Hydration (it really is key)

Last Friday night I decided to do bikram, followed by an hour bouldering (like rock climbing, just on smaller walls, with no ropes and slightly harder in my opinion). Pretty intense work outs alone, but together it wasn't as exhausting as I had thought. Well I made a mistake. A big mistake. (Yes I'm human). I didn't properly hydrate between, during, before, or after these activities. I know better than this, however for some reason I didn't drink near enough water. Needless to say, my arms hurt more than they ever have. It took FOUR days for me to recover and be able to continue work on my arms and climb again. I knew it had to be the whole not enough hydration thing. So last night I did the same regime. Bikram at 4:30, downed a bottle of water during and right after, had a premier protein shake, and went climbing, drank another bottle of water throughout climbing. When I got home, oh there was another bottle of water downed (I drink from 24 oz water bottles). I forgot to mention that while at work, I consumed 3 full water bottles as well. (144 oz total that day). Ya know what? I'm not sore today. Well, my back is slightly sore, but that's because I climbed a 5.10 last night (the highest difficulty I've done yet).
Moral of the story: HYDRATE!!!!!
PS, it is difficult at first to get used to drinking that much water, and frequent bathroom breaks become annoying. My trick is I keep a water bottle with me wherever I go. I also try to eat foods that are high in water content (watermelon is a whopping 92% water!)
Here's the "science" behind it:
Two-thirds of the human body is made up of water. Although it is possible to go for a long time without food, people cannot live without water for more than a few days. Every cell and organ depends on water to perform essential functions. The water in your body performs the following functions:
Removes waste and toxins
Transports nutrients and oxygen
Controls heart rate and blood pressure
Regulates body temperature
Lubricates joints
Protects organs and tissue, including the eyes, ears, and heart
Creates saliva
Why it's important to athletes (I consider myself pretty athletic)
Hydration is essential to peak athletic performance. When you do not consume enough liquid or fresh fruits and vegetables to stay properly hydrated, you end up thirsty and light headed. Insufficient hydration fatigues your muscles, reduces your coordination and causes muscle cramps. While working out or playing sports, dehydration compromises the body's ability to cool itself through sweating. This leads to heat exhaustion and in extreme cases a potentially life-threatening condition called heat stroke.
Why it's important for weight loss:
Consume part of the water required for proper daily hydration before your meals to control your appetite according to a study by researchers from Virginia Tech and reported at the 2010 National Meeting of the American Chemical Society. Drinking 16 oz. of water before meals three times a day over a 12-week period increased average weight loss by about 5 lbs., compared with those who did not increase water intake. Researchers could not definitively say what caused the additional weight loss but speculate it fills up the stomach making you feel fuller.
