> How many of us are just chronically tired? That is a tough question. Activity, it seems, has a habit of begetting activity. Such that the answer may not be, "you need better sleeping habits," but it could be more that, "you need better activity habits." Noticing things is also a dangerous place to be in. A lot of what your body does while asleep is based on expectations as much as it is anything else. Learned expectations, to be specific. Most people know the "you wake up before the alarm goes off" idea. That is strong enough that it will work for changes in the alarm time. What does that mean? It may be that your body learned a cue to start something for your sleep. So, for you, you now need to turn on your blue light filter; even if that may, in fact, not be actively doing anything.
