Artificial light can disturb natural body rhythms in both humans and animals. This can result in sleep deprivation, fatigue, headaches, stress, anxiety, and other health problems.

When we don’t get affected by artificial light, our bodies produce more of the hormone melatonin that causes us to sleep better and increases our overall health.

Light pollution can disorient animals and cause problems when they try to navigate in the wild. Many species use the horizon and stars for orientation.

With only the help of natural light, like the moon, turtles and their hatchlings have a better chance of surviving and finding the way back to the ocean and their group.
