Light Pollution Essay

A big amount of light plays a decisive role in your sleep.The human body refuses to adjust to the change of time or to adjust to it. Ruining your sleep can also change your mood and the way you do things.Losing sleep can also lack your concentration or memory level. An another effect is that it messes up a farmer's’ morning productivity.

Circadian rhythms disorders is simply a disruption in one’s circadian rhythms which is a name given for one’s internal body clock that regulates ones 24 hour cycle of biological processes. There are patterns of brain wave activity, hormone production, cell regeneration and other biological things that go along with ones 24 hour cycle.()

The article “Let There Be Dark” by Dan Hurley discussed the effects of light during the night and its effect on people’s health. It discusses many different studies and how some show this and how more still need to be done to be able to say for sure if artificial light at night leads to a higher risk of many health issues. These issues include obesity, Type 2 diabetes, breast cancer, prostate cancer, depression, and sleep loss. The studies focus on how light affects the body’s “circadian rhythm”. A circadian rhythm is the 24 hour cycle of the body which keeps the body in sync with the time. The body’s circadian rhythm is run by light signals collected by the eyes which results in a very sensitive rhythm of sleep, body temperature, release of

Typically, the environmental light cues that are perceived by the eyes signal the control center in the brain to reset the circadian rhythm every day back to 24 hours. In completely blind people, the environmental light cues are absent. Ultimately, the circadian rhythm is not reset every day back to 24 hours and the body functions as if day is night and night is day. Individuals with Non-24 mostly try to keep up with their everyday schedule. However, they face irresistible need to sleep during the day as they have difficult time sleeping or stay asleep at night. At some point, they can reach a point when their body clock is in sync with the typical day-night cycle again. Yet, it goes out of sync again quickly. In hopes to keep their body clock in sync, individuals force themselves to keep a normal schedule, going to work or school during the day and trying to sleep at night. As a result, they experience chronic sleep deficit, leading to “symptoms that can mimic depression, attention deficit hyperactivity disorder, chronic fatigue syndrome, fibromyalgia, or just plain fatigue” (circadian sleep disorders.org). Enduring health effects of sleep deprivation “include depression, lowered immune response, anxiety disorders, weight gain, fibromyalgia, diabetes, and cancer”. Living with this disorder is very difficult for people as it makes them to feel that they are in this alone, making

Light helps to regulate circadian rhythms, neuroendocrine responses, and seasonal cycles. (Brawley & Noell, 2008, Pages 2 & 11). Circadian rhythms help derive patterns of sleeping and eating. These circadian rhythms can be triggered by light and are

productive and happier. The large strength and varied colours of artificial lighting can be irritating and

Have you ever wondered what light pollution is? Light pollution is the effect of artificial lights on the night sky. The problems of light pollution in the United States includes the hampers of our view of some of life’s most spectacular sights, the harming of wildlife and it prevents us from seeing the night sky.

Aside from noticing night and day and clocks our body has its own system to tell us when to sleep and when to wake, our circadian rhythm. The human body naturally runs on a twenty five hour clock, so living on a twenty four hour schedule is often hard on the body because it loses an hour each day. On top of this natural loss most people do not get the right amount of sleep each night which can cause a whole host of problems. This is part of

There is a growing menace in today’s society known as light pollution. Light pollution is essentially excessive light from outside lighting fixtures that is misused and causes several negative effects. This increasing and perplexing issue is often magnified by industrialization and urban development which often neglects to consider the momentous problems light pollution causes. Despite serious efforts to minimize light pollution, “…light pollution rises about 6% every year” (Parks 30). One should know what light pollution entails, the adverse effects and costs of light pollution, ways it can be minimized, and how to appeal to the general public to help alleviate the problem.

Over time, human populations have been exponentially increasing. This growth has led to a major increase in demand for resources and space. To achieve their goals, humans have caused major changes in the surrounding ecosystems in many ways. First, they have cleared many areas thriving with organisms to build roads and cities destroying different ecosystems. Second, they have overharvested many species for food and resources causing many species to go extinct. Lastly, they have polluted natural habitats in numerous ways declining species biodiversity. Many people are familiar with pollution such as air pollution, trash pollution, and chemical pollution. However, a less apparent type of pollution that is equally important is the pollution of artificial lighting.

This report will discuss the advantages, disadvantages and details of both natural daylight and artificial lighting systems in terms of developing within a commercial property. The report provides detailed research and analysis concerning the subject topic in order to give a comprehensive view of various lighting types and methods. Light is an electromagnetic radiation visible to the human eye, the wavelengths visible to humans range between 380nm (nanometers) to 740nm. Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would.

Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is all among us but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue.

Earth is the only place in the universe that can support human life. It is very important that we realize this fact and take very good care of it. Various human activities cause the destruction of earth. Human beings can live a few days without food and water however humans can last only a few seconds without oxygen. Various human activities lead to the aggravation of the quality of air. Gases produced by human activities mainly due to exploitation of resources and industrialization cause air pollution. Green house gases mainly chlorofluorocarbons; carbon

Excessive use of light can contribute to a condition called light pollution. Light Pollution obstructs the view of the night sky, wastes energy, and similar to other types of pollution, is harmful for your health.

Pollution has become a major issue over the years because it contaminates the Earth’s environment and affects human health. While some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities. The increase of various types of pollution has made cancer pollutant more prevalent among the people, raising the risk of getting cancer. After being exposed to theses pollutants, the effects may be immediate or delayed. Some of the delayed effects, due to the exposure, can go unnoticed for many years. Another major issue that pollution creates is the tremendous cost for preventing and cleaning it up. However, we can not regulate the pollutants to the extent where there are no more possible
