Sweating is essential for temperature regulation. In humans, sweat glands play a vital role and these exocrine glands are found under the skin and are used for regulation of body temperature. There are three types of sweat gland: eccrine, apocrine and apoeccrine. It is the eccrine sweat gland which is responsible for thermoregulation and the other two glands generally produce secretions which are rich in proteins, salt, and fats which evaporates a slower rate as compared to eccrine secretions and therefore reduces the rate of heat loss. The secretory portion of the eccrine sweat gland secretes isotonic fluid into the lumen. The secretion of isotonic fluid involves a few stages. It begins by releasing acetylcholine from periglandular cholinergic nerve ending and then it binds it to cholinergic receptors which are located in the basolateral membrane of the cells of the secretory coil. This activation of cholinergic receptors leads to the mobilization of intracellular calcium and the influx of extracellular calcium into the cytoplasm. This further results in the secretion of sweat.
Sweating is a normal process but some people suffer from excessive sweating and in medical terms, this condition is known as hyperhidrosis. Hyperhidrosis is a chronic autonomic disorder that affects the entire body but it primarily affects face, armpits, palms, and soles of the feet. Hyperhidrosis is characterized by the visible sweat, wet cloth and a clammy handshake and this condition can lead to an emotional and social embarrassment.
- Localised symmetrical hyperhidrosis - It is also known as focal or primary hyperhidrosis and it is the common type of hyperhidrosis. It affects the localised body sites and affect both the sides equally. The body areas such as palms, soles, underarm skin, face, and scalp are the most affected areas.
- Generalized hyperhidrosis - It is also known as secondary hyperhidrosis. This type of hyperhidrosis is caused due to certain infection or body illness and it affects the entire body.

This disorder is more common in females as compared to the males and it is often accompanied by an irregular heartbeat, trembling hands, irritation, muscle weakness, loss of scalp hair and excessive sweating. Numerous studies suggest that most of the patients with hyperthyroidism have heat intolerance and sweating. Thyroid hormone plays a significant role and is responsible for various body processes. Primarily, it plays a vital role in metabolism and any alterations in the level of hormones affect the functioning of the entire body. Generally, hypothyroidism grows slowly but in some patients, the changes can be very fast.
