Ensuring accurate results from your smartwatch is crucial for maximizing its benefits. Sometimes, inaccurate readings may be attributed to improper placement on your wrist. Follow these steps to ensure your smartwatch is properly worn for precise data:


1. Positioning:

  • Place the smartwatch on the top of your wrist, aligning it with the bone that protrudes slightly on the side.
  • Ensure it's snug but not too tight. You should be able to slide one finger under the band.

2. Alignment:

  • The sensors on the back of the smartwatch need to make direct contact with your skin. Adjust the band to sit flat against your wrist.

3. Not Too High or Too Low:

  • The watch should sit about a finger's width above your wrist bone, not directly on it, and not halfway up your forearm.

4. Avoid Slippage:

  • If the smartwatch tends to slide around during movement, it may lead to inaccurate readings. Adjust the band for a secure fit.

5. Clean the Sensors:

  • Ensure the sensors on the back of the watch and your skin are clean. Sweat, dirt, or moisture can interfere with readings.

6. Check for Tightness:

  • After wearing it for a while, check the snugness. It might need a slight adjustment if it feels too loose or too tight.

Conclusion: Properly wearing your smartwatch is fundamental to obtaining precise and reliable data. By following these steps, you'll optimize the accuracy of your smartwatch's readings and make the most out of its features.

For measuring blood pressure, smartwatches use the optical heart rate sensor.

It detects the time it takes for a pulse to travel from the heart to the wrist. It is also known as Pulse Transit Time (PTT), based on which it shows the blood pressure readings. If the blood pressure is high, the pulse transit time is faster and if the blood pressure is low, the pulse transit time is slow.

Measuring blood pressure is much harder than tracking heart rate and rhythm, and getting it right is arguably even more important. 

Squeeze-free methods
Having more ways to easily take blood pressure measurements at home could be a big benefit to people with hypertension (high blood pressure) or other concerns. Pressure measurements taken exclusively in a doctor’s office are often unreliable: some people have higher blood pressure in-office because they’re anxious about the visit, while other people have masked hypertension — high blood pressure at home, but normal blood pressure at the doctor. 

What is the correct way to measure blood pressure?
 Use this checklist:

  • Don’t eat or drink anything 30 minutes before you take your blood pressure.
  • Empty your bladder before your reading.
  • Sit in a comfortable chair with your back supported for at least 5 minutes before your reading.
  • Put both feet flat on the ground and keep your legs uncrossed.
  • Rest your arm with the cuff on a table at chest height.
  • Make sure the Smartwatch is snug but not too tight. The watch should be against your bare skin, not over clothing.
  • Do not talk while your blood pressure is being measured.

In one position it repels, in the other it attracts the magnetic charger.
