Is Bluetooth headset harmful, please everyone, thank you

I think what you want to know is whether Bluetooth is harmful to the human body, right? Bluetooth radiates only a few tenths of the radiation of a mobile phone. It is almost negligible, and it can be used with confidence.

Even so, the damage to the eardrum and hearing from the earphones is considerable. Especially in-ear! It is not recommended to wear headphones for long periods of time.

Bluetooth headsets are wirelessly connected through electromagnetic waves, and there is a certain amount of electromagnetic wave radiation, and ordinary wired headphones themselves have no radiation.

1.The study found.

According to studies, wearing Bluetooth headphones for a long time can cause hearing damage to people. This is because when using Bluetooth headphones, Bluetooth signals need to be transmitted to the headphones, and this transmission process produces radiation similar to radio waves, which is absorbed by the body and has health effects.

2.Extent of injury.

The extent to which Bluetooth headphones can damage your ears depends on how long you use them, how loud they are, and how well your ears tolerate them. Generally speaking, if you use high-volume Bluetooth headphones for a long time, the eardrum and auditory nerve will be damaged, which will cause symptoms such as hearing loss, tinnitus and headaches.

3.How to reduce the damage.

In order to reduce the damage caused by Bluetooth headsets to the ear, the following measures can be taken: First, choose the appropriate size earbuds so that they can fit snugly in the ear, and avoid excessive expansion of the eardrum and reduce the risk of hearing loss while effectively anti-interference and noise reduction. Secondly, it is best not to turn up the volume too much when using Bluetooth headsets, and you should learn to be patient and gradually adapt to the surrounding sounds.

In addition, it is generally believed that it is safer to listen to the volume slowly.

4.Precautions.

When using Bluetooth headsets, you also need to pay attention to the following: first, do not wash and wipe frequently, so as not to cause damage and pollution; The second is to try to avoid wearing it for too long, relax the ear muscles moderately, and give the eardrum and auditory nerve sufficient rest time; Finally, it is necessary to avoid sharp changes in pitch, as this change can excite the auditory nerves violently, which can easily lead to ear damage.

5.Alternatives.

If you're concerned about damage to your ears from Bluetooth headphones, you can choose other alternatives to protect your ears. For example, use wired headphones, stereos, and other equipment, and maintain proper physical activity and a good diet. In addition, children or the elderly should try to avoid using high-tech devices such as Bluetooth headphones to protect their fragile hearing system.

6.Develop healthy listening habits.

Finally, in order to reduce the damage of Bluetooth headphones to the ears, it is necessary to develop healthy listening habits. For example, avoid factors such as random listening** and excessive chatting, avoid listening to high-frequency, high-decibel noise for a long time and other factors that interfere with our health, and pay attention to environmental protection and healthy diet in life, which can effectively protect and delay the aging of the ears.

Therefore, although Bluetooth headsets have certain damage to the ears, as long as you pay attention to the use and develop healthy listening habits, you can effectively prevent and reduce the damage and make your hearing continue to be healthy.

Bluetooth headset is another great invention of human beings, more convenient than wired headphones, can bring a lot of convenience to life, but due to the influence of wireless electromagnetic waves, does Bluetooth headset bring greater harm to the human body? What are the dangers of Bluetooth headsets to the human body? As long as the Bluetooth headset is used properly, it is still very convenient next to the branch, so let's learn more about the Bluetooth headset.

1. Are Bluetooth headsets harmful to the body?

Bluetooth headsets have no obvious harm to the body. The radiation value of Bluetooth headset is about 1MW kg, which is far lower than the requirements of international radiation standards. China stipulates that the radiation value of Bluetooth headsets shall not exceed 1w kg, which is low to this standard, and radiation will not cause harm to the human body.

2. Bluetooth headset radiation is harmful

At present, the industry believes that when the radiation is less than 2w kg, the impact on human health is very small, and when it is less than 1w kg, it will not cause harm to the human body. There are two international standards for radiation, the European standard is 2W kg, and the American standard is, that is, the average time is 6 minutes, and the electromagnetic radiation energy absorbed by each kilogram of human tissue shall not exceed 2W or.

3. What are the dangers of Bluetooth headset radiation to the human body?

The headphones are powered by Bluetooth technology, which sends low-intensity radio waves to the ears. Studies have shown that sending radio waves into the ear for too long can weaken the brain's vascular barrier, which is an important organ that prevents chemical toxins from entering the body. Therefore, the use of Bluetooth headsets that exceed the radiation value may increase the risk of disease in people.

4. Avoid Bluetooth headsets from harming your body

When using mobile phones, you should try to use Bluetooth headsets as little as possible, and do not use Bluetooth headsets for a long time to listen to songs, play **, etc., so as to reduce the body's absorption of radio waves and reduce the damage of wireless radiation to the body.

5. Ways to avoid hearing damage

1.Wear headphones to master the "60 principle": people who often wear headphones, especially built-in headphones, should master the 60-60-60 principle, which is also an internationally recognized method of hearing protection, that is, when listening, 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 a headset: Headphones are usually divided into three types: headphones, over-ear and in-ear, with the one that causes the least damage to the ear being the headset. Comparatively, long-term use of in-ear headphones in noisy environments may cause hearing damage.

3.Try not to listen with headphones in a noisy environment**, in the subway, bus, in order to hear the content clearly, you will involuntarily turn up the volume. Especially in the subway, it is a relatively closed environment, and if you put on headphones and press them tightly on your ears, you can imagine the damage to the auditory hair cells.

When listening, don't pursue the sound quality effect too much, and put the low-frequency sound very large; Wear less headphones when listening indoors**.

4.People who often listen to ** should pay attention to their hearing, and when there are tinnitus, ear stuffiness, dizziness, lack of concentration and other phenomena, we should be vigilant. Hearing loss should be seen as soon as it is noticed.
