Sweating

Sweating, or perspiration, is a normal phenomenon in humans but not one we can control.

Sweating and Heat Loss:

The evaporation of the water from the skin takes heat away from the body and so sweating is essential for our temperature control. If we didn’t sweat at all, we could overheat especially after exercise or on very hot days.

In the animal kingdom, we find that humans are the smallest animals that sweat. Larger animals, such as elephants, depend on sweating as well as other behavioural patterns to control their temperature; such as putting dirt over their backs to protect their skin from the sun, staying in the shade or going into water when available. Elephants also flap their ears to radiate heat out of the blood that flows through the blood vessels in the ears.

Sweat Glands – Eccrine and Apocrine Sweat Glands:

Sweat is produced from the “Sweat Glands” – the watery sweat comes from the Eccrine glands deep in the dermis (skin) and the more greasy type of sweat that can smell comes from the Apocrine glands, that are usually found around the hair follicles.

Sweat and Toxins Removal:

Sweat is mainly water. As it is produced from the blood, it does have some salts in it – sodium ions, chloride ions and urea. In people with heavy metal poisoning, some of the metal can be found in the sweat. However, despite many people thinking that sweat gets “rid of the toxins”, it is not a major way for toxins to be got rid of by the body.

The Control of Sweating in the Body:

The control of sweating in the Human is mainly via the sympathetic nervous system and the adrenaline and noradrenline, the stress hormones that are released in conjunction with this.

Our sweat control mechanism is not voluntary as humans and as such why sweating just happens and not able to stop it when we dont want to.

To be able to treat excessive sweating – it is essential to understand this chain. The treatments for excessive sweating or hyperhidrosis all work on certain parts of this chain.
