Nighttime Blue Light Increases Fat Storage and Shortens Lifespan through Stress Responses in C. elegans

Artificial light at night (ALAN) may contribute to obesity and shortened lifespan in older adults.

• Light is a significant factor affecting physiological activities in organisms.
• The use of blue-light-rich LEDs in electronics leads to increased exposure to blue light.
• The prevalence of obesity is expected to rise among older adults as the population ages.
• ALAN is associated with potential increases in obesity rates and reduced lifespan.
• The exact mechanisms by which ALAN affects health outcomes are not well understood.
