Body fever during midnight sleep is mainly seen in two categories: first, it is caused by disease; Second, it is caused by endocrine imbalance. More commonly, it is caused by diseases, such as bacteria, viruses and other infections, which lead to fever with a body temperature of more than 37.3 degrees Celsius, or tuberculosis caused by Mycobacterium tuberculosis, which leads to fever, night sweats and other conditions. Second, endocrine disorders, such as hyperthyroidism or climacteric fever, night sweats, yin deficiency, dryness and heat, and a series of symptoms. So when fever occurs, first of all, measure your temperature in time to see if it exceeds 37.3 degrees Celsius, and then go to the hospital to further check for infection. If there is no infection, it is considered that it is caused by endocrine disorder, and some drugs are needed to regulate the endocrine to normal, so that the symptoms can be effectively alleviated.
