Sweating, also known as perspiration, is an essential bodily function. It is a process of producing fluid made of water, ammonia, urea, salt, and sugar by the sweat glands.
Causes of Sweating
Our body’s comfortable temperature is 98.6°F (37°C). At this temperature, our body can work at its best. When the body temperature increases from this comfortable level, our brain tries to regulate body temperature. A signal is sent to a part of our brain known as the hypothalamus, which stimulates the sweat glands to produce sweat. When the sweat comes in contact with the air, it evaporates, cools down the body temperature, and brings it back to the normal temperature.
Apart from the increase in physical heat, emotional stress such as fear, anxiety, anger can also produce sweat. Sweat induced by emotional stress is restricted to palms, soles, armpits, and forehead, whereas sweat induced by physical heat can happen throughout the body.
On average, a human body has 2-4 million sweat glands. But the amount of sweat released by each gland differs from person to person, and the determining factors include gender, genetics, health, and the environmental condition, etc.
Why sweating is important
When sweat comes in contact with the bacteria of our body, it creates a bad smell, often called body odor. Because of this, sweating is always considered unpleasant, and many products such as talcum powders, deodorants, antiperspirants, and perfumes are available in the market to keep the body odour at bay.
Nevertheless, we should not forget the fact that sweating is an essential bodily function that comes with certain benefits. Apart from maintaining body temperature, sweating also helps in eliminating body toxins. Sweating eliminates the excess salts, retains the calcium in our bones, and prevents the formation of kidney stones. Sweat contains nitrite, which acts as an antibacterial, anti-fungal on the skin and prevents sickness.
But too much of anything is not good, isn’t it? The excessive sweating we often ignore as signs of tension or nervousness could be a health condition that needs proper medical treatment. Read our other blogs on excessive sweating to understand the condition better.
