Many people complain of being tired, for one reason or another. Perhaps they are stressed out or worried, or are suffering from insomnia. An underlying problem with fatigue, however, may be dehydration. Many people don't get the daily amount of water they need.
Body of Water
The body is about 70 percent water, and small fluctuations in that percentage can be felt quickly. As water levels decline, so do the levels of nutrients needed to keep the body functioning, such as salt and potassium.
Cleansing and Restoring
When a person drinks water, the water works to flush and rehydrate the body. Not drinking enough water regularly slows the cleansing process and lowers the percentage of fluid in the body.
From Dehydration to Fatigue
Fatigue is felt because the volume of blood in the body is reduced as dehydration grows worse. That makes the heart pump less efficiently. As dehydration progresses, the body has a harder time diffusing internal heat, and tension is created through the body in muscles, joints and organs. That tension often manifests itself as fatigue.
