A star-filled sky has long been a source of awe and inspiration, and its loss adversely affects human, nonhuman, and environmental health. In one generation, this majestic nighttime overstory has been lost due to national and international overuse of light-emitting diodes lighting. This article canvasses ill health effects of excessive light at night.

- Breast cancer is the top cause of cancer deaths for women around the world, and experts don't fully know why that is.
- It seems to be more common in highly industrialized countries, but it's also increasing in developing countries.
- New research suggests that exposure to electric light at night may disrupt our body’s natural rhythm and could be linked to higher breast cancer risk, leading to ideas on how to reduce this risk with better lighting practices.
The American Medical Association House of Delegates in June of 2012 adopted a policy statement on nighttime lighting and human health. This major policy statement summarizes the scientific evidence that nighttime electric light can disrupt circadian rhythms in humans and documents the rapidly advancing understanding from basic science of how disruption of circadian rhythmicity affects aspects of physiology with direct links to human health, such as cell cycle regulation, DNA damage response, and metabolism. The human evidence is also accumulating, with the strongest epidemiologic support for a link of circadian disruption from light at night to breast cancer.
