BioClock featured on Dutch children’s TV: Light pollution in Het Klokhuis

How does artificial light at night affect the natural world — and our sleep? A recent episode of Het Klokhuis, a Dutch educational TV show for children, explores the science behind light pollution, featuring BioClock researcher Kamiel Spoelstra (NIOO-KNAW).

Kamiel explains how streetlights can confuse insects, delay trees from shedding their leaves, and leave animals more exposed. The episode also links excessive nighttime lighting to disturbed human sleep.

Filmed partly in Lauwersmeer National Park, one of the Netherlands’ darkest regions, the show invites viewers to experience what true darkness means for both nature and health.
