When you have three doubts and

After casually clicking on this article

Why don't you vote first

Sheng Xia, we always talk about relying on ice products to "survive"

But have you ever thought about it occasionally

Can these really cool down and relieve heat?

first

Let's learn about the Thermoregulation of the human body

As a Warm-blooded

Thermoregulation of human body

As an 'automatic control system'

When stimulated by internal and external environmental temperatures

Cerebral cortex and hypothalamus Thermoregulation center

Start the activity immediately

Regulating heat production and dissipation processes through nerves, bodily fluids, etc

In order to maintain

Dynamic equilibrium of heat generation and dissipation

Thermoregulation of human body/

Among them, the heat dissipation of the human body

Depends on the temperature difference between the body surface and the outside world

When the ambient temperature increases

The temperature difference between the human body and the outside world is relatively small

Even below the external temperature

The heat dissipation process will be hindered

At this point, skin blood vessels will dilate

To increase blood flow

Raise body surface temperature

To promote sweat evaporation and achieve heat dissipation

ask

That's right, so I eat ice cream to help myself cool down, isn't it?

In fact

Ice cream or cold drinks are not direct

Watering out the 'small stove' inside the body

The instant coolness felt after consuming ice products

Actually, it's just that after they enter the mouth and esophagus

Stimulating capillaries

Causing a decrease in local temperature

Other parts of the human body

It will not cause significant temperature changes as a result

After entering the stomach

Temperature of surrounding organs

It will soon cause the freezing effect to disappear

What you may not even expect is

If a large amount of ice cream and cold drinks are consumed in a short period of time

Entering the body

Not only will it be to a certain extent

Reduce the speed of human blood circulation

And it also 'deceives' the nervous system inside the body

Convey the feeling of 'I'm cool'

To suppress sweating and regulate body temperature

Normal response

Instead, it causes heat to accumulate in the body

Make people even hotter

Even more so

Cold drinks can also stimulate the gastrointestinal tract

Causing gastrointestinal dysfunction

Causing abdominal pain or diarrhea

in addition

Ice cream and cold drinks often have high sugar content

The process of breaking down sugar in the human body naturally generates heat

In addition, excessive sugar intake

It can also easily cause some body inflammation

So after relying too much on ice cream and cold drinks to "survive"

Instead, it may feel like

Dry mouth and tongue, discomfort

ask

So, what is a high-quality heat relief product?

In fact

Based on the principle of human body heat dissipation

The most effective way is to physically cool down

Blowing air conditioning, blowing fans, taking warm baths, etc

It's all a good way to cool down

in addition

When the brain detects an increase in temperature inside the human body

It secretes sweat by stimulating sweat glands throughout the body

And as the sweat on the body surface evaporates

The skin will cool down

Reduce the internal temperature of the human body through the flow of blood

So compared to cold drinks

Hot drinks can help the body transmit heat signals to the nervous system

After hot water enters the human body

Dilate blood vessels, promote pore opening

Promote the secretion of sweat glands

Thereby increasing the body's sweating rate

Bringing out heat from the body, causing a decrease in body temperature

In order to achieve a better cooling effect

Didn't expect it

Drinking hot drinks is a simple and thirst quenching method

If you sweat too much, you can also drink light salt water

in addition

It's also a good choice for relieving heat and cooling down

However, in the scorching summer

Facing the temptation of ice cream or cold drinks

It's hard to say no to the editor anyway!

Although it cannot truly relieve the heat

But ice cream, it

Really, good! Eat! Ah!
