A body temperature of 35.5°C is a state of hypothermia, which may be caused by improper measurement operation, environmental factors, drug factors, and pathological factors.
1. Improper measurement operation. Axillary body temperature if the measurement time is relatively short, such as only 1 to 2 minutes. Due to insufficient conduction of body temperature, it may lead to low measurement value. Or the thermometer position is not accurately placed during measurement, resulting in measurement error.
2. Environmental factors. Being in a cold environment for a long time and not paying attention to preventing cold and keeping warm leads to low basal body temperature, and the body temperature may be relatively low during measurement, so it is recommended to pay attention to preventing cold and keeping warm.
3. Drug factors. Patients with fever, after taking antipyretics, sweat a lot, which can take away the body heat. If you take a temperature measurement, your body temperature may be slightly lower.
4. Pathologic factors. Prolonged bed rest, old age and frailty, hypothyroidism, anemia, low metabolic level of the body, can also lead to low body temperature.
It is recommended to re-measure the body temperature first. If the temperature is still low after repeated measurements, you should go to the hospital for examination under the guidance of the doctor to clarify the cause of the disease and treatment.
