lichtsmog

Lichtsmog, also known as light pollution, refers to the excessive or misdirected use of artificial light at night. It is a pervasive issue that impacts natural environments and human well-being. The primary sources of lichtsmog include streetlights, building illumination, advertising, and residential lighting. Its effects range from obscuring the night sky, making astronomical observation difficult, to disrupting natural ecosystems. Many nocturnal animals rely on darkness for navigation, foraging, and reproduction, and artificial light can interfere with these essential behaviors.

The biological impact extends to plants as well, affecting their growth patterns and seasonal cycles. For humans, chronic exposure to artificial light at night can disrupt circadian rhythms, which are the body's natural sleep-wake cycles. This disruption has been linked to various health problems, including sleep disorders, increased risk of obesity, and certain types of cancer. Environmental concerns also arise from the energy wasted by inefficient lighting, contributing to carbon emissions and resource depletion. Efforts to mitigate lichtsmog involve using shielded light fixtures that direct light downwards, employing warmer color temperatures, and implementing smart lighting controls that reduce illumination when and where it is not needed. Raising public awareness about the causes and consequences of lichtsmog is crucial for fostering more responsible lighting practices.
