Funny how Europeans and others aren't constantly "hydrating" (in fact, they tell me they think Americans are silly for carrying water bottles around), yet they never suffer any effects of dehydration. (Most European meals are served with only single-digit ounces of liquid.) You really don't need to drink very much, and in fact drinking large quantities can produce some bad effects by demineralizing the body (magnesium in particular, but many others too), especially over the long term...

I monitor my urine color and how I feel. If I feel bad I’ll grab a glass of water or even buy a plastic bottle, but that happens maybe once a year.

I really think that people aren’t that fragile and the bottled water industry has done an excellent job of making people think they need to constantly hydrate in order to not have a heat stroke.

Imo it’s enough to just pay attention to yourself and how you feel.
