There’s a lot we think we know about the human body. We learn about it in school, we see it in movies and on TV, and we read about it in books. But how much of what we think we know is actually true? 

It turns out, quite a lot of it is actually myths! In this article, we’ll dispel some of the most popular myths about the human body that you probably believe. we’ll set the record straight on 5 popular myths about the human body!

 

1. We only use 10% of our brain

 

You might have heard that we only use 10% of our brain. This urban legend has been around for years, and it's still circulating today. But where did it come from? And is there any truth to it?

 

Let's start with the origins of the myth. It's thought that the 10% figure first came from a self-help book published in the early 1900s. The book, called "The secret of success," claimed that humans only use 10% of their mental capacity. This claim was based on the observation that people only use a small portion of their physical capacity, so it must be true for mental capacity as well.

 

However, there is no scientific evidence to support this claim. In fact, brain imaging studies have shown that we use 100% of our brain. So where did this urban legend come from? It's likely a misunderstanding of the fact that we only use a small portion of our brain at any given time. The rest of the brain is active, but not being used for conscious thought. This doesn't mean that we only use 10% of our brain power, it just means that we only use a small portion of our brain at any given time.

 

So there you have it! The 10% brain myth is just that-a myth.

 

2. Humans have more than 5 senses

 

You might think that humans only have five senses - sight, sound, smell, taste, and touch. But there's actually a lot more to it than that. Humans have a plethora of other senses that help us interact with the world around us.

 

For example, we have proprioception, which is the sense of where our body parts are in space. We also have nociception, which is the sense of pain. And we have the sense of balance, which helps us keep upright.

 

There are actually many different senses that humans have, and scientists are still learning more about them all the time. So next time you think about the five senses, remember that there's a lot more to it than meets the eye.


3. Shaving doesn't make hair grow back thicker

 

There is a common misconception that shaving causes hair to grow back thicker. But this simply isn't true. Hair grows back the same regardless of whether it's shaved or not. The only difference is that shaved hair appears to be thicker because the blunt end of the hair shaft is exposed. So if you're looking to thicken up your hair, shaving is not the way to go.


4. Cracking your knuckles gives you arthritis

 

It is a common belief that cracking your knuckles gives you arthritis. However, there is no scientific evidence to support this claim. In fact, there is no evidence that knuckle cracking causes any kind of damage to the joints.

 

So why do people believe this? It is likely because they mistake the sound of cracking joints for the sound of bones rubbing together. This is not the case, as the sound of cracking joints is actually caused by bubbles bursting in the synovial fluid (the fluid that lubricates the joints).

 

So there you have it. Cracking your knuckles does not cause arthritis.

 

5. You have to eat 8 glasses of water a day


There's no hard and fast rule that you have to drink eight glasses of water a day. However, it's a good idea to drink plenty of fluids to stay hydrated. Depending on your activity level, climate, and other factors, you may need more or less water than usual.

 

If you're looking to up your water intake, there are a few simple ways to do it. Drink a glass of water first thing in the morning, carry a water bottle with you throughout the day, and make sure to drink water with every meal. You can also add some flavour to your water by infusing it with fruits or herbs.
