What does it mean when an adult's body temperature is 35.6°C? Is it a low-grade fever?

Generally speaking, low-grade fever refers to mild fever. A body temperature of 35.6°C in adults is not considered a low fever; it may be caused by environmental factors, improper diet, hypoglycemia, anemia, hypothyroidism, or other conditions. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Environmental Factors

In cold environments, the body may slow its metabolic rate to conserve energy and maintain basic life functions, leading to a lower body temperature. Taking proper measures to stay warm and avoiding exposure to cold with inadequate clothing can help alleviate this condition.

2. Improper Diet

Prolonged insufficient food intake or extreme dietary habits may lead to inadequate energy reserves, affecting normal metabolic processes. When energy is deficient, the body may reduce metabolism, resulting in decreased body temperature. Maintaining healthy eating habits and regular mealtimes contributes to overall health.

3. Hypoglycemia

Skipping meals for extended periods may lead to low blood sugar (hypoglycemia), causing insufficient energy supply and affecting metabolism, which may result in lowered body temperature. This condition is often accompanied by other symptoms such as sweating, dizziness, and fatigue. Under medical supervision, medications such as Ejiao Buxue Granules, Shengmai Yin, or Glucose and Sodium Chloride Injection may be used for treatment.

4. Anemia

Long-term picky or unbalanced eating may lead to malnutrition and subsequently cause anemia. Patients may experience symptoms such as headache, dizziness, and pale skin, and may also develop a lower-than-normal body temperature. Treatment may include iron supplements like Ferrous Gluconate Syrup, Iron Dextran Granules, or Vitamin B12 Tablets, taken as directed by a physician.

5. Hypothyroidism

Hypothyroidism occurs due to insufficient secretion of thyroid hormones. Patients may experience symptoms such as abdominal bloating and anemia. Because thyroid hormones regulate metabolism, patients may also present with abnormally low body temperature. Under medical guidance, medications such as Levothyroxine Sodium Tablets, Thyroid Tablets, or Alfacalcidol Soft Capsules may be prescribed to support recovery.

Maintaining healthy lifestyle habits is important. Engaging in appropriate physical activities such as running, jumping rope, or swimming can help strengthen the immune system and promote overall health.
