Burnout first results in physical signs: permanent fatigue, back pain, insomnia, migraine, stomach aches, frequent infections, etc. Psychic suffering can also manifest itself: emotional emptiness, anxiety in all its forms, irritability, a tendency to isolate oneself, difficulty concentrating, a feeling of being overwhelmed by events or demotivation. The exhausted person can become unusually cold, indifferent, emotionally isolated, and cynical.

The physical signs usually disappear on their own, but this does not necessarily mean that there is a permanent improvement in health.

When working conditions continue to be unsatisfactory, other characteristic signs gradually appear, frustration, the feeling of failure and excessive detachment from events and the environment. Eating disorders may appear, even drug addiction (alcohol, drugs, medication). Exhaustion, when it persists, can also trigger a proven depression which aggravates burnout.

People who suffer from long-term burnout are more likely to develop other health problems such as type 2 diabetes, heart disease, obesity, and overweight.
