In our daily life, we often see many teenagers listening to MP3 with headphones, which seems to be very enjoyable. But in the doctor's opinion, it is easy for teenagers to use MP3 carelessly, which will damage their hearing, affect their brains, nerves and blood pressure, and lead to some diseases.
MP3 impairs hearing. In order to be portable, most modern MP3 players listen with headphones. After the earphone is inserted into the ear hole, the sound emitted is relatively concentrated, which stimulates the ear far more than the usual external sound. Listening to MP3 for too long or loud will have a bad effect on auditory nerve.
Teenagers' listening is in a period of perfection. If the auditory nerve is strongly affected for a long time, nerve cells will be damaged and die or shrink, leading to progressive hearing loss, which will seriously lead to hearing loss.
Modern medical research shows that sound is also a kind of energy. When the human body is stimulated by sound, the brain will be excited and the nervous system will fluctuate. Teenagers don't know how to listen to MP3 properly, and often listen for hours with headphones on. When the brain is stimulated by sound for a long time, it will be overexcited, but it will inhibit the activity of cells, cause slow response and even reduce the level of intelligence.
Parasympathetic nerves are prone to disorder under the continuous strong sound stimulation of the nervous system, causing endocrine abnormalities, blood pressure fluctuations and other problems, which are easy to cause headaches, insomnia, nausea, fatigue, arrhythmia, hypertension and other symptoms for teenagers, seriously affecting their health.
MP3, as a product of modern science and technology, is helpful to the study and life of teenagers, but for the sake of health, teenagers should pay attention to scientific use. When listening to MP3, take a rest every 1 hour 10 minute, try to avoid irritating ears for a long time, and adjust the MP3 volume to avoid hearing damage. After listening to MP3, you can massage your ears and head properly to promote blood circulation and ear health.
