γ (gamma) rays are a type of radiation.

We live in constant exposure to natural radiation.

It constantly rains down on us from space, and we also receive it from the earth, air, and food.

The human body, which has lived for generations while being exposed to radiation since ancient times, is equipped with functions to cope with radiation.

A good example is ultraviolet light.
While continued exposure to strong ultraviolet rays can cause age spots and aging, moderate exposure to ultraviolet rays (sunlight) has beneficial effects, and humans cannot live without sunlight.

Similarly, modern people living in cities where asphalt and concrete have blocked natural radiation from the earth and atmosphere may not have enough natural radiation.


Through this bedding, people are able to regain their original performance by compensating for the lack of radiation.

I hope you understand this.
