When we need to fall asleep, usually after eating, it is often a sign that our liver is working hard! (Metabolic fatigue)
Fatigue without physical exertion, even after a good night's sleep, is widespread today. Chronic inflammations in the body create a condition of chronic metabolic fatigue. Most often, the cause is an imbalance in the intestinal flora.
A distinction can be made between four types of fatigue:
- Muscle fatigue - (Muscles) Often due to the muscles' exertion (not necessarily aerobic). Such as holding a child in your arms and standing still.
- Muscle fatigue is a result of lactic acid formation. Usually, within a few minutes, the pain will go away.
- Aerobic fatigue - (Heart and Lungs) Fatigue results from physical exertion, sports activities, climbing stairs, carrying loads, etc. Its manifestation is often associated with high heart rate, rapid breathing, muscle aches, and sweating.
- Aerobic exertion activates the heart and lungs; therefore, the pulse and respiration rate increase. Sweating is a mechanism designed to cool the body.
- Metabolic fatigue - (Liver and Kidney) Most often due to a heavy meal or chronic inflammatory diseases. The manifestation of metabolic fatigue is a desire to take a nap.
- Metabolic fatigue is fatigue of the liver and kidneys that work very hard, usually after large meals. The liver is the most energetic organ in the human body! The need for drowsiness reflects the direct connection between the liver and the eyes. (According to Chinese medicine)
- Spiritual and mental fatigue - (Brain and Subconscious) Usually after unpleasant or traumatic events. The manifestation of mental fatigue is a poor mood, a tendency to outbursts, closure, and social distance.
- The brain is a very energetic organ; unpleasant and traumatic events are often stored in the subconscious mind. (As part of the defense mechanism of the mind) These processes impair the mood and the general energy level of the body.
When we say we are tired, we often mean metabolic fatigue because it is not related to physical exertion but to a physiological effort, we are unaware of.
