…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.
Yeah, I never understood these arbitrary water volume challenges. Drink when you’re thirsty. If you’re you are worried, just take some extra drinks each time. Most hydration issues can probably be solved by drinking water instead of anything else… like whatever is in this container

3.7 liters (~16 cups) is the scientific recommendation (source), but you’re supposed deduct from that number what you’re getting from food, which is why everyone is freaking out about 4 liters of straight water.
That’s cause I only eat completely dehydrated food. It makes tracking my fluid intake much easier.
That doesn’t sound right at all, as obviously it would depend on the size of your body. The recommendation I’ve heard is 30-40 millilitres per kilogram of body weight, so by that to need 4 litres per day you’d have to weigh 115 kilograms.
I’m not entirely convinced by body weight either though, because e.g. perspiration is affected more by the body’s surface area than mass, and surface area does not grow linearly with body mass. Water loss via respiration is probably the same regardless of your size, because your lungs are still the same size. Cellular metabolism, I imagine, doesn’t scale linearly either because as you get bigger you don’t get more cells, the existing ones just get bigger, but I know very little about this.
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:
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.
As someone with ADHD, I often don’t realize I’m thirsty until I have a headache and am about to pass out. Having an even arbitrary water goal forces me to do the math every once in a while and go “oh, I should probably drink something today”
You’re supposed to drink water until your urine is clear-ish, I think. I hydrate until my hookers aren’t yellow.
