5 Bad Impact of Noise Pollution on Health
Windowofworld.com – Noise pollution has become a part of daily life, especially for residents who live in urban areas. Unwittingly, sound pollution can actually have a negative impact on health, ranging from hearing problems, sleep disorders, to an increased risk of heart problems.
You who live in urban areas must be familiar with the noise from vehicle engines, construction projects, industrial activities, or loud noises from neighboring homes. Not only that, the noise you might often hear when using a headset.
Although some people may already be accustomed and do not consider this noise pollution as dangerous, but various health studies show that continued exposure to noise pollution can lead to health problems.
Adverse Effects of Sound Pollution
There are many adverse effects of noise pollution for human health, including:
1. Hearing Loss
People who are frequently exposed to high-risk noise pollution experience hearing loss, especially if the intensity of the sound they often hear exceeds 75-85 decibels (dB) and lasts for a long time.
As an illustration, a soft whisper is equal to 30 dB, the sound of busy road traffic or the sound of a vacuum cleaner with a intensity of 80 dB, while the sound intensity on a chainsaw can reach 110 dB.
Sounds above normal intensity can weaken the ability of hearing cells in the ear. If you are too often exposed to noise, your ears can buzz (tinnitus). This tinnitus can be temporary, but can also be permanent if loud voice exposure occurs in the long term.
Hearing loss due to noise pollution can interfere with the ability to understand speech, difficulty concentrating, to interfere with daily productivity.
2. Sleep Disorders
Quality sleep with sufficient duration (about 7-9 hours for adults) is very important for physical and mental health. A person’s sleep quality can be reduced if there is noise around him during sleep.
Sounds above 33 dB at night can trigger the body’s natural reactions which can disrupt sleep quality. Sleep that does not sleep will affect mood, resulting in fatigue, to reduce memory and concentration.
Sleep disturbance due to exposure to noise pollution that is too often this can cause stress and reduce quality of life.
3. Cognitive disorders
Prolonged noise can affect cognitive abilities (learning and thinking), both in adults and children. People who often hear noise at work are more at risk of having difficulty remembering, concentrating, to regulating emotions.
A health research also explained that exposure to noise pollution that is too often in children can affect the ability to learn, concentrate, and remember. In infants and toddlers, this can cause delays in talking.
4. Cardiovascular disease
Cardiovascular disease is a disease related to the heart and blood vessels. Cardiovascular disorders arising from noise pollution are actually associated with sleep disorders.
Sleep is a very important activity because at this time the body is resting and repairing damaged tissue, as well as regaining its energy. If the quality of sleep is disturbed, then the organs of the body can experience decreased function, including the heart and blood vessels.
These effects will begin to appear if you are exposed to noise above 65 dB every day in the long run. Exposure to noise will activate the body’s stress response in the form of the production of the hormone cortisol (stress hormone) which results in increased blood pressure, blood viscosity, and heart rate.
5. Mental disorders
Noise pollution can increase a person’s risk for experiencing mental disorders, such as anxiety, stress, anxiety, unstable emotions, and even aggressive behavior due to stress or psychiatric problems that previously had.
Noise pollution also has a dangerous impact on pregnant women and newborns. Exposure to noise to the fetus in the womb and newborns can increase the risk of hearing loss.
If you live or have a lot of activities in an area close to the source of noise pollution and feel experiencing some of the health problems mentioned above, immediately check your ear health to the ENT doctor.
To protect yourself from noise pollution and prevent health problems caused by noise pollution, wear ear protectors, such as earmuffs or earplugs, when on the move.
