Use a blood pressure monitor to check your reading
A normal reading is usually below 120/80 mmHg
Elevated blood pressure is typically 120–129/<80 mmHg
High blood pressure is usually 130/80 mmHg or higher
Repeat the measurement after resting for 5 minutes
Take at least 2 readings, 1 minute apart
Check readings on different days for confirmation
Watch for symptoms such as headache, dizziness, blurred vision, chest pain, or shortness of breath
Seek medical care if blood pressure is 180/120 mmHg or higher
See a healthcare professional if readings are repeatedly high
