Fatigue or the inability to continue functioning at the same level of normalcy is becoming more common in modern life. It is often caused by a lack of energy to the point of exhaustion. This condition is normal, but it can be hazardous if it becomes constant. Constant fatigue is called Chronic Fatigue Syndrome (CFS). Individuals who suffer from CFS may have a hard time working efficiently and feel weary and irritable. The real causes of fatigue are still unknown, but doctors and other health specialists suggests that two of the major causes of this condition is depression and vitamin deficiency.

Depression is one of the major probable causes of CFS. Some factors that may contribute to depression can be life altering events that cause mental and physical exhaustion. Family problems like divorce, child care, and other issues may eventually cause depression. In addition to these factors, depressed individuals easily get tired because these individuals produce less cortisol, a hormone that is produced by the adrenal gland. Scientists found out that people with CFS sometimes produce less cortisol and probably affect the immune system.

Many medical studies show that individual who suffer CFS suffer from vitamin deficiency. People need vitamins and minerals for good health, proper well-being, and energy. People with low vitamin levels tend to be tired, weak, and sometimes irritable.

Other symptoms of CFS may include the following:

?night sweats

?weight change

?breathing difficulties

?swollen lymph glands

?persistent feelings of thirst

Individuals who suffer from CFS are encouraged to engage in active lifestyles and healthy food regimens. Including exercise and other physical activities as part of a daily routine may promote the release of endorphins, which are chemicals released by the brain that are said to promote feelings of bliss and elevates mood. Exercise may also improve blood circulation and oxygenation to various parts of the body and prevent CFS of developing.

Health specialists also advise these individuals to take B complex vitamins. These vitamins includes a group of eight vitamins which includes thiamine (B1), roboflavin (B2), niacin (B3), pyridoxide (B6), folic acid (B9), and cyanocobalamin (B12). These B-complex vitamins may help fight fatigue and is vital nutrient for the formation of red blood vessels. These blood vessels are linked to the human body's energy levels. These B-complex vitamins work by maintaining the energy levels high. They can also help prevent the development of some diseases because they may aid in the repair of nucleic acids and the immune cells.

Most people who take B complex vitamins notice increased energy immediately because this kind of supplementation converts carbohydrates into glucose, which is converted by the cells into energy.

Physical activity coupled with B-complex may prevent CFS and lead to improved overall health.

However, individuals who want to include physical activities and vitamins in their daily routines should seek the approval of doctor, nutritionists, and other health professionals. Some exercise routines may not be appropriate for some individuals and B-complex vitamins may interact with other drugs and supplements and develop unwanted side effects. These professionals may devise a health program and food regimens that are appropriate for the development of one's health.
