Fitness watches, not only track calories burned, steps, fitness progress, etc., but also can measure blood pressure (BP) which is the pressure of the blood in the arteries, related to the rate of your heartbeat and the elasticity of your arteries. Wearing one with a BP monitor is important to detect heart problems and get a clear picture of your heart health.

The American Heart Association, recommends anyone with high blood pressure to monitor his or her blood pressure at home. It can be measured using a sphygmomanometer which is used at the doctor’s office or a home blood pressure monitor. However, if you prefer to use a fitness watch with a BP monitor you are in the right place. So how do they measure blood pressure?

Many fitness trackers take oscillometric readings in the morning and evening. This automatic blood pressure measurement consists of an electronic pressure sensor that calculates estimates of systolic and diastolic pressures. Other fitness trackers with blood pressure monitors use a PPG or photoplethysmogram.

A PPG is a heart rate sensor that uses a pulse oximeter. This sensor illuminates the skin and measures any changes in light absorption. Besides, it also uses ECG readings that work with algorithms. However, they don’t have an inflatable cuff, and readings are not as accurate as the sphygmomanometer which is used at the doctor’s office. If you follow the user’s guide as directed, they can be accurate enough and you can familiarize yourself with the product.

These fitness trackers with blood pressure look just like a smartwatch or fitness trackers. In general, they are easy to use and the blood pressure can be measured at any time.

How to measure your blood pressure using a smart bracelet

Below are some tips on measuring your blood pressure using a smart fitness gadget that can help you prevent or monitor any heart problems.

Many types of wearable devices measure blood pressure. The readings obtained will vary from device to device. Here are the 15 tips to correctly measure it with a fitness tracker.

  1. Read the user’s manual to become familiar with your device
  2. Make sure your fitness tracker has good battery life.
  3. Avoid any caffeine, cigarettes, or physical activities before measuring your blood pressure.
  4. Sit down and relax all the time you need. Don’t think about anything.
  5. Wear your device so that it is snug.
  6. Your arm should be resting on a flat surface such as a table with the upper arm at heart level. This will give you a better reading. I tried resting my arm on my lap and resting my arm on my chest but the readings athe re higher.
  7. You can measure your blood pressure two times more and compare the results.
  8. Check your results. If your blood pressure is less than 90/60 that can be low blood pressure. From 91/61 to 119/79 is normal. 120/80 or less to 129/80 or less is considered elevated. From 130/80-89 to 139/80-89 is high blood pressure stage 1. From 140 or higher is high blood pressure stage 2. Blood pressure higher than 180/higher than 120 is considered a hypertensive crisis. In this case, it is recommended to go to the doctor.
  9. Depending on your fitness tracker and application you can either check your blood pressure one time or continuously.

The best way to know if a fitness tracker with BP is accurate

Do you want to know if your smartwatch with the blood pressure tracker is accurate enough? The best way to check if your device is accurate is to bring it to the doctor’s office. Measure your blood pressure with your fitness watch and compare your doctors’ readings. However, because blood pressure is not an absolute number results may be approximate or close enough.

However, keep in mind that blood pressure changes during the day depending on the weather, food that you eat, genetics, age, weight, mood, medication, physical activity, stress levels, and alcohol. Blood pressure can be lower at night and will rise before you wake up. It will continue to rise during the day picking up in the afternoon.

When you measure your blood pressure either at the doctor’s office or with a fitness tracker we are looking for any changes or patterns. You may discover that eating certain foods or doing specific physical activity may increase or decrease your blood pressure.

My experience with a smart wristband that tracks blood pressure

Wearing a fitness watch with blood pressure like the Onston fitness tracker (currently unavailable) for almost a year has transformed my life. Experiencing panic attacks in the past and having a high blood pressure history in my family I always knew the importance of monitoring my blood pressure. It has a quite low rating but it has worked for me plus it is worth the price.

I compared my wearable fitness readings with a Samsung Healthy Living BD-3000S BP monitor (discontinued) that I had since 2003 and that I had already shown to my doctor. Readings also matched my doctor’s. Please note that Samsung’s blood pressure monitor is currently unavailable – Samsung Healthy Living closed in 2009.
