20 FACTS ABOUT THE HUMAN BODY. WHICH IS USEFUL FOR EVERYONE.
BREATHING?
As you breathe, most of the air goes in and out of one side of the nostril. After every few hours, the workload shifts to the other side of the nostril.
THE FASTEST SENSE?
Hearing is the fastest human sense. Once a sound wave reaches your ear, your brain can recognize it in just 0.05 seconds, which is 10 times faster than the blink of an eye.
ELBOW?
Try to pinch your elbow skin, and it won't hurt you because it is the only skin part of the human body that doesn't hurt.
AMYGDALA?
'Amygdala' is the part of the human brain that controls fear. If you remove it, you will lose any sense of fear.
EARS?
The right ear is better for hearing speech, and the left ear is better for hearing music.
BRAIN?
Half of the human brain can be removed without affecting memory or personality. It's called HEMISPHERECTOMY.
YOUR TEARS?
The Lacrimal Punctum is a small hole in your eyelids that drains your tears to your nose. It's the reason why you get a runny nose after crying.
SHRUNKEN BRAIN?
Multiple research studies revealed that the brains of people with severe alcohol intake are smaller and lighter than the brains of people who do not drink alcohol.
CORNEA?
The only part of the human body that has no blood supply is the CORNEA in the eye. It gets Oxygen directly from the air.
WHY DO WE HICCUP?
A membrane (Diaphragm) between our chest and abdomen moves downward and upward when we inhale and exhale. This membrane compresses due to the acidic body or chili's sticking in our food, and a strange sound is produced. This is called a hiccup. Drinking water reduces acidic matter, which results in stopping hiccups.
SHIVERING IN BABIES?
Babies do not shiver when they are cold, as babies have more fat that keeps them warm instead. If you see a baby shivering, they need to be fed immediately because it indicates low blood sugar in them.
MEMORIES OF THE BRAIN?
The human brain naturally remembers more negative memories than positive ones.
PRESSURE ON THE SPINE?
Laughing and coughing create more pressure on the spine than walking or standing.
THE UNSMILING DISORDER?
There is a rare neurological condition called Moebius syndrome, which primarily affects and paralyzes the facial muscles that control the expressions such as smiles and laughter. Under this condition, the affected person can not smile and laugh.
SNEEZE?
If you try to suppress a sneeze, it could rupture blood vessels in your head or neck, and you can die.
HALF ASLEEP?
We can't sleep in a new place comfortably because our brain is trying to protect us. Many animals sleep using their half brain, while the other half of brain stays alert to possible dangers. It is called the first-night effect in humans because our body puts us in a strange, half-asleep/half-awake state when we sleep in an unfamiliar environment.
BRUSHING OF LIPS?
Brush your lips instead of applying 'lip balm' because brushing your lips scrubs dead skin and increases the blood flow.
WOMEN`S SENSES?
Women have better senses of smell and taste. Women usually have more taste buds than men.
MOSQUITO BITE?
Press a hot spoon onto the spot of the mosquito bite. The heat will destroy the reaction, and itching will stop.
TICKLING?
When someone tickles you, the laughter is a panic response. That's why you can't tickle yourself, as your body senses any real danger.
