Study Reveals Artificial Nighttime Lighting Disrupts Immune Systems in Mice, Raises Mortality
A study conducted at Tel Aviv University has found that artificial light at night (ALAN), even at intensities similar to street lighting, significantly disrupts the immune rhythms of wild rodents, leading to a 2.35-fold increase in mortality. The research, published in Environmental Pollution, was carried out on two species of spiny mice in semi-natural conditions. The study revealed that exposure to ALAN disrupted the timing of the mice's immune and endocrine systems, impairing their survival. The researchers observed that the immune systems of the mice exposed to ALAN stopped functioning effectively, leading to their death. This study is the first to establish a connection between ALAN and weakened immunity in mammals, suggesting broader implications for all living creatures, including humans.
