As humans have evolved, they have learnt to make the most of the daylight by resting through the night. They have managed to condition themselves to use the darkness. However, over the past few decades, traits and skills millennia of evolution have been hindered by the large amounts of light pollution. This has been affecting sleep cycles, often causing insomnia, which may lead to many psychological issues, such as irritability, fatigue, anxiety and often even depression.
Pradushana is a Sanskrit word meaning pollution. Here at Pradushana, we seek to spread awareness about this pollution.
Does Light Pollution Impact India?
India, a country with high population density, and a high level of urban population, is one of the worst offenders of light pollution. Over 58% of Indians live under high levels of light pollution, and almost nobody is unaffected by it.
What Causes Light Pollution?
One of the main reasons for this excessive light pollution is a lack of knowledge of light pollution, even among the highly educated, the government officials and lighting designers. Due to this, there is a distinct lack of research on the topic of light pollution, leading to data and discoveries being few and far between. This lack of knowledge and research also leads to ineffective lighting policies if they exist at all. This greatly hinders India’s fight against light pollution.
I am Arnav Kapoor, a 17 year old student of class 12, DPS RK Puram, looking to spread the word about light pollution.
My mission is to raise awareness and provide solutions as a means to reduce light pollution in India, create a community that will support the fight against Light Pollution, work with the government as well as the citizens to help create and enforce lighting policies to significantly reduce the menace of light pollution.
My Vision is to create awareness about the ecological impacts of light pollution in India by educating the masses about its causes and effects, and reducing its effects using a meaningful, simple and cost-effective approaches. Through Pradushana I hope to create a community of likeminded people dedicated to fighting light pollution. Pradushana envisions a future where effective, efficient and waste-free lighting provides a platform for humans to coexist with the environment.
What You Can Do For Light Pollution
POINT YOUR LIGHTS DOWNWARDS Pointing lighting, be it streetlamps, outdoor lighting fixtures, even indoor lights downwards, instead of towards the side has two effects: It reduces the light pollution, and it makes the lighting more effective. This is because pointing your lighting towards the side or upwards means that more light is escaping into the atmosphere, and less of the energy that you are consuming is actually being used.
USE WARM COLOURED LIGHTS Using warm coloured lights is a surprisingly effective tool in reducing your light footprint. Warm lights contain more red light, which does not get scattered easily compared to cooler blue lights, producing less light pollution. White and blue lights also tend to produce more glare, are harsher on the eyes, and are more harmful for plants and animals.
SHADE/COVER LIGHTS Even when pointed downwards, lamps, streetlights and lighting fixtures tend to project light upwards, causing immense light pollution. This can be amended by covering the tops of the light source, blocking the light and reflecting it back onto the ground, not only reducing light pollution, but also helps in getting more out of the energy consumed.
