You also lose salts sweating, so if you drink water, sweat, and don’t replace salts in your blood the inside now saltier parts of your body (like your brain) can pull water out of your blood and swell up, and your brain is trapped in your skull and has nowhere to expand to. Even if you lose lots of water sweating you can still get edema from too much water. You also lose water to respiration which doesn’t take salts with it.
I’ve never been super careful about it exercising. I just drink only when I’m thirsty, and hate the taste of gatorade, so if gatorade tastes good I drink that until it doesn’t, and if it doesn’t taste good and I’m thirsty I drink water. Or if my pee isn’t clear I drink water.
well, too much water can actually lead to death or coma (trust me, I saw a video on this!)
That’s why I specifically included the case where I thought that much water might be alright (because you’re losing a lot of water sweating)
