Why does a person have a low fever of 35℃? Is it dangerous?

Low-grade fever generally refers to a mild fever. A temperature of 35℃ does not fall into the category of low-grade fever in humans. At this temperature, the body's temperature is below the normal range, which may be related to body chills, drug stimulation, hypothyroidism, or brain trauma. If treated promptly, it generally poses no danger; however, delayed treatment may lead to worsened conditions and pose a risk to the body, necessitating immediate medical attention.

1. Body Chills: Prolonged exposure to cold environments can lead to severe body chilling, potentially causing a sustained drop in body temperature to 35℃. It is recommended to stay away from cold environments and add clothing according to weather changes.

2. Drug Stimulation: When patients experience fever, they may be prescribed antipyretic medication. However, taking these medications can sometimes cause the body temperature to drop to 35℃. This is generally a transient reaction, and the temperature should not continue to decline. It is advised to avoid taking large doses of antipyretics.

3. Hypothyroidism: Insufficient thyroid hormone can lead to hypothyroidism, resulting in a decreasing body temperature. Other symptoms may include fatigue and aversion to cold. Treatment typically involves taking medications such as levothyroxine sodium tablets, prednisone acetate tablets, or dexamethasone acetate tablets under the guidance of a doctor.

4. Brain Trauma: Trauma to the brain can lead to decreased brain function, affecting its ability to regulate body temperature. This can manifest as symptoms such as unconsciousness and shock. Prompt surgical treatment at a reputable hospital is necessary to remove any local blood clots. It is essential to closely monitor body temperature changes and adjust treatment plans according to medical advice. Daily habits should include drinking warm water and consuming fresh fruits and vegetables.
