Electromagnetic waves from smartphones and microwaves are safe!

[Cutting through with science] Are you lowering your QOL by worrying about electromagnetic waves from smartphones and microwaves? The truth about the "electromagnetic wave harm theory"

"Electromagnetic waves from microwaves are bad for your health"
"5G radio waves from smartphones cause health damage..."

Have you heard such rumors and tried to refrain from using microwaves or keep your distance from your smartphone?
It is wonderful to be health-conscious, but please wait a moment.

Is that "electromagnetic wave countermeasure" actually lowering your QOL (quality of life) instead?

In this day and age, 5G radio waves are already passing through our bodies everywhere in Japan.
If you go out to eat, there are powerful commercial microwaves in the kitchen, and Wi-Fi is flying around the city.
Imagine a life where you "avoid all of these." Don't you feel tremendous stress from all the restrictions?

It is counterproductive if actions taken for health end up having a negative mental impact and damaging your body due to stress. In this article, based on the latest scientific evidence, we will clearly resolve the "electromagnetic wave problem" of smartphones and microwaves.

Let's start with the conclusion.
"There is no problem with electromagnetic waves from microwaves and smartphones!"

1. The lie of the "microwave danger theory" whispered on the street

People often tell a plausible story that "microwaves were banned in Russia (the former Soviet Union) because they cause nearsightedness and cancer." However, that is nothing more than an old rumor from about 50 years ago. Currently, microwaves are widely used in daily life all over the world, and people in Russia also eat warm meals using microwaves as a matter of course.

And above all, there is no statistical data anywhere in the world that "households that use microwaves have a higher number of diseases" or "are more prone to cancer."

The conclusions of many public institutions and research reviews are always consistent. "No association is recognized."

2. The "true nature of electromagnetic waves" proven by science

Why can we say for sure that you won't get cancer from microwaves or smartphones? That is because the "type" of electromagnetic wave is completely different.

Let's organize the classification of electromagnetic waves by energy in an easy-to-understand way.

💥 Danger exists: [Ionizing radiation]

• Types: X-rays, gamma rays, ultraviolet rays (some), etc.

• Characteristics: The energy is extremely high, and it has the power to directly destroy cellular DNA. Because there is a risk of carcinogenicity, protection is necessary in places like hospitals.

🟢 No DNA destruction: [Non-ionizing radiation]

• Types: Visible light, infrared rays (kotatsu), microwaves (microwaves, smartphones, Wi-Fi, 5G), radio waves

• Characteristics: The energy is low, and it physically does not have the power to destroy DNA. It can only "warm up" objects (thermal effect).

The microwaves emitted by microwave ovens and smartphones are the latter, "non-ionizing radiation." Even in epidemiological studies (follow-up surveys of large human populations), no difference in cancer incidence has been confirmed between microwave users and non-users. The American Cancer Society, a trusted U.S. organization, also clearly declares that "there is no evidence that properly used microwave ovens pose a health risk."

3. Why does the "danger theory" continue to spread?

Given that safety has been proven so scientifically, why are there still so many people who say "microwave ovens are dangerous"? The reasons mainly lie in the following three "misunderstandings and confusions."

• ① The term "radiation" taking on a life of its own This is a case where people misunderstand it as "= dangerous, just like nuclear power plants or X-rays" simply because of the sound of the word "radiation" included in the term "non-ionizing radiation." They are afraid based solely on the image of the word.

• ② Confusion with occupational exposure to "military radar" Some old studies that claim "electromagnetic waves are bad for the body" targeted people who were exposed to powerful microwave equipment for long periods at close range such as military radar technicians. However, this is a story about "occupational exposure" where one is bathed in thousands to millions of times the energy of a home microwave oven. It is a completely different story from heating up a lunch box at home.

• ③ Confusing the issue of "containers" with the issue of "electromagnetic waves" Actually, what can be a problem in microwave cooking is not the electromagnetic waves themselves. It is the issue of chemical substances leaching out when heating "inferior plastic containers not suitable for microwave use," or the risk of burns due to overheating. These have been swapped, leading to the misunderstanding that "microwave ovens are bad."

4. Microwave ovens are actually "excellent cooking appliances"

Far from being dangerous, microwave ovens are, depending on how you use them, excellent cooking tools that retain the most nutrients.

• Cooking time is overwhelmingly short

• Does not use large amounts of water like when boiling

Many studies have shown that this prevents vitamin C and water-soluble nutrients from flowing out into the water, resulting in a higher nutrient retention rate. More nutrients remain when you heat vegetables in the microwave than when you boil them.

5. "Three realistic rules" you should really be careful about

There is no need to be afraid of non-existent electromagnetic wave risks, but for physical safety, please follow these "realistic rules."

1. Do not use plastic containers that are not microwave-safe (To prevent chemical substances from leaching out. Always check for the "microwave-safe" mark)

2. Do not use broken microwave ovens or machines where the door does not close tightly (To prevent microwaves from leaking out and causing direct heat damage such as burns)

3. Be careful of "bumping" in liquids (If you heat coffee or similar liquids too much, there is a danger that they will suddenly boil and splatter due to impact)

As long as you follow these, the microwave oven is the best partner to enrich your life.

6. Summary: Let's make science our ally and achieve the best QOL

Our surroundings are filled with all kinds of electromagnetic waves, such as 5G, Wi-Fi, and Bluetooth. Living in fear, convinced that these are 'poison,' drains your mind and body more than you can imagine.

There is currently no evidence in the scientific community that 'electromagnetic waves from microwave ovens cause cancer.' More importantly, the 'joy of eating warm food you want to eat' and the 'relaxation time created by saving time on housework' have an overwhelmingly positive effect on your health and mental well-being.

Let go of baseless anxiety and make smart use of convenient technology. Achieve the best quality of life that is stress-free, unrestricted, and uniquely yours!
