One landscape produces warm sweat, the other cold sweating. So what is the difference?
What is hot sweating?
This type of sweat is also called thermoregulatory sweat. This is the natural reaction of the body that increases the body temperature of the body, which often comes from physical exertion. As the sweat evaporates from the skin, it cools the body to help prevent overheating.
When you are exercising or out on a warm day, your body gets hot, then sends a message to the hypothalamus area of your brain.
Your hypothalamus prefers to keep your body in an optimal temperature range. So to reduce heat stressIt sends signals under the spinal cord and peripheral veins (spinal cord and veins outside the brain). It stimulates sweat secretion from Malevolent Glands in your skin.
Humans consist of millions of ackrin glands, which are packed at the density of 250–550 glands per square centimeter on the palms of the feet and soles. In places where you have hair (such as face, trunk and limb), the density of ackrin glands is low.
Sweating from the eccrine glands is mostly water and salt.
What is cold sweat?
Cold sweat is also called psychological sweat. It appears when you are experiencing Tension, WorryFear or pain.
These activate the emigadala, the brain region that helps you feel emotions and react. Amygdala then activates the hypothalamus.

It also sends a message to the adrenal glands sitting above the kidney, sitting on top of the kidney to release the hormones and epinephrine hormones, which is also called Norpenephrine (also known as Noridrenaline). These hormones travel through the blood and affect a different type of sweat gland in the skin, Peak Glands.
The apocrine glands are mainly in the adjacent, breasts, face and perineum (where external genitalia). Sweat from the apocrine glands contains a lot of lipids (fat), protein, sugar and ammonia.
Sweat in the form of cold triggers ackrin And Apocrine glands, you can sweat your entire body.
What kind of fragrance is there?
Sweating yourself – whether hot or cold – does not sniff. But when bacteria feed on your skin with sweat on sweat, it produces volatile organic compounds. And this is the smell. Like blame bacteria Corinbacterium, Staphylococcus And Cutebacterium,
A small study in Japan showed stress, not exercise, unpleasant body smells were triggered in those who usually do not have the body odor.
This is probably because bacteria prefer cold sweat from the apocrine glands. It is a delicious food, filled with fat, protein and sugars.
Another study analyzed the results of 26 earlier studies involving 1,652 people. This showed that when we are frightened, we give specific smell through our sweat.
So yes, in fear and stress there is a really distinctive smell that others must warns to stay away.
In short
Warm and cold sweat do not refer to sweat temperatures. Continued fluid is always at body temperature.
