What causes the sensation of heat in the soles of the feet?
Feeling heat in the sole of the foot may be caused by physiological factors or pathological conditions such as varicose veins or hyperthyroidism. The specific analysis is as follows:
I. Physiological Factors
If the feet are exposed to hot environments for prolonged periods—such as high summer temperatures or hot ground surfaces—it can lead to a sensation of heat in the soles.
II. Pathological Factors
1. Varicose Veins
Patients with varicose veins often experience poor venous return in the lower limbs, leading to blood stasis in the leg veins. Accumulation of metabolic waste products increases local temperature, resulting in a feeling of warmth.
2. Hyperthyroidism
Hyperthyroidism can increase the body's metabolic rate, causing excessive heat production. Since the soles of the feet are one of the body's heat-dissipating areas, they may feel warm when the body is overworking.
In addition, this symptom could also be caused by multiple sclerosis. It is recommended to seek timely medical evaluation at a hospital to identify the underlying cause and receive appropriate treatment.
