Light at Night and Cancer Risk¶

Photochemistry and Photobiology, 2004
Environmental lighting powerfully suppresses the physiologic release of melatonin, which typically peaks in the middle of the night. This decreased melatonin production has been hypothesized to increase the risk of cancer. Evidence from experimental studies supports a link between melatonin and tumor growth.

Light at night, melatonin levels and nurses working at night

Lighting Research & Technology
Light at night has been implicated in health risks associated with night-shift work and circadian system disruption, but there are scant data on actual nighttime light exposures experienced by night-shift workers and how they affect melatonin levels.

Plant invasions under artificial light at night

Trends in Ecology & Evolution
Artificial light at night (ALAN) is a global change driver but how it interacts with plant invasions is unclear. Determining this requires understanding direct effects of ALAN on physiology, phenology, growth, and fitness of both invasive and native plant species and its indirect effects mediated through mutualistic and/or antagonistic interactions.

Artificial light at night

Abstract What is artificial light pollution, and how does it affect the behaviour of animals and, in turn, populations? In this chapter, we review key literature that has framed our understanding of the two mechanisms by which artificial light (as an individual stressor) shifts animal behaviour: altering the nocturnal photic landscape ...
