Important! The natural noise background is about 20-30 dB. This level is safe for our nervous system and hearing organs. Loud sounds up to 80 dB of time-dosed exposure are not dangerous, but such a background for a megacity is a rarity. The average noise level in the busy streets of Moscow and other major cities of Russia is at least 90 dB, which is higher than the permissible rate.
Noise and body
For a long time, the effect of noise on the human body has not been specifically studied. Thanks to many studies it turned out that it has a slow, but extremely destructive effect. In addition to the fact that increased noise levels are the cause of hearing loss, worsening of labor productivity, violation of concentration, increase in blood pressure, it also affects our attitude towards each other. Under the influence of loud noises people behave more aggressively: 70% of neuroses arise precisely because of noise. The person is emotionally exhausted. Not knowing how to fill up his resources, he again saturates himself with an imaginary rest (radio, television, computer). As a result, there is a mental imbalance, aggression accumulates and a person breaks down on the close, subordinate, surrounding people.
Electric discharge
Today it's hard to imagine life without electrical appliances and public transport. They are the source of constant noise in our homes, at work and on the way to it.
A mobile phone is the most common "pest" for our body. On average, a person talks by mobile phone for about 100 minutes per month. This is quite enough to harm the psyche and the body as a whole. Protection: the volume of the headset of mobile phones should not exceed 10 dB (that is, the volume of the ring and the conversation with the subscriber should not exceed the average). Otherwise, with frequent calls and conversations, nervous disorders can begin.
Important!
According to the World Health Organization, listening to loud music through headphones regularly for 1-2 years can reduce the threshold of audibility by 20-30%, and it will be difficult to restore hearing.
Office equipment. Office workers are affected by noise background in 50-70 dB - like these figures are less than the acceptable limit, but the sound is constant. The monotonous buzz of office equipment has a strong strain on our nervous system. As a result - fatigue, nervous breakdowns at the end of the working day. Defense: Arrange yourself a 15-minute rest every two hours. At this moment, leave the room in a quiet place, close your eyes and breathe quietly. This will reduce the level of stress and will give strength to continue work.
Metro is a constant stress for the body. In Moscow, the noise at some stations exceeds the permissible standards, amounting to 99 dB and even 104 dB. That's why many experience stress and nervous tension in the "subway". Protection: "Leaving the metro, walk 10 minutes along the street, inhale deeply and exhale slowly. So you quickly remove the body from a stressful state.
By the way! Many great composers specially composed medical music. For example, Bach's "Geldberg Variations" were written as a remedy for insomnia.
MP3 player, as well as a phone, is vital for many people. But listening to music through headphones is not so harmless. On average, the owner of mp3 player includes music at a level above 80 dB. Headphones increase the volume by another 7-9 dB. This means that the probability of getting deafness increases several times. Protection: "Limit listening to music for up to half an hour a day and no more. The volume should not exceed 8o dB. This sound background will not have a negative impact of noise and vibration on the human body and on the hearing aid and the nervous system.
By the way! How powerful a destructive effect is the noise, you can check on our smaller brothers. For example, the sound from a flying jet plane depressingly affects the bee, it loses the ability to navigate. The same noise kills the larvae of bees.
To listen to silence
To reduce the negative impact of city noise, it is necessary to conduct "preventive sessions of silence" and relaxation days. Restoring the body and replenish the vital forces will help our advice.
Wellness silence
Perhaps, one of the most interesting prophylaxis. 10 minutes a day "contemplation" of silence will help you get rid of noise overloads. How it works: Disconnected phones, TVs, radios, computers. A few minutes you are not for anyone. There is only silence and you. Being, for a time in complete peace and relaxed pose, your body begins to recover quickly. Calm cells of the brain are calming, heartbeat is normalized, the psyche is in balance. Important: Try to find time for this training. It should become one of the useful habits.
Ignore TV
Most of us are used to the fact that the TV is a kind of background for other activities. A similar error can become fatal. The noise from the TV distracts us from talking, doing housework and even eating. How it works: Turn off the TV for the whole day and turn it on only when there is a really important transmission or an interesting film. The rest of the time the TV should "decorate" the room in an idle state. When the unnecessary noise is over, it becomes possible to do really important things. Important: Arrange family views, which do not exceed two hours. Then it is desirable to sit in silence or just talk about something over a cup of tea.
Natural gifts
They are an excellent anti-stress drug. And they help to relax completely. How it works: In nature, your nervous system can recover well. Scientists from the Australian Psychological University found that each phenomenon of nature has its own characteristics. For example, rain soothes, the waterfall lifts the mood, and singing birds brings a sense of happiness. Important: Being in nature, learn to enjoy what it gives you. In particular, silence, tranquility, pacification. After all, in a big city is a rarity.
Selection of compositions
This is an important aspect of noise control. Choosing music, you need to think not only about your preferences, but also about how they affect our body. Classical music is best for relaxation. How it works: The latest research, one of the leading educators in the field of music and healing in the world, has shown that under the influence of classical music stress is removed and the body replenishes its strength. Important: Do not exceed the volume! Even the most pleasant and calm melody at a loudness of 10% can lead to deafness.
