I mean sure, that's sort of a given. Are you suggesting you don't piss?
Maybe you just hike differently to what I assumed.
I do the occasional hike anywhere from 4-8 miles and I usually drink an extra 1-2L for the day - that's how I reckon I'd double my intake for a 12-15 mile hike.
I don't piss like a race horse, the hikes are in 95-105 degree weather, and I go at pace. To each their own.
I'm definitely not headed to the bathroom every half hour, like I would be if I drank 4 liters of water ever day. What exactly needs that much replenishing working at a computer in the air conditioning most of my day?
Military suggests roughly 4 liters for an active person, for an entire day. Even adding another liter for strenuous and in dry climates, that's far less than 8 liters.
4L of fluids, currently around 3L of water + 1L of milk.
If you're awake for around 16 hours, not sure why drinking an average of 500ml of fluids every 2 hours seems excessive to you. Or why drinking 1L of fluids every 2 hours (when your agenda for the day includes doing a 15 mile hike in hot weather) is considered a lot.
If what I've described above would make you go to the bathroom every 30 mins, perhaps see a doctor.
That's the point, you said double it. 8L is a ton of water, even when active. No one is carrying that much, even the military. 4L is excessive for a normal day not being active.
I appreciate the feedback, but perhaps don't tell me what to do.
I mean, this is a funny troll, but I hope nobody actually packs 16 liters of water for a one day hike. This is a recipe for hyponatremia, a rare yet serious condition of too low blood sodium levels from overhydration.
I don't think most adults should need more than 3 liters of water for a day long hike if they are already properly hydrated. The idea is to hydrate for 24 hours before you exercise. Then during the exercise, you take small sips occasionally. After an hour, you may need to begin replacing lost electrolytes. You also want to drink more often at high elevation and in the cold.
You can actually check how much water you'll need during exercise. Weigh yourself, exercise for an hour, and weigh again. The lost weight is the water you lost and need to replenish.
In any case, you should be peeing every 2 to 4 hours. If the water is clear, you're hydrated. If the water is dark yellow, you're really not hydrated.
