Modern energy-efficient lighting has significantly altered human light exposure patterns since the 2000s, potentially affecting mitochondrial function at the cellular level. Research suggests these changes in light exposure may be contributing to metabolic disorders including diabetes and neurodegenerative conditions such as dementia. The shift toward different lighting technologies in buildings has created an unintended biological impact on human physiology.


This research highlights a previously underrecognized health consequence of energy-efficient building practices that affect billions of people daily. Understanding the connection between artificial lighting and mitochondrial health could inform better lighting design standards and potentially help address rising rates of metabolic and neurological diseases.
