You can get dangerous bacteria when singing karaoke.

After a full meal, the stomach volume increases, the stomach wall thins, and blood flow increases. At this time, the act of singing karaoke will increase stomach pressure, leading to poor digestion, and more seriously, intestinal and stomach diseases.

Furthermore, many people like to scream loudly when singing. If they have drunk alcohol beforehand and their throats are irritated, showing off their voices will cause blood to rush to the larynx and throat, causing congestion or chronic pharyngitis.

According to Master Luu Lien Huong, the microphone is considered an indispensable device in karaoke rooms but is often forgotten by service staff when cleaning.

When the microphone user makes a sound, saliva will stick to the microphone mesh and foam. If not cleaned regularly, the foam and metal mesh will accidentally become a breeding ground for disease-causing bacteria.

“Previously, the Pasteur Institute of Ho Chi Minh City analyzed 3 microphone samples from 2 family karaoke entertainment establishments and found that one microphone sample was infected with up to 41,000 yeast cells, and the other two samples contained Staphylococcus aureus - a toxic strain of bacteria. Staphylococcus aureus is a dangerous opportunistic infection that is easily spread when the body's resistance is weak. When exposed to scratched skin, this bacteria produces pus, causing skin infections, and through the mouth, causing mouth ulcers and throat ulcers,” said Master Luu Lien Huong.

In addition, the current structure of karaoke service rooms causes a lot of mold bacteria to be present in the air. Therefore, the possibility of causing respiratory diseases is inevitable for people with weak resistance.

To avoid the risk of illness when going to karaoke, Master Luu Lien Huong recommends not using alcohol or stimulants when going to karaoke, choosing reputable karaoke establishments, fully equipped with machinery, especially fire and explosion-proof equipment, preferably in airy, ventilated rooms, with exits, and clean hygiene.

According to this expert, karaoke is an activity that causes noise. Recent studies have concluded that you are at risk of hearing loss due to the noise in a closed karaoke room. The reason given is that singing through a microphone will be amplified above the background music, creating a noise level of up to 95dB. When you spend 2 hours in a karaoke room, your hearing will decrease by 8dB, directly affecting your ability to hear later.

In addition, when conducting tests in karaoke rooms, experts found that there are many aerobic bacteria and molds in the air such as Bacillus, Coccus, Sprillum... These bacteria, when entering the human body, will cause many dangerous diseases such as tetanus, typhoid fever, sepsis, allergies and respiratory infections.

When you sing karaoke, in addition to using your volume to express the songs, you also have to talk and cheer for others at a fairly loud volume. Not being able to control the volume will put your throat at risk of serious damage. The consequences can lead to torn vocal cords, coughing, and even loss of voice.
