Body temperature below 36 degrees may be physiological factors, but also may be disease factors, such as shock, burns, serious infections, endocrine diseases and other disease precursors. 1. Physiological factors: such as in the process of temperature measurement inappropriate operation method caused by the measurement error. Secondly, we also need to consider the surrounding environmental factors, if in too cold environment, there may also be the phenomenon of low body temperature. 2. Shock: Shock often leads to a decrease in body temperature, which is commonly caused by a change in the distribution of blood circulation, a decrease in blood volume, excessive blood loss, and so on. 3. Burns: Acute injuries such as burns can cause damage to the endothelial cells of blood vessels, resulting in impaired blood circulation and a drop in body temperature. 4. Serious infections: some patients may also drop below 36 degrees when they have serious infections in their body. 5. Endocrine diseases: For example, endocrine diseases such as hypoadrenocorticism, hypothyroidism, etc. make the body hypothermic and may also cause the body temperature to drop below 36 degrees. The causes of body temperature below 36 degrees are very complex, it is recommended to combine the patient’s accompanying symptoms to improve the relevant examination to clarify the cause of the disease, so as to carry out systematic treatment.
