…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 doesn’t work for me and multiple people I know. I drink way too much because of that and they sometimes don’t drink anything for over 24h
I’m no expert so take what I say with a grain of salt.
It’s not a perfect system for the same reason some people over-eat and some don’t eat at all. Your lifestyle could also affect it.
If you are frequently thirsty and no amount of water is quenching your thirst, you might not have enough electrolytes to retain the water causing you to always be thirsty. Apart from gatorade or pedialyte, coconut water is also high in electrolytes…or maybe you have diabetes.
Again, I’m no doctor and I may be talking out my ass and obviously I don’t know you or your lifestyle. Just what I remember reading when I had issues drinking water.
I don’t drink because im thirsty. I drink because I made it a habit, otherwise I forget.
