I spend most of my time in nice air conditioning, but there are a few times when I anticipate allot of excercise where I'm at risk of dehydrating to the point that I will develop a headache. Usually when playing with toddlers outside that make me do all the heavy lifting ;) I'm learning to be more cautious of this, but it still seems like it happens a bit too often.
My first question is what to do once I already have a headache from dehydration. I've tried simply chugging allot of water, but this just seems to lead to excessive restroom breaks, and it still takes half a day for the headache to go away. The water seems to go through me without being absorbed or doing anything to stop a headache once it's started. Is there a way both to speed up the process so the headache goes away faster and to avoid excessive restroom breaks in the process? Is there only so much water I can drink at once and beyond that it's not going to help hydrate faster?
Second is how do I avoid getting dehydrated so fast? I feel like even when i go into a situation worried about getting dehydrated and drinking many bottles of water I still end up with a headache. I may not be drinking enough because I'm worried about just needing lots of restroom breaks, but is there something else I should be doing when I'm expecting to sweat allot that will help avoid getting a headache? Preferable something that doesn't take me away from my activities too often :)
