The best fitness bracelets with blood pressure and pulse measurement

Every year, smart bracelets get new features, and old ones only get better. A heart rate monitor is a feature that is rightfully considered standard for many trackers. It is important for athletes, as it allows you to monitor the effectiveness of training and adjust them. But for people who do not play sports (and this is especially true for the older generation), having a blood pressure monitor is more important.

It can be used to measure blood pressure. Disputes regarding the accuracy of such measurements do not stop, but even if there are errors, fitness bracelets with blood pressure measurements allow you to take timely measures to correct it, and they are more convenient to use than monitoring with a professional tonometer.

Below is a review of the best smart bracelets with blood pressure and heart rate measurements.

Smart Band M4

• Display: 0.95 inch, TFT, 240 x 120
• Autonomy: up to 7 days
• Weight: 20 grams

Price: from 1,035 rubles

The most inexpensive fitness bracelet that allows you to measure blood pressure. It is often advertised under different names. On AliExpress the price starts from $5. Visually, the device resembles the Xiaomi Mi Smart Band 4, although naturally it is inferior in build quality. But it has much more functions: the device measures pulse, monitors sleep quality, and provides information about pressure and saturation. You can also set alerts for calls and messages, and the system has several sports modes.

In the reviews, buyers are mostly satisfied. Still, for that kind of money it’s very nice to get such a functional device. There are some errors when measuring pressure, but they are quite expected.

Among the disadvantages, we can highlight the unfinished application that works with glitches. In addition, there is no manual in Russian.

This model is ideal for picky users: elderly people who want to quickly respond to increased blood pressure, or children who simply want to monitor their activity.

Advantages:

When playing sports, you should take a fitness bracelet with a high level of moisture protection - however, sweat or raindrops while jogging can have a detrimental effect on the operation of the device.

Features of the models

Multifunctional accessories are useful for both young people involved in sports and girls watching their figure, pensioners for monitoring their health, and residents of megacities struggling with physical inactivity. Smart watches quickly measure vital parameters in real time and transmit them to the display and to a synchronized smartphone application.

The trackers use a screening method of non-invasive measurement of body parameters through photoplethysmography. This is a way to analyze blood flow in the vessels of the wrist using infrared waves. On the inside of the bracelets are photoresistors that read the resistance based on an analysis of the absorbed wavelength of light. The higher the pulse and blood flow rate, the less light energy will pass through the tissue. The resistor will receive a larger amount back. The technique is used to calculate the volumetric blood pulse, which occurs as a result of changes in the volume of blood fluid during contraction of the heart muscle. Photoplethysmography technologies monitor heart variability and heart rate.

Fitness trackers come with a variety of options. Basic functions - pedometer and calorie counter based on analysis of distance traveled. Models can count:

• pulse;
• arterial pressure;
• oxygen content in the bloodstream;
• quantity and quality of sleep.

Accessories are accompanied by software that is installed on the phone. Manufacturers produce applications for iOS and Android mobile systems. The devices measure blood flow pulsation with high accuracy. When measuring blood pressure, errors of up to 10 units are possible in the direction of increasing or decreasing the data.

Irina K .: A good thing for those who are engaged in sedentary work. If you sit too long, the bracelet will warn you in time about the need to take a walk or exercise. To do this, the model will give a signal. And it also works for quite a long time - at least compared to my previous fitness bracelet. The pressure measurements are so-so - I compared them with a medical tonometer, the difference is more than 20%.

Are blood pressure and pulse measured accurately?

The bracelet uses an optical method when measuring heart rate, which can allow an error of up to 10 units. The reasons for this are the density and color of the skin, hair on the arms and tattoos. To obtain the most reliable result, it is necessary to calibrate the device indicating gender, age, weight and accurate heart rate readings at rest. When measuring, you should fix the bracelet strap 2-3 cm from the bend of the hand, avoid sudden movements and conversations, and place your hand at heart level.

