Stress, particularly chronic stress, is considered a potential trigger for ME/CFS. It is also thought to worsen ME/CFS symptoms. ME patients are usually advised to avoid stress wherever possible.

Notable studies[edit | edit source]

Several studies found it is not uncommon to experience major psychological chronic stress (from events such as divorce, bereavement or serious financial worries) in the year prior to developing ME/CFS.[1][2][3] Chronic psychological stress elevates cortisol which suppresses the Th1 antiviral/intracellular immune response,[4] and the T-cell response.[5] As ME/CFS normally appears after acute viral infection, the presence of chronic stress may alter the immune response to such infections.

Myalgic encephalomyelitis or chronic fatigue syndrome, often used when both illnesses are considered the same.

Myalgic encephalomyelitis or M.E. has different diagnostic criteria to chronic fatigue syndrome; neurological symptoms are required but fatigue is an optional symptom.<ref name="ICP2011primer">{{Citation
