The human body is an amazing instrument. Think about all of the incredible things it does for us, without us even telling it to—breathing, beating our hearts, digesting our food, supplying us with necessary chemicals and hormones. It’s truly mind-boggling. And we found some facts that mind just blown your mind even more.
Here are 13 strange and fascinating facts about the human body that you probably never knew.
You’ll probably never take your body for granted after reading these.
1. When people blush, so does their stomach lining.
Both the human stomach and the face become red when blushing. It’s because it causes all of the capillaries in your body to widen. The increased blood flow is responsible for the red color.
2. Having your heart broken actually causes a heart condition.
It is called broken heart syndrome and it’s entirely real. The emotional stress can cause chest pain and shortness of breath similar to a heart attack. It normally resolves within a few days or weeks.
3. Human hair is pretty much indestructible.
One of the only real threats to hair is fire. Besides that, it decays at an extremely slow rate. It’s even resistant to various types of chemicals and acids.
4. Stomach acid is strong enough to burn a hole in your skin.
Individual stomachs vary in levels of acidity. However, the hydrochloric acid produced by your body is not only strong enough to break down food but in many cases, it can even bore through a piece of wood.
5. You can reduce stress by putting your thumb up to your mouth and blowing
It sounds strange, but blowing on your thumb is a great stress reliever. It works by cooling off the thumb and calming the pulse in it. This, in turn, causes your body to feel more relaxed in general.
6. Babies have more bones in their bodies than adults do.
Humans are born with at least 300 or more bones. However, many fuse together slowly over time. Adults ultimately end up with a total of 212 different bones.
7. The human eye can see at a resolution of 500 megapixels.
This estimate includes your whole field of vision spanning 180 degrees. It would take a very high-definition camera to match this. The eye is superior to most devices.
8. Your skin makes up around 16% of your body weight.
In the average adult, that means around 20 pounds or more of just skin. If you peeled it off and lined it up, it would cover an area of about 22 square feet. Now that is a lot of skin!
9. There is ten times as much bacteria in the body as there are human cells.
Bacteria are much more plentiful than actual cells. The giant microbial communities have a serious effect on health. Yet, they are still largely unstudied by scientists.
10. Our eyes are closed 10% of the time that we are awake.
This is mostly made up of the time spent blinking. A blink only lasts a split second, but we do it a lot. The average person blinks around 15 to 20 times per minute.
11. All of your blood gets filtered by your kidney 25 times per day.
It comes out to around 180 liters of blood processed daily. The average body contains seven or eight liters in total. The kidney filtration is crucial to keeping your blood healthy.
12. You are shorter at night when you go to bed.
Your height is the tallest first thing in the morning when you wake up. Over the course of the day, your spine gets compressed. There is a gelatin-like material in between your discs that act as a cushion. It moves around while you sleep.
13. You lose around half of your taste buds by age 60.
Humans begin with about 10,000 taste buds. However, due to age, the way things taste changes over time. Taste buds really only last around ten days before changing.
