Getting adequate sleep is extremely important for good mental and physical health. Fatigue is often a sign that someone is getting inadequate sleep. "While most fatigue has root causes that are not medical in nature, a persistent lack of energy can be a sign of a serious problem, such as a thyroid disorder, anemia, depression, chronic fatigue syndrome or cancer. It is very important to see your doctor if fatigue persists." The Center For Creative Balance is dedicated to helping find balance in an unbalanced world.
