Top 8 body parts that hide many interesting things that even you yourself don't know

The human body is a complex machine and it can be very time consuming to understand all its secrets. Researchers have tried to uncover the surface of many problems but not all secrets have been deciphered. For example, the human consciousness and subconscious mind is still a mystery.

Here are 8 body parts that can be considered "smooth" to everyone, but it turns out that they still hide many mysteries that not everyone knows.

Mysteries about human body parts

1. Human skin looks very different under UV rays

Used medicinally, exposing the skin to UV light to detect bacterial and fungal infections as well as pigmentation abnormalities. Under UV light, healthy skin will glow with vitality without illumination. It can appear white spots when the skin is thick, yellow spots where the skin is oily, and purple patches where the skin is dry.

2. Your brain "freezes" when it detects a sudden drop in temperature

Whenever the temperature on the roof of the mouth drops, the brain takes action to prevent the body from freezing to death. In other words, the brain will raise blood pressure as a warning to the body.

And there is also the mechanism of "brain freeze" when eating too much ice cream at once.

3. Stress can cause the heart to change size and shape

Takotsubo syndrome is a condition that causes the left ventricle of the heart to change shape and not be able to pump blood properly. During short-term stress, 2 molecules released during stress and depression can affect the functioning of heart muscle cells, leading to temporary weakness.

4. Dancing increases your brain power and white matter

White matter is the tissue that connects nerve cells to each other, allowing communication to move continuously between areas of gray matter and the rest of the body. As we age, white matter declines, leading to symptoms like memory loss and difficulty solving problems.

But research has shown that dancing increases white matter in the brain, which boosts cognitive function and keeps the brain functioning properly.

5. Gut bacteria can affect your mood

The gut microbiome, which is an ecosystem made up of many different types of bacteria, has co-evolved with humans to benefit both the host and the bacteria.

This microbe is known to have an effect on the human psyche because it contains a large number of chemicals used by our neurons to communicate and regulate mood, such as dopamine and serotonin. Speaking of which, 95% of the body's supply of serotonin is produced in the gut.

6. Modern humans' brains are smaller than our ancestors'

The brain is smaller now than it was 3,000 years ago. Before assuming this is bad news, remember that there is a correlation between body size and brain. So as the body gets smaller, so does the brain.

7. The brain has the ability to distort memories

We all have a friend who tells the same story every time with different details. The reason why they do so is because their memory has been distorted. We often think of our brain as a machine that stores and organizes memories like a camera or a tape recorder.

While in fact, many studies have concluded that memories, even our most cherished ones, can be distorted every day. False memories can affect anyone, regardless of whether the memory is trivial or life-changing.

8. Ears and nose sag over time

As people age, the body shrinks, but the nose and ears get bigger.

As people age, the body shrinks, but the nose and ears continue to enlarge. This happens because our skin starts to lose its elasticity and cannot hold the support it used to. The nose and ears are no exception.

These crystalline bodies change size as we age, but not because we are growing - it is because of gravity.
