Heat exhaustion and its more serious counterpart
heat stroke are not to be trifled with. One way to prevent both is to avoid becoming
dehydrated. Athletes and avid exercisers are at risk of dehydration if they sweat profusely and don't replenish themselves while working out.

As the weather slowly turns and you start exercising in warm weather it's important to remember to keep hydrated. This is especially important for asthma sufferers as dehydration has been known to make it worse.
Dehydration can cause bronchospasm, a constriction of the lung airways, which can make exercise induced asthma worse.

After exercising (and during) I always crave some gulps of cool, crisp H2O, but a
new study shows that having a
beer after a workout could do more good than regular water. Hmmm. I'm listening...
In my opinion, the study doesn't hold too much weight since it involved only 25 participants, and they were all college students.

So last night I was sitting on the couch and suddenly my foot cramped, leaving my toes spread wide apart for a good couple of minutes -- Of course I was running around the house screaming like a banshee. About 30 minutes later, the same thing happened, just on the other foot. What gives.

It's summer and it's hot out. Your body produces sweat to cool you off, so in order to make up for that lost fluid, you should be drinking more water. If you don't, you could be at risk for
dehydration.
Our bodies are 2/3 water, so if a person gets dehydrated, it means the amount of water in her body has dropped below the level needed for normal body functioning.
