Feeling Completely Drained and Lethargic? Qi Deficiency Makes Muscles Weak

From the perspective of modern medicine, qi deficiency in Donguibogam can be understood as an overall decline in our body's energy production and utilization systems. The energy required for all bodily activities comes from a substance called adenosine triphosphate (ATP), which is produced in tiny cellular power plants called mitochondria. Chronic stress, irregular meals, sleep deprivation, and overwork degrade the function of these mitochondria and hinder adenosine triphosphate production. As the operating rate of these power plants drops, the entire body naturally runs out of energy, leading to overall lethargy and muscle weakness. Furthermore, muscle movement occurs when signals sent from the brain are transmitted to the muscles through the neuromuscular junction. Neurotransmitters such as acetylcholine play a crucial role during this process, but in a state of qi deficiency, the synthesis or function of these neurotransmitters may falter, preventing commands from reaching the muscles properly. It is just like an electrical signal becoming so weak that pressing a switch makes the light turn on dimly or not at all. Consequently, the muscles fail to exert proper strength and tire easily. In addition, an imbalance in our endocrine system, particularly in thyroid hormone or corticosteroid (cortisol), causes symptoms similar to qi deficiency. Thyroid hormone regulates our body's metabolic rate, and cortisol is deeply involved in the stress response and energy metabolism. When their function declines, general lethargy, fatigue, and muscle weakness can accompany it. Rather than assuming you lack strength simply due to aging, please remember that this is an error signal from complex bodily systems, signaling that it is time to inspect your body's engine.
