I've been fortunate to grow up in the '90s. Anyone reading who also grew up during this decade knows that we witnessed the start of the internet and technology boom to what it is today. Remember landlines and dial-up to access the WorldWideWeb. No WIFI back then and today, there's an app for everything. There's been an ongoing trend of smartwatches and tracking devices. I for sure fell for this "trend" for many reasons, seeing who is calling or texting you displayed on a watch face, knowing what the weather temperature is outside the stopwatch and timer, and even knowing your heart rate! This was awesome that it was all shown on a LED watch face. Yes, this is the apple watch that I currently use and wear daily. Okay, I'll admit I also have another tracking device which is the Whoop strap. I know you're probably thinking I'm crazy, but I believe to make serious health or fitness changes, some of this information helps see what is working and what is not. I use my Whoop strap for more health and fitness habit and performance tracking. Especially the sleep tracking technology that is used to inform you how you slept. HUGE benefits with this information as getting restful sleep are by far one of the most important things you can do for your mind, body, and health. It also gives you weekly and monthly performance summaries of such health measures as your strain (exertion), recovery (response to strain), and sleep performance. I use this info to guide my daily habits.
Understanding that it can lead to getting obsessed with all this data and information, it's important to note that tracking devices are a helpful tool to guide your daily habits and performance. Using tracking devices do just that, giving you a real-time reading of multiple health measures to guide you to make healthier decisions and/or actions. So back to the question of are they worth it? Yes, I believe they are if you truly want to make a change you need to know where you currently are at in terms of the internal body systems (cardiovascular system, and central nervous system). Of course there this isn't 100% accurate, but it's still useful information, again, to make a habit change. Especially if currently you're experiencing a health issue or just want to keep tabs on how to maintain your optimal fitness and overall wellness.
