Light Pollution: Things you need to know

 With a civilized lifestyle, modern industry, rapid urbanization….people have used improperly or excessively artificial light at night and as a result, we are suffering from heavy light pollution. masonry.

What is light pollution?

Light pollution, photopollution, is the improper or excessive use of artificial light (anthropogenic light) especially at night. Therefore, light pollution is often the result of a civilized lifestyle, modern industry, rapid urbanization, etc.

There are many types of light pollution such as:

(2) skyglow bright area of the night sky over an inhabited area;

(3) Light trespas of light that penetrates unintentionally, unnecessarily; and

(4) Light clusters are groups of unhelpful light.

Harmful effects of light pollution

In light pollution, excess light will disrupt the ecosystem, disrupt the circadian rhythm of the day and night, and adversely affect the health of humans, animals and plants in the environment.

* Harm to animal and human health

Many medical studies show that light pollution has many harmful effects on human health including: headaches, fatigue, stress, sexual decline, anxiety, depression.

* Disrupt the ecosystem

Normal circadian rhythms are formed through coordination with the natural light-dark cycle, so disrupting this pattern affects ecological dynamics. Therefore, artificial light, used for night lighting, is also an important cause of ecosystem disturbance.

Scientists have shown that light pollution can be easily reversed and reversed with simple individual actions: Only use light in the necessary time and space; Do not use excessive lighting; Limit blue light (blue light); Protection, proper use of sunlight; Use curtains to prevent light from entering; Measure light pollution levels to standardize equipment, utensils, etc.
