Why Do We Sweat- Know it here
We all know what sweat is, and when we hear the word, we immediately get a negative feeling about it. Sadly sweat has a bad reputation. People are often disgusted when it appears or is visible on other people’s clothes or bodies. You may also be blaming sweat for staining your white or light colored clothes!
But have you ever wondered why do we sweat? Actually, the negative feelings we all have towards sweat is misguided as in reality, we need sweat to keep healthy. Whenever your body temperature rises for any reason at all, whether it’s because you’re doing strenuous activities such as working out or the temperature of the environment is rising, then you begin to sweat.
This is your body’s way of cooling down, but not only when the sweat just drips off your body. For you to be able to cool down, the sweat must evaporate right off of your skin, turning into a gas, which gives you the cooling effect.
Interesting, isn’t it? In this article, you will learn all about sweat, the benefits and the answer to the question, why do we sweat?
The Science of Sweating
As previously stated, when you sweat and the sweat evaporates into the air, your body is able to cool down by removing excess heat. The whole process of sweating can actually be explained through a physic principle. Let’s elaborate.
Water can only by convert into a gas when a specific amount if heat (called the heat of vaporization) is applied to it. The energy of the heat speeds up the water molecules so that they can break-out from the liquid and go into the air.
Of course, not all of your sweat evaporates off your body. In fact, most of it either runs or drips off your skin or before it can even evaporate, you’ve already wiped it off with a towel.
Also, your sweat doesn’t totally eliminate all the heat energy your body produces. Some if it is either lost through the respiratory surfaces of your own lungs or radiated straight into the air from the surface of your skin.
The main element which affects the evaporation rate is the humidity of the air in your environment. When the air around you is humid, it means that water vapor is already present, probably abundantly, and so the air cannot take any more water molecules. This is why your sweat won’t evaporate and cool you down as well as if the air around you is dry.
Not all components of your sweat evaporate into the air, only the water. So when the water is gone, the salts – made up of potassium, sodium, and chloride are left behind on the surface of your skin, which is why it tastes salty when you’re sweaty. When you are sweating a lot, you have to remember to hydrate a lot too because when too many amounts of water and salt are lost from your body, it can lead to detrimental effects on your health.
Now that you have a better idea of sweat, let’s look into the different benefits of this commonly misunderstood body product.
The Benefits of Sweating
Before we answer your question of why do we sweat, let’s take a look at the different benefits of sweating. While a lot of people are put off by the whole concept of sweat and sweating, it actually has a lot of benefits related to your health and even beauty. Those benefits include:
Regulate Your Body Temperature
To remain healthy and comfortable, your body would have to maintain a certain temperature and once your body temperature starts to rise, your body may be at risk for overheating if you don’t cool down.
Sweating is one of the ways your body cools itself down. This is one of the main benefits of sweat since when your brain feels that your body is beginning to heat up, and then it starts to stimulate your sweat glands to produce sweat.
Detoxify Your Body
Not only has your health benefited from detoxification, but your beauty and vitality as well. Sweat helps you eject unwanted toxins from your body. This boosts your immune functions and it also helps you avoid getting diseases which are related to overload of toxins.
Eliminate Some Bacteria and Viruses
Some bacteria and viruses are unable to survive in temperatures over 98.6˚F. Sweating helps in eliminating these viruses and bacteria even if you didn’t know that they had been present in your body!
Clean Your Pores
Since the sweat which is produced by your body is released through the pores of your skin, it also cleanses your pores, which in turn, effectively removes any acne and blackheads.
These benefits are all good for your health and your beauty so don’t be too bothered when you start to sweat – it’s actually a good thing! Now that you know the benefits, let’s move on to answering the main question of this article in the next section.
So… Why Do We Sweat?
Did you know that an average person has around 2-4 million sweat glands on the body. These sweat glands can be classified into two types – apocrine and eccrine. These glands are responsible for producting sweat when out body heats up.
The apocrine glands are located in your underarm and groin. These glands can be stimulated by the body’s temperature as well as feelings of anxiety and stress or hormones which fluctuate. These glands also produce bacteria which actually breaks down the sweat, which in turn causes body odor to occur.
The eccrine glands, on the other hand, are found all over the body, which is why w have thousands of them. They are responsible for adjusting the body’s overall temperature. When your body temperature increases, a signal is sent to your nervous system to start stimulating the eccrine glands to produce and release sweat.
So the simplest answer to the question of why do we sweat is so that our body doesn’t overheat and it would have an outlet or some way to cool down despite environmental conditions. So the next time you sweat – don’t sweat it! It’s your body’s way of regulating your temperature, which is actually beneficial to you.
So the best thing you can do is hydrate and put on some deodorant especially when you know you will be doing any particularly strenuous activities or the environment you’ll be staying in is hot or humid.