To determine pressure, special sensors on the device receive signals, process them and transmit them in numerical values ​​to the bracelet screen or through an application to the phone. Fitness bracelets are not medical devices, and therefore do not have requirements for displaying accurate results. To reduce the error, you should follow certain rules:

• Avoid active activities 30 minutes before measurement;
• The bracelet should be pressed tightly to the wrist;
• Maintain a calm state;
• Relax your hand with the device.

The level of error can be measured by correlating readings from a medical device.

Convenient trackers for pensioners

When choosing a reliable accessory for the elderly, remember that some devices are measured using conditional formulas based on the ratio of age, gender, and heart rate. This explains the large error of parameters during testing.

For people suffering from hypertension or heart disease, people with low visual acuity, and pensioners, it is important that the cardiac bracelet is characterized by high measurement accuracy, a large screen with clear display, and alerts about critical conditions.

Among the models offered by manufacturers for monitoring the health status of older people, the following accessories have proven themselves to be highly effective:

• Bizzaro F550. Equipped with several biometric highly sensitive sensors. The device accurately measures blood flow pulsation, blood pressure, and displays the data in the form of a cardiogram. The microprocessor in the capsule processes the obtained values ​​and converts them into an integral indicator. Information about the state of the body is received on the bracelet screen and in the application. The tracker is also equipped with a thermometer that measures the ambient temperature. The program on the smartphone is completely Russified, designed with the ability to fine-tune the user, including for reminders.

How to choose the best one?

In order to make the right choice in favor of one or another fitness bracelet, you first of all need to listen to yourself and understand what exactly you want to get from the device. Some may be only interested in the pedometer function, while others want to see a smart watch with all sorts of bells and whistles on their wrist. In any case, there is a suitable option for each of you.

Any fitness bracelet is based on a sensor that detects movements and is called an accelerometer. A special function converts sensor readings into kilometers and number of steps. Most models support synchronization with mobile devices and special applications that build graphs based on data received from trackers and keep track of your physical activity.

When purchasing, we recommend paying attention to the following parameters:

• functionality . All fitness trackers count the number of steps and kilometers traveled, many of them are also capable of measuring heart rate and blood pressure in real time. There are models that monitor your sleep, independently determining the time you go to bed and the time you start waking up. More expensive models are carefully equipped with various functions, including GPS, which allows you to build routes and track your location;
• display . If previously such devices did not have screens, and if they did, they cost a lot of money, but now absolutely all models have them. This is convenient, since all information is visible at once, even without synchronizing with a smartphone. When synchronizing, notifications about incoming calls and SMS appear on the display. The most expensive trackers have the ability to install screensavers, select watch faces and many other gadgets;
• autonomy . There are trackers that need to be recharged every 3-5 days, and there are those that last for a month of use;
• protection from moisture . Available in absolutely all trackers, but to varying degrees. For example, a bracelet with a protection degree of IP 65 perfectly copes with dust and water ingress from different sides, with a protection degree IP 67 it can easily withstand immersions to a depth of up to a meter, and with IP 68 you can not remove it even when diving to greater depths. You need to choose based on the degree of your activity;
• additional features . Some will remind you of a workout by vibration, others allow you to create a schedule of physical activity, others will also play the role of an alarm clock and wake you up with vibration;
• design . In most cases, bracelets do not have significant external differences from each other. Except that many manufacturing companies produce trackers with colored straps. Therefore, you can easily choose the one that best suits your style so that you can wear it all the time;
• price . It varies significantly on the market; there are models for 20 dollars and 200-300. Often, the latter contain the largest number of functions that you may not need at all. Take a closer look at inexpensive models; in most cases, they have a sufficient range of functions and are in no way inferior in quality;
• If we talk about the manufacturer, I would especially like to mention fitness trackers from Smart Band, Jet Sport, QS, GSMIN, ZDK, Smart Bracelet.

