5 superhuman 'abilities' that you have never realized

Looks like we're underestimating ourselves, guys!

The superpowers of themselves that people do not expect

You know, our bodies are actually more magical than you think. We have "superpowers" and still use them every day, but never realize it.

1. You really "see" your own hand in the dark

Try it out. Try entering a dark room - very dark. Then raise your hand and wave in front of you. You will see things like the image below.

Even in the dark, you can still see your own hands.

Surprise? Actually, it is not very mysterious. According to a study by the University of Rochester (USA), most of the images we "see" everyday do not come from the eyes, but because of what the brain "wants" us to see, based on sensory information. Collected.

But this does not mean that we imagine the hand shape. In the experiment, the researchers placed an additional sensor, which allowed the candidates to track eye movements. As a result, their eyes move in the same direction as the hand movement, just like how they look when there is light.

Experts say that even when we can't see, the brain continues to receive signals from parts of the body, which in turn helps us really "see" what the brain wants to see.

2. You can distinguish hot water and cold water . by ear

Try this again. Please guess 2 sounds below - where is the hot water or cold water!

You may have guessed it right: the first sound is cold water, and the other is hot water. According to the experiment of a company in the UK, up to 96% of respondents are correct guesses.

Human ears can hear the difference in molecular speed.

In fact, this superpower is also . usually. Experts explain that human ears can hear the difference in molecular speed.

In it, cold water has a slower molecular transfer rate than hot water, so the density of denser molecules and sound when pouring are also different.

The hotter the water, the more sparse the molecular density.

However, none of us seem to notice this special ability.

3. You can smell other people's immune systems

Have you ever heard the phrase "smell of old people" ? It is a phrase many people use to indicate an unmistakable smell when exposed to the elderly.

However, scientists say that this smell is not really for the elderly, but can appear in anyone, because it is the smell . weakened immune system.

Humans can smell the weakened immune system.

To verify this, the researchers conducted a lipopolysaccharide injection test - a toxin that temporarily suppresses the body's immune system. After that, they collected sweat samples with the candidates, then gave it to another group to smell and evaluate.

Sweat of people with weak immune systems is considered to be more unpleasant than normal people.

The results showed that the sweat patterns of people with weak immune systems were considered more unpleasant. This proves that our bodies produce scents that are relatively . hard to smell to warn others when we are ill, to prevent the risk of transmission to the community.

4. We become "super-hearing" when . in the water

The maximum human hearing threshold is 20,000 Hz, which can be said to be very catastrophic if compared to other animals. Dogs can hear sounds with a frequency of 45,000 Hz. This number in bat species is 110,000.

When underwater, your hearing ability greatly increases.

But can you believe it, just go to the water, you have activated an "esper" in your ear, allowing you to hear the sound up to . 200,000 Hz. Why is . so magical? That's because we can hear with . bones.

Under the water, you not only hear with ears but also hear with bones.

The experts explain, we hear the sound is due to air movement, creating vibrations in the ear canal, cochlea, eardrum, small bones .

However, when there is no air, the sound will skip the whole process through the mastoid bone - the bone behind the ear. This is also the principle that hearing aids are currently applied. Now when you dive into the water, listen carefully to see what you see!

5. Your skin has a special ability to sniff and recover with a very fast speed

German scientists have recently discovered that some cells that help the nose "sniff" actually exist on human skin. This means that our skin can really . sniff.

The skin also sniffed .

To validate this, the researchers tried skin cells in contact with sandalwood essential oil - an essential oil with a strong odor.

The results showed that irritated skin cells split with an increase of 32%. At the same time, new cells will "scour" the area for skin damage to treat.

Speed ​​to recover normal wounds (upper) and after "sniffing" the skin (bottom).

However, in order for the skin to "smell", it is necessary to have a concentration of 1000% greater than the required concentration for the nose to feel. That is, to heal the wound quickly, you may be . deaf because the smell is too strong.
