What organ is insomnia?

Insomnia may be related to problems in the brain, heart, liver, kidneys and other organs. 1. Brain The brain is the key organ that controls sleep and wakefulness. When the brain's neurotransmitters are unbalanced, such as serotonin, dopamine and other abnormal secretions, it will affect the sleep regulation mechanism, resulting in difficulty falling asleep, shallow sleep or easy waking. If the biological clock system of the brain is disordered, it will also disrupt the normal sleep rhythm. 2. The health of the heart may also affect sleep. When the heart function is not good, it may lead to poor blood circulation in the body, causing palpitation, chest tightness and other discomfort, and then interfere with sleep. 3. Liver function also has a certain impact on sleep. The liver is responsible for metabolism and detoxification. If the liver function is abnormal, it may lead to the accumulation of toxins in the body, affecting the normal physiological function of the body and indirectly affecting the quality of sleep. 4. Kidney Kidney plays an important role in maintaining the balance of water and salt in the body. Abnormal kidney function may cause edema and other problems, which may make people feel uncomfortable during sleep and affect sleep. Insomnia is often the result of a combination of factors, involving multiple organs and systems such as the brain. When insomnia occurs, all factors should be considered comprehensively, and a comprehensive assessment and diagnosis should be made in order to take appropriate treatment measures to improve sleep conditions.
