A good blood pressure reading is typically between 90/60 mmHg and 120/80 mmHg. This range indicates healthy blood flow and reduces risks of cardiovascular diseases.
Blood pressure measures the force of blood against artery walls during heartbeats (systolic) and between beats (diastolic). It's expressed as two numbers: systolic over diastolic. The American Heart Association (AHA) notes that consistent readings above 120/80 mmHg may indicate hypertension, while readings below 90/60 mmHg could signal hypotension.
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | 90-120 | 60-80 |
| Elevated | 120-129 | 80-89 |
| Stage 1 Hypertension | 130-139 | 80-89 |
| Stage 2 Hypertension | 140+ | 90+ |
| Hypotension | Below 90 | Below 60 |
High blood pressure damages arteries over time, increasing risks of heart disease, stroke, and kidney failure. The Mayo Clinic reports that untreated hypertension can lead to heart attacks or aneurysms. Conversely, low blood pressure may cause dizziness, fainting, or insufficient blood flow to important organs.
Many assume only high blood pressure is dangerous, but low blood pressure can also pose risks. While a reading of 110/70 mmHg might seem ideal, it could indicate poor circulation or dehydration in some individuals. Factors like age, genetics, and lifestyle influence what's considered healthy for each person.
During a routine checkup, my blood pressure was measured at 115/75 mmHg. The nurse confirmed this was within the normal range, but she noted that my resting heart rate was slightly elevated. She recommended monitoring both metrics over time to ensure consistency.
