Hypothermia 35.5℃

Generally, a body temperature of 35.5°C may be caused by factors such as cold environment, malnutrition, drug side effects, hypothyroidism, or meningitis. The specific analysis is as follows:

1. Cold Environment

Prolonged exposure to extremely cold environments can lead to decreased body temperature. When the body cannot effectively generate and retain heat, body temperature may drop, resulting in hypothermia at 35.5°C. Symptoms usually improve after leaving the cold environment.

2. Malnutrition

Long-term picky eating or unbalanced diet leading to malnutrition may result in insufficient energy supply for the body, reducing internal heat production and causing low body temperature. Maintaining a balanced diet in daily life contributes to overall health.

3. Drug Side Effects

Long-term use of sedatives, antidepressants, or analgesics may affect the body's temperature regulation center, leading to a decrease in body temperature. Symptoms typically improve after discontinuation of the medication.

4. Hypothyroidism

The thyroid gland is one of the key organs responsible for producing and regulating body temperature. Hypothyroidism means the thyroid cannot produce sufficient thyroid hormones normally, which may lead to a slowed metabolism and reduced body temperature. Under medical guidance, patients may take medications such as levothyroxine sodium tablets to alleviate symptoms.

5. Meningitis

Bacterial infections causing meningitis can affect the body's temperature regulation center due to inflammatory stimulation, potentially leading to a drop in body temperature to 35.5°C. It is recommended to seek timely medical attention and, under a doctor’s guidance, receive treatments such as acyclovir tablets or ceftriaxone sodium injection.

If unexplained low body temperature occurs, prompt medical consultation is advised to avoid delays in treatment. Maintaining healthy lifestyle habits and proper body warmth in daily life can support recovery.
