Mysterious body phenomena of humans

There are phenomena in our lives that have become so natural that few people stop and ask why. However, once they pay attention, they turn into strange issues. Let's find an answer to some of the tough questions related to our bodies below.

1. Why are hands sweating when stressed?

We know that sweat glands are located all over the body. The sweat gland is divided into two types: one that secretes substances containing fatty acids and proteins, often accompanied by the body odor called Apocrine and the Eccrine gland - mainly secreted by salt, electrolytes and water - not at all. smells.

The Eccrine gland is used by the body as a cooling system : to perspire to reduce its temperature. When we are in a stressful state, the sympathetic nervous system becomes overwhelmed. It is a system that controls the basic functions of the body such as heart rate, pupil elasticity, blushing reflexes or even body temperature.

When over-stimulated, the system raises the body's temperature and thereby stimulates the sweat glands to make your hands become 'steamy'.

2. Why are we peeing out when we're scared?

If you're too scared to pee your pants, don't be too embarrassed because it's the fault of the hemming system . This is the part of the brain that controls the " beating or running " reaction, attacking and expressing emotions, automatic functions, behavior as well as endocrine-related aspects of the body.

Bladder control is actually a sophisticated manipulation of the brain. There is an area of ​​the brain called the urination center of the brain, which is responsible for receiving information about water pressure in the bladder and making a decision to 'release' that pressure.

However, to avoid being urinated every time the bladder is full, the prefrontal cortex may send a signal that suppresses this activity.When stressed, these signals can be overwritten by electrical signals from the border system and the bladder is no longer controlled but 'self-relieved' .

3. Why are we vomiting when dizzy?

The cause of dizziness is often an intense stimulation on the vestibular apparatus in the middle ear. And somehow these signals stimulate the body to produce a vomiting reaction.

Another explanation is that when dizzy, the body mistakenly believes that we have been poisoned. And as a measure of toxic waste, the brain stimulates the stomach, causing us to vomit.

4. Why do we like to sing and sing better when taking a shower?

For many people, bathing is the most comfortable and comfortable time of the day.Along with warm water, small space, safe singing is a natural activity to help you relax.

Moreover, the sound in the bathroom has better reverberation so it makes your voice feel more good and professional. That's why many people turn into singers and like to sing chirping under their shower.

5. Why is there just one stuffy nose?

We often suffer from stuffy nose when we have a cold. But this never happens on both sides of the nose at the same time.

The reason is the rotating operation of the nose wings . Few people know that, in a certain period of time, only one side of the nose is in charge of moving most of the air.

After a few hours, the nervous system will give a 'side change' signal and so on, the wings of the nose take turns working. That's why the stuffy nose will switch back and forth between the sides of your nose.

6. Why are we hangover after being drunk?

In the morning after a night of drinking too much, we often feel dizzy, tired, tired, sensitive to light, sound . That's because alcohol has caused our body to become severely dehydrated .

At the same time, this agent also blooms blood vessels, leading to a headache. Along with that, alcohol increases the acid in the stomach, stimulates the ability of the stomach to clean itself, causing us to vomit. All create an unpleasant feeling the next day.
