I find it fascinating how much information we can now gather about our bodies. We have rings that track our sleep, watches that measure our heart rate, and devices that show how our blood sugar responds to different foods. After 28 years working in holistic wellness, I love seeing technology give us new ways to understand ourselves. But I do wonder whether all this information is always helping us.
Imagine waking up feeling wonderful after a great night's sleep, only to check your watch and discover that your sleep score was terrible. Suddenly, you're questioning how well you actually rested. It's interesting how quickly a number can change the way we feel about our own experience.
Research is showing us that these devices have limitations. A 2025 review of 24 studies found that consumer sleep trackers don't always match the results of clinical sleep testing. And while continuous glucose monitors can be extremely valuable for people managing diabetes, research into their benefits for otherwise healthy people is still developing.
I believe there's tremendous value in understanding our bodies, but I also think we need to be careful about turning every natural change into something that needs fixing. Our health is influenced by so much more than what appears on a screen, including our relationships, daily habits, environment, and the simple pleasure we get from living our lives.
I'm excited about the future of longevity research and the technology that comes with it. I just hope we remember that these tools are meant to help us understand our health, not take away our ability to recognize when we feel well.
