Valgusreostus, also known as light pollution, refers to the excessive or misdirected use of artificial light, particularly outdoors. This phenomenon can have significant impacts on human health, wildlife, and astronomical observation.

Excessive artificial light at night can disrupt natural circadian rhythms in humans, potentially leading to sleep disorders, mood disturbances, and other health issues. For wildlife, light pollution can interfere with navigation, foraging, reproduction, and predator-prey dynamics. Migratory birds, insects, and nocturnal animals are particularly vulnerable to these disruptions.

The dimming of the night sky due to artificial lighting also hinders astronomical research and stargazing. The faint light from distant stars and galaxies is obscured by the glow of human settlements.

Common sources of valgusreostus include streetlights, building illumination, sports stadiums, and advertising signs. Strategies to mitigate light pollution involve using shielded fixtures that direct light downwards, employing lower intensity lighting, and implementing smart lighting controls that reduce or turn off lights when not needed. Preserving natural darkness is increasingly recognized as an important environmental concern.
