How to Measure Blood Pressure at Home More Reliably
Accurate measurement is foundational. The American Heart Association recommends a validated automatic upper-arm cuff for home monitoring.
Before measuring
Avoid smoking, caffeine and exercise for 30 minutes beforehand, empty your bladder, and sit quietly for at least five minutes. Put the cuff on bare skin and support your arm at heart level.
Take repeat readings
The AHA recommends taking two readings one minute apart and recording the results. Measure at consistent times and share the log with your healthcare professional.
Do not change medication on your own
Home monitoring does not replace regular medical care. Do not stop prescribed blood-pressure medication based on home readings without consulting your healthcare professional.
Emergency threshold
If readings remain above 180/120 mm Hg and you have symptoms such as chest pain, shortness of breath, weakness, vision changes or difficulty speaking, the AHA advises calling emergency services.
