…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.
Difference is: You will very likely feel thirsty - these “water challenges”/new year resolutions where people are at times literally drinking more water even though they feel already borderline nauseated are insane.
And in terms of electrolytes: It’s mixed bag: First and foremost we generally oversatisfy our demand with our diets these days and unless you work very unsteady patterns it’s unlikely an issue. But: On the other hand electrolyte issues are a fucking mixed bag and, especially in healthy muscular people, tend to stay “good” for a long time until,well, they escalate hard and fast. Literally had a colleague of you fall of a roof due to tachycardia caused by electrolyte issues. (Which every paramedic student around here now hates him unknowingly for because it’s an all time favorite for exams now)
So…maybe occasionally eat some nuts, bananas or similar and a bit of cheese after a hard day. Even dark chocolate isn’t that bad in that regard.
