When it comes to the human body, it doesn’t matter what color your skin is or where you come from…we all have one!
Remember in school when you first started learning about the human body? Yeah, the following 30 facts about the human body were probably not part of your teachers lesson plan. But, it should have been because they are super interesting!
1. The human body contains enough iron to make a three-inch long metal nail.
2. Feeling stressed or anxious? Calming music is said to lower heart rate and decrease tension, while upbeat music speeds pulse up.
3. The heart has its very own electrical system, which allows it to continue beating after it’s been removed from the body. As long as there’s an oxygen supply, it will keep pumping.
4. On an average day, the heart produces enough energy to power a truck for 20 miles.
5. Sweat stinks, right? Wrong. Body odor occurs when sweat mixes with bacteria already living on your skin.
6. If your eye was a digital camera, it would boast 576 megapixels – that translates to roughly $3,000 of Canon equipment.
7. There are over 200 bones in your body – and ¼ of those are in your feet! Foot bones that are not properly aligned can have detrimental effects to the rest of the body.
8. Female hearts beat faster than males, despite being smaller in size. While an average woman’s heart weighs around 118 grams, a man’s can weigh up to 60 grams more.
9. In your lifetime, you’ll produce enough saliva to fill two swimming pools.
10. Did you know that at this very moment you’re shedding? Adult humans shed up to 600,000 particles of skin every hour, or 1.5 pounds per year. And we thought our dogs were bad …
11. You know that moment in cartoons when someone gets an idea and a light bulb appears over their head? Turns out, that’s not so far-fetched after all. When awake, an adult brain produces enough electricity to power a small light bulb.
12. The human nose can remember up to 50,000 scents. Just hearing phrases like “new car,” “bookstore,” or “grandma’s house” can awaken your memory.
13. Average adults excrete up to 1.42 liters of urine per day.
14. Tiny mites known as demodex live in the hair follicles of our eyelashes, eyebrows, and nose hairs. They don’t like light, but when it’s dark, they leave the follicles to explore the skin of your face. I know, I know, it sounds like a bad science fiction movie, but these little guys are super important – they eat dead skin cells and oil and help keep you blemish-free. Thanks, demodex!
15. The strongest bone in the body is the masseter, otherwise known as the jaw muscle.
16. “If you shave, the hair will grow back thicker and darker!” We’ve all heard this a hundred times, but there’s actually no scientific evidence to support the claim.
17. Not getting enough sleep can be detrimental to your health, and even reduce your life expectancy.
18. The cartilage in our ears and noses never stops growing.
19. In an average lifespan, the heart pumps enough blood to fill 200 train cars.
20. Adults have only 206 bones, while babies have 270. What happened to those 64 bones? By puberty, they have fused with their neighbors. “Growing pains” isn’t just a saying!
21. 75 – 90% of the dust in your home comes from dead skin cells. If that doesn’t make you want to break out the vacuum, I don’t know what will …
22. It’s said that women with large bottoms have a higher resistance to chronic illnesses. This doesn’t mean you should try to increase the size of your bottom, however – you can be just as a healthy at a thinner weight. Although women often feel pressure to be a certain size, our bodies are all different, and can be healthiest at very different weights. Just look at Marilyn rocking the size 12!
23. Your brain keeps developing well into your 40s. Keep it limber by doing plenty of reading and problem-solving.
24. The “tongue print” is just as unique as a fingerprint.
25. There are 100,000 miles of blood vessels in an adult human body. End to end, they could stretch from Virginia to California 33 times.
26. Your eye can detect up to 10 million different colors. Finding the words to describe them is up to you.
27. The brain uses 20% of the body’s oxygen and blood supply, daily.
28. There are 7 octillion atoms in each and every human. That’s a 7 followed by 27 zeros, which looks like this: 7,000,000,000,000,000,000,000,000,000. That’s right, we typed it so you don’t have to.
29. With training and exercise, some people are able to hold their breath for several minutes at a time. It takes years of practice and isn’t something that should be tried at home.
30. Our body uses up to 200 muscles each and every time we take a step. Walking is definitely a form of exercise!
