What should be done if an adult's body temperature is 35.5°C?

　　An oral, axillary, or rectal body temperature of 35.5°C in adults is considered low and may be related to factors such as low ambient temperature, prolonged immobility, medication effects, hypoglycemia, or hypothyroidism. Treatment may involve lifestyle adjustments or medication use.

　　1. Low ambient temperature: Prolonged exposure to cold environments can cause the body to lose heat in order to adapt, resulting in a drop in body temperature. It is important to wear appropriate clothing and maintain warmth.

　　2. Prolonged immobility: Remaining inactive for extended periods—such as long-term bed rest or coma—can lead to decreased body temperature.

　　3. Medication effects: Certain medications, including sedatives, antidepressants, and anti-anxiety drugs, may affect the body's temperature regulation center and cause a reduction in body temperature. Dosage adjustments or switching to alternative medications under a doctor’s guidance may be necessary.

　　4. Hypoglycemia: Low blood sugar can disrupt energy supply and impair metabolic processes, making it difficult for the body to maintain normal temperature. Treatment under medical supervision may include medications such as Ejiao Buxue Granules or Shengmai Yin.

　　5. Hypothyroidism: The thyroid gland regulates metabolism. When thyroid function is reduced, the body's metabolic rate may slow down, leading to lower body temperature. Under medical guidance, treatment may include levothyroxine sodium tablets or thyroid tablets.

　　If you have any concerns, consult a doctor for an accurate diagnosis and appropriate treatment recommendations.
