Heart attack is the leading cause of death for many people according to healthday.com, therefore to have a device that able to inform your heart condition is very important. But, how far actually this device can help you? This powerful device not only can inform you about your heart rate, but also able to detect various health problem. In a simple word, heart rate is how many times your heart beats for a minute, the number is can be affected by numerous factors.
What Is A Normal Healthy Heart Rate
No matter if you’re an athlete or not, having knowledge about a healthy heart rate can be very helpful if you want to accurately monitor your fitness level and even spot various health problems. Simply put, heart rate is the number of times your heart beats in 60 seconds and it varies from one individual to another. By knowing your own normal heart rate, you can easily gauge if you’re in a good health condition or not.
One thing to remember about heart rate is that as you age, your pulse is going to continuously change and sometimes, it may signal a heart or other type of condition that requires medical attention – any concerns whatsoever then you must seek professional medical advice.
What Is Heart Rate
Heart rate is one of your most important vital signs and as previously iterated, it represents the number of times your heart beats in 1 minute. Heart rate though can be affected by multiple factors and it varies throughout the day. Besides your regular heart rate, you also have a resting heart rate, which represents the pulse you have when you do nothing at all. Once you start doing physical activities, your heart rate is going to go up in order to deliver more energy and O2 to your system.
But it’s not only physical activity that can increase your heart rate. Adrenaline, which is a powerful hormone, has a great influence on your pulse. That is why when you feel scared, your heart beat increases very fast. It signals that your body is preparing to use more energy and O2 in the fight or flight reaction.
How do Smart Watches measure the heart beat on the wrist?
The heart rate monitor is based on a difficult to pronounce technology called photoplethysmography, but it basically comes down to using green LED lights paired with light‑sensitive photodiodes to illuminate your skin and measures changes in light absorption.
This lets the device detect the amount of blood flowing through your wrist at any given moment. Because blood is red, it reflects red light and absorbs green light.
“When your heart beats, the blood flow in your wrist — and the green light absorption — is greater. Between beats, it’s less,”.
The sensor are designed to compensate for low signal levels by increasing both LED brightness and sampling rate. That’s why the heart rate sensor on the back of the device flashes its LED lights hundreds of times per second, helping the device calculate heart rates precisely.
But when it measures your heart rate every ten minutes, the Watch switches to using infrared light. And if it fails to provide an adequate reading while using the infrared light, the device switches back to the green LEDs.
In order for the sensor to work as advertised, the Watch must be close to your skin. The company advises tightening the band in case the sensors aren’t reading your heart rate accurately.
All in all, the heart rate sensor in the Watch is a great feature, especially if you’re something of a fitness buff. It checks your heart rate during workouts for an at-a-glance overview of both the intensity level and the heart rate change over time.
Measuring Heart Rate Using Smartwatch
If you want to get a really accurate heart rate measurement, using a smartwatch monitor is going to give you the best results. Most heart rate monitors these days not only provide you with an accurate measurement of your pulse, but they can also store the values so they can be later accessed or can help you track your activities like a fitness band as well as give you SMS and email notifications like a phone.
As you can see, there are many factors that affect heart rate and if you notice you have a consistently high or low pulse, it’s best you get in touch with your doctor right away. By doing so, you’ll be able to see what condition affects your heart and consider the right treatment to keep it under control.
This is crucial, as having continuous readouts of one’s heart beat in the Health app is indispensable when correlating your workouts and heart rates. In addition to your heart rate reading, the Watch collects other data to provide estimate on calories burned.
Aside from the heart rate sensor itself, it may tap into other sensors depending on your activity. In one example, running indoors prompts the Watch to use its built-in accelerometer.
But go cycling outdoors and the Watch starts using the GPS in your Phone, if available, to track your activity with great precision in order to provide as accurate estimate on calories burned as possible.the Watch learns about your stride enough over time to start accurately track workouts without an Phone.
