The human body is full of surprises – and much of what we think is impossible is actually completely natural.
Get ready to be amazed! These wild body facts sound like something out of a movie – but they’re absolutely real.
From glowing skin to a heart that can beat outside the body.
-
The stomach creates a fresh layer of mucus every 24 hours
-
This mucus protects against powerful stomach acid
-
Without it, the acid would start “digesting” your own stomach
Your Body Glows in the Dark
-
Humans emit faint bioluminescent light
-
It’s 1,000 times weaker than the human eye can detect
-
The glow varies in intensity throughout the day
You Have More Bacterial DNA Than Human DNA
-
Only about 43% of your cells are human
-
The rest are bacteria, viruses, and other microorganisms
-
These microbes are crucial for digestion and immune function
Your Heart Can Beat Outside Your Body
-
The heart has its own electrical impulse
-
It can continue beating for a short time after removal from the body
-
This is useful in organ donation and scientific research
You Shed Millions of Skin Cells Every Day
-
Around 30,000 to 40,000 skin cells fall off every hour
-
That adds up to nearly 4 kilograms (almost 9 pounds) of dead skin a year
-
Most household dust comes from dead skin cells
Your Nose Can Detect Over 1 Trillion Scents
-
It was once believed humans could only detect 10,000 smells
-
New research shows the nose is far more complex
-
Your sense of smell is linked to both memory and emotion
Bones Are Stronger Than Steel
-
Bone tissue is lighter than steel but five times stronger
-
A human bone can withstand up to 8,600 kg of pressure per square centimeter
-
At the same time, bones are flexible and hard to break
You Can Survive Without Many of Your Organs
-
You can live with just one kidney, one lung, 75% of your liver, and even without a spleen
-
The body is excellent at adapting and compensating
-
Modern surgery takes advantage of this resilience
