Heart-kidney disharmony (heart-fire exuberance and kidney-yin deficiency, dysfunction of the physiological functions of the heart and kidneys) may cause insomnia, heartburn, forgetfulness, tinnitus, lumbar and knee soreness and weakness, dreaming, hot flashes, and night sweating (sweating abnormally after going to sleep, and sweating stops after waking up). In Chinese medicine, Heart and Kidney Disorder is a type of evidence that refers to the imbalance of both heart and kidney water and fire. In the function of internal organs, the heart on the fire, the kidney in the subordinate water, the heart fire should be down so that the kidney water is not cold, the kidney water should be up to the heart, so that the heart fire is not hyperactive, called the heart and kidney intersection, water and fire. If the Heart and Kidneys do not intermingle, pathological changes will occur. 1. Upset heart, insomnia: Kidney yin deficiency, kidney water can’t go up to the heart, resulting in heart fire, disturbing the heart and mind, resulting in insomnia, irritability, dreamy, etc. 2. Forgetfulness, tinnitus, lumbar and knee pain and weakness: Kidney is the main bone and marrow generator (meaning that kidney controls the production of bone marrow and affects the growth and development of bones), kidney opens the orifices of the ear, and with deficiency of kidney yin, the kidney essence cannot moisturize the bones, brain marrow, and the orifices of the ear, which leads to forgetfulness, tinnitus, and lumbar and knee pain and weakness. 3. Dreaming: Deficiency of kidney yin, internalized fire, and lack of solidity of the essence chamber, leading to dreaming and wetting. 4. Hot flashes and night sweating: deficiency of kidney yin, yin deficiency leads to hyperactivity of yang, and internalization of deficiency heat, resulting in hot flashes and night sweating. It is important to note that if you are not feeling well, please go to the hospital in time and take medication under the doctor’s guidance to avoid delaying your condition.
