At night, bright street lamps, decorative lights on buildings, car lights, billboards and public facilities will all cause light pollution. During the day, we will also be disturbed by light pollution, such as glass and marble facades on buildings, and the reflection of sunlight will also affect our lives. You may have questions, so please look at the harm caused by light pollution with questions.

Improper lighting will make us feel annoyed. Our biological clock has been running according to the natural law of day and night cycle. Both metabolism, heart rate and body temperature are closely related to the biological clock. Under its command, we are full of energy during the day, but we have to sleep at night, and the activities of all organs will slow down and rest. Imagine that it was originally the time to go to bed at night, but due to the influence of too strong light, the biological clock is disordered and mistaken for daytime, so its activity is abnormal, then our body will definitely be affected, such as irritability, sleep disorder, headache and so on.

Improper lighting forced the Observatory to relocate. Since the establishment of 1878 in Tokyo, Japan, due to the influence of light pollution, few celestial bodies can be observed by large telescopes, so it has been relocated many times. Now only in remote mountainous areas without light pollution can you see the stars all over the sky.

Improper lighting is also one of the chief culprits of global warming. The global annual lighting electricity consumption exceeds 2 trillion kWh. If coal is used to produce this electricity, it will emit 2 billion tons of carbon dioxide and 60 million tons of sulfur dioxide, and global warming is mainly caused by carbon dioxide. In addition, lighting equipment will release a lot of heat, which is also an important reason for the rise of urban temperature.

The negative impact of light pollution is so serious, how to remedy it?

First of all, everyone should have the consciousness of reducing light pollution and take an active part in environmental protection activities.

In addition, more reasonable lighting tools should be designed to improve lighting conditions. You can also add a hood to make the place where light is needed bright without causing light pollution to the surrounding environment. Reduce the use of reflective materials such as glass and marble as the facade of buildings.

It is urgent to reduce light pollution. Let's act!