For more information about the selection criteria, watch the video:

If you are going to give someone a gift, then the most inexpensive models can be found and ordered on Aliexpress, but there may be problems with delivery and then you will have to wait for your parcel for several more months. If you don’t have this time, we can recommend ordering the goods in other online stores, for example:

• M Video.
• Citylink.
• DNS.
• Ozone.
• El Dorado.

The delivery of goods is carried out at special points, which are located in almost all cities. Delivery when ordering from these stores takes from 2 to 5 days.

How accurate are the readings?

The indicators obtained by the tonometer in the fitness bracelet coincide with the data of the medical tonometer by 50-80%. The error depends on the specific model and can range from 15% to 50%. The accuracy obtained from tonometer measurements on such gadgets is always lower than if the same indicators were measured using a medical device.

However, there is a huge plus that overshadows this small problem. With a tonometer located in the watch, it becomes possible to measure blood pressure and pulse without outside help.

Comparison of pressure and pulse indicators between the watch and a full-fledged tonometer:

Duration of deep sleep

During sleep, the correct alternation of phases and the duration of deep sleep are important. It is during the period of deep sleep that the nervous system and overall performance are restored. We can say that the body is going through renewal and reboot. Disturbing a person in deep sleep is the same as interrupting the firmware update process. The norm of deep and light sleep is exactly what allows you to completely rest.

To increase the deep sleep phase, you need complete comfort and absence of anxiety in this phase. A smart fitness bracelet can recognize sleep phases by heartbeat and control the process. Based on the bracelet and heart rate sensor data, you can determine what time you need to go to bed in your particular case. For example, you were worried or drank an extra cup of coffee in the evening. You see values ​​on the heart rate sensor that do not correspond to optimal sleep. Instead of tossing and turning restlessly in bed, trying to fall asleep, you can sit for half an hour, listen to calm music, until your heart rate returns to normal.

Where is it profitable to buy?

If you decide to buy this gadget as a gift for someone’s birthday or New Year, then it is better to think about this point in advance in order to purchase it at a favorable price. The most inexpensive fitness bracelets are sold on Aliexpress, but delivery from there can take up to 40 days.

If deadlines are already running out, then you can make a purchase in some online store, having first compared prices for the model you are interested in. We recommend such large retailers as:

• DNS (Technopoint);
• M Video;
• El Dorado;
• Online trade;
• Ozone.

These stores have pickup points in almost every city, and delivery times take only a few days.

Multifunctional sleep systems

Here is a real sleep analyzer.

Withings Aura smart sleep system

This is a whole complex, which is located next to the bed, aimed at improving the quality of sleep, costing $299.95. The elements of this system are a musical lamp, a mattress with a sensor that needs to be hidden under the sheet, and a software module. The device tracks your activity and correlates it with external factors that affect your sleep, such as room lighting, noise and even air quality.

In the evening, the room is lit with a pleasant orange (dusk-like) light and various lullabies are played. In the morning, blue light turns on, which stimulates an easy rise. Apparently, this affects the production of the hormone melatonin, which is responsible for the sleep-wake cycle.

Aura distinguishes three stages of sleep (not two!): in addition to deep and active stages of sleep, there is also the REM stage (rapid eye movement), during which we dream. There is a smart alarm function; Aura wakes up its owner with the sounds of nature rather than vibration. This is not the best idea, since many people would like to fall asleep to such sounds and not wake up. However, any track downloaded from the Internet can be used as an alarm clock.

A few words about Aura sleep sensors. This sleep tracker tracks body movement, breathing cycles and records your heart rate using the mattress. Add to this the statistics of external sensors, which include space lighting control, temperature control and a night voice recorder.

Nevertheless, Amazon democratically rates the gadget at 3. Users complain that the gadget is terribly difficult to regulate. You need to perform voodoo rituals to make it work, you can set it to sleep for 30 minutes, but it offers you functionality that is a little more than regular fitness bands. The gadget’s ability to calm and relax the user is questionable; mono monitors can also be found in cheaper gadgets. In general, read the reviews on the Amazon website and decide for yourself whether you need this system - a smart analyzer of your precious sleep.

