Even though you’re around human bodies all day (after all, you have one of your very own), you probably don’t know everything there is to know about them. Each of our bodies are a miracle; it’s amazing they work the way they do, day in and day out. If you thought what our bodies could do before, once you read this list of insane facts about the human body, you’ll be in awe. Never take your own body for granted, because some of the things it can do are mind-blowing.
1.) The average person produces enough saliva in their lifetime to fill 2 swimming pools.
2.) Every 60 seconds, your red blood cells do a complete circuit of your body.
3.) Sometimes, when you have to pee, you can visibly see that your bladder is bigger.
4.) Most babies are born with blue eyes; exposure to UV light brings out their true color.
5.) Most westerners consume 50 tons of food and 50,000 liters of liquid in their lifetime.
6.) It can take your finger and toenails 1/2 a year to grow an entirely new nail (from base to tip).
7.) The muscles that control your eyes contract about 100,000 times a day (that’s the equivalent of giving your legs a workout by walking 50 miles).
8.) Over the course of your lifetime, you’ll shed about 40lbs of skin.
9.) Your brain uses about 20% of your oxygen and caloric intake.
10.) In each kidney, there are 1 million filters that clean around 1.3 liters of blood every minute and push out close to 1.5 liters of urine every day.
11.) Ovaries contain over 500,000 eggs, but only about 400 get the opportunity to create life.
12.) Everyone has a completely unique smell (except for twins).
13.) Why doesn’t your stomach digest itself? That’s because your stomach cells are created faster than they can be destroyed.
14.) You have about half-a-million sweat glands that produce about a pint of sweat daily.
15.) Humans are extremely visual; 90% of the information we gather from our surroundings is from our eyesight.
16.) It’s nearly impossible to tickle yourself.
17.) Baby foreskin is often used as a skin graft for burn victims.
18.) Your bones, pound for pound, are 4x stronger than concrete.
19.) Your skin is the largest organ in your body; if an adult male’s skin were to be stretched out, it would cover 20 square feet.
20.) In order to taste something, our saliva needs to dissolve it (try drying off your tongue and tasting something).
21.) Men produce about 10 million new sperm daily (approximately enough to repopulate the entire planet in 6 months).
22.) In just 30 minutes, your body can produce enough heat to boil half a gallon of water.
23.) There are more than 300,000,000 capillaries in your lungs and if they were stretched out tip to tip they would reach approximately the distance between Atlanta and LA.
24.) Frequent dreams are correlated with having a higher IQ.
25.) You’ll be about 1cm shorter when you go to bed at night compared to when you wake up in the morning. Your cartilage in your spine slowly compresses throughout the day.
