Men’s night sweating may be caused by factors such as higher room temperature, mental stress and tuberculosis. 1. Higher room temperature: When sleeping at night, higher room temperature will easily make people feel hot, and the human body will emit heat through sweating, which will lead to sweating during sleep. 2. Mental tension: men may sleep at night due to restless sleep and mental tension, which leads to more sweating. 3. Tuberculosis: Tuberculosis can cause fever and night sweats. If men suffer from tuberculosis, the phenomenon of night sweating can occur. Excluding the influence of physiological factors, if the patient sleeps at night sweating symptoms are more serious, it is recommended to go to the hospital for examination, under the guidance of the doctor according to the specific conditions of the symptomatic treatment.
