Excessive neck sweating is a normal physiological phenomenon because the human body has sweat glands, which are mainly concentrated in the front and back of the neck as well as in the armpits, popliteal fossa and groin. The reason why these areas sweat is because the body needs to expel heat, and when heat gathers inside the body, it will expel heat by way of sweating, so excessive neck sweating is caused by elevated heat in the body. There are also some patients that can cause excessive sweating due to high sweat gland secretion, such as patients with hyperthyroidism, which can cause excessive sweating. Hand sweating can also cause sweating, but the sweating area is mainly in the hands. In Chinese medicine, Qi deficiency can also cause excessive sweating, which can be relieved by taking oral Chinese medicine.
