Sleep
Sleep is more than the number shown by an app. Time available for sleep, how you feel during the day, routine, environment, and possible health problems belong in the same conversation. A tracker or supplement addresses only part of it.

Start with the routine you can observe
A consistent sleep schedule and a suitable sleeping environment are basic reference points. Record what you changed instead of attributing every good or bad night to a new product. Read the core sleep guide before interpreting wearable scores or trying to compare supplements.
Know when the question is clinical
Ongoing sleep problems or daytime impairment should not be diagnosed through a score or search result. General habits and mindfulness education can be useful context, but they are not individualized care. A magnesium form name does not resolve the underlying sleep question.
