Action: keep the bottle in view.

Heat days
In hot weather, add ORS or lemon-salt water sometimes.
Action: limit sweet drinks.

Is this exact for everyone?
No—hydration needs vary by climate, sweat, diet, and health conditions.
What about tea/coffee?
They count as fluids but may not hydrate as well as water. Balance with plain water.
Any India-specific tip?
In hot मौसम, add ORS/lemon-salt water occasionally if you sweat a lot (avoid if medically restricted).
