The human body is 65% water. Simply put, dehydration occurs as the result of excessive loss of water from the body — when we lose more water than we take in. It's a bit more complicated than that since the body loses valuable electrolytes as well. That's why sports drinks have become so popular; they replenish electrolytes as well as just fluid. Dehydration can be a major issue, both in and of itself and as a Migraine or headache trigger. Many people mistakenly think dehydration occurs only in hot weather, and that you're not dehydrated if you're not thirsty. Both of these misconceptions lead to many cases of dehydration every year, some of them quite serious.

"Regular" dehydration from air conditioning and/or fans is unlikely unless you're already bordering on dehydration.
