The skin is, without a doubt, a very important part of your body. It’s actually the largest organ in the human body. But despite that fact, it still remains a bit of a mysterious organ. Of course, everybody knows that it can change its color, texture, and appearance, like after sunbathing, for example. But some other reactions, such as blushing or getting goosebumps, can give us a deeper understanding of how our body works.
In order to learn more about the skin, our team carried out a quick search on specialized websites. And we’re happy to say that we found answers to many questions about all the things our skin does every day and we can’t stop thinking about it.
1. Our skin is completely renewed every month.
You probably already know that your skin is made up of billions of cells, so there’s no secret there. However, from that extremely high number, about 30,000 to 40,000 cells are lost in the form of flakes. And that’s just in one minute. So basically, if you were to add up the weight of the skin you lost over the last 4 and a half years, you’d end up with about 40 pounds of skin flakes! Of course, you hardly even notice this in your daily life. Dead skin just falls off without making a sound or leaving a trace. It just becomes dust, which makes up a lot of what you sweep up when you’re cleaning the house.
This may lead you to wonder what happens when we lose that skin. As it turns out, the skin is all about regeneration. In other words, most people just have completely renewed skin after 2 weeks to a month. That also means that most of the skin that is visible to the naked eye is actually ready to be shed. If you find this to be a bit creepy, just think about the fact that shedding so much skin is also what allows our wounds to heal so quickly. On the downside, that’s also why our tans don’t last very long…
2. Why we blush
Blushing is a natural response that we cannot control. It’s the way in which our bodies react without us being able to do anything to prevent it. You might even say that the more we want to hide that we’re ashamed of something, the more flush we become. When we experience shame or regret, the adrenaline in the body increases, the heart beats faster, and one breathes heavily. The blood vessels expand so that the extra blood being pumped can flow through faster. Of course, in your face, it’s veins in our cheeks that are expanding, and that’s what makes our face suddenly, and much to our regret, hopelessly red.
In a way, when you’re blushing, you’re giving away that you acknowledge that you’ve done something you weren’t supposed to do and that you feel ashamed of it. Blushing can also be an involuntary way of saying you’re sorry when you’ve done something society doesn’t agree with.
3. Why some people have freckles
Melanin is the main player here. Freckles are the parts of your skin with a higher concentration of melanin that isn’t distributed evenly, but instead, in small groups. However, the mechanism remains the same: the areas of the skin with a higher concentration of melanin become active when exposed to sunlight. That’s also why some freckles often appear in the summer and then disappear during the winter.
Interestingly, freckles seem to appear faster than a regular tan mostly because they’re grouped in small areas of the body, making them more noticeable in contrast. But melanin is actually active in all types of skin at all times.
