The Significance of Darkness and Sunlight for the Human Organism
Description
A contribution by Karin Michael
Karin Michael shows how deeply light and darkness shape our body, sleep, hormones, heart, concentration and even eye development – from the morning cortisol peak to liver regeneration in the deepest night. She vividly explains why children need real darkness, sunlight and screen-free times – and what silent damage chronic stress and blue light cause.
A contribution by Karin Michael for Dark Sky Week 2026.
