Why does the body feel hot but also cold without a fever, and what should be done?

Generally, feeling hot in the body while perceiving cold without actual fever may be caused by physiological factors or pathological conditions such as hypoglycemia or hypothyroidism. Symptomatic treatment should be based on specific circumstances. Details are as follows:

I. Physiological Factors

In women, ovulation or menstruation periods, as well as high stress levels, may lead to a sensation of feeling cold despite the body being warm. This is a normal phenomenon. It is recommended to ensure adequate rest and maintain a relaxed mood; usually, no special treatment is required.

II. Pathological Factors

1. Hypoglycemia

Hypoglycemia can reduce the body's perception of warmth, causing a slight feeling of chilliness. It may also trigger symptoms such as headache, sweating, and dizziness. To prevent hypoglycemia, it is advisable to eat smaller meals more frequently and choose low-sugar, high-fat, and high-protein foods, avoiding excessive hunger.

2. Hypothyroidism

Insufficient secretion of thyroid hormones may lower body temperature, leading to a sensation of feeling cold without fever. This condition is often accompanied by other symptoms such as fatigue, constipation, and dry skin. Patients are advised to take medications such as thyroid tablets or levothyroxine sodium tablets as prescribed by a doctor.

Besides the above, other possible causes include trauma, perimenopausal syndrome, and Raynaud's disease. Individuals experiencing discomfort should seek timely medical attention to avoid delays in treatment. Additionally, maintaining a light diet and ensuring adequate rest in daily life is recommended.
