FATIGUE: Understanding the causes and solutions to regain energy

What is fatigue?

Fatigue is a signal sent by the body indicating a need for recovery. It can occur after physical exertion, mental overload, lack of sleep, or a prolonged period of stress .

Unlike occasional fatigue, persistent fatigue does not disappear completely with rest. It may therefore indicate a more global imbalance involving metabolism, the nervous system, or digestion .

Physical, mental and emotional fatigue

• Physical fatigue : a feeling of muscle weakness or lack of endurance
  
• Mental fatigue : difficulty concentrating, feeling of mental fog
  
• Emotional fatigue : psychological weariness, loss of motivation
  

These forms of fatigue are often interconnected and can influence each other.

Chronic fatigue is characterized by a feeling of persistent exhaustion, present for several weeks or months, and only slightly improved by rest.

It can be associated with prolonged stress, poor sleep, mental overload, or physiological imbalances. Chronic fatigue often affects digestion , concentration, and stress resistance.
