My story today: I've been debating getting a smart watch for some time now. Well, I had one, but it only lasted about a day and I couldn't be bothered to wear it anymore.
I've now bought a hybrid smartwatch which lasts over a month. As a bit of an analytics geek, I like tracking stuff like exercise, sleep, body weight, etc. I also like the idea of being able to see trends over time truth historical data.
And my watch told me that I don't really sleep deeply. Which is a factor in restoring your energy for the next day. Factors that affect this are going to bed late and drinking too close to bedtime. So I'm on a sort of experiment to see if I can get back some deep sleep by not drinking for a while, or at least be more mindful of it on weekdays. I started this last Sunday and I'm still doing okay, even though I had a bit of a tough day at work yesterday and I felt like having a drink but I didn't.
I really hope at some point I will wake up refreshed and my watch will tell me the same. If it doesn't, I feel I might as well have a lil drink each night...
And before anyone tries to tell me that my watch isn't showing me empirical truths and it's just guessing based on heart rate and movement metrics, I know. I just need the confirmation bias at this point.
