Smartwatch Benefits

Smartwatches are not just a timepiece like traditional watches. It is packed with robust sensors and technology that can track and monitor your overall fitness, activities and much more. 

Latest smartwatches have given more emphasis on health tracking features. They come with advanced health tracking features such as Heart rate monitoring, ECG tracking, Blood oxygen level monitoring, sleep tracking, stress tracking and much more. 

If you are in need for a smartwatch with advanced health-tracking features, then you can go for the latest smartwatches like Apple Watch Series 6, Samsung Galaxy Watch3, Apple Watch Series 5, Samsung Galaxy Watch Active2 or Fitbit Sense. All these smartwatches come with an FDA Approved ECG tracking features in addition to many other health-tracking features. 

Heart Rate Monitoring

Heart Rate monitoring

A smartwatch can monitor your heart rate right from your wrist. Smartwatches are equipped with optical sensors to monitor your heart rate 24/7. Premium smartwatches like Apple Watch use a technology called photoplethysmography to monitor a persons heart rate. 

Modern smartwatches have gone beyond just heart rate monitoring. These devices can alert you if your resting heart rate goes beyond or below the normal range. It can even alert emergency department in case of an abnormal heart rate. 

Identification of an abnormal heart rate can save peoples lives by allowing them to seek medical help at the earliest. So if you have a smartwatch and it alerts you with an abnormal resting heart rate, you should not hesitate to seek immediate medical help. 

ECG Tracking Feature

ECG Monitoring

ECG tracking is the most advanced cardiac health tracking feature available in a smartwatch. Even though a smartwatch with ECG can not be considered as medical equipment, it can detect irregular heart rate, irregular heart rhythm and Atrial fibrillation. 

You must seek immediate medical help if your smartwatch alerts you with an irregular heart rate or atrial fibrillation even if you do not feel any discomfort or uneasiness.

It can measure your ECG right from your wrist anywhere anytime in 30 seconds. Most of the ECG tracking smartwatches allows you to share your ECG report with your doctor so that he can have a closer look into heart health. 

If you are looking for a smartwatch with ECG, then you can check our latest list of the best FDA Approved smartwatch with ECG. A smartwatch that tracks ECG cost you more money than other smartwatches that comes without an ECG app. 

However, if you want to have a closer look at your cardiac health, then an ECG Smartwatch is worth buying. 

Blood Pressure Monitoring

Blood pressure monitoring

Blood pressure monitoring is another great feature available in smartwatches and fitness trackers. As blood pressure monitoring is a complex process, only a limited number of smartwatch makers have succeeded in integrating blood pressure monitoring technology into smartwatches. 

Even Fitbit does not have a smartwatch that monitors blood pressure monitor. We hope that soon they will come up with a smartwatch that tracks blood pressure. But there is no official announcement from Fitbit about Fitbit blood pressure monitoring smartwatch

Samsung Galaxy Watch3, Samsung Galaxy Watch Active2 and Omron Blood pressure smartwatch are the examples of best smartwatches with blood pressure monitor. 

The Omron Blood pressure smartwatch is the first smartwatch approved by the FDA for wrist-based blood pressure monitoring. 

Blood Oxygen Level Monitoring

Blood Oxygen Level Monitoring

SpO2 or Blood oxygen level monitoring is an advanced feature in smartwatches and fitness trackers. Smartwatches use a blood oxygen sensor to calculate the blood oxygen level in your body. 

Besides, measuring SpO2 can help you better understand your sleep pattern and apnea.  

If you are a hiker, then a smartwatch with SpO2 feature will be very useful when you clip high altitudes.

In a nutshell, a smartwatch with SpO2 allows you to understand how well your body absorbs oxygen. A SpO2 level of more than 95% is considered regular reading. 

Body Temperature

Women with Fever

Today wearable tech devices such as smartwatches and fitness trackers are capable of measuring your skin temperature. Like Blood pressure monitoring, temperature tracking feature is also not available in many smartwatches because of its complexity and a higher chance of error. 

Fitbit Sense and Garmin devices are some of the most reliable smartwatches that track your body temperature accurately. 

When we say body temperature, it actually means that the core temperature rather than skin temperature. 

With said that, the temperature measured by a smartwatch might not be accurate as it takes just skin temperature rather than the core temperature. External factors like cold or hot can influence skin temperature but not the core temperature. 

However, a series of temperature taken by your smartwatch can give you an idea about your body temperature trend, especially if you are suffering from fever or infection. 

