According to the World Health Organization, “A number of environmental factors have been linked to increased risk of cardiovascular disease and diabetes in the developing world, and light pollution is one of them.”
A number of different light pollution sources have been found to be responsible for light pollution.
The WHO lists the following as “light pollution sources” that can cause light pollution: direct sunlight from buildings, cars, and vehicles; indoor lighting (lights that can be set at night, which can cause the sun to shine during the day); street lights; fluorescent lights; and fluorescent tubes.
Light pollution also causes indoor air pollution.
A study in 2016 by the World Economic Forum and the International Monetary Fund concluded that the costs of light pollution are about $6.4 trillion per year in the developed world, with the highest impact on people living in urban areas.
According to the International Council for Light-Emitting Diodes, a group of lighting manufacturers, light pollution can be reduced with proper lighting practices.
“The most important thing for anyone looking to protect themselves from light pollution, and reduce their exposure to harmful and potentially damaging light, is to understand the light pollution factors, including the sources, their effects, and how to reduce them,” the group says.
According the Light Pollution Foundation, light-pollution causes a range of health effects: from reduced immunity to lower blood pressure and heart rate; increased skin sensitivity; and decreased ability to metabolize light, as well as reduced concentration of vitamin D in the blood.
“Light pollution can also have a negative impact on our health,” the foundation says.
“It affects our skin and hair and reduces our ability to fight infections.
We also tend to overreact to sunlight and the way we interact with the light.
This causes us to be less alert and more irritable.”
Light pollution is also a major contributor to ozone levels in the air, and in many parts of the world, a large proportion of our energy comes from the combustion of fossil fuels.
According the EPA, light exposure can contribute to over-exposure to ozone, as can indoor pollution.
As a result, it’s important to reduce your exposure to light pollution as much as possible, and be sure to check your local city or town ordinances to ensure that your light pollution guidelines are being followed.
