Why is my baby's palm and sole hot while body temperature is normal?

A baby may have warm palms and soles despite normal body temperature due to either physiological or pathological factors, such as micronutrient deficiencies or hyperthyroidism.

I. Physiological Factors

Since a baby's organs are not yet fully developed, wearing excessively thick clothing or being in an overly warm indoor environment can prevent proper heat dissipation from the skin surface, leading to warm palms and soles. Symptoms typically improve by lowering room temperature or reducing the amount of clothing.

II. Pathological Factors

1. Micronutrient Deficiencies

Babies with poor dietary habits may develop deficiencies in essential trace elements. This can increase neuromuscular excitability, placing the body in a state of irritability, resulting in warm palms and soles despite normal body temperature. It is recommended to take supplements such as vitamin D drops, calcium gluconate oral solution, or calcium carbonate D3 granules under medical guidance to replenish necessary micronutrients and alleviate symptoms.

2. Hyperthyroidism

Abnormal secretion of thyroid hormones increases the basal metabolic rate, often causing warm hands and feet even when body temperature remains normal. Under medical supervision, medications such as methimazole tablets or propylthiouracil tablets may be prescribed to suppress thyroid hormone production and relieve symptoms.

In addition, conditions such as rheumatic fever could also be potential causes. Specific diagnoses require appropriate medical evaluations at a hospital, followed by timely and standardized treatment.
