Wearable Fitness Trackers and Heart Disease

JAMA Cardiol. 2016;1(2):239. doi:10.1001/jamacardio.2016.0354

Fitness or activity trackers are devices with special sensors that can monitor your movement. Often referred to as “wearables,” these devices are typically worn around the wrist as a bracelet or embedded in a mobile phone or wristwatch. They can measure footsteps taken, distance traveled, type of movement (walk, run, or jog), and quality and duration of sleep. Some wearables have additional sensors to monitor heart rate, blood pressure, blood oxygen levels, and perspiration. Data from wearables can be transferred to a smartphone, computer, database, or website. Connected smartphones and wearables can alarm or vibrate to encourage behaviors, such as exercise or sleep. As wearable technology matures, these devices will likely cost less, and it may become easier to share data from them with your health care professional, clinic, or hospital.

    Wearable Fitness Trackers must be standarized , must be user-friendly and must be eco-friendly.

    This is good to read an article on 'Wearable Fitness Trackers and Heart Disease '.
    It is essential for a wearable fitness trackers to have a right fit in users, and users should set a goal and remain get motivated during use.
    There may be a risk of radio waves exposure among users also it’s easy to tamper with data collected by wearable fitness trackers, hence health data of users are at risk.
    Although regulatory hurdles are present, there should be enough evidence regarding safety, hence trials are needed in large population to get more data.
    fitness trackers must be standarized, must be user-friendly and must be eco-friendly.
