What are the adverse effects on the body of people living in a noisy environment for a long time?

Hearing loss and deterioration, unresponsiveness.

1. Interfere with life and workSleep is an important condition for people to eliminate fatigue, restore physical strength and maintain health. However, noise can affect the quality and quantity of sleep, and the elderly and sick are more sensitive to noise disturbances.

When sleep is disturbed and you can't fall asleep, you will experience frequent breathing, increased pulse beating, nervous excitement and other phenomena, and the next day you will feel tired and tired, which will affect work efficiency. Over time, it can cause insomnia, tinnitus and dreams, fatigue and weakness, and memory loss, which is medically known as neurasthenic syndrome. In a high-noise environment, the incidence of this disease can reach 50 60 .

2. Hearing impairment:The most direct harm of noise to the human body is hearing damage. When people enter a noisy environment and are exposed to it for a period of time, they will feel uncomfortable in both ears and even have headaches.

Leave the noisy environment and rest in a quiet place for a while, and your hearing will gradually return to normal. This phenomenon is called temporary hearing threshold shift, also known as auditory fatigue. However, if people work in a loud noise environment for a long time, auditory fatigue cannot be recovered in time, and organic lesions will occur in the inner ear organs, that is, permanent hearing threshold shift, also known as noise deafness.

3. Induce a variety of diseases:Because noise acts on the central nervous system of the brain through the hearing organs, thus affecting all organs of the body, noise not only causes damage to people's hearing, but also brings harm to other systems of the human body. As a result of noise, neurasthenia such as headaches, brain swelling, tinnitus, insomnia, general fatigue and weakness and memory loss can occur.

People who work in high-noise environments for a long time have 2 to 3 times higher incidence of hypertension, arteriosclerosis and coronary heart disease than those who work in low-noise environments. Visible noise can cause diseases of the cardiovascular system.

Long-term noise generally has the following effects on people. First of all, it may lead to noise-induced deafness, which is mainly manifested by hearing loss and tinnitus. In severe cases, complete hearing loss may occur.

Secondly, it may cause mental anxiety. If you live in noise for a long time, it is easy to cause anxiety, which can be manifested as irritability, restlessness. In severe cases, somatization symptoms such as palpitation, chest tightness, and memory loss may occur.

In addition, it may lead to autonomic and endocrine dysfunction.

Long-term noise can interfere with life and work, damage hearing, and induce a variety of diseases.

40 dB is normal ambient sound and is generally considered the hygienic standard for noise. Above this is harmful noise, which is quite harmful to people. Noise of about 50 decibels will affect rest and sleep, which in turn will affect the normal physiological functions of the human body.

Noise above 70 decibels can make people upset and unfocused, which not only reduces work efficiency, but also may cause accidents. If you live in a noisy environment above 90 decibels for a long time, you will have hearing damage, headaches, nausea, increased heart rate, and unstable blood pressure. The hazards of noise can be summarized as follows:

1. Interfere with life and work.

2. Hearing impairment.

3. Induce a variety of diseases.

Noise is a type of sound that causes irritability or is too loud and harmful to human health. Noise can be physically and psychologically harmful: if people work in a loud noise environment for a long time, it will damage the hearing tissue of the inner ear, and in severe cases, it will cause deafness.

Noise acts on the central nervous system of the person, which can lead to abnormal conditioned reflexes for too long, and symptoms such as headaches, tinnitus, dreams, and insomnia will occur.

The harm of long-term noise environment can mainly lead to deafness, tinnitus and other auditory nervous system lesions. Prolonged exposure to noise is actually a chronic acoustic damage that can cause irreversible damage to the sensorineural system of the inner ear. And it is positively correlated with the degree of noise and the time of contact.

Living in a noisy environment for a long time has a great impact on people, if you don't get quiet for a long time, then his heart will become more and more impetuous, and in serious cases, he will get anxiety.

Living in a noisy environment for a long time may have a very bad effect on your ears or brain, and over time, your ears will not be able to hear clearly.

It will have a great impact on physical and mental health, and the serious impact is on the hearing system, and people are easily irritable in a noisy environment.

Living in a noisy environment for a long time has a serious impact on people's hearing.

I think if you live in such an environment for a long time, you will definitely be very anxious at first.

It will cause a burden on the eardrum, and long-term exposure to noise may cause hearing disability.

It will have a certain impact on the ears, so be careful or you will regret it too late if there are serious consequences.

It will be anxious, nervous sensitive, and will have a nervous breakdown in the long run.

It has an impact on people's health.

In my opinion, irritability.

1. Reduce work efficiency. A recent study published in The New Yorker magazine found that ambient noise in open-plan offices can lead to reduced employee productivity. Noises of all kinds can lead to a decrease in employees' ability to remember and recall, as well as a decrease in basic skills such as simple calculations.

Distraction is a big factor, but more importantly, the noise of a large, open-plan office can lead to increased stress among employees, according to the researchers.

2. Environmental noise increases the risk of fatal heart disease. In 2011, a study completed by the Joint Research Centre of the World Health Organization and the European Executive Committee found that long-term exposure to noisy traffic such as airplanes and trains led to an increased risk of high blood pressure and fatal heart disease.

3. Noise especially disturbs people who complete multiple tasks at the same time. Dr. Anthony Wegener, an expert in cognitive neuroscience at Stanford University in the United States, said that noise disturbances make it harder for people to stop distractions, and it is harder to concentrate, so it is more difficult to complete multiple tasks at the same time. When the work at hand is interrupted by noise, it is often more difficult to continue to return to the work that was just done.

Healthy and light: Living in a noisy environment for a long time will not only affect hearing, but also lead to the occurrence of other diseases.
