Strange body reactions make it difficult for you to understand

Waking up early after a drunken night, wrinkled hands when meeting water . are secrets about our bodies that not everyone can explain.

People are the most complex creatures on the planet, so much so that we sometimes cannot explain ourselves. From physiological characteristics to daily habits, unconditional actions, reactions . seemingly simple but all have to make the researcher 'blow up the brain' and not yet find an answer.

Here are some weird actions of our bodies that have been explained by scientists.

1. My own voice when listening on the recorder

There is a truth that we all encounter - it is very strange to hear our voice through voice recorders. Most will ask the same question: 'Why is my voice so bad when recording?'

The question everyone will ask when listening to the recording of his voice: "Is this my voice?"

The answer has been found by scientists. Accordingly, the voice in the new recorder is our true voice that others feel when we hear it.

Normally, the sound of the voice that we hear ourselves has been somewhat distorted by the brain, deceiving and helping us feel . happy.

Machines don't lie, so the voice in the recorder is your real voice.

Specifically, in the instinct of each human being, the brain self-conventions that men must have a loud, warm, deep voice while women will be more attractive with a soft, high-pitched voice.

Therefore, when speaking or singing, the waves transmitted from the larynx to the brain will be 'distorted' somewhat, making us feel comfortable and comfortable about our voices all the time.

Obviously, the ear does not always hear correctly.

In addition, another reason that your voice is worse when recording is because the sound waves are transmitted to the air will meet different obstacles. Therefore, the sound quality is not as good as when it is transmitted directly in your body to the brain.

2. Hand skin wrinkles when meeting water

Have you ever noticed, when taking a dip in the pool water for a long time or simply when bathing, your hand skin suddenly becomes wrinkled? Surely we all have encountered this situation but perhaps, not many people can understand the underlying cause of the phenomenon.

According to biologists, this is actually an evolutionary feature of human ancestors since ancient times to adapt to life in wet places.

Scientists often compare the wrinkles in the hands when wet as well as the trenches created on bicycle tires. Specifically, this feature helps increase the contact surface of the hand when touching other objects, thereby increasing friction, grip for the hands.

There was a great resemblance between wrinkled skin and grooves on bicycle tires.

Thus, from millions of years ago, when human development level was limited, wrinkled skin was an expression to support better survival.

Wrinkled skin helps our ancestors to hold and grasp weapons more easily when faced with evil beasts.

Especially for ancient people living in wet lands, wrinkled skin will help them to hold, hold firmer weapons during hunting or simply protect themselves from evil beasts.

3. Urinate more when it's cold

Few people notice that, when the weather gets cold, people tend to urinate more often. What is the cause of the reaction?

The answer lies in the body's mechanism of action in cold weather. When the outside temperature decreases, all parts react in the direction of conserving energy and body temperature.

Inside the body, blood moves less to distant parts like the heart, gathering some important organs to keep warm, called vasoconstriction. The inevitable consequence is that blood pressure will rise higher than normal.

To balance the body, the kidneys work harder to pull water out of the organs, reducing pressure on the walls of the vessels. This water will be stored in the bladder with greater volume than usual and therefore, we will urinate more.

4. Wake up very early after a drunken night

We often think after a drunken night, people will sleep very deeply and wake up late because then, parts of the body will work to eliminate the poison in the alcohol.

However, the truth is not as it appears to be. Almost everyone who has ever been drunk will experience the feeling of waking up in the night very uncomfortable right after drinking.

At first, alcohol makes us sleep easier .

In fact, in the first half of sleep, chemicals in alcohol will make you fall asleep faster than usual. At that time, the liver will work very hard to remove ethanol in alcohol.

During that time, people slept very well and did not even know what heaven and earth were. However, immediately after this period, the 'alcohol recovery effect' appears.

. but then wake up in the middle of the night and make it impossible to sleep again.

The chemicals in alcohol, especially ethanol, have a negative effect on the balance of REM sleep (rapid eye waking) of the body. Therefore, in the second half of sleep, alcohol stimulates hormones in the body, making it easier to wake up and when awake is awake, it is difficult to return to sleep as before.
