Is a body temperature of 35.5°C normal?
Generally speaking, a body temperature of 35.5°C does not fall within the normal temperature range. However, if it is caused by physiological factors, it may be considered a normal phenomenon; if it results from pathological factors, then it is not considered normal. If abnormalities are present, timely medical consultation is recommended. Detailed analysis is as follows:

The normal body temperature for humans is generally between 36°C and 37°C. However, body temperature can be influenced by various factors, such as environmental conditions, measurement methods, medications, and diseases. Prolonged exposure to cold and dry air may cause a temporary drop in body temperature, potentially reducing it to 35.5°C. Timely warming measures can help restore normal body temperature. Certain medications, such as antipyretics, may also cause a decrease in body temperature, which is a normal phenomenon under the influence of the medication.
However, if a body temperature of 35.5°C is accompanied by symptoms such as fatigue, dizziness, or chills, it may be associated with certain diseases, such as severe malnutrition, hypothyroidism, or hypoglycemia. These conditions can affect the body's metabolic and heat-producing functions, resulting in a decreased body temperature, which is not considered normal.
Therefore, if someone usually maintains a normal body temperature but suddenly develops a temperature of 35.5°C along with discomfort symptoms, prompt medical consultation and examination are recommended to determine the underlying cause and provide targeted treatment.
