Sweating at night may be caused by high room temperature, tuberculosis, rickets and other reasons. 1. High room temperature: If the temperature of the sleeping environment is high, it can lead to an increase in the body’s heat dissipation and night sweating, which is a normal physiological phenomenon. 2. Tuberculosis: its main symptoms are night sweats, low fever, emaciation, etc., which can be manifested as night sweating in bed. 2. Rickets: due to a long time lack of vitamin D, resulting in calcium and phosphorus metabolism disorders, can appear sleep disturbance, night crying, excessive sweating, occipital baldness and other symptoms. Parents keep the room temperature suitable when the child sleeps, and if there are other uncomfortable symptoms, they should go to the hospital in time, clarify the cause of the disease, and standardize the treatment under the guidance of the doctor.
