What Are the Effects of Noise Pollution on Human Health?

effects of noise pollution on human health

When undesired noises infiltrate the environment, they cause noise pollution. Noise pollution may harm your health. Stress, improper sleep, or hearing impairment is among the common side effects of noise pollution on human health. Noise-Induced Hearing Loss (NIHL) is the most prevalent health condition caused by it.

Loud noise can induce high blood pressure, heart disease, and sleep difficulties. These health issues might have an impact on the health of the children as well.

Construction sites, vehicles, crowds, loud noises, metropolitan areas, and airplanes are all examples of noise pollution sources.

This article will discuss the effects of noise pollution on human health. We will also talk about how to prevent noise pollution and its side effects.

Overview of noise pollution

Noise pollution is the spread of undesired noises into the environment. The presence of noise is nearly always present around us.

This noise can be produced naturally or by human activities. Noise pollution may have an impact on both humans and animals.

Noise pollution is often overlooked as a health threat. According to a study, it is a factor that is underreported.

Because of increased human activity, many individuals are witnessing an increase in noise pollution. As a result, the effects of noise pollution on human health are increasing.

Effects of noise pollution on physical health

Physical health impacts of noise pollution might arise as a direct or indirect outcome of noise exposure.

Loud noises can directly cause hearing damage in extreme circumstances. NIHL can affect a person in a variety of ways, including:

  • Tinnitus – is characterized by a persistent high-pitched ringing in the ears.
  • Paracusis – distortion of hearing ability

Some studies also show that noise pollution may lead to other health problems in an indirect way.

There is evidence that short-term noise pollution exposure can elevate blood pressure. Long-term exposure to noise may increase the risk of cardiovascular disease.

According to the study, noise pollution may have an impact on stress hormones and the neurological system. This stress can lead to illness development.

A Canadian study discovered that pregnant women who were exposed to greater levels of noise pollution were more likely to develop preeclampsia – a condition that causes high BP.

Effects of noise pollution on mental health

Unwanted noises can have a variety of mental health consequences. Even when sleeping, the brain listens for indicators of danger.

Anxiety or stress can be intensified by loud noises. The longer a person is exposed to noise pollution, the more sensitive he or she becomes to stress.

People who live in areas prone to noise pollution may become infuriated. Noise has a greater influence on a person’s mental health when they believe they have no control over it.

Environmental noise is another prevalent source of sleep disruption. A person may suffer the following symptoms:

  • Difficulties falling asleep
  • Stress
  • Inability to keep asleep
  • Mood swings due to improper sleep
  • Waking up too early

Sounds can also affect sleep quality by influencing the quantity of rapid eye movement sleep. It can harm a person’s mood and ability to focus.

Effects of noise pollution on children’s health

Children are more prone to noise-induced hearing loss. According to one study, youngsters who are exposed to noise for 8 hours a day may have lasting hearing problems.

According to a paper published in The Indian Journal of Pediatrics, noise pollution can damage a child’s hearing at any stage of development. Loud noises at home or school may make it harder for children to learn.

They may have more difficulties with focus, communication, and cognitive functioning.

This can have an impact on a child’s behavior and capacity to develop connections and confidence. They may also acquire elevated blood pressure as a result of persistent sound exposure.

Ways to avoid noise pollution

Noise pollution is unavoidable in some situations. There are methods for reducing noise in the house. Someone can attempt to reduce the level of noise at home:

Reduce the noise produced by household appliances

Noise levels in the home can be increased by air conditioning systems, fans, and other equipment. Set a timer for them to only turn on at specific times.

Noise reduction from media devices

Take into account the level and duration of noise from televisions, computers, and video games. Avoid having unneeded noise playing in the background for extended periods, as well as listening to music or other shows at excessively loud volumes.

Setting aside time to watch TV or listen to music may be beneficial.

Noise sensitivity is also a sign of other disorders, such as hyperacusis (finding sounds unbearable). Your doctor will help diagnose it.

Noise pollution is an unseen threat. It may be found both on land and under the water. Noise pollution has an impact on the health and well-being of people and other creatures.

Noise pollution influences public health. It can cause stress, have an impact on mental health, and lead to the development of hearing problems. Noise pollution affects children more than adults.
