Sweating in the morning can be caused by high temperature or kidney yin deficiency. If the room temperature is too high or the blanket is too hot when sleeping in the morning, it may lead to morning sweating. In addition, kidney yin deficiency may also lead to morning sweating. Kidney yin deficiency is usually caused by insufficient yin fluid in the kidneys, and patients usually experience symptoms such as dizziness and tinnitus, five heart-heat (heat in the palms of the hands and the hearts of the feet, and self-consciousness of being hot in the chest and the heart), night sweating (sweating abnormally after falling asleep, but stopping after waking up), and insomnia and excessive dreaming. Among them, the five heart-heat may cause the patient to feel that his or her hands and feet are hot and irritable, and there will be morning sweating of the feet. If morning sweating occurs for a long time, you should go to the hospital in time to clarify the cause of the disease, and under the guidance of the doctor for treatment.
