Feb 12, 2025

Artificial Light at Night (ALAN) disrupts our natural rhythms, affecting everything from cognition to emotional regulation. It hinders melatonin production, impacting sleep and immune function. Chronic exposure can lead to serious issues like eye damage and metabolic dysfunction, messing with processes in the liver and pancreas. ALAN also alters gut health, contributing to inflammation and various diseases like obesity and diabetes. Strategies to minimize its effects, such as using warm lights and reducing screen time before bed, are shared for better health.
