Four ordinary things
Sleep
A regular bedtime and enough hours help many adults feel more rested. The sleep calculator only lines up 90-minute cycles with a wake-up time. It cannot tell you why you are tired.

Water
Thirst, meals, and ordinary drinks cover much of a normal day. The water guide is a rough figure from weight and activity. It is not a rule, and a fluid limit from a clinician comes first.

A walk
A walk you can hold a conversation through is ordinary movement. It is not a treatment and not a training plan. Stop if something hurts, and rest when you have been told to.

Reading a study
One paper is a clue, not a conclusion. Check who was studied, how many people, and whether others have repeated the work. A claim that something prevents a disease usually goes past what a single study showed.

Simple calculators
These run in your browser. They are rough figures, not a checkup.
