The Effect of Microwave on Human Body

The Effect of Microwave on Human Body

1. The Effect of Microwave on Human Body

My mom told me not to look at the microwave when I was young.
The electromagnetic waves from the microwave oven are not good for your health, so you should not go near them.
I remember putting gold stickers on the microwave to block electromagnetic waves. I’ve been living believing that word.

But at some point, I got these questions.
“Is microwave ovens really bad for you? Then why do we cook a lot of food in the microwave?’
As a result, he began to study microwave in earnest.

The finding was that “the microwave oven is more harmless to the human body than you think.”

– Summary: Let’s see if the microwave is really harmful to the human body.

2. How does the microwave work?

A microwave is a machine that heats objects using microwave, an area of electromagnetic waves.
Microwave is an electromagnetic wave that has more energy than radio waves and less energy than infrared waves.
It is also used for electromagnetic artillery, laser, navigation, and communication, and is inexpensive and harmless to the human body.

Microwaves from microwave ovens heat objects.

Microwave came into the world in 1940 with an invention called “Magnetron” developed by Harry Boot and John Randall, scientists at the University of Birmingham in the United Kingdom.

Magnetron is a mechanical device that allows humans to create arbitrary microwaves.

Originally, microwave was mainly used as a radar for the military industry.
Meanwhile, the microwave was invented by Percy Spencer, who worked for the U.S. defense industry “Lacion.”

He discovered that microwave generated by magnetron increases the temperature of moisture.
The invention created using the idea is a microwave oven.

Microwaves vibrate moisture at high speeds. Thus, during the vibration process, the object heats up due to heat generation.

In other words, microwave does not generate or transmit heat in itself.
It simply vibrates the water molecules in the food quickly, generating heat.

– Summary: Microwave from microwave oven vibrates moisture and makes food hot.

3. Is microwave ovens harmful to the human body?

You’ve probably heard a lot that electromagnetic waves from microwave ovens are harmful to our bodies.
Then why did this story come out? As previously explained, microwave makes water hot by vibrating it.

This is where a ghost story is born. Our body consists of numerous water molecules such as cerebrospinal fluid and blood.
In other words, the word came from the idea that microwaves from microwave ovens can also affect the moisture of our bodies.

The idea that moisture in our bodies can also be influenced by microwaves gave birth to a ghost story.

But to begin with, microwaves from microwave ovens are not very harmful to our bodies.
This is because only a very small amount of electromagnetic waves occur for the corresponding electromagnetic waves to have a harmful effect on our bodies.

Microwave radio energy is usually trapped in the microwave.
Some leaked electromagnetic waves fall far short of safety regulations.

– Summary: Microwave strength from microwave ovens is harmless to the human body.

4. Numerous questions surrounding the microwave

(1) Microwave cooking food is not good for your health?

It’s not true. Microwave cooking does not destroy nutrients.
Nutrient destruction occurs only when the temperature of the food rises too much or when it receives waves such as ultraviolet rays.

The frequency of microwave, an electromagnetic wave from microwave ovens, does not cause nutrient destruction.
Therefore, cooking food in microwave does not have harmful effects.

(2) Is it harmful to be near the microwave?

This is also not true. As mentioned earlier, the microwave’s radio energy is mainly trapped in it.
Some leaked electromagnetic waves are below safety regulations.

However, it can be harmful if the microwave is turned without anything inside, or if it contains only a small amount of food.
This is because without moisture, radio waves cannot be absorbed, so the power of leakage can be higher than the standard.

It is also likely to be harmful even if the microwave is old and broken. Especially if you look at the microwave turning very close, it can have a fatal effect on your eyes.
This is because microwave can affect the moisture in the eyes.

Therefore, when the microwave is running, it is recommended to look at at least 30cm apart.

(3) Electromagnetic waves are harmless to the human body?

Strong electromagnetic waves are dangerous, but weak electromagnetic waves from home appliances are not dangerous.
Until now, electromagnetic waves that occur in everyday life are very weak. This does not affect the human body.

However, it has yet to be revealed that there has been constant exposure to weak electromagnetic waves for a long time.
In other words, even weak electromagnetic waves can be harmful to the human body if exposed for a long time.

(4) Are charcoal, cactus, and electromagnetic blocking stickers effective?

To begin with, it doesn’t work.
According to a study conducted by the National Radio Research Institute, charcoal, cactus, and electromagnetic blocking stickers were found to be ineffective.

Cactus is mostly made of moisture, so it can partially absorb microwaves emitted by microwave ovens.
However, this effect requires the entire microwave oven to be blocked with cactus.

Electromagnetic waves decrease rapidly depending on the distance, so it is most important to stay away.

– Summary: Electromagnetic waves from microwave ovens are not very harmful to the human body.
