A woman’s body heat may indicate infectious diseases, connective tissue disease, hyperthyroidism, autonomic disorders, perimenopausal syndrome and other diseases, but also may be the environment temperature is too high and other non-disease factors. 1. Infectious diseases: bacteria, viruses, mycoplasma, chlamydia, fungi and other pathogenic microbial infections, as exogenous pyrogens, triggering the hypothalamus thermoregulation point upregulation, the body through the skin capillary contraction and other pathways to raise the temperature, so the body will be feverish. 2. Connective tissue disease: autoimmune system dysfunction and lead to autoantibodies against the whole body muscle and other tissues to launch an attack, causing non-specific inflammatory response, so the body will be fever. 3. Hyperthyroidism: hyperthyroidism leads to an increase in the synthesis and secretion of thyroid hormones, hypermetabolism of cells throughout the body, and an increase in heat production, so the body is hot. 4. Autonomic disorder: sympathetic nerve excitation and vagus nerve inhibition, resulting in reduced heat dissipation, so the body fever. 5. Perimenopausal syndrome: middle-aged women in about 50 ovarian function decline, estrogen secretion is insufficient, skin capillary dilatation disorders and cause fever. However, it should be noted that women’s body fever may also be strenuous exercise, high ambient temperature, clothing too thick, pregnancy, premenstrual and other conditions, and is not a disease. If you suspect that it is caused by a disease, you should consult a doctor in time.
