Streetlights in the skiing resort Kastelruth in South Tyrol. Medical research on the effects of excessive light on the human body suggests that a variety of adverse health effects may be caused by light pollution or excessive light exposure, and some lighting design textbooks  use human health as an explicit criterion for proper interior lighting. Health effects of over-illumination or improper spectral composition of light may include:
Light pollution, millions of children across the globe will never experience the Milky Way where they live. The increased and widespread use of artificial light at night is not only impairing our view of the universe, it is adversely affecting our environmentour safetyour energy consumption and our health.
What is Light Pollution? Most of us are familiar with air, water, and land pollution, but did you know that light can also be a pollutant? The inappropriate or excessive use of artificial light — known as light pollution — can have serious environmental consequences for humans, wildlife, and our climate.
Components of light pollution include: Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminated sporting venues.
The fact is that much outdoor lighting used at night is inefficient, overly bright, poorly targeted, improperly shielded, and, in many cases, completely unnecessary. If you live in an urban or suburban area all you have to do to see this type of pollution is go outside at night and look up at the sky.
Now, artificial lights overpower the darkness and our cities glow at night, disrupting the natural day-night pattern and shifting the delicate balance of our environment. The negative effects of the loss of this inspirational natural resource might seem intangible.
But a growing body of evidence links the brightening night sky directly to measurable negative impacts including.Light pollution: its real, destructive consequences are seldom recognized, but it is a problem with easy solutions that make economic sense.
|Dark Skies Awareness: Light pollution—what is it and why is it important to know?||Out of all the various pollutions humans create, light pollution gets the least attention. But light pollution is one of the most prevalent issues facing the developed and developing worlds today.|
|Light Pollution Impacts Animals and Environment||Humans have radically disrupted this cycle by lighting up the night. Scientific evidence suggests that artificial light at night has negative and deadly effects on many creatures including amphibians, birds, mammals, insects and plants.|
|Out of all the various pollutions humans create, light pollution gets the least attention.|
All living creatures rely on the Earth's regular rhythm of day and night to regulate internal cycles. Light in the wrong place at the wrong time can be intrusive.
There has been an increase in complaints about light to local authorities in recent years. This brochure looks at the different aspects of light pollution, explains the steps that can be taken to reduce it and describes what you can do if faced with the problem of pollution from light.

Light pollution, also known as photopollution, is the presence of anthropogenic light in the night vetconnexx.com is exacerbated by excessive, misdirected or obtrusive uses of light, but even carefully used light fundamentally alters natural conditions.
You may not know it, but light pollution contributes to carbon emissions and interferes with animal migration. Take these simple steps to reduce it. Light pollution can come in several forms: light trespass is when unwanted light escapes from one property into adjacent properties; over-illumination is using excessive light where it isn't needed; light clutter is the redundant clusters of lighting found in many urban centers; sky glow is the collective light pollution found over big cities.
