International Chronic Fatigue Syndrome Awareness Day

International Chronic Fatigue Syndrome Awareness Day is a global observance dedicated to increasing understanding of chronic fatigue syndrome, also known as myalgic encephalomyelitis or M.E./C.F.S. It is a serious, long-term neurological condition characterized by persistent fatigue that does not improve with rest and can significantly affect daily functioning. The day is observed each year on May 12.

History of International Chronic Fatigue Syndrome Awareness Day

International Chronic Fatigue Syndrome Awareness Day was established in 1993. The date, May 12, was chosen in connection with the birthday of Florence Nightingale, whose later life is often discussed in historical accounts as involving symptoms similar to those now associated with M.E./C.F.S.

The condition is defined by ongoing exhaustion that is not relieved by sleep and is often worsened by physical or mental exertion. People living with M.E./C.F.S. may experience a wide range of symptoms, including cognitive difficulties, pain, sleep disturbances, and sensitivity to exertion. The severity and combination of symptoms can vary from person to person, and the exact cause of the condition remains the subject of ongoing research.
