Chronic fatigue can result from a variety of factors. A specific character trait, compulsiveness, can lead to continuous fatigue. Many people constantly feel that they cannot rest until they finish everything that needs to be done at one time. These people are usually perfectionists, tense and cannot relax unless they complete the whole job, no matter how tired they may be.
Certain physical conditions can cause fatigue. Anemia is a very common ailment leading to tiredness. It is known as ‘tired blood’ disturbance. In anemia, very little oxygen reaches the tissues and as a result, the energy cannot be produced normally. This causes constant tiredness and mental depression. Anemia usually results from deficiencies of iron and vitamin B12.
Sometimes deficiencies of vitamin B6 and folic acid are also involved. Insomnia or lack of sleep can be a cause of torturing fatigue. Sleep induced by sleeping pills and other drugs do not banish fatigue. Intestinal parasites can also lead to fatigue as they rob the body of good nourishment and gorge themselves on rich red blood. Other ailments which can cause fatigue are low blood pressure, low blood sugar, any kind of infection in the body, liver damage, a sluggish thyroid and allergy in foods and drugs caused by additives including artificial flavors, colors, and preservatives.
Mental tension is one of the major causes of fatigue. A person who is tense and cannot relax has all the muscles of their body more or less contracted. This leads to a needless waste of large amounts of energy. Food is continuously burnt; lactic acid accumulates more rapidly than it can be carried to the liver for conversion to body starch. People who are high-strung, nervous and irritable usually suffer from fatigue.
