That's an advantage - it means you're not sitting e.g. at a computer monitor and keyboard for too long. Getting up twice an hour (to pee or not) greatly reduces the potential for ergonomic harm that desk jobs - especially computer use -are known for.
If you're peeing that much then evidently your body is not using all that water you're consuming. Either it's more than you need, or you're lacking in electrolytes and should increase electrolyte intake alongside the water.
Parent is correct. NHS sources say upto 7 times during the day is normal and "Every 3 to 4 hours is considered healthy. Going every 1 to 2 hours usually means you either have an overactive bladder or are drinking too much at once."
Saying every 30 minutes is normal is just the same as advocating drinking too much water
I’m not arguing that 100% of water consumed can be retained, just that peeing every 30 minutes means you have an unnecessarily large surplus. This is simply a truth.
