Keeping track of our health is an essential part of leading a healthy lifestyle. In the past, monitoring our heart rate required specialized equipment and visits to a healthcare professional. However, with advancements in technology, our Android phones can now monitor our heart rate using the LED flash and camera. In this article, we'll explore how this technology works and how to use it to monitor your heart rate.
How does it work?
When your heart beats, it pumps blood through your arteries, causing them to expand and contract. This change in blood volume causes a subtle change in skin color that is detectable by your phone's camera. The LED flash illuminates your finger, and the camera captures the changes in skin color caused by your heartbeat. A specialized app then analyzes the data captured by the camera and calculates your heart rate.
What do you need?
All you need is an Android smartphone, a camera app that supports heart rate monitoring, and a quiet environment. There are several free apps available on the Google Play Store that can help you monitor your heart rate using your phone's camera and LED flash.
How to use it?
First, download a heart rate monitoring app like Instant Heart Rate, Runtastic Heart Rate, or Cardiograph. Once downloaded, open the app and place your index finger over the camera lens and LED flash on the back of your phone. The app will then begin to capture data and analyze it to calculate your heart rate. It's essential to keep your finger steady and not move it during the measurement.
Some apps require you to hold your phone steady and place it on a flat surface. In contrast, others require you to hold the phone and press your finger against the camera and LED flash. Follow the app's instructions for accurate results.
Things to remember
It's crucial to note that heart rate monitoring apps using your phone's LED flash and camera are not a substitute for professional medical advice. If you have any concerns about your heart health or have a pre-existing medical condition, consult with a doctor before using this technology.
Additionally, this technology is not always 100% accurate, and factors like lighting conditions, skin color, and age can affect the results. It's best to use these apps as a reference tool and not as a definitive diagnosis.
Conclusion
Using your Android phone to monitor your heart rate using the LED flash and camera is an excellent way to keep track of your health. It's a convenient and easy-to-use tool that provides valuable insights into your heart health. However, remember that it's essential to consult with a doctor for any significant concerns about your health. With this technology, you can be more proactive about your health and make informed decisions to improve your well-being.
