How much does one like?

Wouldn’t it depend on how much you are sweating and peeing?

Too much and you might explode.

Google “overhydration.” It’s late and I’m going to bed.

If you drink too much water you could put yourself at risk for water poisoning as drinking too much of it throws off your electrolyte balance which is really dangerous and can actually lead to death (that’s why athletes drink Gatorade and the likes to stay hydrated instead of just plain water). I don’t think there’s a limit per se as to how much water one can drink, just make sure you keep it balanced with your food intake, which is what helps replenish your electrolytes.

Depends how much you are sweating. It is dangerous to chug a lug a bunch of water at once. Your tissues can get flooded and it can be a serious emergency, you can die. Too much at once the kidneys cannot eliminate the fluid fast enough. I know two people by way of son of a friend of my dad, and son of a friend of friend who did this. One wound up hospitalized, but wound up fine, the other died.

If your pee is clear, basically like water, you are sufficiently hydrated, maybe even more liquid consumption then you need. If it is very very yellow, then probably you need more water.

If you are thirsty all the time and not exercising or sweating a lot, then you should check yourself for diabetes.

The big thing is not a lot of water at once, so your system can absorb the water and keep your electrolytes in balance.

I know from experience that you can drink at least 1 gallon for every 100lbs of body weight without it causing issues. I did that during a weight loss/physical fitness challenge with my personal trainer. At that time I was 260lbs so that’s 2.6 gallons of water per day.

Usually too much of anything is “bad” for you.

I spent yesterday in 87˚ with high humidity. I oozed sweat all day long and drank bottle after bottle of water. I didn’t pay attention to the amount; the body was doing its own calculations…supply and demand.

Without the intake of sufficient electrolytes this can make you very sick.

The reason this nonsense about hydration is current is for one reason only. People are advertising crappy health drinks by running dubious studies and trying to instil health fears in their potential customer base.

You get the best hydration from water, and you should take water when you get thirsty It’s actually as simple as that.
