blood Pressure
Research consistently identifies several modifiable lifestyle factors that support healthy blood pressure levels. While no single change is a guaranteed solution, clinicians often point to the following as worthwhile areas to explore in partnership with your care team:
- Sodium intake: Dietary sodium has a well-documented association with blood pressure in many individuals. Nutrition labels are a practical tool for tracking intake — our guide on reading a nutrition label after 60 explains what to look for.
- Physical activity: Regular moderate exercise is associated with lower blood pressure in population studies, though any new exercise regimen should be discussed with a clinician first.
- Alcohol consumption: Heavy alcohol use is linked to elevated blood pressure; moderation is generally advised.
- Sleep quality: Poor or disrupted sleep may contribute to blood pressure variability. Addressing sleep issues is a reasonable topic to raise with your doctor.
- Stress management: Chronic stress can contribute to sustained elevations. Evidence-based approaches such as mindfulness and structured relaxation may support overall cardiovascular wellness.
