valgustusreostuseta

Valgustusreostuseta is an Estonian term that translates to "light pollution-free" or "without light pollution." It refers to an area or a location that is intentionally kept dark, free from excessive or unwanted artificial light. This concept is crucial for preserving natural darkness, which is vital for various ecological, scientific, and aesthetic reasons.

Areas designated as valgustusreostuseta often aim to protect nocturnal wildlife, such as insects and migratory birds, which can be disoriented and harmed by artificial light at night. Astronomers and amateur stargazers also benefit from such areas, as the absence of light pollution allows for clearer and more detailed observation of celestial bodies. Furthermore, the presence of natural darkness contributes to human well-being by supporting natural circadian rhythms and offering a sense of tranquility.

Efforts to create valgustusreostuseta zones typically involve implementing responsible lighting practices. This includes using downward-directed lights, minimizing light intensity, employing warmer color temperatures, and only illuminating when and where necessary. Such initiatives can be found in national parks, nature reserves, and designated dark sky sites around the world, including in Estonia. The goal is to strike a balance between necessary artificial lighting for safety and human activity, and the preservation of natural darkness.
