In a nutshell, the explanation of the quantified self from Wikipedia: the quantified self refers both to the cultural phenomenon of self-tracking with technology and to a community of users and makers of self-tracking tools who share an interest in “self-knowledge through numbers.” Quantified Self practices overlap with the practice of lifelogging and other trends that incorporate technology and data acquisition into daily life, often with the goal of improving physical, mental, and/or emotional performance. The widespread adoption in recent years of wearable fitness and sleep trackers such as the Fitbit or the Apple Watch, combined with the increased presence of Internet of Things in healthcare and in exercise equipment, have made self-tracking accessible to a large segment of the population.

Other terms for using self-tracking data to improve daily functioning are self-tracking, auto-analytics, body hacking, self-quantifying, self- surveillance, and personal informatics.

Because what you can’t measure, you can’t change

I started tracking all kinds of personal metrics on recently, so yes, maybe I’m part of this movement. I also got inspired by this article. I was tested for sleep apnea two weeks ago (having my results discussed next week) but in the meantime I’m using the Sleep Cycle app to record my snoring. My girlfriend told me the snoring became less after my CABG and switching to a whole-foods, plant-based diet. I’m planning to monitor my snoring myself and see if there are some life hacks to reduce or even reverse the snoring. I’ll keep you posted!
