…because the shape of the water bottle isn’t uniform either. Part of my new year’s resolution is to drink 4 liters of water per day, so I spend a lot of time looking at those lines. Edit: 4 liters is a lot, but appropriate for my size and activity level. Without conscious consideration I don’t drink enough water. It looks blue because the bottle is blue.

    That was NOT a scientific recommendation. If you’re not getting sample tested, most doctors would first direct you to urine color and skin snappiness

    What the source says:

    Studies have produced varying recommendations over the years. But your individual water needs depend on many factors, including your health, how active you are and where you live.
    …
    No single formula fits everyone. …
    Most healthy people can stay hydrated by drinking water and other fluids whenever they feel thirsty.
    …
    Your fluid intake is probably adequate if:
    -You rarely feel thirsty
    -Your urine is colorless or light yellow

      The mayoclinic page I linked said the 3.7 liters recommendation comes from the U.S. National Academies of Sciences, Engineering, and Medicine. But yeah, even if it’s 3 liters after you knock off the 20% you get from food intake, that’s a lot of water.

        Was not a recommendation, but an observation on how much people seem to get. National academy of medicine also recommends drink when you’re thirsty.
