Is Bluetooth earphones a radiation hazard?
As is well known, any electrical equipment has a magnetic field, and with a magnetic field, there is radiation. Experiments have shown that electromagnetic radiation beyond a certain range can cause harm to human health. So, will long-term wearing of Bluetooth earphones be harmful to health?
Firstly, everyone needs to know that whether the radiation from Bluetooth headphones affects health depends on the radiation intensity. The radiation generated by Bluetooth earphones belongs to non ionizing radiation, and the frequency of electromagnetic waves is relatively low, with relatively little impact on the human body. Usually, the higher the output power, the higher the intensity of the radiated electromagnetic field. Bluetooth earphones and electronic devices are generally only connected over short distances, with a transmission distance of only a few meters. As long as the power is very low, it can be achieved, and the radiation intensity is weak.
At present, the output power of Bluetooth earphones on the market is about 2-3 milliwatts, which is far less than the international regulations on radiation source safety. Therefore, it has little impact on human health and can be used with confidence.
What are the health hazards of Bluetooth earphones?
Although the use of Bluetooth headphones is safe, everyone should also be aware of potential health hazards in other areas.
The volume that a normal human ear can withstand is below 85 decibels. However, many children who use Bluetooth earphones do not pay attention to the volume of the earphones, which may expose their ears to high decibels. Over time, this may cause significant damage to hearing, especially some inferior earphones that may cause greater damage to the ears.
At the same time, earphones are also a "disaster zone" where there are many dead skin cells and bacteria that can attach to earplugs. If left uncleaned for a long time, it is likely to cause ear inflammation.
