The many advancements in technology have made it possible to live in cities that stay bright all through the night. But, is there such a thing as too much light?
Many environmentalists and medical researchers say that the artificial light is not inherently bad because of all its benefits. But, there is a threshold where the sheer amount of light becomes inefficient and unnecessary; this is a level that experts call light pollution. According to researchers studying the phenomenon, this is the fastest and most pervasive form of environmental pollution, causing severe side effects in both humans and wildlife.
It is clear that the body needs time to shut down so that it can recuperate. But, when photons from either natural or artificial light hit the retina, it triggers the body to stop resting and get on with the day. This is a problem for both morning people and night owls, because most people routinely awaken at intervals during their sleep cycles, and having it cut short by light is a terrible inconvenience.
The ecological effects of light pollution are well documented. Trees have trouble adjusting to the change of seasons, nocturnal hunters have no idea when it’s time to look for food, and most animals have to change their breeding patterns.
There are ways you can protect yourself from the effects of light pollution. These methods range from complete window blockers to solar film windows. Another way to stave off the effects of light pollution is to raise awareness about what it can do to people and animals. Surveys show that people already know about light pollution, but few of them want to do anything about it.