In hospital setup, core temperature is measured by using an oral, axially or rectal thermometer. 

Respiration

Respiratory rate is another crucial vital signs along with heart rate, SpO2, B.P and temperature. The resting normal respiratory rate is 16-20 breaths per minute, and it goes up to 40-50 breaths per minutes during physical activities. A smartwatch uses various sensors and analysis methods to track your respiratory rate. 

7. Calorie Tracking

Calorie tracking

One of the essential features of a smartwatch is calorie tracking. Calorie burn is a calculated value derived from various factors such as your age, sex, and activity. So you must give accurate data while setting up your fitness app or smartwatch.

If you are a weight watcher and looking to gain or lose weight, then you should closely monitor your calorie intake and calorie burn. For example, if your goal is to lose weight, then your net calorie intake must be a minus value. This means that you must burn more calories than you eat and vice versa, in case, to gain weight. 

Not sure how much calories should I eat each day? You can check this excellent article on calorie intake per day

If you pair your smartwatch with a calorie tracking app like MyFitnesspal, then you can have a closer and accurate data of your calorie intake and calories burned. While your smartwatch tracks your calorie burn, your calorie app monitors your calorie intake. 

Myfitnesspal is a fantastic app I use to monitor my calorie intake and calorie burn. If you are looking for a smartwatch or fitness tracker compatible with MyFitnesspal, then you can have a look into my most fantastic pick of smartwatch and fitness trackers compatible with MyFitnesspal

Stress Tracking

Stress Tracking

Stress is a common issue faced by the majority of people around the globe because of modern lifestyle. A smartwatch can track your stress level by monitoring various factors such as heart rate, blood oxygen level, respiratory rate, etc. 

If your smartwatch alerts you for stress, then you should go for a short walk or have can have a cup of coffee.

Sleep Tracking

Sleep is essential for your overall health and wellness. To maintain a healthy body and mind, you must have a good sleep. An adult requires to sleep at least 8 to 9 hours per day for optimal health. Sleep Deprivation may lead to many physiological and psychological diseases. 

A smartwatch can track your sleep stages right from your wrist and give you sleep quality score after assessing various parameters such as heart rate, blood oxygen level, movements while sleep, etc. Based on this sleep quality score, many smartwatches can also give some suggestions to improve the quality of your sleep. 

Fall Detection

Fall detection

Fall detection is a life-saving feature available only in premium smartwatches like Apple, Samsung and Garmin. If it detects a hard fall, then these devices activate an Emergency alert. If you do not deactivate emergency alert within a few seconds, the smartwatch will contact the Emergency department with your current location. 

This helps emergency responders to reach your location without wasting time. 

Fall detection feature has also saved many people from death. In an incident in Washington, a man’s life saved by Apple Watch after he falls from his bicycle. You can read this news report in detail here. This incident later shared by his son on Facebook as well.

Yoga is another popular indoor activity performed by many, especially during COVID-19. Many smartwatches and fitness trackers struggle to record Yoga because of the relatively slow movements involved in Yoga practice. 

This makes it very hard for a smartwatch to track your yoga activities. Because of this reason, I have written an in-depth article on the best smartwatches for Yoga.

Make Calls and Sent SMS

Best standalone smartwatches

A standalone smartwatch with cellular connectivity can work like a smartphone. Usually, a smartwatch works by connecting it your smartphone for connectivity. 

But in case of a standalone smartwatch, like smartphones, it can connect to a cellular network provider by bypassing smartphone. As a result, you can do most of the stuff that you do with your smartphone. 

A smartwatch with LTE allows you to make phone calls and use internet-based apps right from your smartwatch even when you are away from your smartphone. 

Smartphone Notifications on your wrist

Notifications

A smartwatch can display your smartphone notifications so that you can stay updated with latest phone notifications from Twitter, Facebook, WhatsApp, etc. even without grabbing your smartphone. It is beneficial when you work or drive a car/bike. 

If you are using a smartwatch without LTE connectivity, then you need to be connected with your smartphone to receive notifications on your watch.

Some smartwatches come with microphones and a loudspeaker so that you can speak right from your smartwatch. Also, some smartwatches allow you to relay to a text message from your smartwatch.

Find your Phone

Find your phone is another great feature that is very useful if you forget your smartphone somewhere in the home. In this case, when you press a button on your smartwatch, your smartphone starts to vibrate and alert so that you can easily find your smartphone. 

