Dehydration is a condition that occurs when a person loses more fluids than he or she takes in. Dehydration isn't as serious a problem for teens as it can be for babies or young children. But if you ignore your thirst, dehydration can slow you down.Our bodies are about two thirds water. When someone gets dehydrated, it means the amount of water in his or her body has dropped below the level needed for normal body function. Small decreases don't cause problems, and in most cases, they go completely unnoticed. But losing larger amounts of water can sometimes make a person feel quite sick.
Preventing Dehydration
The easiest way to avoid dehydration is to drink lots of fluids, especially on hot, dry, windy days. Water is usually the best choice. Drinking water does not add calories to your diet and can be great for your health.The amount that people need to drink will depend on factors like how much water they're getting from foods and other liquids and how much they're sweating from physical exertion.
Occasionally, dehydration might be a sign of something more serious, such as diabetes, so your doctor may run tests to rule out any other potential problems.In general, dehydration is preventable. So just keep drinking that H2O for healthy hydration.
