Why is sweating effective




















Sweat marks and the stench could leave you in a pit of embarrassment but could also be beneficial to your health. The almost 1 liter of sweat our bodies produce per day can strengthen our immune system and give us healthy-looking skin.

Sweating also increases the blood circulation in the body. The drips of perspiration is proof our body has a built-in mechanism for keeping cool, which can help open up and unclog pores. The droplets consist primarily of water, as well as concentrations of sodium and chloride, and potassium to an extent, according to HowStuffWorks.

Exercising increases the level of the feel-good endorphin hormones that are naturally released during physical activity. A study published in the journal Biology Letters found group workouts actually increase endorphin levels and cause less pain for those who work out together than those who train alone.

They would probably be moving around a little bit to begin with, but then the warmer this is, the more energy here, they'll bump into these molecules. So let's say this guy bumps into that, then he'll bump over there , so that energy, this bumping energy, or this kinetic energy, well, some of it will be transferred, or you could even say some of that temperature, some of that heat will be transferred to these water molecules.

But the important thing to remember is this is a really kind of crazy thing, they're all bumping into eachother and rotating in all sorts of crazy ways. They will have an average kinetic energy, which we perceive as temperature, but this one might be going really, really, really fast in that direction, while this one might be going really, really, really slow, this one might be going really really really fast in that direction this one might be going really slow in this direction So the thing to think about is, given that you have all of this variation in the energy of each of these particles, which of these are most likely to escape, to actually evaporate?

And to think about evaporation, you just have to think about that most water molecules or the water molecules that are in that droplet they do have an attraction to eachother, we call those hydrogen bonds. They do have an attraction to eachother, that's why a droplet kind of sticks together. But if one of these molecules is moving fast enough and if it's moving in the right direction it has a higher probability of being able to escape, being able to actually escape that droplet.

And the process of these molecules actually escaping, that's what we refer to as evaporation. If a molecule has enough energy it will escape this, escape the bonds of the other water molecules, and just evaporate into the air. But we still haven't fully answered our question. So let's say that this is one that has evaporated, it has fully escaped. Why would that actually cool down this entire system? Why would it cool down the droplet and essentially give it more capability to accept more energy from the skin?

Well, we just said the ones that have the highest energy are the ones that are most likely to escape, the ones that have the highest kinetic energy. So if you have a bunch of stuff, some are fast, some are slow, some are vibrating a lot, vibrating less but the ones that have a high kinetic energy are the most likely to escape, what happens when they escape? Well then the average kinetic energy will go down.

Here's everything you ever wanted to know or maybe didn't know you wanted to know about how sweat works, including why we sweat when we're hot, as well as why we sweat even when we're not. Sweating gets a bad rap, and, sure, it is sort of gross. But sweating is vitally important for body temperature regulation and your overall health. A person's internal body temperature generally hangs around 98 degrees Fahrenheit. There's flexibility here, but if your body gets too hot, whether it's due to the temperature outside, being physically active or having a fever, bad things can happen — for instance, heat stroke.

Fortunately, your body has very sophisticated mechanisms for sensing and regulating body temperature. As soon as your body's internal temperature starts rising, your hypothalamus a small region in your brain tells eccrine sweat glands distributed all over your body that it's time to start cooling you down by producing sweat. Cooling down, however, isn't as easy as this sweat just dripping off of you.

Some of this sweat has to evaporate off of your skin for this process to actually work. That's because cooling your body via sweating relies on a principle of physics called "heat of vaporization. It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.

The other trade off here, though, is that you also lose water as you sweat — and water is critically important for just about every organ in your body. This means that when you're sweating, you also need to make sure you're drinking plenty of water so you can replace the water you lose with water you can use.
