Smartwatches can do a lot for you, but their most unique feature may not be their fitness tracking—it’s the fact that they now offer medical-grade blood pressure readings. This means that if you’re worried about developing high blood pressure, you can monitor your readings and set reminders to consult your doctor if those levels increase. But, how accurate are these readings? And how to get best blood pressure reading from smartwatch? Today, we will discuss this particular topic.
How does a smartwatch read blood pressure?
A smartwatch uses its sensors to detect changes in blood pressure. These types of watches use a PPG sensor, AKA photoplethysmography, that uses light to measure your pulse.
Then, the watch can use an algorithm to estimate the user’s blood pressure.
The watch can also use its sensors to detect other changes in the body, such as heart rate and skin temperature. By constantly monitoring these and other vital signs, the smartwatch can provide a wealth of information about the user’s health and well-being.
How accurate is the blood pressure reading of a smartwatch
There is no definitive answer to how accurate the blood pressure reading of a smartwatch is. Studies have yielded mixed results, with some finding that the readings are reasonably accurate and others finding that they are not.
The accuracy of a smartwatch’s blood pressure readings may depend on factors such as the model of the smartwatch, how it is calibrated, how it is worn, and the individual user’s physiology. A blood pressure reading obtained from a smartwatch may not be the most accurate.
To get the most accurate reading possible from a smartwatch, it is recommended to follow the instructions for use with the device. Generally, it is advised to take readings at the same time each day and to avoid taking readings after strenuous activity or before bedtime. With some devices, it may also be necessary to calibrate the device regularly to ensure accuracy.
How to get blood pressure reading from smartwatch
When using a smartwatch to measure your blood pressure, the blood pressure cuff should be as tight as possible. This will get your reading to the most accurate measurement. Follow the below tips to get the best blood pressure reading from a smartwatch.
1. Wrist Position
For the most accurate blood pressure readings, it is important to position your wrist correctly with your heart. The best position is to keep your wrist at the level of your heart. To do this, bend your elbow and position your forearm so that your wrist is level with the centre of your chest. Wait 10min before reading.
2. Blood Pressure Cuff
If you’re using a smartwatch to track your blood pressure, it’s important to use a cuff that’s the right size for your arm. If the cuff is too large, it won’t be able to get an accurate reading. If the cuff is too small, it will be uncomfortable and may cause bruising.
To get the best reading, wrap the cuff around your arm so that the bottom edge is about an inch above your elbow. Make sure the cuff is snug, but don’t wrap it too tight. Two fingers could perhaps fit underneath the cuff.
3. Relax
Ease yourself and do not move your arm during the reading. Avoid eating, drinking caffeine, smoking, or exercising within 30 minutes of taking your blood pressure.
This may seem obvious, but it’s important to be as relaxed as possible when taking your blood pressure reading. If you’re tense or anxious, your readings will likely be higher than they should be.
4. Take multiple readings
It’s not uncommon for blood pressure readings to fluctuate, so it’s a good idea to take multiple readings throughout the day and average them out.
5. Position the smartwatch rightly
Your smartwatch should be positioned on your wrist, about an inch above your wrist bone. The bottom of the watch should be level with your palm. For the best blood pressure reading, make sure the watch is snug but not too tight.
6. Reading Blood Pressure
Smart watches are equipped with sensors that can measure your blood pressure. To get the most accurate reading, it is important to follow the instructions that come with your device.
When you are ready to take your reading, sit down and relax for a few minutes. Then, place your watch on your wrist and make sure that the sensor is in contact with your skin. Once the sensor is activated, you will see your blood pressure readings on the screen.
If you are concerned about your blood pressure, it is always best to consult with your doctor.
When not to use the smartwatch for blood pressure reading
There are certain times when it is not advisable to use the smartwatch for blood pressure reading.
The smartwatch is not recommended for blood pressure readings when or if you:
– Have just exercised
– Are pregnant
– Have a pacemaker,
– Have diabetes
– Have heart disease
– Have recently suffered a heart attack or a stroke
If you have any of these conditions or any other medical conditions, please consult with your physician before using the smartwatch for blood pressure reading.
Also, avoid using the watch during strenuous activity, as this can raise your blood pressure. And be sure to check your readings against a traditional blood pressure cuff to ensure accuracy.
