I am curious about some techniques/guidelines for achieving and maintaining optimal hydration while performing moderate to high strain outdoor activities, such as long hikes etc. IOW, how do you hydrate yourself JUST ENOUGH, not too much, not too little.
The reason that I am asking is that I noticed that, when not sweating too much and not peeing, I don't need too much water. Excessive water intake causes more urination, which means you have to make more frequent stops and also your organism "learns" to use more water, i.e. gets adjusted. So I am thinking there could be techniques for optimal and balanced hydration that do not rely simply on thirst or a pre set water intake schedule and instead is perhaps a function of drinking water only after urination and in the amount that is approximately commensurate to the amount of urine.
