Dehydration is more common than you may think. It’s a commonly-known problem, occurring when the body looses too much fluid without having it replenished, but many people think that you only get dehydrated when you’re extremely thirsty and are exercising for a long period of time or stuck out in the Sahara desert with a cup of water and miles of sand between you and the nearest oasis.
Of course, these examples are both true. Many people who do exercise don’t drink enough water while they work out, and since they lose so much fluid through perspiration they do end up dehydrated. The same is true for those trudging through the desert, but these are extreme cases.
Many people become dehydrated through the course of their daily lives because they’re not drinking enough water.
Often this happens gradually, and we’ll hardly notice it until at one point in the afternoon we feel extremely thirsty. If this happens to you, it’s a good indicator that you’ve been dehydrated for awhile, since if you feel thirsty it’s a definite sign of dehydration.
Thirst isn’t the only side-effect; dehydration often leaves people feeling tired, lethargic, sickly, or even faint.
