15 Amazing Facts Of The Incredibly Amazing Sweat

Sweating is the signature of workouts and strenuous exercising while being a symbol of being athletic and having a good health mentality. Sweat serves significant roles in human and mammalian anatomical functions. It’s not normally something you’d be thankful for, but once you begin to dwell and explore you may start to realize how lucky we are to have the ability to sweat.

1. People sweat from their pores as a self-cooling system; as the moisture released from the pores evaporates heat is moved away from you as your body tries to maintain the 98.6 degrees Fahrenheit. The heat

of evaporation is the amount of energy required for a liquid (sweat in this example) to transform into a vapor, and therefore escape with the heat as well.
2. The heat of evaporation is also why that in a humid environment after a shower, you don’t feel as cold. Because the water ‘eats’ the energy from your body, it is important that you do not go outside in the cold wet for your body temperature is more vulnerable. This knowledge is also why I dry myself off inside the shower; instead of stepping out first, I dry the water away from my body so that it cannot evaporate and steal my heat energy. There is also a higher concentration of water within the shower rather than inside the bathroom, making it ideal to dry off before even stepping out.
3. Some animals lack an abundance of sweat glands, which creates difficulty for to stay cool and regulate their core temperature. The lion can exemplify this, as they have very few sweat glands and are therefore often seen lying around and about.
4. And contrary to popular belief, dogs do in fact have sweat glands; sweating is just simply not their primary system of cooling. As dogs not have many sweat glands, they do have them on their paws.
5. However, the main process by which dogs cool themselves down is by panting. The dog’s tongue also doesn’t contain sweat glands, but instead house saliva glands that cool as air surfs over them. They can also dilate the blood vessels near the surface of the face and help cool the blood within the dog.
6. Unlike man, the dog’s healthy internal temperature is between 100.5 and 102.5 degrees Fahrenheit
7. Sweat glands are commonly found connected to nerves and inside the dermis layer of the skin which an outer layer of skin.
8. There are different kinds of sweat glands for different parts of your body that secrete different types of sweats that are made from different

concentrations and chemical compounds
9. Apocrine glands are found in the pits of your body such as the armpit. They are commonly found it areas with the most hair follicles such as the armpit, groin and scalp. This gland releases sweat composed proteins, lipids (fat) and steroids. This provides great habiting grounds for bacteria to feast on.
10. Eccrine glands are commonly found on your feet, hands, and forehand; they secrete a relatively odorless sweat laced with sodium (salts). Though the secretion itself is odorless, when eaten by the bacteria on your skin, it produces the bad smell.
11. Lastly the sebaceous glands are microscopic glands found on the face and scalp that produce an oily liquid. This substance contains fats and cellular debris and coats the surface of your skin with a waterproof layer and is called sebum.
12. Every human on earth has around 2.6 million of these glands on their bodies.
13. Because sweating has to travel through multiple layers of the skin. So as the sweat exits the pores of the body dirt and chemicals are pushed out of the pores in your skin. Such as various sodium, fats, an oil. Therefore can clean out the skin and help your relative skin health by opening the pores.
14. Some forms of naturally occurring antibiotics are also contained in your sweat which when coming with contact with the bacteria on your skin kills them and excretes smelly odors. In addition to this; fats, proteins and salts can also produce an unpleasant smell. The salty taste is what is left of the sweat when it dries/evaporates off of your body. In addition, the bacteria may also eat some of the ingredients of your sweat and will then in turn produce a smelly substance.
15. People that sweat often also sweat healthier. What happens is that in the beginning, the sweat is very fatty and oily. As people continue to sweat more often, the composition of the perspiration clears up and becomes less oily and gross like.