You can use find my phone feature in Samsung Galaxy Smartwatch even when your smartphone is away from Bluetooth range. 

Navigation

Smartwatches and Fitness Trackers are continuously monitoring your important vital signs such as heart rate, blood oxygen level, temperature, respiration, activities and sleep. Now researchers are trying to use smartwatches for the early identification of COVID-19 diseases. 

From the smartwatch data of COVID-19 patients, the researchers have found that there was significant variation in vital signs, activity and sleep pattern before the onset of the signs and symptoms. 

However, as of now, no smartwatch makers claims that their devices are capable of early detection of COVID-19 or other flues like infections. 

Do smartwatch detects a heart attack?

A smartwatch can not detect a heart attack. However, a smartwatch with ECG App and heart rate monitor can detect irregular heart rate and atrial fibrillation. 

Atrial Fibrillation is a severe medical condition which needs immediate medical help. If not treated on time, it can lead to a heart attack or stroke. 

Payments

Contactless Payments

Smartwatches allow you to pay at a shop right from your smartwatch through contactless payments. Different smartwatches offer different payment methods such as Fitbit Pay, Samsung Pay, Garmin Pay and Google Pay. Smartwatches operated on Wear OS use Google Pay as their mode of payment.

If your smartwatch allows you contactless payments, then you go for a walk and have a coffe or snack even without your smartphone or wallet with you.

Other features

In addition to that, smartwatches offer many other features such as reminder, alarm clock, stop clock and much more. All these smart features together make a smartwatch smarter than a traditional watch that uses for timekeeping. 

Disadvantages of a smartwatch

Disadvantages of a smartwatch

We have already discussed smartwatch benefits. Now let us have a look into the disadvantages of a smartwatch. 

Expensive

A smartwatch is more expensive than a regular timepiece. Here I am not talking about luxury watches like Rolex. If you do not want to spend more money on an expensive smartwatch, then you can go for cheap smartwatches under 50 or 100. 

Poor battery Life

Generally, smartwatches have short battery life. Even Apple watch offers 18 to 20 hours of battery life only. The battery may drain even faster if you use features such as GPS, music streaming, etc. 

With that said, there are many self-charging, and solar charging smartwatches are available in the market. 

Need a smartwatch Nearby

A smartwatch needs a smartphone nearby to use some features, especially if you use a smartwatch without LTE connectivity. Even an LTE smartwatch requires a smartphone for initial set up.

In a nutshell, you can not use a smartwatch without a smartphone.

Compatibility

You can not use or enjoy some features if you are using a smartwatch which is not compatible with your smartphone. For example, you can not use an Apple watch along with an android smartphone. 

Likewise, if you use a Fitbit or Samsung Watch along with Apple Phone, then you will be restricted from using some features. 

So you must always make sure that the smartphone that you own must be compatible with the smartwatch that you are planning to buy. 

5. Waterproof Damage

Once the waterproof sealing of smartwatch damaged, then it can not be restored. So you should not expose your smartwatch corrosive liquids like soap, detergent, spirit, etc. 

  1. How does a smartwatch work?

    A smartwatch is a tiny wearable computer equipped with multiple sensors and algorithms to detect various body metrics and activities. 

    With the help of these sensors, it can track your various activities like steps, running, swimming, biking and much more. Also, these tiny devices can track and record various body metrics such as heart rate, blood oxygen level, ECG; Calorie burned, etc.

    To start using the smartwatch, you need to pair it with your smartphone after downloading the companion app. Once you paired your smartwatch and smartphone, it starts to track your activities and body metrics with the help of advanced sensors and algorithms. 

  2. Do smartwatch emits radiation?

    Like other wireless devices, a smartwatch also uses Wi-Fi, Bluetooth and cellular connectivity. So a smartwatch also emits EMF radiation like your smartphone or wireless earbuds. 
    To sale a wireless gadget in the USA, a smartwatch must get preapproval from the FCC( Federal Communications Commission). The FCC ensures that the devices are emitting the limited RF Radiations only. 
    If you check the package of wireless equipment, then you can see an FCC ID on the package. This means that that device is emitting radiations within the acceptable limit. 

Conclusion

In a nutshell, a smartwatch is a tiny wearable computer that you can wear on your wrist to monitor your various activities along with health metrics. Also, it makes your life easier as it has many smart features and functionalities. 

I personally like smartwatches because of these features and functionalities mentioned above. I hope that this article helps you in understanding the advantages and disadvantages of the smartwatch.