Sense-Sleep Pill

This is another example of a specialized sleep monitoring system. It's still just a project, but it has already raised $2 million on Kickstarter. This tiny sensor is attached to the pillow using a clip, and monitors a person's activities during sleep (turning, talking while sleeping, etc.). The sensor consists of a 6-axis gyroscope that records the slightest movements of the user.

“Sense” monitors external stimuli such as humidity, air temperature and dust in the room, room lighting and the level of external noise. We were most impressed with the dust sensor. Manufacturers claim that the sensor can detect both small and large dust particles. The system can also detect if there is airborne pollen and report the results to its users. Overall, this is the most advanced gadget in terms of built-in sensors.

Striiv Fusion: 2 in 1 fitness tracker and watch (video)

Another interesting feature made by the developers is that your sleep is rated out of 100. There are guidelines for the rating that indicate what should be changed to improve the usefulness of your sleep. The product is priced attractively: you can pre-order Sense for $129. However, since the Sense-Sleep Pill is not yet on sale, all compliments towards the device are strictly theoretical.

Let's sum it up! Not all sleep trackers are worth their price. Mobile apps offer the fairest price-quality ratio, but their functionality is minimal. Fitness bands are more expensive, but they justify it with their versatility, which is why users trust most devices like the Fitbit Flex. Find out what trackers have appeared in the new season from the article: “Smart” bracelets. New items of the year.

This is a fashion trend these days, which is why these items are selling. We would like to present to your attention several interesting devices:

• Sleep Shepherd Hat ($149.99) was designed for those who have trouble sleeping. Manufacturers promise that the device will help you slow down your brain activity so you can relax and fall asleep. Users were skeptical at first, but the Sleep Shepherd hat actually helped them fall asleep.

• If you don't want to wear something on your head, then there is the DREAMATE SLEEP AID for $54.94. It relaxes your muscles and helps you fall asleep faster, especially if you wear it for 30 minutes before bed... The bracelet is tested by Dreamate Sleep Aid users.

• NightWave Assistant, a small device that normalizes your breathing and calms you with soft light, costs $50.33.

• For those who take sleep really seriously, there's the Zeo Personal Sleep Manager for $549.99. This system should monitor your sleep and make recommendations on what should be done to improve the quality of your sleep and get rid of the negative factors that impair it.

If you still can't decide which sleep tracker you should buy, read the customer reviews on Amazon.

   WHAT?! BEHIND?! RAVE?! Quote: “If your alarm goes off while you are in deep sleep, you are unlikely to wake up at the count of three. But if you are in the active sleep stage, you will wake up rested and energetic.” As I understand it, “deep” sleep here refers to the slow-wave sleep phase, and “active” sleep refers to the REM sleep phase. So, during the slow-wave sleep phase it is much easier to wake up, but during the REM sleep phase it is, on the contrary, more difficult. And all sleep trackers are designed specifically for waking up during the slow-wave sleep phase. Do not mislead people.

   I completely agree, in the REM sleep phase the brain approaches the beta rhythm in wave activity and it is much more difficult to wake up during this period than in the slow-wave sleep stage. Moreover, some scientists believe that interruption of REM sleep causes more severe mental disorders compared to disorders of slow-wave sleep. Some of the interrupted REM sleep must be replenished in subsequent cycles. It is also assumed that REM sleep provides the functions of psychological protection, information processing, and its exchange between consciousness and subconsciousness.

   Third stage. Slow sleep. Stage 3 is classified if delta oscillations (2 Hz) are less than 50% and stage 4 if delta is more than 50%. Stage 4 of slow-wave sleep, deep sleep. The EEG is highlighted with a red frame. Fourth stage. The deepest slow-wave delta sleep. Delta oscillations (2 Hz) predominate. The third and fourth stages are often combined under the name delta sleep. At this time, it is very difficult to wake a person; 80% of dreams occur, and it is at this stage that attacks of sleepwalking, night terrors, sleep talking and enuresis in children are possible. However, the person remembers almost none of this.
