about Fatigue & Energy

Physical fatigue, emotional fatigue, mental fatigue... Perhaps you, like nearly half of French people, have already experienced a period of intense fatigue. Whether it's a temporary loss of vitality or chronic exhaustion, these situations have an impact on daily life: sleep disorders, irritability, cognitive overload, hypersensitivity, lack of energy and motivation, etc.

This natural phenomenon is very common: after a busy day, sustained physical effort, or a period of stress, it is a signal that the body sends to encourage us to recover. Often, a good night's sleep allows us to recharge our batteries for the next day. But when it becomes persistent, it can profoundly impact our quality of life.

Physical fatigue is closely linked to muscle function, tissue oxygenation, and the production of ATP, the key molecule in energy metabolism. Mental fatigue, on the other hand, involves the brain, which is a major consumer of energy, and depends on the balance of neurotransmitters, sleep, stress, and mental load. When these systems are overworked or overused for prolonged periods, the body struggles to maintain a stable energy level.

In this guide, explore the mechanisms of fatigue, its signs, and the consequences of prolonged exhaustion. You'll also discover valuable tips for supporting your energy metabolism and boosting your vitality: healthy lifestyle, stress management, sleep optimization, and nutritional support.
