That headline is referring to falsely elevated blood pressure readings, which can happen even if your actual blood pressure is normal. Understanding these mistakes is important to avoid unnecessary worry or misdiagnosis.
🩺 Common mistakes that give false high blood pressure readings
- Caffeine or nicotine right before measurement
- Both temporarily raise blood pressure. Wait 30–60 minutes before checking.
- Stress or anxiety
- “White coat hypertension” occurs when readings are higher in a doctor’s office.
- Full bladder
- A full bladder can raise readings by 10–15 mmHg.
- Wrong cuff size
- Too small or too large cuffs give inaccurate results.
- Arm position
- Keep your arm at heart level; below or above changes readings.
- Crossed legs
- Sitting with legs crossed can increase systolic pressure by a few points.
- Talking or moving during measurement
- Stay still and silent for accurate results.
- Not resting before measurement
- Sit quietly for 5 minutes before checking.
- Recent exercise
- Blood pressure rises during and immediately after activity.
- Incorrect back/foot support
- Sit with your back supported and feet flat on the floor.
- Taking readings at inconsistent times
- Blood pressure naturally fluctuates; measure at the same time each day for consistency.
đź’ˇ Tips for accurate readings
- Take two readings, 1–2 minutes apart, and average them.
- Use a validated home monitor if tracking at home.
- Keep a log to show your doctor trends, not single numbers.
