1. Is Bluetooth headset harmful to health?
Bluetooth headset has no obvious harm to the body. The radiation value of Bluetooth headset is about 1mW/Kg, which is far below the international requirements for radiation standards. However, China stipulates that the radiation value of Bluetooth headset shall not exceed 1W/Kg. Below this standard, radiation will not cause harm to human body.
2, Bluetooth headset radiation is harmful
At present, it is considered in the industry that radiation has little impact on human health when it is below 2W/Kg, but it will not do harm to human health when it is below 1W/Kg. There are two international standards for radiation, the European standard is 2W/ kg, and the American standard is 1.6W/ kg, that is, the electromagnetic radiation energy absorbed by human tissues per kg in an average time of 6 minutes should not exceed 2W or1.62w. ..
3. What harm does Bluetooth headset radiation do to human body?
Headphones are driven by Bluetooth technology and send low-intensity radio waves to ears. Studies have shown that if radio waves reach the ears over time, the vascular barrier of the brain will be weakened, and the cerebrovascular barrier is an important organ to prevent chemical toxins from entering the body. Therefore, the use of Bluetooth headsets exceeding the radiation value may increase the risk of human illness.
4. Avoid the harm of Bluetooth headset to the body.
When using a mobile phone at ordinary times, use Bluetooth headset as little as possible, and don't use Bluetooth headset to listen to songs and make phone calls for a long time, so as to reduce the body's absorption of radio waves and reduce the harm of wireless radiation to the body.
5. Ways to avoid hearing loss
1. Wearing headphones should master the "60 principle": People who wear headphones frequently, especially those with built-in headphones, should master the 60-60-60 principle, which is also an internationally recognized method to protect their hearing, that is, when listening to music, the volume should not exceed 60% of the maximum volume, the continuous listening time should not exceed 60 minutes, and the external sound should not exceed 60 decibels.
2. Choose headphones: headphones are usually divided into three types: headphones, ear-hanging headphones and in-ear headphones, of which headphones have the least damage to the ears. Relatively speaking, long-term use of in-ear headphones in noisy environment may cause hearing damage.
Try not to listen to music with headphones in noisy environment. On subways and buses, in order to hear clearly, you can't help raising the volume. Especially in the subway, it is a relatively closed environment. If you put on headphones and press them tightly on your ears, the damage to auditory hair cells can be imagined. When listening to music, don't pursue the sound quality excessively, and put the low-frequency sound very loud; Wear less headphones when listening to music indoors.
People who often listen to music should pay attention to their hearing, and when tinnitus, stuffy ears, dizziness, inattention and other phenomena appear, we should be alert. Once hearing loss is found, you should seek medical attention immediately.
