Is it true that a magnet or magnet is placed at the head of the bed has a hypnotic and sleep aiding

In the long run, it is harmful to the human body, and it should be kept away, especially not at the head of the bed, and the impact on the mobile phone signal also depends on the magnetic force of the two magnets.

The harm of mobile phone radiation to the human body is a misunderstanding. Radiation is a way of transmitting energy, including light, heat, etc. The radiation of mobile phones and computers is mostly waves of different frequencies, which you can understand as basking in the sun. As for whether you think sun exposure is harmful or harmless, it's up to you what you think.

High-frequency electromagnetic waves are the most harmful part of electromagnetic radiation to the human body. But the radiation we are exposed to on a daily basis (such as computers, mobile phones, etc.) is far from the level that can damage DNA (yes, they are not high enough frequency). The closest high-frequency electromagnetic waves to us are X-rays during subway security checks and chest X-rays during physical examinations.

However, the X-ray equipment during the security check will not leak out of the equipment, and as long as you do not put your hand into the security machine every day, there will be no safety problems. As long as the X-ray radiation during the physical examination is not taken every month, the damage to the human body can be ignored.
