Anemia
Anemia is a deficiency or misfunction of the red blood cells you need to transport oxygen throughout the body. There are several different kinds of anemia, each requiring a different kind of treatment.
Symptoms of anemia include weakness, chest pain, headaches, cold hands or feet, and irregular heartbeat. However, dehydration is both a common symptom and major contributor to other symptoms, making healthy hydration an effective way to counteract the condition.
