How to measure your blood pressure at home (and why you should)
One reading at the clinic isn't enough. Here's how to build a real picture of your blood pressure with a $40 cuff.
Blood pressure fluctuates all day. A single clinic reading — often taken after you rushed in from parking — can be 10–15 points off your true average. That's the difference between 'normal' and 'stage 1 hypertension.'
The setup
- Buy a validated upper-arm cuff (Omron and A&D are reliable). Skip wrist and finger devices.
- Sit for 5 minutes first. Feet flat, back supported, arm at heart level.
- Take two readings, one minute apart. Log the average.
- Do this morning and evening for 7 days before your next appointment.
What the numbers mean
- Under 120/80 — optimal.
- 120–129 / under 80 — elevated. Lifestyle matters.
- 130–139 / 80–89 — stage 1 hypertension.
- 140+ / 90+ — stage 2. Bring this data to a clinic soon.
